Garbage disposal faces difficulties, incineration and landfill is difficult to continue

Recently, the secretary of the Hubei Xiantaoyuan Municipal Party Committee was dismissed because the masses have resisted the construction of a new domestic waste incineration plant since June, and this person has been ineffective in dealing with mass incidents. “Garbage Besieged City” has become a national problem. In the current cognitive scope of the government and experts, the construction of waste incineration plants is an inevitable option, but the burning of strong carcinogens has become common sense. Since April this year, there have been Zhejiang Haiyan. A number of residents protested against the garbage incineration project in Ningxiang, Hunan, and Zhaoqing, Guangdong.

Difficult to burn, landfill is difficult to continue

"Garbage" is eaten. "Pulping and building materials "spit it out"" Li Yuanxing, chairman of Huaao Environmental Engineering Co., Ltd., responsible for environmental sanitation and garbage transfer in the high-tech zone, contacted the reporter and went to Liangshan to visit Ren Xianjun team on August 25th. Pilot production line for research and development. Another company in the same industry, Jinya Environmental Protection Co., Ltd., and Guangzhou Xinya, the chairman of Ren Xianjun, jointly established a project company to promote this new technology nationwide.

In the torrential rain, a team of people Ma Haohao came to Liangshan. Here, three teams from the United States, Guangzhou, and Shunde in Guangdong were met. This project was made public, but the influence has spread to both at home and abroad. Although Ren Xianjun is somewhat exhausted, it is difficult to hide his excitement: "In the past two months, nearly 100 institutions and units have visited. In Qingdao, the 200-ton/day demonstration project has been launched. Beijing Zhongrui, Guangdong Shunde 300 tons/day treatment The project has signed a framework agreement."

The way the Ren Xianjun team works with local governments is also quite novel. Each city has a landfill, which not only occupies a large amount of land resources, but also leaks of waste liquids, which may cause groundwater pollution. Ren Xianjun’s new technology can dig up the landfilled waste and recycle it all. The location of the burial site is built into an environmental protection industrial park, and the pulp, building materials, and plastics separated from the garbage are further processed.

“A beautiful world without garbage” is the dream of Ren Xianjun for many years, and it also makes all visitors feel excited. Peter from the Las Vegas Waste Disposal Company told: "In contrast, the US's waste treatment technology is relatively backward. Before the landfill is manually and mechanically sorted, the resource utilization rate is only 25%. We understand This new technology to China is specially visited and hopes to land in the United States as soon as possible."

Meng Fanli, the person in charge of environmental protection in Jinan, said that the garbage disposal methods in developed countries are mainly landfill and incineration. The United States has a wide geographical area and is mainly landfill. The Japanese site is small and is dominated by incineration. Because the Japanese households have strictly classified the garbage, materials such as plastics that are prone to produce dioxin will not enter the incinerator, and the burning is less harmful. China's domestic waste is basically not classified. There is no other better treatment before. Waste incineration, which occupies less land and can generate electricity, is considered to be better than landfill.

However, the harm caused by incineration has caused great concern to environmentalists and the general public. Zhao Zhangyuan, a researcher at the Chinese Academy of Environmental Sciences, recently publicly stated that Erying is a primary carcinogen that no one can deny. No matter how good your emission control is, it will always exist and will remain in the human body for decades, even in In countries where garbage is strictly classified in Europe and Japan, high cancer-prone areas have emerged around incinerators.

Break through and re-recognize the "garbage industry"

Li Xingyuan has been engaged in environmental sanitation and garbage transfer work in Jinan High-tech Zone for many years. He has also studied many new garbage disposal technologies at home and abroad. He saw a bag of cleaned and dried pulp, which is completely beyond his recognition. Know: "The government has subsidies for the waste treatment industry. As long as it can be disposed of well, it is magical to treat the garbage completely."

"This is the root of the problem. Others regard garbage as a harmful substance. In our opinion, natural materials must be useful. Every substance comes to the world is useful. Garbage is just a misplaced resource." I have just done a waste project analysis report for a provincial capital city. The city has an annual output of nearly 10 million tons of garbage. “Our project has enough confidence to open up the market because 1.5 million tons of waste plastic is buried in this 10 million tons of garbage ( Chemical fiber), 1.5 million tons of pulp and 1 million tons of high-quality organic fertilizer. Only these three products will create a large enterprise group with an annual output value of 8 billion yuan and a profit and tax of 4 billion yuan."

The reason why there are a large number of environmental protection and environmental enterprises take the initiative to come to the door, they are interested in the economic benefits that the project itself may bring. Waste processing products such as organic fertilizer, pulp, plastics, etc. have been tested by authoritative departments and meet relevant standards. Pulp can be directly sold to carton factories for outer packaging cartons, cardboard and corrugated paper; lightweight plastics can be sold directly to waste recycling companies as waste plastics, sold as raw materials for sale to heavy oil processing plants for cracking or oil production, or as plastic masterbatches It is sold to medium and low-grade plastic products production plants; rigid plastics are foamed and can be made into building pipeline insulation materials, or directly crushed, and made into ordinary building hollow bricks with sand, broken glass and ceramic mixed cement.

“The profit per ton of raw garbage can reach 200-300 yuan. This is the active attraction of the waste processing industry to capital. Those waste treatment projects that rely on government subsidies to survive, and the garbage pollution tumors of those besieged cities will Will inevitably be ruthlessly eliminated." Ren Xianjun said.

It is understood that Huaao Environment is currently communicating with government departments, new technologies are expected to land in Jinan High-tech Zone, and the relevant person in charge of Jinan City Management Bureau is also investigating this new technology.
