Toyohashi City's Total Waste Utilization System

Abstract

The new treatment plan for waste materials in Toyohashi produces thermal energy, organic compost, and material for landfill projects out of waste material and recovers waste materials which can be recycled for re-use. The resource recovery and waste treatment centre consists of five parts: an incinerator, a high-rate compost production unit, a human faeces treatment unit, a resource recovery unit and a chicken manure treatment unit. This combination results in a saving of heat energy and materials used in the waste treatment processes. Non-combustible wastes, together with ashes and other residue are buried in large sunken fields and serve as the base for farmland reclamation projects. To provide the optimum treatment and utilization of waste materials it is necessary to separate the waste materials into separate categories before it is collected. Citizens co-operate by separating waste materials into five types at home, office wastes are separated into three different types. The centre has been operated satisfactorily since April 1980.
