Caojing, China-Bayer MaterialsScience AG has raised the size of the methylene diphenyl diisocyanate facility it is planning to build at the firm's Caoijing chemicals complex in China to 350 kilotonnes per annum. This is 120 000 tonnes more than the original MDI capacity planned for Caojing, and is intended to meet the 6 percent annual growth in MDI demand BMS is predicting, said a company spokesperson. This capacity increase will make the Caoing plant, scheduled for start-up in 2008, "the largest of its kind in the world," said a 30 June BMS announcement.Environmental audits are complete, so BMS has the important approvals it needs to begin construction, the statement added. "We are looking to increase our annual MDI production capacity from current levels of approximately 930 000 tonnes to 1.3 million tonnes per year," said Dr Udo Oels, Bayer AG's board member responsible for Asia. Oels was at Caojing to inaugurate a new 40 ktpa polycarbonate compounding plant. The plant in China will "make a significant contribution" to BMS' projected 1.3 million tonnes a year goal, Oels added. Oels also announced that the Bayer MaterialsScience Trading Co., headquartered in Shanghai, is to be set up on 1 Aug 2005, to enable BMS to sell its products directly to the Chinese market. "
