Japan: Report on the Social Experiment of Garbage Grinder Introduction

To fully assess the potential benefits and impacts of food waste disposers, Japan‘s Ministry of Land, Infrastructure & Transport—in cooperation with the Hokkaido government and Town of Utanobori—designated Utanobori as the subject area for a disposal field test conducted over four years, from 2000 through 2003. The study assessed the impacts of disposals on the sewage system, solid waste collection, local economy and environment, as well as the daily lives of town residents. Findings of the technical report on the study included that popularization of disposers would cause no changes to the environmental burden, and that the convenience benefits coupled with the cost of purchasing and installing a disposer provided an excellent value compared to any changes in administrative and disposal operation costs.
