Japanese cement manufacturer Taiheiyo Cement Corp will start recycling waste plasterboard at the company-owned land plot in Sodegaura, Chiba prefecture, eastern Japan, the company said on February 24, 2004.  Taiheiyo Cement plans to annually recycle 100,000t of waste plasterboard created from building dismantlement in order to produce 70,000t of anhydrous gypsum a year. The anhydrous gypsum, in turn, will be applied as a raw material for fixation agents.  The Tokyo-based company is today holding about 40 per cent of the domestic Japanese cement market, with 13 manufacturing bases in Japan, three in the United States, three in China, one in Vietnam and one more in the Philippines.
