Its material flow process is that, mining resources flow in the production process as raw materials, and then products made from raw materials access to trading market.
After purchased and used by consumers, waste materials changed from products are released to the environment, while those generated in the production are directly discharged to the environment[4].
This industry converts waste materials generated during production and utilization into reutilizing resources and products, including two processes, firstly, wastes are converted into renewable resources, then renewable resources are processed into products[5].
