In December 2004, Cabot entered into a 2nd Joint-venture contract with Shanghai Coking & Chemical Corporation to establish Cabot Chemical (Tianjin) Co., Ltd. in TEDA, Tianjin. Two production lines of Unit I were put into operation in May and June, 2006 respectively to realize annual capacity of 110,000 tons high quality reinforced and semi-reinforced rubber carbon black products. In September 2009, expansion project of Unit II was successfully put into production. The plant is expected that total production capacity will reach 260,000 tons high quality carbon black upon the completion of Unit II. Being highly committed to environment protection, the company invested the capital equivalent to that used for construction of 10 carbon black production lines in domestic to install the first desulphurization and de-nitrification equipment in China to minimize the impacts on the surrounding environment. Meanwhile, waste heat recycling center was built to use tail gas to generate electricity power supplying to the company and adjacent plants.
