An assessment of the recycling potential of materials basedon environmental and economic factors; case study in South Korea

As the generation of waste home appliances increases continuously with economic growth, the importance of recycling becomes more apparent. Many home appliances we use today are recyclable, and recyclable materials from the waste home appliances can be used to create new or refurbishing products. To do that, first of all, we have to know and consider the recyclable materials' recycling potential with environmental and economic information. In this study, an evaluation method to assess recycling potential considering both the environmental and economic factors was suggested for the materials recovered from waste home appliances. Life cycle assessment (LCA) method was applied to obtain the environmental score (S_Env) and an actual value and a static economic model was used to obtain the economic score (S_Eco). The recycling potential for recyclable materials was calculated by using the S_Env and S_Eco along with weighting factors derived from an analytical hierarchy process (AHP) method. With the calculated data and evaluation method for the recycling materials, this study could provide useful information for decision makers and product designers in the design for environment (DfE).
