Construction of Shizuoka Prefecture’s First Sludge-Derived Fuel Production Facility Completed at Nakajima Sewerage Treatment Plant
Contributing to effective use of sludge and greenhouse gas reduction

 METAWATER Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Yasushi Nakamura; hereinafter “METAWATER”) started the construction of a sludge-derived fuel production facility in December 2013, pursuant to the “Shizuoka City Nakajima Sewerage Treatment Plant Sludge-Derived Fuel Production Project” contract. A ceremony was held in commemoration of the recently completed construction.
Under this project, sewage sludge is recycled as carbide at the Nakajima Sewerage Treatment Plant. As the DBO method is adopted, the METAWATER Group is responsible for designing, constructing, operating and maintaining the sludge-derived fuel production facility.
Sewage sludge that has been disposed of as industrial waste so far will be recycled as energy resources, producing 1,362 tonnes of carbide per year

Shizuoka Prefecture’s first sewage-sludge-derived fuel production project
This project is Shizuoka Prefecture’s first sewage-sludge-derived fuel production project. The carbide generated will be used as carburizing material at melting resource recycling facilities and steelmaking plants.
Through this project, METAWATER will strive to contribute to the region’s sustainable development and expand the use of renewable energy, aiming for further greenhouse gas reduction
