Receipt of Order for “Area-wide Sewage Sludge Recycling Project in northen district of Akita Prefecture”

METAWATER Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Yasushi Nakamura; hereinafter referred to as “METAWATER”) is pleased to announce that it has received an order from Akita Prefecture for “Area-wide Sewage Sludge Recycling Project in northen district of Akita Prefecture” effective May 26, 2017.
The project aims to continuously treat sludge generated from the treatment of household waste water in northern Akita and reliably produce recyclable resources over the long term to supply them as valuable assets.
To treat various types of sludge collected from a wide area such as wastewater, human waste from non-flush toilets, purification tanks, and rural community sewerage, the project has adopted a fluidized-bed-type carbonization system, which is capable of responding to wide fluctuations in treatment volume and characteristics. In addition to ensuring stable production of recyclable resources, the scheme minimizes the consumption of auxiliary fuel and reduces the cost of operation and greenhouse gas emissions at the facilities by using most of the energy recovered from the sludge for the production of recyclable resources. Recyclable resources produced at the facilities will be used as a soil improver.
Northern Akita Eco-resource Management Co., Ltd. a special-purpose company represented by METAWATER, has received an order for maintaining and operating the project.
Through the project, METAWATER will contribute to building a new recycling-based society by fully ensuring project continuation and contributing to local communities.
