In response to these changes, social systems that support proper waste management and sound material cycles must also change. In this research, we conduct social surveys, case studies, material flow analysis, model simulation, policy evaluation, stakeholder analysis, and so on. Our aim is to support target setting and strategic policy formulation on national and local levels, provide solutions to maintaining waste treatment systems and advancing circular systems, and develop methods for understanding the dynamics of chemical substances in the processes of waste treatment and material cycles.</p> <div class="pagetop"><a href="#research" class="sub-pagetop">PageTop</a></span></div> </dd> </dl> </section> <section class="section" id="subject02"> <dl class="section-list"> <dt class="h5-header">Sustainability assessment and future vision design on material use</dt> <dd> <p>In this research, we work on specifying and designing institutions for production and consumption systems that enable sustainable material use at multiple scales. Our approach to these issues includes modelling and analysing material flows/stocks and assessing the risk and criticality of materials, with a focus on environmental, economic and social impacts. We also develop data visualisation methods to assist diverse stakeholders in understanding sustainable material use.</p> <div class="pagetop"><a href="#research" class="sub-pagetop">PageTop</a></span></div> </dd> </dl> </section> <section class="section" id="subject03"> <dl class="section-list"> <dt class="h5-header">Research on advanced science and engineering to support sustainable material cycles</dt> <dd> <p>This research aims to provide advanced science and engineering solutions to the environmental problems that are foreseen in material cycles in near future by taking an approach that integrates chemical and material analysis; risk assessment; and chemical and environmental engineering. With consideration of creating a decarbonized society and ensuring safety, this research establishes analysis and assessment methods for nano-plastics and develops carbon cycle technologies. These fundamental knowledge and technologies support core technologies for sustainable material cycles and regional circular economy. The research pursues collaboration with other institutions to contribute to various environmental policies, and to implement the developed technologies in the society.</p> <div class="pagetop"><a href="#research" class="sub-pagetop">PageTop</a></span></div> </dd> </dl> </section> <section class="section" id="subject04"> <dl class="section-list"> <dt class="h5-header">Measurement, testing, and evaluation of hazardous or valuable substances</dt> <dd> <p>This research focuses on the following themes with the aim to create a sound material-cycle society in harmony with the environment.</p> <ul> <li>Clarification of emissions and worker exposure status of particulate matters such as microplastics and asbestos</li> <li>Elucidation of behavior of new POPs* and POPs candidates in product lifecycles</li> <li>Assessment of hazard and resource potential of metals and other substances contained in waste incineration residues</li> <li>Standardization of testing methods for evaluating environmental safety quality of recycled materials in construction</li> <li>Development of fundamental technologies for enhancing green infrastructure function by using recycled materials</li> </ul> <p>*POPs: Persistent Organic Pollutants</p> <div class="pagetop"><a href="#research" class="sub-pagetop">PageTop</a></span></div> </dd> </dl> </section> <section class="section" id="subject05"> <dl class="section-list"> <dt class="h5-header">Waste management engineering research on technology advancement and adaptation</dt> <dd> <p>This research focuses on development of advanced technologies and systems that contribute to improving sanitary conditions and environmental safety of the material cycles and waste management technologies in Japan.

Plastic production and incineration emit carbon dioxide (CO<sub>2</sub>) contributing to the climate change. When not collected properly, used plastics are discharged into the environment, partially degraded into microplastics, and may affect marine ecosystems and fish species they host, which is becoming a serious concern. We will find appropriate ways to monitor and evaluate these environmental impact of plastics from a broad perspective, and devise technological and social systems that can reduce the environmental impacts, in collaboration with researchers from a wide range of fields beyond the material cycles domain.</p> <div class="pagetop"><a href="#research" class="sub-pagetop">PageTop</a></span></div> </dd> </dl> </section> <section class="section" id="subject08"> <dl class="section-list"> <dt class="h5-header">Environmental emergency management<br>(Environmental Emergency Management Office )</dt> <dd> <p>Environmental Emergency Management Office provides technical assistance to enhance treatment, disposal and recycling of disaster waste and to improve management of hazardous chemical substances and asbestos-containing materials that have a risk of spreading after disaster events.
