Besides natural resources, garbage, if properly disposed, could generate power as well, according to the experts.

Beijing's first-ever two-in-one power plant using waste, is expected to start operating by the end of year. It will use 1,600 tons of waste a day.

The city generates 12,000 tons solid waste every day, according to statistics.

"Building a power plant fueled by waste is a win-win solution," said Wang Weiping, an expert with the Beijing-based Renmin University.

Beijing has witnessed a big increase in urban solid waste, from 3.17 million tons in 1990 to 5.4 million today.

The traditional disposal methods of burying waste, which requires large areas of land, and which subsequently emits poisonous gases, is completely outdated, Wang said.
