Abstract
From the point of view of securing resources of rare metals, construction of resource recovery system from small appliances is being considered. However, it cannot be said that careful consideration has been done for their design method. We the autho rs have manually disassembled 365 products of various small appliances so far, and have accumulated information such as material composition to build a database for domestic appliances. In this paper, small domestic appliances were put to the crushing and screening experiment, which was carried out at a treatment facility in Saitama prefecture, for collecting various resources to investigate their material compositions. Then, our domestic appliances database was exploited in leading the relevance between the input objects and output particles in treatment facilities. Thereby, it was made possible to estimate output particles from the material compositions of input objects. In addition, from the perspective of economic efficiency and environmental performance, a selection method of optimal product group as input object was constructed.
