Asia’s largest incinerator to supply 300 mln KWh to Beijing residents

March 07, 2012

When completed in October of this year, Asia’s largest incineration plant will be capable of processing 3,000 tonnes of  trash per day and while providing 300 million kWh of power per year to Beijing’s residents.

According to Zhe Jimin, chairman of the Shougang Group, which has invested more than 2 billion yuan (USD317 million) in the project, power and heat generated through processing up to 25 percent of the Chinese capital’s refuse will supply electricity to four city districts: Mentougou, Shijingshan, Haidian and Fengtai.

Speaking at a news conference on Monday, Zhu said the group, one of China’s largest iron and steel companies, is also conducting research and development into transforming food waste into organic materials and oil products in order to prevent it from being used to produce "gutter oil" in the catering industry or causing pollution at landfill sites.

"The plant will be located in a mining area in the city's western outskirts in Mentougou district, which is sparsely populated, to limit the impact of its emissions of ash, cinder, dioxin and volatile heavy metals such as manganese on the public," said Mao Da, an expert in solid-waste management at Beijing Normal University.

Composting, landfill and incineration are the three major ways garbage is treated in China. Mao said that composting is not a practical option, as this only works effectively if the waste is biodegradable, such as food waste and garden garbage, and there are few available sites for landfill, leaving incineration as the only option.

Gaoantun, in Beijing's Chaoyang district, is currently the biggest garbage incineration plant in China. It processes 1,600 tonnes of garbage every day and produces an annual energy output of 200 million kWh.
