Brief Description of Research
To promote effective utilization of resource materials and proper management of hazardous substances in waste treatment/disposal and resource circulation, I am conducting analyses of material and chemical substances flow/stock and chemical emission especially focusing on waste treatment/disposal and recycling stages. I am developing methodologies and basic data for such analyses and conducting case studies. My interest includes materials/substances contained in consumer durables such as electric and electronic equipment as well as wastes in more broader sense, i.e. municipal and industrial waste. The analyses are being conducted by means of system analysis approaches, experimental analysis approaches (including field works), and utilization of governmental information such as data from Pollutant Release and Transfer Register (PRTR) system.
I am also working on product lifetime, which is a key parameter in dynamic estimation and analyses of waste generation and the contained materials/chemical substances. I have compiled reported data in Japan and other countries and studied their definitions, estimation approaches, etc. in a systematically manner. I have also been studying the trend of product lifetimes over years and approaches for estimating it. Recently I am trying to investigate the actual and expected product lifetimes by consumers and to analyze the determinants of them quantitatively. This will provide an evidences and factors for the gap between the actual product lifetimes and consumer expectations, which would be a base for making product lifetimes longer towards a circular economy.
