Asia's largest household refuse incineration plant, which is under construction in Beijing, will become operational in October and have a daily processing capacity of 3,000 tons.

The plant is expected to handle one-fourth of the city's trash, and its annual energy output will exceed 300 million kilowatt hours.

Power and heat generated by the plant will be supplied to all four districts in western Beijing, namely Mentougou, Shijingshan, Haidian and Fengtai, Zhu Jimin, chairman of Shougang Group, one of China's largest iron and steel companies, which invested more than 2 billion yuan ($317 million) in the project, said at a news conference on Sunday.
