GRS certification is a global recycling standard. It covers renewable material content, production and marketing chain of supervision, social responsibility human rights system, environmental management system and chemical management system projects.
GRS certification aims to increase the use of recycled materials in products and reduce the hazards caused by elimination and production. The GSR certification of the global recycling and recycling standard was developed by Shiyou, and its ownership was transferred to the United States Textile Exchange on January 1, 2011, with more than 20% recycled material content. Products can apply for GRS certification, and products with more than 50% recycled material content can use the GRS label, which can be used in the company's product tag, product packaging, business card, website and other places.
The main component of neodymium iron boron magnet is praseodymium and neodymium metal. Praseodymium and neodymium belong to rare earth and have high value; NdFeB permanent magnetic material has excellent performance and is widely used in automobile, household appliances, wind power, consumer electronics and other fields. It is the most important type of permanent magnetic material in the market at present. In recent years, with the vigorous development of the electronic information industry, wind power and new energy vehicles, the demand for NdFeB is increasing, and the annual output of sintered NdFeB is also gradually increasing.
In the process of sintering NdFeB, a large number of scraps and magnetic mud and other wastes will be produced. At the same time, more and more electromechanical equipment containing NdFeB magnets will be scrapped, and a large number of rare earth permanent magnet wastes will also be produced. The content of rare earth elements in Nd-Fe-B magnet materials accounts for more than 30%, and the rare earth resources are non-renewable. Using economic and effective methods to recycle the rare earth metals in Nd-Fe-B waste can create high economic value, save resources and reduce environmental pollution.
