Manufacturing Group to Use Biomass to Slash CO2 Emissions

The Teijin Group, a leading Japanese manufacturer of fibers, plastics, and pharmaceuticals, has launched a biomass fuel project that, when completed, will reduce the total amount of carbon dioxide (CO2) emissions from its companies in Japan by an estimated 65,000 tons a year, corresponding to 2.6% of their CO2 emissions in fiscal 1990.

As fuel for a new circulating fluidized bed boiler, Teijin Techno Products Ltd. will use wood biomass fuels, such as bark and wood chips from lumber mills or construction waste, as well as recycled fuels, such as refuse paper and plastic fuel (RPF) and used tires. The boiler will be built at the Teijin Group's Mihara Factory in Mihara City, Hiroshima Prefecture by December 2006. By replacing 36% of its current coal consumption with these alternative fuels, the company will reduce CO2 emissions by 33,000 tons a year.

Teijin Fibers Ltd. has been working on a project to burn pulverized wood biomass together with coal in an existing pulverized coal-fired boiler at its Matsuyama Factory in Matsuyama City, Ehime Prefecture. It recently scored a success using a 5% mixture of wood biomass, and the company plans to continue its efforts to increase the ratio of biomass up to 10%. This could lead to everyday, practical operation of this co-firing system and an annual reduction of 32,000 tons of CO2 emissions.

The two companies are considering local procurement of wood biomass and recycled fuel materials, so the project is also expected to help establish a recycling-based community in each respective area.
