District to Construct Waste Treatment Stations Near Canteens and Restaurants
Yantian District in Eastern Shenzhen is piloting a program that will transform kitchen waste into organic fertilizer. Kitchen waste treatment stations are constructed near canteens and restaurants where solid and kitchen wastes are being processed.
Solid wastes are dehydrated and converted into fertilizer and liquid wastes that have edible oils and fat will be processed into biodiesel. The treatment stations are being built based on Yantian’s existing domestic waste transfer stations. So far there are 260 tons of domestic waste is being produced in Yantian every day, these include 88 tons of kitchen waste. The district proportion of kitchen waste is fairly above the city’s average of 18 percent as reported by the district urban management administration. The high rate of kitchen waste is due to the fact that around 10 million people visit the district every year during the holidays and for leisure.
Before the treatment measure was introduced most of the kitchen wastes produced in Yantian was sold to pig raisers outside Shenzhen, which in turn have polluted the environment due to the process of unsealed transportation, furthermore some small restaurants and households are throwing kitchen waste without classification. While the district says that it’s no small task to have every household to classify domestic waste from kitchen waste into proper trash cans, the district will still push through its plans in piloting a garbage classification program in its 30 residential communities.
The district efforts in treating waste is part of the city’s work in promoting garbage classification and to provide a better waste treatment.
