A new waste disposal plant in Shikoku that uses a cost-effective, environmentally friendly composting method is drawing interest from other municipalities needing to replace aging waste disposal facilities.

Located in a mountainous area of Mitoyo, Kagawa Prefecture, the Biomass Recycling Center Mitoyo went into operation in April. It neither resembles a typical waste plant nor emits unpleasant odors or fumes.

The center, with 4,000 sq. meters of floor space, is Japan's first waste disposal facility based on technology called "tunnel composting." The method uses microorganisms to decompose waste and produce fuel.
