Necessity of waste resource utilization

           With the rapid development of society, the amount of waste generated is increasing at a rate of about 10% per year, and various types of solid waste have produced a large number of pollutants that threaten people's health. "Garbage and solid waste siege" has become a public problem facing cities. With the waste of resources, carbon dioxide emissions and environmental pollution, the country's goal is to make solid waste and garbage harmless, low-carbon and resource-based. The harmless recycling of various types of waste is one of the best ways to reduce pollution and greenhouse gases such as carbon dioxide. The rational and effective development and utilization of various types of urban waste and the harmless transformation of plant resources are indispensable conditions for building ecological and environmental protection. Today, with the increasing scarcity of resources, especially the innovation of urban mineral resource recycling and treatment technology, improving the recycling rate of waste resources has become an urgent problem to be solved in building my country's low-carbon environmental protection and sustainable development.
