Copper is widely used in electrical industry. In recent years, the development of Chinas economy has accelerated the replacement speed of electrical equipment and promoted the development of secondary copper industry. The recycling of used copper in China has also gradually become a hot research field.
At present, the total amount of copper used in China is about 100,000 tons per year. Due to the high degree of utilization of used electrical products, the amount of used copper used in our country increases year by year. According to statistics, the total amount of used copper recycled in China in 2019 has reached 45,980 tons, which is 7 times that of 1995. This is mainly due to the continuous enhancement of the awareness of used copper.
Recycling of used copper has brought great convenience to the development of Chinas economy. Taking the recycling of used wire and cable as an example, the recycling of abandoned and retired wire and cable can avoid the emergence of industrial waste and save resources. Secondly, the improvement of the circulation rate of used copper not only reduces the economic pressure on the traditional production industry, but also helps to optimize the environment by reducing the continuous discharge of industrial waste.
Apart from the application of waste copper wire, the use of waste copper in China is mainly based on the principle of resources and pollution abatement and the environmental protection concept of sustainable development. The main recycling methods for waste copper are physical and chemical methods, such as high temperature smelting, electrolytic recovery, metal extraction, etc., which can be used for the production of copper products and parts with certain functions.
In addition, China has also formulated a series of laws and regulations to standardize the recycling of used copper. For example, the Regulations on the Management of Hazardous Waste in China stipulates that if the recovery rate of dangerous waste is low, it should be disposed of by harmless treatment; the Production Safety Law of China stipulates that the recovery rate of used copper resources should meet the national requirements.
In short, the recycling of used copper resources has great potential for reducing environmental pollution, saving resources and increasing economic benefits through the utilization of used copper resources. China will pay more attention to the development of waste copper industry in the future, focus on the establishment of effective utilization and recovery system and improve the management, recovery and utilization level of used copper resources.
