SDK to Install GHG Decomposition Unit

Showa Denko K.K.
January 11, 2008

Showa Denko K.K. (SDK) has decided to install a greenhouse gas (GHG) decomposition unit at its Kawasaki site for start-up in March 2009. The installation of the unit will enable SDK to reduce GHG emissions by 6% in compliance with the Kyoto Protocol without relying on emission trading.

Specifically, SDK will install a unit to recover and decompose perfluorocarbon (PFC) and hydrofluorocarbon (HFC) gases emitted partially in the course of production and filling of these gases at Kawasaki. SDK manufactures and sells PFC for use as etching and cleaning gases for semiconductor production, and HFC for use as refrigerant.

While various measures have been taken to reduce the emission, SDK has decided to install the unit to further step up reduction efforts. Recovered PFC and HFC gases will be decomposed by combustion and most of the resultant fluorine compounds will be used as raw material for the production of chemicals. Almost all PFC/HFC emissions at Kawasaki will be eliminated as a result of the installation of the unit.

The Showa Denko Group is taking other GHG reduction steps as well, including the improvement of energy efficiency of production facilities and expansion of greenbelts at respective operation sites. Thus, the Group will reduce GHG emissions for the 2008-2012 period under the Kyoto Protocol by 6% on the average without relying on emission trading. Furthermore, SDK will consider long-term strategies for GHG emission reductions by 2020 and 2050.

The New Energy and Industrial Technology Development Organization (NEDO) has decided to support SDK’s installation of the PFC/HFC decomposition unit as part of NEDO’s 2008 program for combating global warming.
