Deadlock In The City Garbage Treatment: Progress In Waste Classification Problems

Garbage dispute Recently, the environment caused by the waste incineration controversy

, has become a hot topic of China's public environment. Over the past year, Guangzhou, Shenzhen, Panyu, Nanjing, Shanghai and Beijing and other cities all have varying scale outbreak of mass incidents, some people openly expressed their concerns about incineration plant affect the living environment. However, relevant government departments to deliver the message that waste incineration will be the new trend of China's large cities waste. Beijing, for example, early in the year "

Two ", The 283 deputies of the waste motion, directed at the critical situation in Beijing and waste disposal dilemma. After the Beijing municipal government through research to reach a consensus, clearly stated," speed up the Solid Waste Incineration and comprehensive treatment plants. "According to the plan Beijing will invest 10 billion yuan in 2015, the construction of 40 waste disposal facilities, including nine incineration plant. then, has been operating for a year in addition to the high security outside Tuen incineration plant, incineration plant Aso Wei, Beijing South Incineration Plant, Dong Village, incineration and incineration plants Liulitun, North heaven incineration plant, Nangong incineration plant, incineration plant and the beam, Shunyi District, home incineration plant will be gradually put into operation, the waste treatment capacity will reach 8,200 tons per day garbage incineration ratio from the current 2% to 40%.

Behind this project is to enhance the speed of the Beijing Municipal waste disposal capacity of the serious lag. Statistics from the municipal government of Beijing's garbage in 1990, total less than 200 tons, in 2008 soared to 6.72 million tons, 18,400 tons daily. If according to the present rate of about 8% a year continued to increase, in 2012, Beijing garbage output will reach 9.14 million tons in 2015 to reach 11.52 million tons, daily average of 30,000 tons. At present the city a total of 23 municipal solid waste facilities, the design daily capacity of 10,400 tons, the actual capacity has reached 17,400 tons per day, the average rate of 67% overload.

All of China's situation is similar to Beijing. According to statistics, the country of trash in 1981 was about 30 million tons, to the rapid growth in 2004 was 1.6 million tons, annual growth rate of about 7% to 10%, and GDP growth rate of roughly the same.

Follow-up processing power because of lack of the garbage if you do not burn, it only into the landfill. Incredible to say, until 1993 when Beijing still take trash out of the city, open a simple stacking approach. Beijing 1994 built the first modern landfill, and finally have the ability to refuse to do sound processing. However, with rapid economic development, was soon faced with the situation not to be buried. Chen, director of Beijing Municipal Administration Commission, said in an interview: "Beijing is overloaded landfill operation, less than 5 years, 4 years no place to refuse to fill, so the construction of incineration plants for us stresses is necessary. "

However, waste incineration, if handled properly, will produce highly toxic substance dioxin, can not be said to be a perfect approach. The problem is, give all landfill will not last forever. Long-distance transportation of garbage from the economic terms is clearly very uneconomical, near the city landfill will take up valuable land resources, if the landfill technical imperfections, it will also generate a lot of harmful gases, and even pollute underground water. In recent years, the groups involved in landfill is an endless stream of events, social influence is also no less than incineration.

In the end is incineration or landfill? Stiff garbage problem in here. To break the stalemate, first priority is to reduce garbage.

Waste reduction

"To solve the general principle of municipal solid waste problem is 'five of' first priority is the reduction, to reduce garbage volume." Deputy chief engineer of Beijing Municipal Administration Commission, said Wang Weiping told BusinessWeek, "The second is resource , that is waste recycling. The third is the sound, such as landfill or burned. Fourth, the community, government and public enterprises must be involved. Fifth, industrialization, to encourage enterprises to operate.
