To Be a Leader in Resource Recycling

Shanghai CN Science and Technology Co. Ltd.
CN Technology has more than 20-year experience in treating three wastes, utilizing and developing resources and operating projects. Besides, CN has invested in energy-saving and environmental protection technologies and can effectively recycle industrial wastes into useful resources. Especially in the recycling, separation and purification of spent lithium batteries, CN can convert the spent battery materials into reusable high-performance battery materials and raw materials for other industrial production. CN is headquartered in Shanghai, equipped with a manufacturing and R & D base with a total area of over 700 mu in Chizhou High-tech Development Zone, Anhui Province.

Historical Evolution
Technology and Device R&D
In wastewater treatment, CN made innovative breakthroughs in developing suspended separation and oil-water separation technologies, winning the technology innovation fund of MOST and obtaining its own technical and intellectual property achievements; during this stage, CN has developed devices with its own patents such as CN liquid filter, CNO degreaser, CNJ metal recovery machine and others waste water and gas treatment, and engineering design and services. These featured products have been widely applied in industries including titanium dioxide, winning the Shanghai high-tech achievements transformation certificate.
Industrialization of Technological Achievements
Our company has made breakthroughs in developing technologies concerning separation, concentration, purification and un-oil of non-ferrous metal ions and obtained many achievements which are widely used in the metallurgical industry. The CN technical system has been continuously improved with technology in cleaning and recycling and abstracting industrial wastes and low-grade ores. Consequently, we form our core patent technologies and complete sets of production equipment to provide customers with overall treatment solutions.
Transformation from Equipment Technology to Production Operation
In addition to offering customized solutions and eco-friendly equipment for customers, CN invested a Solid Waste Disposal Site Base(0.2 million tons) in Chizhou, Anhui, to industrialize our own technology and equipment and form our own production capacity. In Phase I, this base processed 50,000 tons of solid waste annually, mainly producing nickel, copper, cobalt and other metallic compounds.
Production of Solid/ Hazardous Waste Base (Phase One)
In 2014, Chizhou Solid/ Hazardous Waste Base (Phase One) was in trial with a capacity of 50000 tons/year. Besides, CN completed the share reform and cooperated with Zijin Mining Group LTD and Jiangxi Copper Group; our company was rewarded as the advanced unit in "433" key project by Chizhou municipal party committee and government. In 2015, CN was licensed to operate hazardous waste, breaking the barriers of trans-provincial operation of hazardous waste.
Starting Lithium Battery Recycling
As lithium batteries continuously develops, CN has strengthened R & D in the utilization of non-ferrous metal resources. As for NCM lithium batteries, CN developed the recycling technology of spent cathode materials and invested in a recovery project to recycle 6000-ton lithium battery cathode materials. In treating hazardous waste, our company increased the R&D in pyro-metallurgical project (Phase II). In 2019, our company was licensed to operate 0.2 million tons’ hazardous waste. Additionally, the oxygen-rich side-blown project of Phase Two Hazardous Waste Base (0.15million/year) was successfully debugged and entered into trial.
