In recent years, with the rapid development of China's economy and society and the continuous improvement of people's material living standards, the amount of food waste in China has been increasing, accounting for half or more of the urban domestic waste. The resulting waste resources and environmental pollution problems are also increasing. serious. As an important part of perishable waste, the amount of food waste generated reached 128 million tons. The management of food waste is of great significance for waste recycling, ecological environment protection and improvement of people's livelihood. How to effectively classify and properly dispose food waste has become an important issue in promoting the construction of circular economy and sustainable social development.

Under the guidance of the principles of "reduction, reuse and recycling" of the Circular Economy Promotion Law and "reduction, recycling and innocuity" of the Law on the Prevention and Control of Environmental Pollution from Solid Wastes, food waste in China is now widely used. The main treatment methods include landfill, incineration, crushing and direct discharge. In the process of treatment, composting, anaerobic biogas production and biochemical treatment are used as resources, and energy products are used as energy. Food waste is rich in nutrients, which makes it have great value in resource utilization, but there are also some difficulties.

In the process of collection, there are problems such as difficult collection, easy blockage, difficult retention, easy corruption, difficult transportation, easy corrosion, etc. Food waste treatment equipment The manufacturer is also prone to a series of environmental problems in the process of treatment. Ammonia, sulfide, leachate and other products and secondary substances will cause primary and secondary pollution to the atmosphere, water and soil. As the garbage classification work in China has just started, food waste is usually mixed with other garbage and treated by landfill, incineration and other methods, which not only easily brings potential harm to the ecological environment and the health of surrounding residents, but also causes waste of resources and methane emissions. An important source of greenhouse gas emissions.

Food waste treatment The cost will vary according to the treatment process. The corresponding government departments also provide subsidies, so the cost of food waste treatment is relatively acceptable. Of. But by contrast, Large scale kitchen waste treatment equipment Generally, the production cycle is long, there are many equipment production lines and supporting equipment. The actual effect is far less than expected. At present, there are small food waste treatment equipment on the market, which can be quickly installed in modules according to the needs of the site, and can also form medium-sized or large-scale food waste treatment production lines. The equipment can effectively reduce perishable kitchen waste from the source.
