Rengo Commences Operations at Fukushima Yabuki Plant
Green Corrugated Production Center Meets Daytime Energy Needs with Solar Power

Rengo Co., Ltd. (Head Office: Kita-ku, Osaka; President & CEO: Kiyoshi Otsubo) announces it will officially commence operations today at the Fukushima Yabuki Plant (Yabuki-machi, Nishishirakawa-gun, Fukushima Prefecture), in place of Rengo’s former Koriyama Plant (Koriyama City, Fukushima Prefecture).

The plant employs an integrated production line—from corrugated board manufacturing to the converting of various types of corrugated boxes—using cutting-edge production equipment and an advanced production management system that combine product quality with energy efficiency. At the same time, the new plant brings together all of the environmental technology and expertise in resource and energy efficiency that Rengo has developed to date, from supplying all of its daytime electricity needs through solar power generated from approximately 9,000 solar panels to its use of Liquefied Natural Gas (LNG) as boiler fuel. Utilization of these innovations is expected to cut CO2 emissions by 40% compared to the old Koriyama Plant.

“Less Weight, Less Carbon.” At the Fukushima Yabuki Plant, Rengo will manufacture the ideal green corrugated product: corrugated board that is lightweight, strong, thin and takes up less storage space, and whose lifecycle emits only small amounts of CO2—attributes best represented by Rengo’s 4-mm thick C-flute corrugated board. While continuing to meet the packaging needs of its customers with unwavering quality, Rengo will use its unique and environmentally considerate corrugated board to positively contribute to the future of humanity and the Earth.
