Clean Factories - Factory Energy Conservation

Beijing, Matsushita Color CRT Co., Ltd. (BMCC) produces cathode ray tubes for TVs. In the past, the company heated the pure water used in the production process through heat exchange using steam, but has now started to use the waste heat from air compressors as a heat source for raising the temperature of the water. As a result, the company reduced the use of steam by 11,333 tons a year, and per unit production by 5% by utilizing the waste heat from the air compressors and also from the heating furnaces. The company received a prize at the internal energy conservation competition held by the Group for its sites in China in fiscal 2007
