Industrial waste refers to solid waste discharged from machinery, light industry and other industries during the production process. For example, machinery industry cutting debris, grinding debris, waste sand, etc., the activated carbon slag in the food industry, the brick, tile, gravel, concrete crushing garbage in the silicate industry and construction industry are mainly treated in the following ways. Species: Landfill: Less landfill waste investment, large processing capacity; technical requirements are not high. However, its permanent footprint is large and the potential for pollution is high. In developed countries such as the United States, there have been incidents of pollution caused by landfills for decades. Composting: Treating garbage by composting can turn garbage into organic fertilizer. However, this kind of waste fertilizer has low fertilizer efficiency, limited sales, and little room for development. Incineration: Incineration of waste has the most thorough advantages of recovering heat and reducing waste. At present, incineration is the most reasonable way to destroy.
