Biomass Power System

Sustainability is Integral to Harima's Corporate Mission

The biomass power plant completed in March 2005 was recognized by the Ministry of Economy, Trade and Industry's 2003 new energy business promotion initiative as a biomass power business fueled by waste oil generated when crude tall oil extracted from pine trees is refined.
The steam and power generated by this facility covers the steam and power needs of the entire Kakogawa site, with surplus electricity being supplied to a power company. Harima Chemicals Group's utilization of biomass fuel effectively cuts annual carbon dioxide emissions by 30,000 tons.
