[Assessment and design of material cycles and waste management systems and related policies]
Is recycling good for the environment? What should we pay attention to in treating and recycling waste? To answer questions such as these, I have conducted research to design desirable material cycles and waste management systems and related policies, and to assess various systems and policies. For this purpose, methodologies such as life-cycle assessment (LCA), material flow analysis (MFA), environmental accounting, and input-output analysis (IOA) are used.
Related research activities include LCA of packaging waste recycling (ref. 1), development of indicators for describing society’s metabolism based on MFA (ref. 2), and development of environmental accounting framework for municipal solid waste management (ref. 3).
[Assessment and design of forest sector carbon cycles and related climate policies]
How much can forest and wood products contribute to the mitigation of climate change? How should they be treated in international treaties such as the Kyoto Protocol? To answer questions such as these, I have conducted research to estimate flows and stocks of carbon contained in forest and wood products, and to examine the potential mitigation of climate change by using forest and wood products.
Related research activities include estimation of accumulated carbon as wood products in industrialized countries (ref. 4) and assessment of treatment of forest sinks in the Kyoto Protocol (ref. 5).

| Future Plan |
|
I am planning to conduct basic studies to create an ideal cycle-oriented society, which include very basic question that what a cycle-oriented society is (ref. 6). Please contact me if you are interested in questions such as “What are the concepts, objectives, and policies of a cycle-oriented society?” “What is the relationship between a cycle-oriented society and sustainable development?” “What are the appropriate indicators by which to measure a cycle-oriented society?” |
