The state vigorously develops and popularizes the circular economy and advocates the recycling and efficient utilization of renewable resources and energy. The national development and Reform Commission made an overall deployment for the development of circular economy in the 14th five year plan. The development of circular economy emphasizes the recycling and efficient utilization of resources, and improves the utilization rate and recycling rate of waste materials and renewable resources. At present, China's resources and energy are limited. In order to ensure national resource security and promote social and economic development, vigorously developing circular economy has become an inevitable trend. It is also an important strategy for China's social and economic development during the 14th Five Year Plan period. Developing circular economy is not only to create a resource recycling industrial system, but also an important way to accelerate the "carbon peak, carbon neutralization" and build a harmonious green natural ecological environment.

In the process of developing circular economy, the waste material recycling industry is an important supporting point. The waste material recycling industry has developed rapidly in China for decades, but it is still in the stage of industry optimization. Although China's waste material recycling industry has developed rapidly, there are still problems such as low level of fine sorting, non-standard industry management Unequal resource quotation information and small plant recycling lead to environmental protection problems, which also leads to the low recovery rate and regeneration rate of waste materials and waste resources compared with European and American developed countries.

According to the statistics of the Ministry of Commerce, by 2019, the total amount of recycled resources such as waste steel, waste plastics, waste paper and waste rubber in China will be about 345 million tons, and the total amount of recycled resources will reach 900.38 billion yuan, which is far from the realization of the goal of "the total output value of China's resource recycling industry will reach 5 trillion yuan by 2025" proposed in the 14th five year plan for the development of circular economy, There is still a long way to go. In order to develop circular economy, we must first develop the waste material recycling industry. The waste material recycling industry is an important supporting point for the development of circular economy, truly realize the recycling value of renewable resources, maximize the utilization rate and regeneration rate of resources, completely change the traditional economic model and create circular social and economic development.

In the normal development of circular economy, it drives the transformation and upgrading of waste material recycling industry. Under the dual objectives of "carbon peak" and "circular economy", relevant departments pay more and more attention to the waste material recycling industry, put forward the new industry model of "Internet + recycling", and use modern high and new technology, Internet of things Big data upgrades and optimizes the waste material recycling industry, makes use of the sharing and co construction advantages of the Internet to build an online waste material recycling industry, improves the utilization efficiency and recycling efficiency of renewable resources, promotes the development of China's current circular economy, and makes the information of the waste resource recycling industry and the whole waste material recycling industry transparent, open Rationalization.
