Advanced environmental facilities "cleanse" the emissions from the incinerator in the high-voltage chimney which collects dust and pollutants, and ensures that the emitted fly ash meets national standards. Plus, the solid residue can be used as raw material in the cement industry.

The Lujiashan incinerator was built at record speed. It was completed in two years, in 2012, for a cost of 2.1 billion yuan ($350 million) and was co-funded by Shougang and the Beijing municipal government. Before starting construction, Shougang obtained more than 80 approvals in three months, a process for which similar projects normally require several years. Another advantage of the project is that the land on which the incinerator has come up belongs to Shougang, which saved the company the trouble of seeking the consent of residents in and around the area, which is the standard practice.

No wonder, Shougang is using the project as a showcase for the recycling industry, and the industry administration department has praised it for easing the environmental pressure, even if temporarily, on the Beijing government.

The Beijing local government had promised to build four waste incinerators around Beijing city by 2008, increasing the number to nine before 2015. But local residents' fierce opposition to such projects because of fear of pollution thwarted the plan. As a result, only one small incinerator could be built in the east of Beijing by 2009.

In the meantime, the waste generated by Beijing residents rose from less than 5 million tons in 2003 to about 7 million tons in 2013, with the volume expected to rise to more than 8 million tons next year. Complicating the situation is the fact that only 13 percent of Beijing's land area can be used as landfill sites, according to the city's land use plan, making the use of large areas as landfills impossible. Besides, the side effects of landfills, such as soil and water pollution, are harmful to the environment.

Once the Lujiashan goes into full operation, the Beijing authorities expect 40 percent of the city's household garbage to end up in incinerators next year. Without Lujiashan, which is part of the local government's plan, this goal could not have been met.

Although Beijing increased the household garbage disposal fee from 25 yuan per ton to 300 yuan per ton next year, it still cannot cover the cost of waste processing, not least because despite the authorities urging people for the past several years to sort household garbage at source, most of the basic sorting work is done at landfill sites.

Therefore, the Beijing government has to take effective measures to raise public awareness about garbage disposal and environmental protection. And people, on their part, have to understand that sorting garbage at source is the starting point of environmental protection.
