By waste elimination, the lead time is reduced significantly and lean manufacturing provides companies with an important privilege under today's competitive conditions. The initial point of lean thinking is the value. This notion create of a specific product with specific properties for which the customer is ready to pay and which satisfies his needs within a specific time frame and at a specific price. Considering this, the final customer determines the value but the manufacturer creates this value of the product. The value stream is the whole set of activities required for each product. These activities may or may not be essential for the value. Through value stream mapping, all employees can see the sources of waste and develop future cases to eliminate it. This study focused on manufacturing to eliminate the waste which created a cost but did not create any value. The study was carried out at the Department of Assembly/Logistics at Toyota Motor Manufacturing Turkey from the automotive industry with a high product mix and variable demands. As a result of the value stream analysis, improvements are planned for the future cases. The process was improved by applying these suggestions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lead%20time" title="lead time">lead time</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20improvement" title=" performance improvement"> performance improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20stream%20papping" title=" value stream papping"> value stream papping</a> </p> <a href="https://publications.waset.org/abstracts/49451/the-lean-manufacturing-practices-in-an-automotive-company-using-value-stream-mapping-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49451.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">311</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">3296</span> Strategies for E-Waste Management: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linh%20Thi%20Truc%20Doan">Linh Thi Truc Doan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Amer"> Yousef Amer</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Heon%20Lee"> Sang-Heon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Phan%20Nguyen%20Ky%20Phuc"> Phan Nguyen Ky Phuc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last few decades, with the high-speed upgrade of electronic products, electronic waste (e-waste) has become one of the fastest growing wastes of the waste stream. In this context, more efforts and concerns have already been placed on the treatment and management of this waste. To mitigate their negative influences on the environment and society, it is necessary to establish appropriate strategies for e-waste management. Hence, this paper aims to review and analysis some useful strategies which have been applied in several countries to handle e-waste. Future perspectives on e-waste management are also suggested. The key findings found that, to manage e-waste successfully, it is necessary to establish effective reverse supply chains for e-waste, and raise public awareness towards the detrimental impacts of e-waste. The result of the research provides valuable insights to governments, policymakers in establishing e-waste management in a safe and sustainable manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-waste" title="e-waste">e-waste</a>, <a href="https://publications.waset.org/abstracts/search?q=e-waste%20management" title=" e-waste management"> e-waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20regulations" title=" recycling regulations"> recycling regulations</a> </p> <a href="https://publications.waset.org/abstracts/103633/strategies-for-e-waste-management-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103633.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">275</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">3295</span> Urgent Need for E -Waste Management in Mongolia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enkhjargal%20Bat-Ochir">Enkhjargal Bat-Ochir </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global market of electrical and electronic equipment (EEE) has increasing rapidly while the lifespan of these products has become increasingly shorter.

Water quality of Antalya Basin was determined according to Biological Monitoring Working Party (BMWP) system, by using macrozoobenthic invertebrates and physicochemical parameters. As a result of the evaluation, while Aksu Stream was determined as the most polluted stream in Antalya Basin, Isparta Stream was determined as the most polluted tributary of Aksu Stream. Pollution level of the Isparta Stream was determined as quality class V and it is the extremely polluted part of stream. Pollution loads at the sources of the streams were determined in low levels in general. Due to some parts of the streams have passed through deep canyons and take their sources from nonresidential and non-arable regions, majority of the streams that take place in Antalya Basin are at high quality level. Waste water, which comes from agricultural and residential regions, affects the lower basins of the streams. Because of the waste water, lower parts of the stream basins exposed to the pollution under anthropogenic effects. However, in Aksu Stream, which differs by being exposed to domestic and industrial wastes of Isparta City, extreme pollution was determined, particularly in the Isparta Stream part. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antalya%20basin" title="Antalya basin">Antalya basin</a>, <a href="https://publications.waset.org/abstracts/search?q=biomonitoring" title=" biomonitoring"> biomonitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=BMWP" title=" BMWP"> BMWP</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/49348/water-quality-determination-of-river-systems-in-antalya-basin-by-biomonitoring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49348.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">323</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">3293</span> Analysis of Solid Waste Management Practices and the Implications for Human Health and the Environment: A Case Study of Kayamandi Informal Settlement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20Iyobosa%20Asemota">Peter Iyobosa Asemota</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study on solid waste management practices addressed aspects of environmental and health impacts resulting from poor management of solid waste. The study was occasioned by the observed rate and volume of illegal and indiscriminate dumping of solid waste materials especially in informal settlements. The main focus of this study was to establish the impact of waste management practices on human health and the environment. The study, therefore, presents a critical analysis of the state of solid waste management in the study area and the implications for human health and the environment. The study was carried out in Kayamandi informal settlement within Stellenbosch municipality. The sustainable management of solid waste is very important in order to minimize the environmental and public health risks associated with improper solid waste management. There is no denying the fact that the problems of waste management will become critical as time goes on because of improper and inefficient waste management practices. Towns and cities exhibit the burdens of waste management which is a characteristics feature of most African cities. The study critically assess the implementation of waste management practices by the residents of the informal settlement; identify the factors affecting management issues in the operation of solid waste management system by the municipality; identify factors militating against the implementation of waste management policies and legislation. Furthermore, a waste assessment study was carried out to assess the generation; composition of the waste stream and also determine the attitudes and behavior of the residents with regard to waste management practices. Findings from the study revealed that Kayamandi is not different from other informal settlements with regards to waste management. People are of the opinion that solid waste management is the sole responsibility of municipal authorities and as such, the government should be responsible for bearing the cost of solid waste management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=waste" title=" waste"> waste</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20composition" title=" waste composition"> waste composition</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20stream" title=" waste stream"> waste stream</a>, <a href="https://publications.waset.org/abstracts/search?q=policy" title=" policy"> policy</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20categories" title=" waste categories"> waste categories</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitary%20landfill" title=" sanitary landfill"> sanitary landfill</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20collection" title=" waste collection"> waste collection</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20solid%20waste%20management" title=" integrated solid waste management "> integrated solid waste management </a> </p> <a href="https://publications.waset.org/abstracts/20014/analysis-of-solid-waste-management-practices-and-the-implications-for-human-health-and-the-environment-a-case-study-of-kayamandi-informal-settlement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20014.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">696</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">3292</span> Lean Manufacturing Implementation in Fused Plastic Bags Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tareq%20Issa">Tareq Issa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lean manufacturing is concerned with the implementation of several tools and methodologies that aim for the continuous elimination of wastes throughout manufacturing process flow in the production system. This research addresses the implementation of lean principles and tools in a small-medium industry focusing on 'fused' plastic bags production company in Amman, Jordan. In this production operation, the major type of waste to eliminate include material, waiting-transportation, and setup wastes. The primary goal is to identify and implement selected lean strategies to eliminate waste in the manufacturing process flow. A systematic approach was used for the implementation of lean principles and techniques, through the application of Value Stream Mapping analysis. The current state value stream map was constructed to improve the plastic bags manufacturing process through identifying opportunities to eliminate waste and its sources. Also, the future-state value stream map was developed describing improvements in the overall manufacturing process resulting from eliminating wastes. The implementation of VSM, 5S, Kanban, Kaizen, and Reduced lot size methods have provided significant benefits and results. Productivity has increased to 95.4%, delivery schedule attained at 99-100%, reduction in total inventory to 1.4 days and the setup time for the melting process was reduced to about 30 minutes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lean%20implementation" title="lean implementation">lean implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20bags%20industry" title=" plastic bags industry"> plastic bags industry</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20stream%20map" title=" value stream map"> value stream map</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20flow" title=" process flow"> process flow</a> </p> <a href="https://publications.waset.org/abstracts/91127/lean-manufacturing-implementation-in-fused-plastic-bags-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91127.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">175</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">3291</span> Determination of Flow Arrangement for Optimum Performance in Heat Exchangers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Salisu%20Atiku">Ahmed Salisu Atiku</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This task involves the determination of the flow arrangement for optimum performance and the calculation of total heat transfer of two identical double pipe heat exchangers in series. The inner pipe contains the cold water stream at 27°C, whilst the outer pipe contains the two hot stream of water at 50°C and 90 °C which can be mixed in any way desired. The analysis was carried out using counter flow arrangement due to its good heat transfer ability. The best way of heating this cold stream was found out to be passing the 90°C hot stream through the two heat exchangers. The outlet temperature of the cold stream was found to be 39.6°C and overall heat transfer of 131.3 kW. Though starting with 50°C hot stream in the first heat exchanger followed by 90°C hot stream in the second heat exchanger gives an outlet temperature almost the same as 90°C hot stream alone, but the heat transfer is low. The reason for the low heat transfer was that only the heat transfer in the second heat exchanger is considered. Whilst the reason behind high outlet temperature was that the cold stream was already preheated by the first stream. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20stream" title="cold stream">cold stream</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20arrangement" title=" flow arrangement"> flow arrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger" title=" heat exchanger"> heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20stream" title=" hot stream"> hot stream</a> </p> <a href="https://publications.waset.org/abstracts/51973/determination-of-flow-arrangement-for-optimum-performance-in-heat-exchangers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51973.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">323</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">3290</span> Municipal Solid Waste (MSW) Composition and Generation in Nablus City, Palestine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Issam%20A.%20Al-Khatib">Issam A. Al-Khatib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to achieve a significant reduction of waste amount flowing into landfills, it is important to first understand the composition of the solid municipal waste generated. Hence a detailed analysis of municipal solid waste composition has been conducted in Nablus city. The aim is to provide data on the potential recyclable fractions in the actual waste stream, with a focus on the plastic fraction. Hence, waste-sorting campaigns were conducted on mixed waste containers from five districts in Nablus city. The districts vary in terms of infrastructure and average income. The target is to obtain representative data about the potential quantity and quality of household plastic waste. The study has measured the composition of municipal solid waste collected/ transported by Nablus municipality. The analysis was done by categorizing the samples into eight primary fractions (organic and food waste, paper and cardboard, glass, metals, textiles, plastic, a fine fraction (<10 mm), and others). The study results reveal that the MSW stream in Nablus city has a significant bio- and organic waste fraction (about 68% of the total MSW). The second largest fraction is paper and cardboard (13.6%), followed by plastics (10.1%), textiles (3.2%), glass (1.9%), metals (1.8%), a fine fraction (0.5%), and other waste (0.3%). After this complete and detailed characterization of MSW collected in Nablus and taking into account the content of biodegradable organic matter, the composting could be a solution for the city of Nablus where the surrounding areas of Nablus city have agricultural activities and could be a natural outlet to the compost product. Different waste management options could be practiced in the future in addition to composting, such as energy recovery and recycling, which result in a greater possibility of reducing substantial amounts that are disposed of at landfills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developing%20countries" title="developing countries">developing countries</a>, <a href="https://publications.waset.org/abstracts/search?q=composition" title=" composition"> composition</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=recyclable" title=" recyclable"> recyclable</a>, <a href="https://publications.waset.org/abstracts/search?q=waste." title=" waste."> waste.</a> </p> <a href="https://publications.waset.org/abstracts/162206/municipal-solid-waste-msw-composition-and-generation-in-nablus-city-palestine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162206.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">90</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">3289</span> Non-Burn Treatment of Health Care Risk Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jefrey%20Pilusa">Jefrey Pilusa</a>, <a href="https://publications.waset.org/abstracts/search?q=Tumisang%20Seodigeng"> Tumisang Seodigeng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research discusses a South African case study for the potential of utilizing refuse-derived fuel (RDF) obtained from non-burn treatment of health care risk waste (HCRW) as potential feedstock for green energy production. This specific waste stream can be destroyed via non-burn treatment technology involving high-speed mechanical shredding followed by steam or chemical injection to disinfect the final product. The RDF obtained from this process is characterised by a low moisture, low ash, and high calorific value which means it can be potentially used as high-value solid fuel. Due to the raw feed of this RDF being classified as hazardous, the final RDF has been reported to be non-infectious and can blend with other combustible wastes such as rubber and plastic for waste to energy applications. This study evaluated non-burn treatment technology as a possible solution for on-site destruction of HCRW in South African private and public health care centres. Waste generation quantities were estimated based on the number of registered patient beds, theoretical bed occupancy. Time and motion study was conducted to evaluate the logistics viability of on-site treatment. Non-burn treatment technology for HCRW is a promising option for South Africa, and successful implementation of this method depends upon the initial capital investment, operational cost and environmental permitting of such technology; there are other influencing factors such as the size of the waste stream, product off-take price as well as product demand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autoclave" title="autoclave">autoclave</a>, <a href="https://publications.waset.org/abstracts/search?q=disposal" title=" disposal"> disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel" title=" fuel"> fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=incineration" title=" incineration"> incineration</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20waste" title=" medical waste"> medical waste</a> </p> <a href="https://publications.waset.org/abstracts/75768/non-burn-treatment-of-health-care-risk-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75768.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">177</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">3288</span> Innovative Method for Treating Oil-Produced Water with Low Operating Cost</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Salman">Maha Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Gada%20Al-Nuwaibit"> Gada Al-Nuwaibit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al-Haji"> Ahmed Al-Haji</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleh%20Al-Haddad"> Saleh Al-Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Al-Mesri"> Abbas Al-Mesri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansour%20Al-Rugeeb"> Mansour Al-Rugeeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The high salinity of oil-produced water and its complicated chemical composition, makes designing a suitable treatment system for oil-produced water is extremely difficult and costly.

The proposal will investigate the scaling potential of oil-produce water, seawater and the selected brine water (BW) produced from Sulaibiya waste water treatment and reclamation plant (SWWTRP) before and after the mixing with oil-produced water, and will calculate the scaling potential of all expected precipitated salts using different conversion and different % of mixing to optimize the % of mixing between the oil-produced water and the selected stream.

The results include mean and turbulent velocities and quantify the large effects of the coflow stream on an impinging air jet. The study of the jet in a no-directed coflow stream shows the presence of a phenomenon of recirculation near the flat plate. The influence of the coflow velocity ratio on the behavior of an impinging plane jet was also numerically investigated.

Average food type compositions were 39% rice, 6% meat, 34% fruits and vegetables, and 23% bread. Methane yield was also measured for all food types and was found to be 362, 499, 352, and 375 mL/g VS for rice, meat, fruits and vegetables, and bread, respectively. A representative food waste sample was created to test the actual methane yield and compare it to calculated one. Actual methane yield (414 mL/g VS) was greater than the calculated value (377 mL/g VS) based on food type proportions and their specific methane yield. This study emphasizes the effect of the types of food and their proportions in food waste on the final biogas production. Findings in this study provide representative methane emission factors for Irbid’s food waste, which represent as high as 68% of total Municipal Solid Waste (MSW) in Irbid, and also indicate the energy and economic value within the solid waste stream in Irbid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title="food waste">food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste%20management" title=" solid waste management"> solid waste management</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=methane%20yield" title=" methane yield"> methane yield</a> </p> <a href="https://publications.waset.org/abstracts/84663/analyzing-irbids-food-waste-as-feedstock-for-anaerobic-digestion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84663.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">204</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">3285</span> Application of Microbially Induced Calcite Precipitation Technology in Construction Materials: A Comprehensive Review of Waste Stream Contributions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Sina%20Fouladi">Amir Sina Fouladi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arul%20Arulrajah"> Arul Arulrajah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Chu"> Jian Chu</a>, <a href="https://publications.waset.org/abstracts/search?q=Suksun%20Horpibulsuk"> Suksun Horpibulsuk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Waste generation is a growing concern in many countries across the world, particularly in urban areas with high rates of population growth and industrialization. The increasing amount of waste generated from human activities has led to environmental, economic, and health issues. Improper disposal of waste can result in air and water pollution, land degradation, and the spread of diseases. Waste generation also consumes large amounts of natural resources and energy, leading to the depletion of valuable resources and contributing to greenhouse gas emissions. To address these concerns, there is a need for sustainable waste management practices that reduce waste generation and promote resource recovery and recycling. Amongst these, developing innovative technologies such as Microbially Induced Calcite Precipitation (MICP) in construction materials is an effective approach to transforming waste into valuable and sustainable applications. MICP is an environmentally friendly microbial-chemical technology that applies microorganisms and chemical reagents to biological processes to produce carbonate mineral. This substance can be an energy-efficient, cost-effective, sustainable solution to environmental and engineering challenges. Recent research has shown that waste streams can replace several MICP-chemical components in the cultivation media of microorganisms and cementation reagents (calcium sources and urea). In addition to its effectiveness in treating hazardous waste streams, MICP has been found to be cost-effective and sustainable solution applicable to various waste media. This comprehensive review paper aims to provide a thorough understanding of the environmental advantages and engineering applications of MICP technology, with a focus on the contribution of waste streams. It also provides researchers with guidance on how to identify and overcome the challenges that may arise applying the MICP technology using waste streams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20stream" title="waste stream">waste stream</a>, <a href="https://publications.waset.org/abstracts/search?q=microbially%20induced%20calcite%20precipitation" title=" microbially induced calcite precipitation"> microbially induced calcite precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20materials" title=" construction materials"> construction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/168089/application-of-microbially-induced-calcite-precipitation-technology-in-construction-materials-a-comprehensive-review-of-waste-stream-contributions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168089.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">79</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">3284</span> Optimization of Lean Methodologies in the Textile Industry Using Design of Experiments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Yame">Ahmad Yame</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahad%20Ali"> Ahad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Badih%20Jawad"> Badih Jawad</a>, <a href="https://publications.waset.org/abstracts/search?q=Daw%20Al-Werfalli%20Mohamed%20Nasser"> Daw Al-Werfalli Mohamed Nasser</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabah%20Abro"> Sabah Abro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Industries in general have a lot of waste.

It is also a major way for wasting such an energy that could be better utilized and even generates revenue. Minimize flaring is an effective approach for reducing GHG emissions and also conserving energy in flaring systems. Integrating waste and flared gases into the fuel gas networks (FGN) of refineries is an efficient tool. A fuel gas network collects fuel gases from various source streams and mixes them in an optimal manner, and supplies them to different fuel sinks such as furnaces, boilers, turbines, etc. In this article we use fuel gas network model proposed by Hasan et al. as a base model and modify some of its features and add constraints on emission pollution by gas flaring to reduce GHG emissions as possible. Results for a refinery case study showed that integration of flare gas stream with waste and natural gas streams to construct an optimal FGN can significantly reduce total annualized cost and flaring emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flaring" title="flaring">flaring</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20gas%20network" title=" fuel gas network"> fuel gas network</a>, <a href="https://publications.waset.org/abstracts/search?q=GHG%20emissions" title=" GHG emissions"> GHG emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=stream" title=" stream "> stream </a> </p> <a href="https://publications.waset.org/abstracts/13259/reducing-energy-consumption-and-ghg-emission-by-integration-of-flare-gas-with-fuel-gas-network-in-refinery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13259.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">344</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">3282</span> The Impact of Mining Activities on the Surface Water Quality: A Case Study of the Kaap River in Barberton, Mpumalanga</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20F.%20Mamabolo">M.

Waste materials generated from gold mining and processing have severe and widespread impacts on water resources. Therefore, a total of 30 water samples were collected from Fig Tree Creek, Kaapriver, Sheba mine stream & Sauid kaap river to investigate the impact of gold mines on the Kaap River system. Physicochemical parameters (pH, EC and TDS) were taken using a BANTE 900P portable water quality meter. The concentration of Fe, Cu, Co, and SO₄²⁻ in water samples were analysed using Inductively Coupled Plasma-Mass spectrophotometry (ICP-MS) at 0.01 mg/L. The results were compared to the regulatory guideline of the World Health Organization (WHO) and the South Africa National Standards (SANS). It was found that Fe, Cu and Co were below the guideline values while SO₄²⁻ detected in Sheba mine stream exceeded the 250 mg/L limit for both seasons, attributed by mine wastewater. SO₄²⁻ was higher in wet season due to high evaporation rates and greater interaction between rocks and water. The pH of all the streams was within the limit (≥5 to ≤9.7), however EC of the Sheba mine stream, Suid Kaap River & where the tributary connects with the Fig Tree Creek exceeded 1700 uS/m, due to dissolved material. The TDS of Sheba mine stream exceeded 1000 mg/L, attributed by high SO₄²⁻ concentration. While the tributary connecting to the Fig Tree Creek exceed the value due to pollution from household waste, runoff from agriculture etc. In conclusion, the water from all sampled streams were safe for consumption due to low concentrations of physicochemical parameters. However, elevated concentration of SO₄²⁻ should be monitored and managed to avoid water quality deterioration in the Kaap River system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaap%20river%20system" title="Kaap river system">Kaap river system</a>, <a href="https://publications.waset.org/abstracts/search?q=mines" title=" mines"> mines</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphate" title=" sulphate"> sulphate</a> </p> <a href="https://publications.waset.org/abstracts/173969/the-impact-of-mining-activities-on-the-surface-water-quality-a-case-study-of-the-kaap-river-in-barberton-mpumalanga" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173969.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">81</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">3281</span> Waste Identification Diagrams Effectiveness: A Case Study in the Manaus Industrial Pole</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Dinis-Carvalho">José Dinis-Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Levi%20Guimar%C3%A3es"> Levi Guimarães</a>, <a href="https://publications.waset.org/abstracts/search?q=Celina%20Le%C3%A3o"> Celina Leão</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20Sousa"> Rui Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Eliza%20Vieira"> Rosa Eliza Vieira</a>, <a href="https://publications.waset.org/abstracts/search?q=Larissa%20Thomaz"> Larissa Thomaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelliane%20Guerreiro"> Kelliane Guerreiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper investigates the efficacy of waste identification diagrams (WIDs) as a tool for waste reduction and management within the Manaus Industrial Pole.

A value stream is an assortment of all actions (value added as well as non-value added) that are required to bring a product through the essential flows, starting with raw material and ending with the customer. For drawing current state value stream mapping, all relevant data of the receipt cycle has been collected and analyzed. Then analysis of current state map has been done for determining the type and quantum of waste at every stage which helped in ascertaining as to how far the warehouse is from the concept of lean manufacturing. From the results achieved by current VSM, it was observed that the two processes- Preparation of GRN (Goods Receipt Number) and Preparation of UD (Usage Decision) are both bottle neck operations and have higher cycle time. This root cause analysis of various types of waste helped in designing a strategy for step-wise implementation of lean tools. The future state thus created a lean flow of materials at the warehouse center, reducing the lead time of the receipt cycle from 11 days to 7 days and increasing overall efficiency by 27.27%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=current%20VSM" title="current VSM">current VSM</a>, <a href="https://publications.waset.org/abstracts/search?q=ECRS" title=" ECRS"> ECRS</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20VSM" title=" future VSM"> future VSM</a>, <a href="https://publications.waset.org/abstracts/search?q=receipt%20cycle" title=" receipt cycle"> receipt cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=VSM" title=" VSM"> VSM</a> </p> <a href="https://publications.waset.org/abstracts/61822/implementation-of-lean-tools-value-stream-mapping-and-ecrs-in-an-oil-refinery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61822.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">315</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">3279</span> Quantification of Hydrogen Sulfide and Methyl Mercaptan in Air Samples from a Waste Management Facilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20F.%20Vieira">R.

In this context having a quantifying method for these compounds helps in the optimization of treatment with the goal of their elimination, namely biofiltration processes. The aim of this study was the development of a method for quantification of odorous gases in waste treatment plants air samples. A method based on head space solid phase microextraction (HS-SPME) coupled with gas chromatography - flame photometric detector (GC-FPD) was used to analyse H2S and Metil Mercaptan (MM). The extraction was carried out with a 75-μm Carboxen-polydimethylsiloxane fiber coating at 22 ºC for 20 min, and analysed by a GC 2010 Plus A from Shimadzu with a sulphur filter detector: splitless mode (0.3 min), the column temperature program was from 60 ºC, increased by 15 ºC/min to 100 ºC (2 min). The injector temperature was held at 250 ºC, and the detector at 260 ºC. For calibration curve a gas diluter equipment (digital Hovagas G2 - Multi Component Gas Mixer) was used to do the standards. This unit had two input connections, one for a stream of the dilute gas and another for a stream of nitrogen and an output connected to a glass bulb. A 40 ppm H2S and a 50 ppm MM cylinders were used. The equipment was programmed to the selected concentration, and it automatically carried out the dilution to the glass bulb. The mixture was left flowing through the glass bulb for 5 min and then the extremities were closed. This method allowed the calibration between 1-20 ppm for H2S and 0.02-0.1 ppm and 1-3.5 ppm for MM. Several quantifications of air samples from inlet and outlet of a biofilter operating in a waste management facility in the north of Portugal allowed the evaluation the biofilters performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofiltration" title="biofiltration">biofiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20sulphide" title=" hydrogen sulphide"> hydrogen sulphide</a>, <a href="https://publications.waset.org/abstracts/search?q=mercaptans" title=" mercaptans"> mercaptans</a>, <a href="https://publications.waset.org/abstracts/search?q=quantification" title=" quantification"> quantification</a> </p> <a href="https://publications.waset.org/abstracts/26726/quantification-of-hydrogen-sulfide-and-methyl-mercaptan-in-air-samples-from-a-waste-management-facilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26726.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">476</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">3278</span> Waste Management in Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20Ekene%20Egwu">Peter Ekene Egwu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Waste management is of critical importance in Africa for reasons related to public health, human dignity, climate resilience and environmental preservation.

We allocated 32 free-grazing lambs to four groups and provided each with water from a different source (upper stream, lower stream, well, and pond) for 49 days. We recorded the amount of water consumed by the lambs, as well as their body weight, behavior, white blood cell count, acute phase (haptoglobin) protein level, and fecal condition. We measured the chemical and biological qualities of the four types of water, and we detected enteropathogenic and enterohemorrhagic Escherichia coli in fecal samples by using a genetic approach. Pond water contained high levels of nitrogen and minerals, and well water contained high levels of bacteria. The odor concentration index decreased in order from pond water to upper stream, lower stream, and well. On day 15 of the experiment, the following parameters were the highest in lambs drinking water from the following sources: water intake (pond or lower stream), body weight gain (pond), WBC count (lower stream), haptoglobin concentration (well), and enteropathogenic E. coli infection rate (lower stream). Lambs that drank well water spent more time lying down and less time grazing than the others, and lambs that drank pond water spent more time standing and less time lying down. Lambs given upper or lower stream water exhibited more severe diarrhea on day 15 of the experiment than before the experiment. Mongolian sheep seemed to adapt to chemically contaminated water: their productivity benefited the most from pond water, likely owing to its rich mineral content. Lambs that drank lower stream water showed increases in enteropathogenic E. coli infection, clinical diarrhea, and WBC count. Lambs that drank well water, which was bacteriologically contaminated, had increased serum acute phase protein levels and poor physical condition; they were thus at increased risk of negative health and production effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA" title="DNA">DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=Escherichia%20coli" title=" Escherichia coli"> Escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=fecal%20sample" title=" fecal sample"> fecal sample</a>, <a href="https://publications.waset.org/abstracts/search?q=lower%20stream" title=" lower stream"> lower stream</a>, <a href="https://publications.waset.org/abstracts/search?q=well%20water" title=" well water"> well water</a> </p> <a href="https://publications.waset.org/abstracts/33379/mongolian-water-quality-problem-and-health-of-free-grazing-sheep" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33379.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">472</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">3274</span> Assessment of Escherichia coli along Nakibiso Stream in Mbale Municipality, Uganda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Walusansa">Abdul Walusansa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to assess the level of microbial pollution along Nakibiso stream. The study was carried out in polluted waters of Nakibiso stream, originating from Mbale municipality and running through ADRA Estates to Namatala Wetlands in Eastern Uganda. Four sites along the stream were selected basing on the activities of their vicinity. A total of 120 samples were collected in sterile bottles from the four sampling locations of the stream during the wet and dry seasons of the year 2011. The samples were taken to the National water and Sewerage Cooperation Laboratory for Analysis. Membrane filter technique was used to test for Erischerichia coli. Nitrogen, Phosphorus, pH, dissolved oxygen, electrical conductivity, total suspended solids, turbidity and temperature were also measured. Results for Nitrogen and Phosphorus for sites; 1, 2, 3 and 4 were 1.8, 8.8, 7.7 and 13.8 NH4-N mg/L; and 1.8, 2.1, 1.8 and 2.3 PO4-P mg/L respectively. Basing on these results, it was estimated that farmers use 115 and 24 Kg/acre of Nitrogen and Phosphorus respectively per month. Taking results for Nitrogen, the same amount of Nutrients in artificial fertilizers would cost $ 88. This shows that reuse of wastewater has a potential in terms of nutrients. The results for E. coli for sites 1, 2, 3 and 4 were 1.1 X 107, 9.1 X 105, 7.4 X 105, and 3.4 X 105 respectively. E. coli hence decreased downstream with statistically significant variations between sites 1 and 4. Site 1 had the highest mean E.coli counts. The bacterial contamination was significantly higher during the dry season when more water was needed for irrigation. Although the water had the potential for reuse in farming, bacterial contamination during both seasons was higher than 103 FC/100ml recommended by WHO for unrestricted Agriculture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20coli" title="E. coli">E. coli</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen" title=" nitrogen"> nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorus" title=" phosphorus"> phosphorus</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20reuse" title=" water reuse"> water reuse</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water" title=" waste water"> waste water</a> </p> <a href="https://publications.waset.org/abstracts/68433/assessment-of-escherichia-coli-along-nakibiso-stream-in-mbale-municipality-uganda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68433.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">247</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">3273</span> Is there Anything Useful in That?

Much of the demographic changes up to 2075 will take place in the less developed regions. There are currently 54 countries which fall under the bracket of being defined as having ‘low-middle income’ economies and need new ways to generate valuable products from current resources that is available. Artemisia annua L is well used for the extraction of the phytochemical artemisinin, which accounts for around 0.01 to 1.4 % dry weight of the plant. Artemisinin is used in the treatment of malaria, a disease rampart in sub-Saharan Africa and in many other countries. Once artemisinin has been extracted the spent leaf and waste streams are disposed of as waste. A feasibility study was carried out looking at increasing the biomass value of A. annua, by designing a biorefinery where spent leaf and waste streams are utilized for high product generation. Quercetin, ferulic acid, dihydroartemisinic acid, artemisinic acid and artemsinin were screened for in the waste stream samples and the spent leaf. The analytical results showed that artemisinin, artemisinic acid and dihydroartemisinic acid were present in the waste extracts as well as camphor and arteannuin b. Ongoing effects are looking at using more industrially relevant solvents to extract the phytochemicals from the waste fractions and investigate how microwave pyrolysis of spent leaf can be utilized to generate bio-products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20value%20product%20generation" title="high value product generation">high value product generation</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatics" title=" bioinformatics"> bioinformatics</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedicine" title=" biomedicine"> biomedicine</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20streams" title=" waste streams"> waste streams</a>, <a href="https://publications.waset.org/abstracts/search?q=spent%20leaf" title=" spent leaf"> spent leaf</a> </p> <a href="https://publications.waset.org/abstracts/8551/is-there-anything-useful-in-that-high-value-product-extraction-from-artemisia-annua-l-in-the-spent-leaf-and-waste-streams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8551.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">349</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">3272</span> Modular Data and Calculation Framework for a Technology-based Mapping of the Manufacturing Process According to the Value Stream Management Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tim%20Wollert">Tim Wollert</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabian%20Behrendt"> Fabian Behrendt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Value Stream Management (VSM) is a widely used methodology in the context of Lean Management for improving end-to-end material and information flows from a supplier to a customer from a company’s perspective.

In addition, a lack of reliable waste data makes it even more difficult for designing and implementing an effective waste management plan. This article conceptualizes the opportunity to improve resource productivity by integrating smart resource tracking system (SRTS) into the Australian household waste management system. The application of the smart resource tracking system will be implemented through the following ways: (i) mobile application-based resource tracking system used to measure the household’s material flow; (ii) RFID, smart image and weighing system used to track waste generation, recycling and contamination; (iii) informing and motivating manufacturer and retailers to improve their problematic products’ packaging; and (iv) ensure quality and reliable data through open-sourced cloud data for public use. The smart mobile application, imaging, radio-frequency identification (RFID) and weighing technologies are not new, but the very straightforward idea of using these technologies in the household resource consumption, waste bins and collection trucks will open up a new era of accurately measuring and effectively managing our waste. The idea will bring the most urgently needed reliable, data and clarity on household consumption, recycling behaviour and waste management practices in the context of available local infrastructure and policies. Therefore, the findings of this study would be very important for decision makers to improve resource productivity in the waste industry by using smart resource tracking system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20devices" title="smart devices">smart devices</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20application" title=" mobile application"> mobile application</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20sensors" title=" smart sensors"> smart sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20tracking" title=" resource tracking"> resource tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20productivity" title=" resource productivity"> resource productivity</a> </p> <a href="https://publications.waset.org/abstracts/109694/improving-waste-recycling-and-resource-productivity-by-integrating-smart-resource-tracking-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109694.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">144</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">3270</span> Stream Channel Changes in Balingara River, Sulawesi Tengah</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhardiyan%20Erawan">Muhardiyan Erawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaenal%20Mutaqin"> Zaenal Mutaqin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Balingara River is one of the rivers with the type Gravel-Bed in Indonesia. Gravel-Bed Rivers easily deformed in a relatively short time due to several variables, that are climate (rainfall), river discharge, topography, rock types, and land cover. To determine stream channel changes in Balingara River used Landsat 7 and 8 and analyzed planimetric or two dimensions. Parameters to determine changes in the stream channel are sinuosity ratio, Brice Index, the extent of erosion and deposition. Changes in stream channel associated with changes in land cover then analyze with a descriptive analysis of spatial and temporal. The location of a stream channel has a low gradient in the upstream, and middle watershed with the type of rock in the form of gravel is more easily changed than other locations. Changes in the area of erosion and deposition influence the land cover changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brice%20Index" title="Brice Index">Brice Index</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=deposition" title=" deposition"> deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=gravel-bed" title=" gravel-bed"> gravel-bed</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20cover%20change" title=" land cover change"> land cover change</a>, <a href="https://publications.waset.org/abstracts/search?q=sinuosity%20ratio" title=" sinuosity ratio"> sinuosity ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=stream%20channel%20change" title=" stream channel change"> stream channel change</a> </p> <a href="https://publications.waset.org/abstracts/70833/stream-channel-changes-in-balingara-river-sulawesi-tengah" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70833.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">328</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">3269</span> Assessing the Suitability of South African Waste Foundry Sand as an Additive in Clay Masonry Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nthabiseng%20Portia%20Mahumapelo">Nthabiseng Portia Mahumapelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Andre%20van%20Niekerk"> Andre van Niekerk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ndabenhle%20Sosibo"> Ndabenhle Sosibo</a>, <a href="https://publications.waset.org/abstracts/search?q=Nirdesh%20Singh"> Nirdesh Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The foundry industry generates large quantities of solid waste in the form of waste foundry sand. The ever-increasing quantities of this type of industrial waste put pressure on land-filling space and its proper management has become a global concern. The South African foundry industry is not different when it comes to this solid waste generation. Utilizing the foundry waste sand in other applications has become an attractive avenue to deal with this waste stream. In the present paper, an evaluation was done on the suitability of foundry waste sand as an additive in clay masonry products. Purchased clay was added to the foundry waste sand sample in a 50/50 ratio. The mixture was named FC sample. The FC sample was mixed with water in a pan mixer until the mixture was consistent and suitable for extrusion. The FC sample was extruded and cut into briquettes. Water absorption, shrinkage and modulus of rupture tests were conducted on the resultant briquettes. Foundry waste sand and FC samples were respectively characterized mineralogically using X-Ray Diffraction, and the major and trace elements were determined using Inductively Coupled Plasma Optical Emission Spectroscopy. Adding purchased clay to the foundry waste sand positively influenced the workability of the test sample. Another positive characteristic was the low linear shrinkage, which indicated that products manufactured from the FC sample would not be susceptible to cracking. The water absorption values were acceptable and the unfired and fired strength values of the briquette’s samples were acceptable. In conclusion, tests showed that foundry waste sand can be used as an additive in masonry clay bricks, provided it is blended with good quality clay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foundry%20waste%20sand" title="foundry waste sand">foundry waste sand</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20clay%20bricks" title=" masonry clay bricks"> masonry clay bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rupture" title=" modulus of rupture"> modulus of rupture</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a> </p> <a href="https://publications.waset.org/abstracts/105027/assessing-the-suitability-of-south-african-waste-foundry-sand-as-an-additive-in-clay-masonry-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105027.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">230</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">3268</span> Harvesting Alternative Energy: Exploring Exergy, Human Power, Animal Body Heat, and Noise as Sustainable Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Yazdandoust">Fatemeh Yazdandoust</a>, <a href="https://publications.waset.org/abstracts/search?q=Derrick%20Mirrindi"> Derrick Mirrindi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The excessive use of non-renewable fossil fuels has led to a pressing energy crisis that demands urgent attention. While renewable sources like solar, wind, and water have gained significant attention as alternatives, we must explore additional avenues. This study takes an interdisciplinary approach, investigating the potential of waste streams from energy production and other untapped natural sources as sustainable energy solutions. Through a review of case studies, this study demonstrates how these alternative sources, including human power, animal body heat, and noise, can seamlessly integrate into architecture and urban planning. This article first discusses passive design strategies integrating alternative energy sources into vernacular architecture. Then, it reviews the waste stream (exergy) and potential energy sources, such as human power, animal body heat, and noise, in contemporary proposals and case studies. It demonstrates how an alternative energy design strategy may easily incorporate these many sources into our architecture and urban planning through passive and active design strategies to increase the energy efficiency of our built environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20energy%20sources"
