The amount of garbage generated by Chinese cities is staggering. In Beijing, for example, more than 2,600 tons of food waste were generated per day in 2018, double the daily output of 1,200 tons in 2014, and with a four-year compound growth rate of 20 percent.

Large kitchen waste treatment equipment 10 enterprises leading brand", Changsha Leibang environmental protection 10 years deep plowing environmental protection industry, kitchen waste treatment equipment leading brand.

Currently, China's food waste treatment technology mainly includes traditional treatment technology and resource treatment technology. Among them, the traditional treatment technology mainly includes landfill and incineration methods, and the resource treatment technology mainly includes aerobic composting, feed treatment and anaerobic fermentation.

In resource treatment technology, aerobic composting is the process of using microorganisms to degrade organic matter in food waste, including aerobic biological treatment and composting. Food waste is rich in organic matter, with moderate water quality and uniform nutrient composition, which is very suitable for microbial growth. Therefore, the microorganisms in the food waste grow and multiply naturally under a certain accumulation state, degrading the organic matter and generating stable humus-rich organic fertilizers. It is also the main direction of future kitchen waste treatment.
