BEIJING -- China's capital plans to get rid of the foul-smelling slops collection carts that scavenge for food waste and resell it as pig swill, with many to disappear ahead of the 2008 Olympic Games, state media said Thursday.

The carts, usually pedalled by migrant workers, carry an open metal barrel on the back for collecting the scraps and trail a powerful stink in their wake.

The Beijing Morning Post said Thursday that the city was drawing up a more hygienic system for collecting the estimated 1,200 tons of kitchen waste generated by the city each day.

At least 122 Olympics-endorsed restaurants and 31 hotels will have their waste handled by the new system ahead of the Games, the paper said, without giving specific details.

All the city's estimated 30,000 cafes, restaurants and hotels as well 170,000 school and work canteens will be serviced by the new waste collection system by 2010, it said.

"This means that the privately owned slops carts will soon no longer be seen in the capital," the paper said.

It's the latest effort by Beijing authorities to clean up the city and ensure that the best image is presented to the hundreds of thousands of visitors expected next summer.

Etiquette campaigns are afoot to stamp out bad manners such as jumping ahead in line, spitting, littering and reckless driving. Menu names are being revised as part of an effort to ban unintelligible English, known as "Chinglish," that abounds on signs everywhere.
