Kitchen waste refers to deserted or uneaten refuse produced by household kitchens. It is heavy in weight and can not easily be disposed(处理)of like other garbage due to dampness.

Separating kitchen waste from other waste can help to reduce organic matter in landfills, reducing smell and waste liquid and protecting disposal equipment. It is therefore necessary to perform garbage classification when disposing of kitchen waste.

There are special garbage trucks to process kitchen waste. Labeled “Kitchen Waste”, the beds of the trucks are covered in a hermetic(密封的) metal topper to contain the smell of the rotting organic waste. There are two sizes of the trucks—the smaller ones are designed to move through narrow streets, especially in the old-fashioned hutong, the larger ones are for wider streets.

Everyday, they stop at the residential(居住的) communities in Xicheng district, pick up their kitchen waste and carry it to the kitchen waste transfer buildings nearby. And Fengrongyuan residential community is one of them. It has 10 residential buildings and 606 families. In the afternoon. Two garbage trucks arrive at the community to collect its kitchen waste. The community now has 31 sets of garbage cans. Every set has three cans in different colors, green for kitchen waste, blue for recyclable waste and grey for other garbage.

Yang Kun, an official of Financial Street office, said that if residents in the community can respect the waste regulations and make it a standard practice in their daily life, they could be rewarded for their efforts.

After the two trucks are loaded with kitchen waste at Fengronfyuan, they will leave for the Xibianmen garbage storage building, where they are weighed before driving to an area to unload. The building has six big boxes to contain the kitchen waste.

To save resources and promote the disposal of household waste, the first step is garbage classification as conducted by residents.
