At the International Exhibition on Solid Waste Management Technologies and Equipment 2011, held in Beijing on the theme of “Green Energy Conservation and City Cleanupâ€, Yuan Lijun, Managing Director of China Energy Best Environmental Protection Energy Co., Ltd. (hereinafter referred to as “Zengeng Jiachengâ€) The reporter said: "We will invest 10 billion yuan in the next five years to create a pilot enterprise that will reduce, harmlessly, recycle, and stabilize the comprehensive disposal of municipal solid waste, so that more cities can benefit from it. The city is no longer surrounded by rubbish."
The environmental issue is a major topic that restricts the sustainable development of contemporary economic society. According to statistics, the global emissions of nearly 500 million tons of various types of garbage every year, China's major cities produce 150 million tons of live garbage every year, and is still rising at an annual rate of 8% -10%. Chinese cities lose as much as 25 billion yuan to 30 billion yuan each year due to waste. 97% of urban waste in China can only be disposed of simply by stacking or landfill. Garbage has become an ecological crisis that has swept the entire society.
Affected by the constraints of waste treatment technology, China's urban waste disposal is mainly sanitary landfill and incineration and composting. According to Yuan Lijun, sanitary landfilling is the most traditional treatment method. It takes up a large amount of land area, it cannot achieve waste reduction, and it also pollutes surface water and groundwater. Due to the limitations of capital and technology, there are quite a lot of “sanitationâ€. Landfill basically cannot meet the requirements of "sanitation". The composting method also cannot achieve the reduction of waste, and the market acceptance rate of compost products is low and cannot effectively compete with chemical fertilizers. It is basically not adopted in developed countries. The traditional method of incineration of primary waste, due to imperfections in its own technology, is not sufficient to burn, and it is easy to release dioxin-like pollutants. At present, it has encountered strong resistance from the people. He believes that in the long run, combustion is undoubtedly the best way to reduce the disposal of waste, and the use of heat energy generated by combustion is more in line with the current global environmental protection and low-carbon, resource recycling and sustainable use of this theme.
In order to make up for the current lack of domestic urban residents' waste classification awareness, Zhongneng Jiacheng adopts highly mechanized pre-sorting equipment to classify raw rubbish into four categories based on different channels for recycling, and to extract recyclable metals and plastics. Reuse. Experts in the industry believe that this technology is a benign way to make up for the worries of urban development, brings new ideas for the development of large and medium-sized cities, and is expected to become the primary choice for breaking through the “garbage siegeâ€.
Yuan Lijun emphasized in particular that “trash is a misplaced wealth.†With the increasingly tense coal-fired resources, the electrical energy resources brought by the integrated treatment of domestic waste will undoubtedly be a new energy growth point.
