Abstract
In home appliance recycling system, informal collections are considered as the source of many problems, such as losses and/or dispersion of recycling potentials, potential environmental pollutions and the exports of non-reusable wastes in the name of reusing. In this recycling system, various stakeholders exist, such as consumers and informal collectors, and they make their own individual decision-makings. When any policy to tackle those problems is considered, it is necessary to understand the policy’s impact both on each stakeholder’s individual behavior and the whole system. However, there are few quantitative studies, because the whole system is complicated and difficult to model, especially including the informal collection. The objectives of this study are modeling the recycling system and quantitatively evaluating the impacts of policies on this system and its stakeholders, using multi-agent simulation. The conclusions are following two. First, the impact of eco-point system of end-of life home appliances was quantified, and it was proved that this system greatly contributes to formalize disposal behavior of consumers. Second, the relation between consumers’ environmental consciousness and their disposal behavior was quantified.
