Now that the process of urbanization is accelerating, people's living standards are also improving, and at the same time, more and more domestic waste is brought. According to statistics, the annual output of urban waste in my country is about 200 million tons. Faced with such a huge amount, if this urban waste cannot be effectively and harmlessly treated, it will cause serious pollution to the environment.

At present, municipal solid waste generally adopts three disposal methods: landfill, incineration, and composting. Metal substances are separated and reused, and the rest of the garbage can be made into RDF high-density particles for resource regeneration.

Municipal solid waste(MSW), also known as municipal solid waste, refers to the solid waste generated in the daily life of urban residents or in the activities of providing services for urban daily life. Municipal waste contains a large number of high calorific value components, and the preparation of RDF from domestic waste is a good solution for the recycling of domestic waste. The process of preparing RDF fuel from domestic waste is through crushing, sorting, drying, and adding additives. After molding, Refuse Derived Fuel (RDF) has the characteristics of high calorific value, with a calorific value of 5500Kcal/kg, stable combustion, easy transportation, easy storage, low secondary pollution, and low emissions of dioxins.

Refuse-derived fuel (RDF) processing and production technology first crush domestic waste, sort out combustibles, then add additives to dry, and finally extrude it to make granular RDF fuel. With the increasing shortage of energy in recent years, the research and innovation of new technologies to improve the efficiency of dryers and the application of biomass energy have been vigorously developed in China, and new types of garbage dryers have been rapidly promoted and popularized. The trend of environmental protection will continue to continue, to meet the needs of sustainable green development, and the future solid waste drying equipment will usher in the peak of development.
