With the increasing awareness of environmental protection and the improvement of garbage disposal technology standards by governments around the world, the drawbacks of traditional waste treatment methods such as landfill, composting, and incineration have become increasingly prominent. Landfills occupy a large area of land. The amount of composting is small and the efficiency is low. The incineration is prone to secondary pollution, especially the highly toxic carcinogen dioxin, which hinders its development. Therefore, the development of adaptable, efficient and clean waste treatment technology is the key to solving the problem of urban waste, and it is also the trend of developing waste treatment technology in countries around the world. The waste pyrolysis gasification technology can effectively overcome the problem of tail gas pollution caused by waste incineration while achieving garbage harmlessness, reduction and resource utilization, thus becoming an emerging waste treatment technology with great development prospects.
The waste pyrolysis gasification technology is called the third generation waste treatment technology. In the early 1990s, France, the United States, Britain, Germany, Switzerland, Japan and Sweden participated in the development of this technology, and it was adopted in developed countries in the mid-to-late 1990s. Unlike other technologies, Haiqi Pyrolysis Gasification Technology can handle both domestic waste and solid waste such as industrial waste and sludge.
