資源リスクとサステイナブルな資源利用への道

抄録

Current new stage of the resource risk is discussed. The risk is going no more the risk in future but that at today or tomorrow. There are two reasons namely demand of technological innovation and the explosive increase of global demand. This effect the sustainability not only that of the national economic, but also of human’s activity and of global environment. In order to understand the impact related global environment, “resource-end weight” gives explicit information for design of materials and products. For mitigation of the risk, four practices are proposed; reduce, reuse, recycle and substitute. Substitution is important approach to solve the problem. While conventional substitution was tried after the shortening of the resource, expected substitution should investigate to widen the utilization of common material precedingly. For the further trial to sustainable resource management, “good products from familiar resources” is required.
