Mombetsu Biomass Electric Power uses incineration ash from the biomass boiler to manufacture a foundation fill material (product name "Rovander") for forest roads, thereby reducing the generation of waste and associated environmental impact toward recycling-oriented business operations in which byproducts from power generation using forest resources are utilized for reforestation. The product has been certified as a recycled product by the Hokkaido government by meeting the environmental safety standards set by the government.

The overall recycling rate in our power generation business was 96.8% in fiscal 2024 and increased to 99.3% in fiscal 2025.
