Although the development blueprint has been formulated, the great development of waste power generation faces multiple problems

a recent visit found that after nearly 20 years of development, the equipment and technology of waste incineration power generation continue to mature, but the treatment capacity of waste incineration power generation still cannot match the amount of domestic waste produced by reprocessing through sorting plants in China. In order to turn a large amount of waste to be treated into treasure, it is urgent to establish more waste power plants. However, problems such as low price bidding, difficult garbage classification and decentralized management are seriously hindering the further development of the industry

2/3 cities are troubled by "garbage siege"

at present, the most important way to solve domestic waste in most cities in China is landfill. With the rapid increase of urbanization rate, the amount of urban garbage has increased sharply, and the pressure of garbage treatment everywhere is increasing. Taking Shanghai as an example, more than 28000 tons of domestic waste are produced every day, and 80% of the waste needs to be landfilled

coincidentally. "Shenzhen produces 18000 tons of garbage every day, buries 6700 tons, and more than 10000 tons of garbage can't be treated. Now the Xiaping solid waste landfill and the Laohukeng landfill in Bao'an District have been filled." A relevant person in charge who just came back from the construction site of waste to energy power generation in Shenzhen said

according to the interview, at present, the comprehensive waste landfills in Shanghai, Shenzhen and other cities have already become saturated. According to the "13th five year plan" for the construction of national urban domestic waste harmless treatment facilities, it is estimated that China will have more than 400 million tons of waste to be treated by 2020. A large amount of garbage piled in the open air or simply landfilled will not only cause environmental pollution, but also endanger human health

according to the latest data, at present, China produces up to 2.5 billion tons of garbage every year, accounting for 1/4 of the world's total. With the continuous progress of urbanization, the amount of garbage generated will increase at an annual rate of 8% - 10% for a long time (some cities such as Shanghai have reached 15% - 20%), exceeding the garbage growth rate of 6% - 10% in European and American cities. The accumulated stockpile of urban domestic waste has reached 7 billion tons. Nearly 2/3 of the cities are surrounded by garbage belts, and the accumulated garbage storage area is more than 750000 mu. One quarter of the cities have no suitable place to stack garbage. It is estimated that the national annual loss caused by garbage is as high as 30billion yuan

has planned the "big goal"

"at present, it is necessary to accelerate the development of waste incineration power generation to solve the environmental problems of 'waste besieging' on urban development." A person in charge of building a waste incineration power plant told me

it is reported that in order to effectively solve urban waste, the state plans to invest 263.6 billion yuan in the construction of urban waste treatment facilities during the 13th Five Year Plan period. According to the 13th five year plan for the construction of harmless treatment facilities for urban domestic waste throughout the country, by the end of 2020, municipalities directly under the central government, cities specifically designated in the state plan and provincial capital cities (built-up areas) that meet the conditions should achieve "zero landfill" of primary waste. The state proposes to gradually close landfills and rebuild waste incineration plants, and the waste incineration treatment capacity will reach more than 50% by the end of 2020. It can be seen that the waste incineration power generation industry will enter a stage of rapid development

it is reported that China's waste incineration industry is still in the initial stage of industrial development. The waste incineration power generation industry started in 2000. Waste incineration projects have been piloted in Zhejiang and Guangdong, and then gradually developed inland from point to area. By about 2010, garbage incineration power generation equipment and technology have overcome domestic acclimatization, and more than 100 garbage incineration power plants have been built nationwide. "After nearly 20 years of development, the technology of waste incineration power generation industry is relatively mature. Therefore, during the 13th Five Year Plan period, the state mainly promoted waste incineration power generation and required county-level cities to build waste incineration power generation projects. It is estimated that there will be 100 construction projects." An industry expert who declined to be named said to

many problems need to be clarified

although waste incineration power generation has formulated a "blueprint" for development, some problems faced by the industry development still need to be clarified - low price bidding, cumbersome approval, difficult waste classification, decentralized management and other issues have become the main reasons restricting waste incineration power generation

an unnamed owner of waste incineration power generation disclosed to: "Vicious competition among enterprises is serious. Many enterprises promise preferential conditions to the government in order to get the waste incineration power generation project, such as higher construction standards and lower waste treatment fees. However, after obtaining the project franchise rights from the developed special plastics and degradable plastics, they either resell the project to other companies or individuals, or coerce the government to increase the domestic waste treatment fees."

according to the data, in recent years, the bidding of waste incineration power plants has constantly refreshed the lower price limit. For example, on December 21, 2017, Anhe launched a coal heating granulator in Northern Shaanxi. The unit price of waste disposal fee won the bid for the waste incineration power generation BOT project in Taihu County, Anhui Province was 15 yuan/ton, which once again set a new low price limit of 18 yuan/ton for Chongqing Sanfeng in 2015

"although the social benefit of waste incineration power generation is greater than the economic benefit, the general waste incineration treatment price is about 76 yuan/ton, such as the phenomenon of more than 10 yuan/ton in recent two years is not quite reasonable." The above-mentioned person who did not want to be named said frankly to

Zhang Dayong, Deputy Secretary General of China biomass alliance, said in an interview earlier that low-cost competition has become a persistent disease restricting the waste incineration power generation industry. "It is suggested that the government should standardize the entry standards for waste to energy power generation projects. The state should formulate a reasonable bidding mechanism in combination with the actual construction and production and operation of waste to energy power generation projects, so as to form a virtuous circle of competition."

in addition, Yuanhuaihua, deputy general manager of Xinhongyuan Technology Co., Ltd., said to: "In the approval stage of the construction of waste incineration power generation projects, there are cross sectoral issues that need to be sealed by different departments. There are great differences in the approval of each province and city, which is very cumbersome. I hope to clarify the management department of waste incineration power generation.

in addition, the rapid and healthy development of waste incineration power generation also needs to improve the policies, laws and regulations of waste incineration power generation. At present, although China has made provisions on waste classification in some legal provisions, but There are many principled provisions on the provision of green channel services, but few substantive and operational provisions. For example, the classification of domestic waste is mentioned in the law on the prevention and control of environmental pollution by solid waste and the measures for the administration of urban domestic waste, but there are no clear provisions on how to classify and the punishment for not classifying

"at present, the collection of domestic waste is in the charge of relevant departments such as streets, neighborhood committees, property management, etc., the cleaning, transportation and treatment of waste is in the charge of the environmental protection department, and the medical waste is in the charge of the environmental protection and health department. In the chain of waste treatment industrialization, the functions of various departments have not yet formed a synergy, so it is difficult to cooperate in waste classification." The above unnamed person said, "this is not conducive to industrialized management, market development, improving the scientific and technological content of waste treatment, reducing costs, improving efficiency, and realizing the transfer of decentralized waste treatment to centralized industrialized treatment and disposal. It is suggested to improve the comprehensive coordination mechanism of waste incineration and power generation."
