Waste management is one of the most crucial topics of the sustainability concept. In Turkey, waste management of the small household appliances under waste of electrical and electronic equipment (WEEE) category still remains as an issue to handle although its production is very large and long-established. The main reason is that many of the household appliances' wastes are not properly treated in waste management process despite the fact that Turkey has recovery and collection targets. This outboard of wastes non-treated in an environmentally friendly way, such as recycling or reuse, gives rise to environmental damage. The aim of this paper is to integrate a system dynamics and fuzzy cognitive mapping model in order to evaluate and develop recovery options of small household appliances' wastes which are not treated according to the regulations in Turkey. The first part of the proposed model is to build a system dynamics model by developing recovery options for small household appliances' waste management while the second part is to evaluate the relations between supporting factors of recovery options by using Fuzzy Cognitive Mapping.
