    Rengo Yashio Mill Completes Wood Chip Biomass Power Plant

    Rengo Co., Ltd. (Head Office: Kita-ku, Osaka; Chairman, President & CEO: Kiyoshi Otsubo) announces it has newly installed a wood chip biomass power plant at its Yashio Mill (Yashio-shi, Saitama Prefecture).

    Yashio Mill is Japan’s largest paperboard mill, producing approximately 850,000 tons of paperboard each year, such as containerboard. The newly completed power plant aims to diversify energy sources used for boiler fuel, which currently uses town gas as the primary fuel. The new power plant also aims to reduce CO2 emissions from Yashio Mill. The power plant uses woodchip, a by-product of construction, as its main fuel source, and will provide approximately 20% of the electric power required by the mill.

    In addition to promptly building upon the previous fuel switch from oil to the more environmentally-friendly town gas, Yashio Mill aims to thoroughly reduce CO2 emissions through the effective utilization of biomass resources. It expects to further reduce CO2 emissions by approximately 65,000 tons each year with the completion of the wood chip biomass power plant.

    Rengo actively works toward reducing its environmental impact by creating packaging with greater value and using fewer resources, always keeping resource and energy saving in mind with the key concept of “Less is more.”
