  • Existing waste disposal methods mainly have the following defects and problems:
  • Incineration of waste will produce 20%-25% of the burning residue.
  • the prior art usually treats the residue in a harmless manner and then extrudes and fills it, which still takes up a lot of land. Because the residue contains heavy metals and other harmful substances, the processing technology is high, the processing equipment is complicated, and the treatment cost is high. If some incineration plants cannot completely treat the residue in a harmless treatment or incomplete treatment, this will cause soil and groundwater. Serious pollution.
  • Incineration of waste requires high investment.
  • An incineration plant that processes 300,000 tons of waste a year needs to invest 320-350 million yuan, mainly for the purchase of large-scale land and complex equipment, especially for the harmless treatment of exhaust gases.

Long-term pollution of groundwater resources, some areas will be built on the beach, causing damage to offshore waters and marine life. Landfill not only wastes a lot of land resources needed for landfill, but also causes environmental pollution. Because land pollution is concealed and lagging, it has accumulation and unevenness. The most important thing is that it is irreversible, such as heavy metals. Difficult to degrade leads to a process in which land pollution is basically not completely reversed, and organic pollutants also take a long time to degrade, which brings endless troubles to future generations. At present, many developed countries have banned landfill waste. The competent authorities and technical experts at all levels of the Chinese government believe that this way of dealing with garbage cannot be sustained, but it has not yet found a way to prevent environmental pollution and to replace it with an efficient and simple treatment.
