Sumitomo Osaka Cement to use more ash
Published: 06 June 2005

The use of incinerator ash as a raw material in cement is to be increased by Sumitomo Osaka Cement. The company plans to have all of its plants set up to use the ash within three years.  However, in order to use incinerator ash in cement, a system that removes chlorine from the ash must be attached to the kiln.  The company currently has such facilities at three of its five plants and intends to install the necessary equipment at the remaining two plants in the next three years at a cost of up to 600 million yen (US$5.56m).
