The entry-exit inspection and quarantine authorities should carry further research and enhance the implementation of the national compulsory standards for iron and steel scraps;

Investment in China's iron and steel scraps industry has good prospects

Reviewed the survey of domestic steel scraps in 2007, the consumption situation of iron and steel scraps, the changing situation of steel scraps import.

Rising prices and reduced quality for scrap are increasing concerns about the future supply of quality steel in the world.

The application of manganese mineral filter technology to the iron and manganese removal from the steel wastewater recycling treatment has been studied.

On the condition of guaranteeing the quality of sinter and stability of productive process, the sintering process of adding ferruginous waste such as steel-making slag, iron oxide scale and dust separately is analyzed.

By means of materials design in composition and microstructure,a glass-ceramics was prepared with iron and steel slag up to 55～60 mass %.

The paper introduces in brief the present status of recovery and utilization of China's scrap iron and steel resource, and the demand of scrap iron and steel resource in iron and steel industry, forecast demand of scrap iron and steel resource in future according to the three different models, puts forward problems and policy suggestions on sustainable utilization of scrap iron and steel resourc
