Kurita Announces Participation in Hamura Biogas Power Generation LLC

Kurita Water Industries Ltd. (Head Office: Nakano-ku, Tokyo; President: Michiya Kadota; hereinafter "Kurita") is pleased to announce its participation in the special purpose corporation Hamura Biogas Power Generation LLC (hereinafter "Hamura Biogas").

Hamura Biogas was established under a plan by Archaea Energy Co., Ltd. (Head Office: Minato-ku, Tokyo; President: Tetsuya Ueda), which operates a waste processing consulting and biogas power generation business, with the aims of improving recycling rates for food waste, helping to reduce greenhouse gas emissions, and contributing to the creation of a recycling-oriented society. The Hamura Biogas Power Plant (Hamura-shi, Tokyo), which generates power using the biogas generated from methane fermentation with food waste as the raw material, was constructed in July 2020 and is scheduled to begin supplying power in this year.

Kurita decided to participate in Hamura Biogas out of its support for the project's purpose. Kurita will leverage the Kurita Group's strengths in the three business fields of water treatment chemicals, water treatment facilities and maintenance services while providing a comprehensive solution that includes the wastewater treatment facilities needed for a biogas power plant combined with appropriate facility operation and management expertise to contribute to the stable operation of the power plant.

In its MVP-22 (Maximize Value Proposition 2022) medium-term management plan, the Kurita Group has established "achieving renewable energy utilization" and "reducing waste" as priority themes for creating shared value with society. Biogas power generation projects not only reduce waste and greenhouse gases but also contribute to local community by, for example, facilitating local production for local consumption and supplying power to a region in the event of a disaster. Kurita will continue to offer comprehensive solutions including methane fermentation and wastewater treatment technologies while proactively advancing the widespread adoption of biogas power generation projects.
