The world's first set of 10,000-ton coal-based degradable materials project was completed and put into operation

On the 19th, it was learned that the 50,000 tons/year polyglycolic acid (PGA) degradable material demonstration project of China National Energy Group Yulin Chemical was officially completed and put into operation, opening up all production processes, marking the world's first set of coal-to-polyglycolic acid degradable materials demonstration project to achieve industrial production

Polyglycolic acid degradable materials have many advantages such as full biodegradation, high biocompatibility, high mechanical properties and high barrier properties, and can be completely harmless degradation in soil, seawater and other environments

In the global environment of successive "plastic restrictions", "plastic bans" and increasingly stringent environmental protection requirements, polyglycolic acid degradable materials are ideal alternatives to disposable plastic products, which can be widely used in disposable plastic bags, lunch boxes, straws and other food packaging fields, and can also be used for bridge plugs, fracturing balls and various temporary plugging materials required for oil and gas development, as well as medical surgical sutures and bone scaffold materials, providing a new path

The coal-based biodegradable materials produced by the project adopt the independent intellectual property rights technology of the National Energy Group, and all the key equipment has been localized

On the basis of the successful demonstration of the project, the National Energy Group said that it will accelerate the technical and economic demonstration, further extend the industrial chain, form a series of coal-based biodegradable materials with complete functions and varieties, and promote the transformation and development of
