Recently, many second - and third tier cities across the country have invested hundreds of millions of yuan to build waste to energy power plants, which has something to do with the two intensive national support policies this year. However, waste incineration power generation is widely controversial due to its large initial investment, high operation cost and easy pollution. Experts believe that from the perspective of waste treatment and utilization, waste incineration power generation is only the primary stage of its resource utilization, and more clean and efficient utilization methods need to be developed in the future

1.

a nationwide wave of investment and construction of

garbage power plants

on July 2, Qinhuangdao, Hebei Province. The waste incineration power generation and heat supply project with a total investment of 450million yuan has been officially put into operation. The project is designed to process 1000 tons of domestic waste per day, and can provide heat to local residents and industrial enterprises with a load of less than 5000kg

june 30, Kunming, Yunnan. The 110kV waste incineration power plant in Kunming Airport Economic Zone was put into operation and electrified, with a total investment of more than 300 million yuan and an area of more than 100 mu

june 14, Shihezi, Xinjiang. The project of the first waste to energy power plant in Northwest China, located in the city, has invested more than 200million yuan, with a daily treatment capacity of 800 tons of domestic waste. It will start construction as soon as the third quarter of this year

in June, Chongqing. It is reported that the second waste incineration power plant will be officially put into operation

may 25, Yongkang, Hunan. As a key project in Hunan Province, Yongkang waste incineration power plant has a total investment of 270Million yuan, covering an area of more than 60 mu. It began to generate electricity in August; On the same day, the foundation laying ceremony of Fuxin Municipal solid waste power plant was held

may 22, Zigong, Sichuan. The municipal domestic waste incineration power plant covers an area of more than 90 mu, with a total investment of 350million yuan

may 21, Haikou, Hainan. The overall completion acceptance of the municipal waste incineration power plant project. The power plant covers an area of 90 mu, with a project investment of 466million yuan. The construction began in 2008, and the ignition test run was conducted at the end of May 2011

may 11, Chuzhou, Anhui. With a total investment of RMB 287million, the first municipal solid waste incineration power generation project in the city has been signed

may 8, Chongqing. Sanfeng kawanta Environmental Industry Co., Ltd. of the city has built the world's largest garbage incinerator assembly base after three years, with a construction area of 13000 square meters and an annual assembly capacity of more than 60 sets of garbage incinerators

...

the above are just the tip of the iceberg of crazy investment and construction of waste to energy power generation projects across the country. Recently, especially in June, many second - and third tier cities have invested hundreds of millions to build waste to energy power plants, setting off a wave

and this does not seem to be the case. At the beginning of this year, North China Electric Power University released the investment analysis report on China's urban domestic waste industry (2012). The data showed that from 1998 to March 2012, the cumulative investment in China's waste incineration power generation project market was 146.9 billion yuan, a total of 449 projects. Among them, the market investment of Guangdong waste incineration power generation project is 27.2 billion yuan, accounting for 18%

Zhang Yi, President of Shanghai Environmental Engineering Design and Research Institute and Shanghai Environmental Sanitation Engineering Design Institute, said here that by 2015, 384 waste to energy power plants will be added in China, and the daily incineration capacity will reach about 310000 tons

subsidies become the main income of waste power plants

why does such a large-scale investment flow to the field of waste incineration? According to the analysis of some experts, this has something to do with the state's policies to support waste to energy power generation in recent years, and the subsidies given by local governments to cover tax, financial and other support

the two supporting policies intensively introduced this year have given good information to the field of waste incineration power generation. It is reported that on April 10, the national development and Reform Commission issued the notice on improving the price policy of waste to energy power generation if it is not available. The notice clearly stipulates that waste to energy power generation implements the national unified benchmark price of 0.65 yuan per kilowatt hour for waste to energy power generation, and the part of the price of waste to energy power generation higher than the benchmark price of local desulfurization coal-fired units is shared by two levels

on April 19, the 12th Five Year Plan for the construction of national urban domestic waste harmless treatment facilities issued by the general office of the State Council clearly stated that by 2015, the capacity of national urban incineration treatment facilities will reach more than 35% of the total capacity of harmless treatment. During the 12th Five Year Plan period, the total investment in the construction of harmless treatment facilities for urban domestic waste in China will reach 263.6 billion yuan

these policies can be said to reassure the waste incineration power generation enterprises. Xuchongqing, deputy director of the Energy Research Institute of Shandong Academy of Sciences, said in a media interview that a very important reason for the rapid emergence of waste incineration power generation enterprises in recent years is that the state pays more and more attention to environmental protection and has more and more preferential policies

it is learned that the construction cost of waste incineration power plant in the early stage is high, and it is generally led by the government; In the later stage, due to immature technology and inadequate waste classification, the operation cost is high, which becomes one of the burdens of waste incineration power generation

according to the public data, the main sources of cost compensation and profit of waste incineration power plant are waste treatment fee subsidy and electricity price income. The so-called garbage treatment fee subsidy means that the government will give a certain amount of subsidy for each ton of garbage treated. The standards of local governments vary, ranging from 50 yuan to 200 yuan per ton

previously, some media quoted insiders in the industry as saying that × Take the first incineration power plant as an example. The average power generation per ton of garbage is 360 degrees, up to more than 400 degrees, and the annual electricity price reaches more than 50million yuan, which is enough to make the revenue and expenditure of the garbage power plant balanced

it is not a healthy development model for waste to energy power generation projects to rely too much on government investment. National financial subsidies should be symbolic and encouraging. Some insiders who declined to be named said that

however, according to lixiuguo, a senior researcher of the Chinese Academy of Sciences, waste to energy power generation is now in the initial stage of development and needs government policy and financial support. Both wind power and solar power now need state subsidies because their costs are higher than thermal power. He explained that the current technology of waste to energy power generation is not mature, and it is far from reaching the stage of independent profitability. It is understandable that the government should give appropriate subsidies

turning waste into treasure or secondary pollution is controversial

compared with the high construction and operation costs, the secondary pollution caused by waste incineration power generation is more difficult, and public opposition has become a stumbling block for many waste incineration power generation projects

according to media reports, the waste to energy power plant in the west of Qinhuangdao ran aground due to public opposition. It is understood that the project is planned to invest 220million yuan. It was originally planned to be completed in August 2011, but it was stopped at the end of 2010 due to resistance from tens of thousands of villagers and 37 village committees around. At present, this disturbance has evolved from the initial environmental protection incident to a judicial lawsuit. The local villagers twice applied to the Ministry of environmental protection for administrative reconsideration and sued the environmental protection department of Hebei Province

such cases are not new in the field of waste incineration power generation. Dioxins and heavy metal ions produced by waste incineration make people pale, which is also attributed to the low quality of waste in China by the owners of waste incineration

in China, people have not yet formed a good habit of waste classification. Lixiuguo told that waste classification is a piece of cake for every family, but for waste incineration power generation, it can reduce a lot of costs

liyujun, director and associate researcher of the environmental economy and Management Research Office of the Institute of urban development and environment, Chinese Academy of Social Sciences, focused on waste management research. He talked about waste classification and cleaning methods: when the lower collet was raised, he told the South: unlike foreign countries, most domestic waste in China has high moisture content, low calorific value and complex composition, and the cost is relatively high when used for waste incineration power generation. She said that waste incineration needs to add a lot of fuel to support combustion, which greatly increases the cost of waste treatment and power generation

some experts believe that the key to the problem lies in the marketization of the waste incineration industry, starting from the front end of waste treatment. Only with the improvement of the marketization of the front end of waste treatment, can it be possible to collect and display waste in real time from time to angle, mobilize the enthusiasm of residents for waste classification collection and reduction, and promote waste classification and reduction, so as to ensure the high-quality supply of waste and reduce the pollution caused by waste incineration power generation

lixiuguo disclosed that in fact, the secondary pollution caused by waste incineration power generation is gradually improving technically, the emission of dioxins and other harmful and carcinogenic substances is decreasing, and even the most annoying heavy metals have degradation methods

4.

waste incineration power generation is only a transitional stage

lixiuguo told the south that in the past, the main means of waste disposal was landfill, and each landfill occupied hundreds of thousands of mu of land, polluting the soil. He explained that the waste contains a large amount of organic waste, which will decompose during landfilling, producing a large amount of methane, liquid and other substances that corrode the soil, affecting the living of surrounding residents

I think the most important thing is to change people's concept that garbage is not useless waste, but a resource that can be developed and utilized. Lixiuguo said that the heat from waste incineration is used to generate electricity, turning waste into a resource. From this perspective, waste power generation is better than landfill

in an interview with the south, lijinliang, an expert from the international cooperation center of the national development and Reform Commission, said that the highest level of waste treatment is resource utilization, and waste power generation is only one of the methods

lixiuguo agreed. Incineration power generation, a waste treatment method, is only a transitional approach, and it is the primary stage of waste resource treatment. Better technologies will certainly emerge in the future

lixiuguo added that there will be some differences in the composition of garbage in different regions, and the disposal and utilization of garbage should be adjusted to local conditions. The South has lush plants, abundant rainfall and more organic matter, while the north is different; The amount of waste produced in different cities is also different, and the corresponding most cost-effective treatment methods are also different. He said that this requires garbage disposal to be resource-based and energy-based. Each place should reasonably arrange waste treatment methods according to its own actual situation to maximize its utilization value

various categories of garbage

garbage in the current sense mainly includes three categories

first, domestic waste, in which organic matter is the main component, can be burned; The second is construction waste such as bricks and tiles, which is produced by the large-scale urbanization process and the transformation of shanty towns; The third is industrial waste. At present, China is faced with serious household appliance waste and old car waste, which contain a large number of rare elements

now the concept of urban mining is under heated discussion in the industry. This concept regards garbage as an artificial mineral for mining
