Kitchen waste sorting and processing equipment

Pre sorting and treatment technology for kitchen waste

1. Pre sorting technology for household kitchen waste

In cities that have implemented mandatory classification of household waste, the separation rate of household kitchen waste continues to increase, and the end of pipe treatment system for household kitchen waste has gradually been improved. Based on the effectiveness of mandatory garbage classification in cities that have implemented it, and considering factors such as regional differences between southern and northern regions, coastal and inland cities, analyze their pre sorting processes.
Overall, the pre selection and treatment technologies for household kitchen waste management projects established in different cities and periods in China have not been unified. On the one hand, factors such as different dietary habits and varying levels of waste classification in different regions have led to different compositions of waste, requiring different combinations of pre selection and treatment technologies; On the other hand, different methods of organic matter resource utilization require different requirements for pre sorting techniques.

2. Pre sorting technology for kitchen waste

In 2010, during the special rectification of "gutter oil" and "garbage pigs", China strengthened the management of kitchen waste and launched the construction of pilot cities for the resource utilization and harmless treatment of kitchen waste. In addition, in the construction of pilot cities for ecological civilization and "zero waste cities", the resource utilization of kitchen waste has also been identified as a key construction project.
Overall, the pre sorting process technology for kitchen waste treatment projects in different cities and periods in China tends to be stable. On the one hand, the core equipment technology for pre sorting such as kitchen waste pulping and impurity removal machines and oil-water separation equipment is mature. On the other hand, the resource utilization of organic materials after sorting is widely applied through anaerobic fermentation, with the most successful cases and basically the same requirements for pre sorting technology.
