Nippon Denko expands Kashima plant for waste recycling, adding new melting furnace

Nippon Denko Co., Ltd. announced on November 27, 2025, a decision to expand its Kashima Plant with an incineration ash melting furnace (No. 5) and common facilities for furnaces No. 5 and No. 6. This strategic move aims to enhance the company's incineration ash recycling business, which transforms general and industrial waste into harmless, valuable metals and slag, addressing the decreasing capacity of landfill sites.

The new incineration ash melting furnace No. 5 is projected to have an annual treatment capacity of approximately 35,000 tonnes and represents an investment of approximately 12 billion yen. Commercial operation for the No. 5 furnace is scheduled to commence in December 2027. The company plans to decide on the addition of incineration ash melting furnace No. 6 at a later, appropriate timing.

This expansion aligns with Nippon Denko's Medium/Long-Term Business Plan, announced on November 29, 2023, which targeted a gradual increase in incineration ash melting furnace capacity. The company anticipates no impact on its financial results for the fiscal year ending December 31, 2025, from this investment.
