Abstract

The University of Tokyo has undertaken the construction of a new sorting collection system for municipal solid waste. Waste producers' cooperation in waste sorting is essential. Making use of an experimental operation in the Faculty of Engineering and Graduate School of Engineering, we conducted 2 interviews of the university constituent members before and after the experimental operation and 3 waste composition surveys in the Carts. As a result, most of the constituent members were shown to be cooperative in the sorting collection in the trial system, and that rapid progress in the recovery rate will meet our expectations in the university. We have also confirmed the consistency of the results between interviews and waste composition surveys. Thereafter, the university has modified the system and adopted a more efficient system.

Key words: trial system, municipal solid waste, interview, waste composition survey in the Carts
