SHANGHAI cut by 4 percent the amount of non-industrial garbage processed in the first half of this year - thanks to a trial waste separation program, officials said yesterday.
According to Shanghai Greenery and Public Sanitation Bureau, the city processed 18,194 tons of non-industrial waste - also called "life garbage" - every day from January to June.
This was down 710 tons per day on the same time last year.
Officials hailed this as a great achievement following the introduction of the waste separation trial in 133 residential communities.
It aims to reduce the quantity of garbage needing processing by requiring residents to put dry and wet waste into separate, color-coded trash bags and place these in different bins.
Specialist companies use wet waste to make fertilizers and other products, removing it from the city authorities' processing chain.
"We always saw an increase in life garbage in recent years - this is the first time the quantity has fallen," said Liu Weiguang, a bureau official.
"Over the year, we are confident of fulfilling the target of reducing life garbage by 5 percent from last year."
Extension plan
Officials said Shanghai will further refine trash classification on major garbage - including kitchen waste, construction waste and large items - and perfect a market-based trash collection and recycling network.
The household trash separation program will be extended to 1,009 communities by the end of this year and all communities with property management by 2015, as well as universities, restaurants and star hotels.
According to officials, separating dry and wet waste is vital as 60 percent of local household garbage is kitchen waste and fruit peel.
Wet garbage reduces the efficiency of trash burning.
Shanghai plans to reduce the amount of rubbish that needs processing by 5 percent annually from this year and realize at least a 20 percent reduction by 2015 and a 50 percent drop by 2020.
A national plan to cut trash says enterprises and individuals should pay trash processing fees.
A charging scheme is under consideration by the city government, the bureau said.
According to the national plan, cities should process in an environment-friendly way 80 percent of domestic waste by 2015.
By 2030, all cities should achieve a 100 percent of quality treatment of domestic waste and realize a sorting mechanism of domestic waste.
Shanghai generated 7.1 million tons of non-industrial garbage in 2009, 4.7 percent more than in 2008.
