Impact of Trash Bin Arrangement Preference on Waste Segregation Efficiency

Abstract

The initial stage of waste management flow chart is waste collection. Used tools for waste collecting are well-known as trash bins or trash containers. Although trash bins seem to relate to waste separation efficiency, only a few researches are concerned about the impact of trash bins on waste segregation. Trash bins are designed to encourage waste segregation of recyclable and non-recyclable wastes in public. Normally, there are four kinds of trash bins set for waste disposers; trash bins for combustible waste (burnable waste; BU), incombustible waste (NC), PET bottles (PE), and cans (CA). A previous study of the authors researched on psychological preferences of trash bins arrangement (Jiang et al. (2017) Proceedings of the 8^th China-Japan Joint Conference on material recycling and waste management, 206-209, Hangzhou, 16-20th Sep.). In this study, the authors would like to know the impact of four trash bin arrangement preferences, which was quantified by questionnaire surveys, on real waste segregation efficiency.
