Abstract
It is time for houses to group and play their roles in waste management in order to support material recycling. As the first step we investigated the waste composition thoroughly in part 1. To promote separate collection, facilities around houses and economic instruments can be introduced. Through the questionnaire delivered to residents and students living in Tokyo and neighboring prefectures, essential factors for separate collection, and specifications and requisites for storage, waste collecting stations, recycling centers were grasped. The effects of deposit systems were also analyzed with conjoint analysis method. If such conditions were fully fulfilled, consumers are ready to separate 70-80% of materials to recycling.
