GEM's main business belongs to the comprehensive utilization of waste resources and the new energy industry, forming a dual track driven business model of "urban mining+new energy material manufacturing". In the field of urban mining, GEM recycles and utilizes waste power batteries, electronic waste, scrapped cars, waste plastics, and nickel cobalt lithium tungsten strategic resources, mainly remanufacturing nickel cobalt lithium tungsten, rare resources of gold silver platinum palladium, ultrafine cobalt nickel tungsten powder materials, and modified plastics; In the field of new energy, GEM manufactures ternary precursors, ternary cathode materials for power batteries, and cobalt tetroxide materials for 3C digital batteries, making it a leading enterprise in the world's new energy supply chain.
GEM has led the establishment of national innovation platforms such as the National Engineering Research Center of Waste Electrical and Electronic Equipment (WEEE) Recycling, the National Energy Metal Resources and New Materials Key Laboratory, and the National Enterprise Technology Center. It has also established a systematic technical and intellectual property system for waste recycling, resource regeneration, and material remanufacturing in China. It has applied for 3767 patents globally, led the formulation/participation of 475 national and industry standards, and achieved a number of major scientific and technological achievements. It has won 2 National Science and Technology Progress Awards and 10 Provincial and Ministerial First Prizes.
