There are generally three sources of scrap steel in China: firstly, the self-produced scrap steel produced by steel enterprises during the production process. At present, the steel yield rate of steel enterprises in China is around 95%, and the corresponding self-produced scrap steel accounts for 5% of the steel production. The second is the processing scrap steel such as corner scraps generated during the production process of industrial and mining enterprises.

Metal refers to substances with special luster, good conductivity, thermal conductivity, certain strength and plasticity, such as iron, copper, aluminum, etc. Elements with metallic properties are called metallic elements, and materials formed from or mainly composed of metallic elements and possessing general metallic properties are collectively referred to as metallic materials.

The research and development on the resource utilization of waste LCDs in China is relatively late, with a short time and limited content, resulting in a lack of effective solutions and processing for waste LCDs, which makes it impossible to carry out large-scale recycling and utilization. With the increasing emphasis on the research of waste LCD resource utilization, progress has been made in the resource utilization of waste LCD displays in China for a long time. Researchers are constantly solving the processing problems to promote a greener, more cost-effective, and environmentally friendly entire resource utilization process, with good economic benefits for by-products.
