The Saitama Project

The raw compost produced in the Bedminster Digester is utilized as an alternative raw material and fuel for the cement manufacturing process at the Saitama Plant.

The raw compost is fed into an adjacent cement kiln after sieving and storage. Actual operation at the Saitama Plant, Saitama, Japan commenced in April 2001, by using municipal waste (garbage and burnable materials such as plastics and paper) generated from Hidaka City, Saitama. The plant has a capacity to treat 15,000 tons per year of such waste and the Bedminster operation has been very successful.
