From sludge to cement

GUANGZHOU: A plant capable of treating more than 60 percent of the city's sewage sludge, the smelly remainder after wastewater is disposed of, went into operation yesterday.

The firm, Guangzhou Heidelberg Yuexiu Cement Co Ltd, will be able to handle 600 tons of the sludge every day in a smell-free way.

Guangzhou produces about 950 tons of sludge a day at present. The figure is expected to reach 2,425 tons next year and 3,120 tons in 2020.
