Peking zavedl recyklaci odpadů v olympijských oblastech


Beijing kicked off a waste collection and recycling project Wednesday in all Olympic venues, about two weeks before the opening of the summer Games.

Based on the expected volume of spectators, the 31 venues in the city are expected to jointly produce some 14,000 tonnes of trash, including leftovers, paper, plastic bottles and medical waste, during the sports events, according to the Beijing Municipal Administration Commission.

Beijing has pledged to make 50 percent of this waste useful after recycling, a common standard fulfilled by most host countries of the Games.

Food waste must be moved away from stadiums within four hours and other rubbish will be cleared up and transported to four sorting centers and processing plants in Beijing's suburbs after matches, according to the commission.

In addition, water recycling measures have been adopted on some Olympic sites since March, which will help the city to save 30 million cubic meters of clean water a year, said Wang Hongchen, chief engineer with Beijing Sewage Company in charge of the project.

After filtering, reverse osmosis, active carbon absorption, ozone oxygenation and other advanced treatments by a sewage plant and two water recycling plants, recycled water will become safe enough for reuse, according to Wang.

Since 2001, six sewage factories have been operating to provide2.54 million cubic meters of water a day for industry, farming, sightseeing lakes, and forestation needs.

Water saving has been a primary task. The city used 4 billion cubic meters of water in 2000 and 3.4 billion cubic meters last year, a saving of almost 100 million cubic meters a year.

In 2007, it used 480 million cubic meters of recycled water, or14 percent of the total water supply, to supplement watercourses, car washing and crop irrigation.
