Development of recyclability evaluation tool

摘要

In this paper a new method of recyclability evaluation is proposed and an embedded tool to apply it is also presented. In this method, the recyclability of a product is given by summing up recyclabilities of all units to which the product is manually disassembled. The recyclability of a unit is calculated, if all names and amounts of materials of which the unit is composed are known. The recyclability of disassembled unit, consisted of multiple numbers, is judged by the grounds of tramp element in metals and compatibility of plastics. Recyclability of a long-lifetime product can be estimated from recyclabilities of units, which are modeled as probabilistically distributed degradation of materials.
