A variety of sources, including animal wastes, municipal solid wastes, sewage and agricultural wastes may be used to produce biogas in an anaerobic process. The main forming material of biogas is methane gas, which can be used directly in a variety of ways, such as heating and as fuel, which is very common in a number of countries, such as China and India. In this article, the cost of biogas production from animal fertilizers, and its refined form, bio methane gas has been studied and it is shown that it can be an alternative for natural gas in terms of costs, in the near future. The cost of biogas purification to biomethane is more than three times the cost of biogas production for an average unit. Biomethane production costs, calculated for a small unit, is about $9/MMBTU and for an average unit is about $5.9/MMBTU. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=biomethane" title=" biomethane"> biomethane</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20evaluation" title=" economic evaluation"> economic evaluation</a> </p> <a href="https://publications.waset.org/abstracts/18740/economic-evaluation-of-biogas-and-biomethane-from-animal-manure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18740.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">490</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7496</span> Production of Biogas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20O.%20Alabi">J.

Anaerobic bacteria inside biodigesters break down biomass to produce biogas. (Which is 70% methane)? Currently there is no simple way to compress and store biogas. So, in order to use biogas as a source of energy, a direct feed from biodigeser to the store tap or heater must be made. Any excess biogas is vented into the atmosphere, which is wasteful and car have a negative effect on the environment, we have been tasked with designing a system that will be able to compress biogas using an off-grid power supply, making the biogas portable and makes through the use of large-scale, shared biodigester. Our final design is a system that maximizes simplicity and safety while minimizing cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=biodigesters" title=" biodigesters"> biodigesters</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20fuel" title=" natural fuel"> natural fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=bionanotechnology" title=" bionanotechnology"> bionanotechnology</a> </p> <a href="https://publications.waset.org/abstracts/27399/production-of-biogas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27399.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">364</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7495</span> Experimental Research of Biogas Production by Using Sewage Sludge and Chicken Manure Bioloadings with Wood Biochar Additive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Baltrenas">P.

In this research, a batch bioreactor with a mechanical mixer was used for biogas production from sewage sludge and chicken manure bioloadings. The process of anaerobic digestion was mesophilic (35 °C). Produced biogas was stoted in a gasholder and the concentration of its components was measured with INCA 4000 biogas analyser. Also, a specific additive (pine wood biochar) was applied to prepare bioloadings. The application of wood biochar in bioloading increases the CH₄ concentration in the produced gas by 6-7%. The highest concentrations of CH₄ were found in biogas produced during the decomposition of sewage sludge bioloadings. The maximum CH₄ reached 77.4%. Studies have shown that the application of biochar in bioloadings also reduces average CO₂ and H₂S concentrations in biogas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biochar" title="biochar">biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=bioreactor" title=" bioreactor"> bioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=sewage%20sludge" title=" sewage sludge"> sewage sludge</a> </p> <a href="https://publications.waset.org/abstracts/101582/experimental-research-of-biogas-production-by-using-sewage-sludge-and-chicken-manure-bioloadings-with-wood-biochar-additive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101582.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7494</span> Risk Assessment Results in Biogas Production from Agriculture Biomass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandija%20Zeverte-Rivza">Sandija Zeverte-Rivza</a>, <a href="https://publications.waset.org/abstracts/search?q=Irina%20Pilvere"> Irina Pilvere</a>, <a href="https://publications.waset.org/abstracts/search?q=Baiba%20Rivza"> Baiba Rivza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of renewable energy sources incl. biogas has become topical in accordance with the increasing demand for energy, decrease of fossil energy resources and the efforts to reduce greenhouse gas emissions as well as to increase energy independence from the territories where fossil energy resources are available. As the technologies of biogas production from agricultural biomass develop, risk assessment and risk management become necessary for farms producing such a renewable energy. The need for risk assessments has become particularly topical when discussions on changing the biogas policy in the EU take place, which may influence the development of the sector in the future, as well as the operation of existing biogas facilities and their income level. The current article describes results of the risk assessment for farms producing biomass from agriculture biomass in Latvia, the risk assessment system included 24 risks, that affect the whole biogas production process and the obtained results showed the high significance of political and production risks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas%20production" title="biogas production">biogas production</a>, <a href="https://publications.waset.org/abstracts/search?q=risks" title=" risks"> risks</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=biosystems%20engineering" title=" biosystems engineering"> biosystems engineering</a> </p> <a href="https://publications.waset.org/abstracts/6649/risk-assessment-results-in-biogas-production-from-agriculture-biomass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6649.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7493</span> Temperature Susceptibility for Optimal Biogas Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ujjal%20Chattaraj">Ujjal Chattaraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Pbharat%20Saikumar"> Pbharat Saikumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Thinley%20Dorji"> Thinley Dorji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Earth is going to be a planet where no further life can sustain if people continue to pollute the environment. We need energy and fuels everyday for heating and lighting purposes in our life. It’s high time we know this problem and take measures at-least to reduce pollution and take alternative measures for everyday livelihood. Biogas is one of them. It is very essential to define and control the parameters for optimization of biogas production. Biogas plants can be made of different size, but it is very vital to make a biogas which will be cost effective, with greater efficiency (more production) and biogas plants that will sustain for a longer period of time for usage. In this research, experiments were carried out only on cow dung and Chicken manure depending on the substrates people out there (Bhutan) used. The experiment was done within 25 days and was tested for different temperatures and found out which produce more amount. Moreover, it was also statistically tested for their dependency and non-dependency which gave clear idea more on their production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digester" title="digester">digester</a>, <a href="https://publications.waset.org/abstracts/search?q=mesophilic%20temperature" title=" mesophilic temperature"> mesophilic temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20manure" title=" organic manure"> organic manure</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=thermophilic%20temperature" title=" thermophilic temperature"> thermophilic temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=t-test" title=" t-test"> t-test</a> </p> <a href="https://publications.waset.org/abstracts/54436/temperature-susceptibility-for-optimal-biogas-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54436.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7492</span> Biogas Production from Lake Bottom Biomass from Forest Management Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dessie%20Tegegne%20Tibebu">Dessie Tegegne Tibebu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kirsi%20Mononen"> Kirsi Mononen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ari%20Pappinen"> Ari Pappinen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In areas with forest management, agricultural, and industrial activity, sediments and biomass are accumulated in lakes through drainage system, which might be a cause for biodiversity loss and health problems. One possible solution can be utilization of lake bottom biomass and sediments for biogas production. The main objective of this study was to investigate the potentials of lake bottom materials for production of biogas by anaerobic digestion and to study the effect of pretreatment methods for feed materials on biogas yield. In order to study the potentials of biogas production lake bottom materials were collected from two sites, Likokanta and Kutunjärvi lake. Lake bottom materials were mixed with straw-horse manure to produce biogas in a laboratory scale reactor. The results indicated that highest yields of biogas values were observed when feeds were composed of 50% lake bottom materials with 50% straw horse manure mixture-while with above 50% lake bottom materials in the feed biogas production decreased. CH4 content from Likokanta lake materials with straw-horse manure and Kutunjärvi lake materials with straw-horse manure were similar values when feed consisted of 50% lake bottom materials with 50% straw horse manure mixtures. However, feeds with lake bottom materials above 50%, the CH4 concentration started to decrease, impairing gas process. Pretreatment applied on Kutunjärvi lake materials showed a slight negative effect on the biogas production and lowest CH4 concentration throughout the experiment. The average CH4 production (ml g-1 VS) from pretreated Kutunjärvi lake materials with straw horse manure (208.9 ml g-1 VS) and untreated Kutunjärvi lake materials with straw horse manure (182.2 ml g-1 VS) were markedly higher than from Likokanta lake materials with straw horse manure (157.8 ml g-1 VS). According to the experimental results, utilization of 100% lake bottom materials for biogas production is likely to be impaired negatively. In the future, further analyses to improve the biogas yields, assessment of costs and benefits is needed before utilizing lake bottom materials for the production of biogas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=lake%20bottom%20materials" title=" lake bottom materials"> lake bottom materials</a>, <a href="https://publications.waset.org/abstracts/search?q=sediments" title=" sediments"> sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=pretreatment" title=" pretreatment"> pretreatment</a> </p> <a href="https://publications.waset.org/abstracts/34770/biogas-production-from-lake-bottom-biomass-from-forest-management-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34770.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7491</span> Utilization of Kitchen Waste inside Green House Chamber: A Community Level Biogas Programme </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravi%20P.%20Agrahari">Ravi P.

The field study was carried out for one month (January 19, 2012– February 17, 2012) at Centre for Energy Studies, IIT Delhi, New Delhi, India. This study involves the uses of greenhouse canopy to increase the temperature for the production of biogas in winter period. In continuation, a semi-continuous study was conducted for one month with the retention time of 30 days under batch system. The gas generated from the biogas plant was utilized for cooking (burner) and lighting (lamp) purposes. Gas productions in the winter season registered lower than other months. It can be concluded that the solar greenhouse assisted biogas plant can be efficiently adopted in colder region or in winter season because temperature plays a major role in biogas production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20house%20chamber" title=" green house chamber"> green house chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20material" title=" organic material"> organic material</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20intensity" title=" solar intensity"> solar intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=batch%20system" title=" batch system"> batch system</a> </p> <a href="https://publications.waset.org/abstracts/1386/utilization-of-kitchen-waste-inside-green-house-chamber-a-community-level-biogas-programme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1386.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">395</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7490</span> Enhance Biogas Production by Enzymatic Pre-Treatment from Palm Oil Mill Effluent (POME)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Tajul%20Islam">M.

Many studies on pretreatments especially chemical and physical processes are carried out to evaluate the anaerobic digestion for enhanced biogas production. Among the pretreatment methods acid and alkali pre-treatments gained the highest importance. Previous studies have showed that although acid and alkali pretreatment has significant effect on degradation of biomass, these methods have some negative impact on environment due to their hazard in nature while enzymatic pre-treatment is environmentally friendly. One of the constrains to use of enzyme in pretreatment process for biogas production is high cost which is currently focused to reduce cost through fermentation of waste-based media. As such palm oil mill effluent (POME) as an abundant resource generated during palm oil processing at mill is being used a potential fermentation media for enzyme production. This low cost of enzyme could be an alternative to biogas pretreatment process. This review is to focus direct application of enzyme as enzymatic pre-treatment on POME to enhanced production of biogas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=POME" title="POME">POME</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymatic%20pre-treatment" title=" enzymatic pre-treatment"> enzymatic pre-treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic%20biomass" title=" lignocellulosic biomass"> lignocellulosic biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a> </p> <a href="https://publications.waset.org/abstracts/21350/enhance-biogas-production-by-enzymatic-pre-treatment-from-palm-oil-mill-effluent-pome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21350.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">550</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7489</span> Enhancing of Biogas Production from Slaughterhouse and Dairy Farm Waste with Pasteurization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Hassan%20Onsa">Mahmoud Hassan Onsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Saadelnour%20Abdueljabbar%20Adam"> Saadelnour Abdueljabbar Adam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wastes from slaughterhouses in most towns in Sudan are often poorly managed and sometimes discharged into adjoining streams due to poor implementation of standards, thus causing environmental and public health hazards and also there is a large amount of manure from dairy farms.

The highest biogas output 2.9 mL/g dry matter/day (from bio-digester2) together with a high quality biogas of 87.4% methane content which is useful for combustion and energy production and healthy bio-fertilizer but biodigester1 gave 1.68 mL/g dry matter/day with methane content 85% which is useful for combustion, energy production and can be considered as new technology of dryer bio-digesters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-digester" title=" bio-digester"> bio-digester</a>, <a href="https://publications.waset.org/abstracts/search?q=blood" title=" blood"> blood</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%20manure" title=" cow manure"> cow manure</a>, <a href="https://publications.waset.org/abstracts/search?q=rumen%20content" title=" rumen content"> rumen content</a> </p> <a href="https://publications.waset.org/abstracts/27392/enhancing-of-biogas-production-from-slaughterhouse-and-dairy-farm-waste-with-pasteurization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27392.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">727</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7488</span> Exploring the Viability of Biogas Energy Potential in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solomon%20Eghosa%20Uhunamure">Solomon Eghosa Uhunamure</a>, <a href="https://publications.waset.org/abstracts/search?q=Karabo%20Shale"> Karabo Shale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biogas technology has emerged as a promising solution for sustainable development, enhancing energy security while mitigating environmental hazards. Interest in biogas for household energy is growing due to its potential to address both energy and waste management challenges. To ensure biogas production contributes meaningfully to South Africa's future energy landscape, understanding public perceptions is essential for shaping effective policy measures. A household survey revealed that lower awareness of biogas correlates with reduced social and cultural acceptance, however, after providing basic information—such as a definition, a diagram, or one of two simple messages—support for biogas increased by 10% to 15% compared to the baseline. These findings highlight the critical role of awareness in building support for biogas as a key component of South Africa's decarbonization strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=awareness" title="awareness">awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=barriers" title=" barriers"> barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20benefits" title=" environmental benefits"> environmental benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/189231/exploring-the-viability-of-biogas-energy-potential-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189231.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">32</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7487</span> A Feasibility Study of Waste (d) Potential: Synergistic Effect Evaluation by Co-digesting Organic Wastes and Kinetics of Biogas Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunwar%20Paritosh">Kunwar Paritosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Mathur"> Sanjay Mathur</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Yadav"> Monika Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Paras%20Gandhi"> Paras Gandhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Subodh%20Kumar"> Subodh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nidhi%20Pareek"> Nidhi Pareek</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivekanand%20Vivekanand"> Vivekanand Vivekanand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A significant fraction of energy is wasted every year managing the biodegradable organic waste inadequately as development and sustainability are the inherent enemies. The management of these waste is indispensable to boost its optimum utilization by converting it to renewable energy resource (here biogas) through anaerobic digestion and to mitigate greenhouse gas emission. Food and yard wastes may prove to be appropriate and potential feedstocks for anaerobic co-digestion for biogas production. The present study has been performed to explore the synergistic effect of co-digesting food waste and yard trimmings from MNIT campus for enhanced biogas production in different ratios in batch tests (37±10C, 90 rpm, 45 days). The results were overwhelming and showed that blending two different organic waste in proper ratio improved the biogas generation considerably, with the highest biogas yield (2044±24 mLg-1VS) that was achieved at 75:25 of food waste to yard waste ratio on volatile solids (VS) basis. The yield was 1.7 and 2.2 folds higher than the mono-digestion of food or yard waste (1172±34, 1016±36mLg-1VS) respectively. The increase in biogas production may be credited to optimum C/N ratio resulting in higher yield. Also Adding TiO2 nanoparticles showed virtually no effect on biogas production as sometimes nanoparticles enhance biogas production. ICP-MS, FTIR analysis was carried out to gain an insight of feedstocks. Modified Gompertz and logistics models were applied for the kinetic study of biogas production where modified Gompertz model showed goodness-of-fit (R2=0.9978) with the experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20co-digestion" title="anaerobic co-digestion">anaerobic co-digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20waste" title=" organic waste"> organic waste</a> </p> <a href="https://publications.waset.org/abstracts/57413/a-feasibility-study-of-waste-d-potential-synergistic-effect-evaluation-by-co-digesting-organic-wastes-and-kinetics-of-biogas-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">387</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7486</span> IoT and Advanced Analytics Integration in Biogas Modelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Choudhary">Rakesh Choudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajay%20Kumar"> Ajay Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Sharma"> Deepak Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal of this paper is to investigate the challenges and benefits of IoT integration in biogas production. This overview explains how the inclusion of IoT can enhance biogas production efficiency. Therefore, such collected data can be explored by advanced analytics, including Artificial intelligence (AI) and Machine Learning (ML) algorithms, consequently improving bio-energy processes. To boost biogas generation efficiency, this report examines the use of IoT devices for real-time data collection on key parameters, e.g., pH, temperature, gas composition, and microbial growth. Real-time monitoring through big data has made it possible to detect diverse, complex trends in the process of producing biogas. The Informed by advanced analytics can also help in improving bio-energy production as well as optimizing operational conditions. Moreover, IoT allows remote observation, control and management, which decreases manual intervention needed whilst increasing process effectiveness. Such a paradigm shift in the incorporation of IoT technologies into biogas production systems helps to achieve higher productivity levels as well as more practical biomass quality biomethane through real-time monitoring-based proactive decision-making, thus driving continuous performance improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title="internet of things">internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20monitoring" title=" real-time monitoring"> real-time monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/189359/iot-and-advanced-analytics-integration-in-biogas-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189359.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">20</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7485</span> The Effect of System Parameters on the Biogas Production from Poultry Rendering Plant Anaerobic Digesters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Lovanh">N.

The green energy derived from animal wastes is considered to be carbon neutral and offsetting those generated from fossil fuels. In this study, an evaluation of system parameters on methane production from anaerobic digesters utilizing poultry rendering plant wastewater was carried out. Anaerobic batch reactors and continuous flow system subjected to different operation conditions (i.e., flow rate, temperature, and etc.) containing poultry rendering wastewater were set up to evaluate methane potential from each scenario. Biogas productions were sampled and monitored by gas chromatography and photoacoustic gas analyzer over six months of operation. The results showed that methane productions increased as the temperature increased. However, there is an upper limit to the increase in the temperature on the methane production. Flow rates and type of systems (batch vs. plug-flow regime) also had a major effect on methane production. Constant biogas production was observed in plug-flow system whereas batch system produced biogas quicker and tapering off toward the end of the six-month study. Based on these results, it is paramount to consider operating conditions and system setup in optimizing biogas production from agricultural wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=methane" title=" methane"> methane</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry%20rendering%20wastewater" title=" poultry rendering wastewater"> poultry rendering wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechnology" title=" biotechnology"> biotechnology</a> </p> <a href="https://publications.waset.org/abstracts/27658/the-effect-of-system-parameters-on-the-biogas-production-from-poultry-rendering-plant-anaerobic-digesters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27658.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7484</span> Integrated Process Modelling of a Thermophilic Biogas Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Obiora%20E.%20Anisiji">Obiora E.

It aimed at integrating thermodynamics; which deals with the direction in which a process occurs and Biochemical kinetics; which gives the understanding of the rates of biochemical reaction. The mathematical formulation of the proposed gas plant follows the fundamental principles of thermodynamics, and further analysis were accomplished to develop an algorithm for evaluating the plant performance preferably in terms of daily production capacity. In addition, the capacity of the plant is equally estimated for a given cycle of operation and presented in time histories. A nominal 1500m3 biogas plant was studied characteristically and its performance efficiency evaluated. It was observed that the rate of biogas production is essentially a function of enthalpy ratio, the reactor temperature, pH, substrate concentration, rate of degradation of the biomass, and the accumulation of matter in the system due to bacteria growth. The results of this study conform to a very large extent with reported empirical data of some existing plant and further model validations were conducted in line with classical records found in literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas%20plant" title=" biogas plant"> biogas plant</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas%20production" title=" biogas production"> biogas production</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-reactor" title=" bio-reactor"> bio-reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=rate%20of%20production" title=" rate of production"> rate of production</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=therm" title=" therm"> therm</a> </p> <a href="https://publications.waset.org/abstracts/21926/integrated-process-modelling-of-a-thermophilic-biogas-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21926.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">435</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7483</span> Optimization of Process Parameters Affecting Biogas Production from Organic Fraction of Municipal Solid Waste via Anaerobic Digestion </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Sajeena%20Beevi">B.

As POME from different sources have varying characteristics due to different process flows in mills, there is no ideal treatment parameters for POME. Hence, different treatment plants alter different parameters in anaerobic digestion to achieve desired biogas production levels and to meet POME waste discharge limits. The objective of this study is to evaluate the performance of mesophilic anaerobic digestion in four different biogas plants in Malaysia. Aspects of POME pre-treatment efficiency, analysis of treated POME and AD’s bottom sludge characteristics, including several parameters like chemical oxygen demand (COD), biological oxygen demand (BOD), total solid (TS) removal in the effluent, pH and temperature changes, total biogas produced, the composition of biogas including methane (CH₄), carbon dioxide (CO₂), hydrogen sulfide (H₂S) and oxygen (O₂) were investigated. The effect of organic loading rate (OLR) and hydraulic retention time (HRT) on anaerobic digester performance is also evaluated. In pre-treatment, it is observed that BGP B has the lowest average outlet temperature of 40.41°C. All BGP shows a high-temperature fluctuation (36 to 49 0C) and good pH readings (minimum 6.7), leaving the pre-treatment facility before entering the AD.COD removal of POME is considered good, with an average of 78% and maximum removal of 85%. BGP C has the lowest average COD and TS content in treated POME, 13,313 mg/L, and 12,048 mg/L, respectively. However, it is observed that the treated POME leaving all ADs, still contains high-quality organic substances (COD between 12,000 to 19,000 mg/L) that might be able to digest further to produce more biogas. The biogas produced in all four BGPs varies due to different COD loads. BGP B has the highest amount of biogas produced, 378,874.7 Nm³/month, while BGP D has the lowest biogas production of 272,378.5 Nm³/month. Furthermore, the composition of biogas produced in all plants is well within literature values (CH4 between 55 to 65% and CO₂ between 32 to 36%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20oil%20mill%20effluent" title="palm oil mill effluent">palm oil mill effluent</a>, <a href="https://publications.waset.org/abstracts/search?q=in-ground%20lagoon%20anaerobic%20digester" title=" in-ground lagoon anaerobic digester"> in-ground lagoon anaerobic digester</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a> </p> <a href="https://publications.waset.org/abstracts/156202/a-comparative-analysis-of-the-performances-of-four-different-in-ground-lagoons-anaerobic-digesters-in-the-treatment-of-palm-oil-mill-effluent-pome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156202.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7480</span> Pineapple Waste Valorization through Biogas Production: Effect of Substrate Concentration and Microwave Pretreatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khamdan%20Cahyari">Khamdan Cahyari</a>, <a href="https://publications.waset.org/abstracts/search?q=Pratikno%20Hidayat"> Pratikno Hidayat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia has produced more than 1.8 million ton pineapple fruit in 2013 of which turned into waste due to industrial processing, deterioration and low qualities. It was estimated that this waste accounted for more than 40 percent of harvested fruits. In addition, pineapple leaves were one of biomass waste from pineapple farming land, which contributed even higher percentages. Most of the waste was only dumped into landfill area without proper pretreatment causing severe environmental problem. This research was meant to valorize the pineapple waste for producing renewable energy source of biogas through mesophilic (30℃) anaerobic digestion process. Especially, it was aimed to investigate effect of substrate concentration of pineapple fruit waste i.e. peel, core as well as effect of microwave pretreatment of pineapple leaves waste. The concentration of substrate was set at value 12, 24 and 36 g VS/liter culture whereas 800-Watt microwave pretreatment conducted at 2 and 5 minutes. It was noticed that optimum biogas production obtained at concentration 24 g VS/l with biogas yield 0.649 liter/g VS (45%v CH4) whereas microwave pretreatment at 2 minutes duration performed better compare to 5 minutes due to shorter exposure of microwave heat. This results suggested that valorization of pineapple waste could be carried out through biogas production at the aforementioned process condition. Application of this method is able to both reduce the environmental problem of the waste and produce renewable energy source of biogas to fulfill local energy demand of pineapple farming areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pineapple%20waste" title="pineapple waste">pineapple waste</a>, <a href="https://publications.waset.org/abstracts/search?q=substrate%20concentration" title=" substrate concentration"> substrate concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20pretreatment" title=" microwave pretreatment"> microwave pretreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a> </p> <a href="https://publications.waset.org/abstracts/39506/pineapple-waste-valorization-through-biogas-production-effect-of-substrate-concentration-and-microwave-pretreatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39506.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">580</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7479</span> Investigation of Biogas from Slaughterhouse and Dairy Farm Waste </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saadelnour%20Abdueljabbar%20Adam">Saadelnour Abdueljabbar Adam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wastes from slaughterhouses in most towns in Sudan are often poorly managed and sometimes discharged into adjoining streams due to poor implementation of standards, thus causing environmental and public health hazards and also there is a large amount of manure from dairy farms. This paper presents a solution of organic waste from cow dairy farms and slaughterhouse. We present the findings of experimental investigation of biogas production using cow manure, blood and rumen content were mixed at three proportions :72.3%, 61%, 39% manure, 6%, 8.5%, 22% blood; and 21.7%, 30.5%, 39% rumen content in volume for bio-digester 1,2,3 respectively. This paper analyses the quantitative and qualitative composition of biogas: gas content, and the concentration of methane. The highest biogas output 0.116L/g dry matter from bio-digester1 together with a high-quality biogas of 85% methane Was from the mixture of cow manure with blood and rumen content were mixed at 72.3%manure, 6%blood and 21.7%rumen content which is useful for combustion and energy production.

However, due to the property and composition of rice straw, it is difficult to be degraded by hydrolysis enzymes. One of the pretreatment method that modifies such properties of lignocellulosic biomass is the application of lignocellulose-degrading microbial consortia. The aim of this study is to investigate the effect of microbial consortia to enhance biogas production. To select the high efficient consortium, cellulase enzymes were extracted and their activities were analyzed. The results suggested that microbial consortium culture obtained from cattle manure is the best candidate compared to decomposed wood and horse manure. A microbial consortium isolated from cattle manure was then mixed with anaerobic sludge and used as inoculum for biogas production. The optimal conditions for biogas production were investigated using response surface methodology (RSM). The tested parameters were the ratio of amount of microbial consortium isolated and amount of anaerobic sludge (MI:AS), substrate to inoculum ratio (S:I) and temperature. Here, the value of the regression coefficient R2 = 0.7661 could be explained by the model which is high to advocate the significance of the model. The highest cumulative biogas yield was 104.6 ml/g-rice straw at optimum ratio of MI:AS, ratio of S:I, and temperature of 2.5:1, 15:1 and 44°C respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lignocellulolytic%20biomass" title="lignocellulolytic biomass">lignocellulolytic biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20consortium" title=" microbial consortium"> microbial consortium</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulase" title=" cellulase"> cellulase</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=Response%20Surface%20Methodology%20%28RSM%29" title=" Response Surface Methodology (RSM)"> Response Surface Methodology (RSM)</a> </p> <a href="https://publications.waset.org/abstracts/21514/analysis-of-a-lignocellulose-degrading-microbial-consortium-to-enhance-the-anaerobic-digestion-of-rice-straws" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7477</span> Development of Simple-To-Apply Biogas Kinetic Models for the Co-Digestion of Food Waste and Maize Husk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Owamah%20Hilary">Owamah Hilary</a>, <a href="https://publications.waset.org/abstracts/search?q=O.%20C.%20Izinyon"> O.

Biodegradability kinetic (BIK) model and maximum biogas production potential and stability assessment (MBPPSA) model were therefore developed in this study for the anaerobic co-digestion of food waste and maize husk. Biodegradability constant (k) was estimated as 0.11d-1 using the BIK model. The results of maximum biogas production potential (A) obtained using the MBPPSA model corresponded well with the results obtained using the popular but complex modified Gompertz model for digesters B-1, B-2, B-3, B-4, and B-5. The (If) value of MBPPSA model also showed that digesters B-3, B-4, and B-5 were stable, while B-1 and B-2 were unstable. Similar stability observation was also obtained using the modified Gompertz model. The MBPPSA model can therefore be used as alternative model for anaerobic digestion feasibility studies and plant design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=inoculum" title=" inoculum"> inoculum</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20development" title=" model development"> model development</a>, <a href="https://publications.waset.org/abstracts/search?q=stability%20assessment" title=" stability assessment "> stability assessment </a> </p> <a href="https://publications.waset.org/abstracts/28007/development-of-simple-to-apply-biogas-kinetic-models-for-the-co-digestion-of-food-waste-and-maize-husk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28007.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">429</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7476</span> Biogas Production from University Canteen Waste: Effect of Organic Loading Rate and Retention Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khamdan%20Cahyari">Khamdan Cahyari</a>, <a href="https://publications.waset.org/abstracts/search?q=Gumbolo%20Hadi%20Susanto"> Gumbolo Hadi Susanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Pratikno%20Hidayat"> Pratikno Hidayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukirman"> Sukirman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> University canteen waste was used as raw material to produce biogas in Faculty of Industrial Technology, Islamic University of Indonesia. This faculty was home to more than 3000 students and lecturers who work and study for 5 days/week (8 hours/day). It produced approximately 85 ton/year organic fraction of canteen waste. Yet, this waste had been dumped for years in landfill area which cause severe environmental problems. It was proposed to utilize the waste as raw material for producing renewable energy source of biogas. This research activities was meant to investigate the effect of organic loading rate (OLR) and retention time (RT) of continuous anaerobic digestion process for 200 days. Organic loading rate was set at value 2, 3, 4 and 5 g VS/l/d whereas the retention time was adjusted at 30, 24, 18 and 14.4 days. Optimum condition was achieved at OLR 4 g VS/l/d and RT 24 days with biogas production rate between 0.75 to 1.25 liter/day (40-60% CH4). This indicated that the utilization of canteen waste to produce biogas was promising method to mitigate environmental problem of university canteen waste. Furthermore, biogas could be used as alternative energy source to supply energy demand at the university. This implementation is simultaneous solution for both waste and energy problems to achieve green campus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canteen%20waste" title="canteen waste">canteen waste</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=university" title=" university"> university</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20campus" title=" green campus"> green campus</a> </p> <a href="https://publications.waset.org/abstracts/38746/biogas-production-from-university-canteen-waste-effect-of-organic-loading-rate-and-retention-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7475</span> The Effect of Microwave Radiation on Biogas Production Efficiency Using Different Plant Substrates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Zieli%C5%84ski">Marcin Zieliński</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20D%C4%99bowski"> Marcin Dębowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Miros%C5%82aw%20Krzemieniewski"> Mirosław Krzemieniewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the present work was to assess the impact of using electromagnetic microwave radiation as a means of stimulating the thermal conditions in anaerobic reactors on biomethanation efficiency of different plant substrates, as measured by the quantity and quality of the resultant biogas.

After subjecting different plant substrates to fermentation in the model fermentation chambers, the largest improvements in regard to biogas production efficiency and biogas quality were recorded in the series with corn silage and grass silage. In the first case, the quantity of methane produced in the microwave-stimulated technological system exceeded by 15.26% the quantities produced in reactors heated conventionally.

In the study a semi-continuous glass reactor, having a total capacity of 13 liters and having a working capacity of 10 liters, was placed in an incubator, and the temperature was tried to be held at 38 °C. At first, the reactor was operated by adding 5 liters of animal manure and water with a ratio of 1/1. By passing time, the production rate of the gas reduced intensively that on the fourth day there was no production of gas and the system stopped working. In this condition, the pH was adjusted and by adding NaOH, it was increased from 5.4 to 7. On 48th day, the first gas measurement was done and an amount of 12.07 % of CH₄ was detected. After making buffer in the ambient, the number of bacteria existing in the cattle’s manure and contributing to the gas production was thought to be not adequate, and up to 20 % of its volume 2 liters of mud was added to the reactor. 7 days after adding the anaerobic mud, second gas measurement was carried out, and biogas including 43 % CH₄ was obtained. From the 61st day of the study, the cheese whey with the animal manure was started to be added with an amount of 40 mL per day. However, by passing time, the raising of the microorganisms existed in the whey (especially Ni and Co), the percent of methane in the biogas decreased. In fact, 2 weeks after adding PAS, the gas measurement was done and 36,97 % CH₄ was detected. 0,06 mL Ni-Co (to gain a concentration of 0.05 mg/L in the reactor’s mixture) solution was added to the system for 15 days. To find out the effect of the solution on archaea, 7 days after stopping addition of the solution, methane gas was found to have a 9,03 % increase and reach 46 %. Lastly, the effects of adding molasses to the reactor were investigated. The effects of its activity on the bacteria was analysed by adding 4 grams of it to the system. After adding molasses in 10 days, according to the last measurement, the amount of methane gas reached up to 49%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=cheese%20whey" title=" cheese whey"> cheese whey</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle%20manure" title=" cattle manure"> cattle manure</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/87784/investigation-of-the-effects-of-the-whey-addition-on-the-biogas-production-of-a-reactor-using-cattle-manure-for-biogas-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87784.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">334</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7473</span> Biogas as a Renewable Energy Fuel: A Review of Biogas Upgrading, Utilization and Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imran%20Ullah%20Khana">Imran Ullah Khana</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Hafiz%20Dzarfan%20Othmanb"> Mohd Hafiz Dzarfan Othmanb</a>, <a href="https://publications.waset.org/abstracts/search?q=Haslenda%20Hashima"> Haslenda Hashima</a>, <a href="https://publications.waset.org/abstracts/search?q=Takeshi%20Matsuurad"> Takeshi Matsuurad</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20F.%20Ismailb"> A.

The production of biomethane provides a versatile application in both heat and power generation and as a vehicular fuel. This paper systematically reviews the state of the art of biogas upgrading technologies with upgrading efficiency, methane (CH4) loss, environmental effect, development and commercialization, and challenges in terms of energy consumption and economic assessment. The market situation for biogas upgrading has changed rapidly in recent years, giving membrane separation a significant market share with traditional biogas upgrading technologies. In addition, the potential utilization of biogas, efficient conversion into bio-compressed natural gas (bio-CNG), and storage systems are investigated in depth. Two storing systems for bio-CNG at filling stations, namely buffer and cascade storage systems are used. The best storage system should be selected on the basis of the advantages of both systems. Also, the fuel economy and mass emissions for bio-CNG and CNG-filled vehicles are studied. There is the same fuel economy and less carbon dioxide (CO2) emission for bio-CNG. Based on the results of comparisons between the technical features of upgrading technologies, various specific requirements for biogas utilization and the relevant investment, and operating and maintenance costs, future recommendations are made for biogas upgrading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas%20upgrading" title="biogas upgrading">biogas upgrading</a>, <a href="https://publications.waset.org/abstracts/search?q=cost" title=" cost"> cost</a>, <a href="https://publications.waset.org/abstracts/search?q=utilization" title=" utilization"> utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-CNG" title=" bio-CNG"> bio-CNG</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/184961/biogas-as-a-renewable-energy-fuel-a-review-of-biogas-upgrading-utilization-and-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184961.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">50</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7472</span> Resource Assessment of Animal Dung for Power Generation: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gagandeep%20Kaur">Gagandeep Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Yadwinder%20Singh%20Brar"> Yadwinder Singh Brar</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20P.%20Kothari"> D.

Synthetic zeolites, commonly used for biogas upgrading, are characterized by excellent performance in terms of carbon dioxide adsorption, however, cost and environmental footprint represent a negative contribute to their sustainability. Natural zeolites contained in Tuff, a totally inexpensive byproduct of the construction industry, show very interesting selective adsorption properties, associated with its availability in regions, as central Italy, where biogas production from small scale plants is rapidly increasing. An in-house experimental device was assembled to measure the adsorption capacity of Tuff as a function of partial CO2 pressure for different temperatures (i.e. adsorption isotherms). Results show performances as high as 66% with respect to commercial zeolites (13X). A sensitivity analysis of different regeneration processes is also presented. A comparative analysis of natural and synthetic zeolites was finally performed using biogas samples obtained from different types of feedstock and characterized by varying CO2 and H2S content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas%20upgrading" title="biogas upgrading">biogas upgrading</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20adsorption" title=" CO2 adsorption"> CO2 adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20energy" title=" sustainable energy"> sustainable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=tuff" title=" tuff"> tuff</a> </p> <a href="https://publications.waset.org/abstracts/56266/sustainable-biogas-upgrading-characterization-of-adsorption-properties-of-tuff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56266.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7470</span> The Importance of Storage Period on Biogas Potential of Cattle Manure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seongwon%20Im">Seongwon Im</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimin%20Kim"> Jimin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyeongcheol%20Kim"> Kyeongcheol Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Hoon%20Kim"> Dong-Hoon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cattle manure (CM) produced from farmhas been utilized to soils for increasing crop production owing to high nutrients content and effective microorganisms. Some cities with the concentrated activity of livestock industry have suffered from environmental problems, such as odorous gas emissions and soil and water pollution, caused by excessive use of compost. As an alternative option, the anaerobic digestion (AD) process can be utilized, which can reduce the volume of organic waste but also produce energy. According to Korea-Ministry of Trade, Industry, and Energy (KMTIE), the energy potential of CM via biogas production was estimated to be 0.8 million TOE per year, which is higher than that of other organic wastes. However, limited energy is recovered since useful organic matter, capable of converting to biogas, may be degraded during the long storage period (1-6 months).In this study, the effect of storage period on biogas potential of CM was investigated. Compared to fresh CM (VS 14±1 g/L, COD 205±5 g/L, TKN 7.4±0.8 g/L, NH4+-N 1.5±0.1), old CM has higher organic (35-37%) and nitrogen content (50-100%) due to the drying process during storage. After stabilization period, biogas potential of 0.09 L CH4/g VS was obtained in R1 (old CM supplement) at HRT of 150-100 d, and it was decreased further to 0.06 L CH4/g VS at HRT of 80 d. The drop of pH and organic acids accumulation were not observed during the whole operation of R1. Ammonia stripping and pretreatment of CM were found to be not effective to increase CH4 yield. On the other hand, a sudden increase of biogas potential to 0.19-0.22 L CH4/g VS was achieved in R2 after changing feedstock to fresh CM. The expected reason for the low biogas potential of old CM might be related with the composition of organic matters in CM. Easily biodegradable organic matters in the fresh CM were contained in high concentration, butthey were removed by microorganisms during storing CM in a farm, resulting low biogas yield. This study implies that fresh storage is important to make AD process applicable for CM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=storage%20period" title="storage period">storage period</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle%20manure" title=" cattle manure"> cattle manure</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas%20potential" title=" biogas potential"> biogas potential</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20analysis" title=" microbial analysis"> microbial analysis</a> </p> <a href="https://publications.waset.org/abstracts/143492/the-importance-of-storage-period-on-biogas-potential-of-cattle-manure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143492.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7469</span> Analysis of the Impact and Effectiveness of Government Funded Small-Scale Biogas Projects in Giyani Municipality, Limpopo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lindiwe%20Ngcobo">Lindiwe Ngcobo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study is to describe and understand the benefits and costs of having biogas digesters at both household and society level. On a household level, the purpose is to understand how rural households benefit from the biogas digesters, for example, by converting animal and human waste through biogas digesters, and at what costs the benefits are realized. At a societal level, the purpose is to understand the costs and benefits of biogas digesters relative to the situation of rural communities who do not have flush toilets and have no appropriate waste disposal services while they incur electricity costs. Multiple regression analysis was used to determine the effect of biogas digesters on electricity availability and waste management. The results showed that beneficiaries spent less on electricity using household waste, and also waste disposal costs were eliminated from household expenses. A move to biogas energy production can be beneficial to rural households. It is economically and environmentally friendly. Small-scale farmers need to be introduced to agricultural innovations that can assist them in producing nutritious crops at a low cost. This can be a good opportunity to start an agribusiness that focuses on organic crops. Extensions and training institutions have to play a part in supporting households to develop entrepreneurial skills. Cost-benefit analysis showed that the benefits of biogas exceed the costs of the biogas projects. This implies that this technology should be promoted in rural households. Government financial incentives must be put in place to motivate a generation of organic Agri-prenuers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agri-prenuers" title="Agri-prenuers">Agri-prenuers</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas%20digester" title=" biogas digester"> biogas digester</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas%20energy" title=" biogas energy"> biogas energy</a>, <a href="https://publications.waset.org/abstracts/search?q=disposal%20costs" title=" disposal costs"> disposal costs</a> </p> <a href="https://publications.waset.org/abstracts/120223/analysis-of-the-impact-and-effectiveness-of-government-funded-small-scale-biogas-projects-in-giyani-municipality-limpopo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7468</span> Effect of the Magnetite Nanoparticles Concentration on Biogas and Methane Production from Chicken Litter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guadalupe%20Stefanny%20Aguilar-Moreno">Guadalupe Stefanny Aguilar-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Angel%20Aguilar-Mendez"> Miguel Angel Aguilar-Mendez</a>, <a href="https://publications.waset.org/abstracts/search?q=Teodoro%20Espinosa-Solares"> Teodoro Espinosa-Solares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the agricultural sector, one of the main emitters of greenhouse gases is manure management, which has been increased considerably in recent years. Biogas is an energy source that can be produced from different organic materials through anaerobic digestion (AD); however, production efficiency is still low. Several techniques have been studied to increase its performance, such as co-digestion, the variation of digestion conditions, and nanomaterials used. Therefore, the aim of this investigation was to evaluate the effect of magnetite nanoparticles (NPs) concentration, synthesized by co-precipitation, on the biogas and methane production in AD using chicken litter as a substrate. Synthesis of NPs was performed according to the co-precipitation method, for which a fractional factorial experimental design 25⁻² with two replications was used. The study factors were concentrations (precursors and passivating), time of sonication and dissolution temperatures, and the response variables were size, hydrodynamic diameter (HD) and zeta potential. Subsequently, the treatment that presented the smallest NPs was chosen for their use on AD. The AD was established in serological bottles with a working volume of 250 mL, incubated at 36 ± 1 °C for 80 days. The treatments consisted of the addition of different concentrations of NPs in the microcosms: chicken litter only (control), 20 mg∙L⁻¹ of NPs + chicken litter, 40 mg∙L⁻¹ of NPs + chicken litter and 60 mg∙L⁻¹ of NPs + chicken litter, all by triplicate. Methane and biogas production were evaluated daily. The smallest HD (49.5 nm) and the most stable NPs (21.22 mV) were obtained with the highest passivating concentration and the lower precursors dissolution temperature, which were the only factors that had a significant effect on the HD. In the transmission electron microscopy performed to these NPs, an average size of 4.2 ± 0.73 nm was observed. The highest biogas and methane production was obtained with the treatment that had 20 mg∙L⁻¹ of NPs, being 29.5 and 73.9%, respectively, higher than the control, while the treatment with the highest concentration of NPs was not statistically different from the control. From the above, it can be concluded that the magnetite NPs promote the biogas and methane production in AD; however, high concentrations may cause inhibitory effects among methanogenic microorganisms.
