One of the biggest highlights of copper metal and other metals is that it is a few metals that can be recycled 100% repeatedly. Moreover, there is no loss and effect on the quality and performance performance of the copper after reprocessing. In the process of copper recovery, the energy efficiency is very high, which is 80%~90% lower than the energy consumption of the original mining.
It is estimated that 2/3 of the 5.5 billion tons of copper produced after 1900 are still in use. These large amounts of copper - containing products exist in a variety of forms in terminal use, equivalent to 20 years of copper production. The current energy transformation, namely the transition from traditional fossil fuel dominated energy structure to new renewable energy transformation, and the improvement of energy efficiency will largely affect copper demand and consumption.
According to the relevant estimates, by 2050, China's per capita copper consumption will reach a historical peak, and the copper produced by recycling will meet all demand. The copper industry is an industry that pays great attention to the recycling and sustainable development of resources. Copper industry has been investing in advanced technology and technology to recycle waste heat, waste water and waste from mining and smelting process. The recovery of these resources not only contributes to the green development of the industry, but also brings economic value.
The relationship between copper and circular economy is also inseparable. Functional and excellent conductivity and thermal conductivity are important materials for many low carbon technologies. They are also necessary parts of the world's major energy infrastructure. Copper reproduction is less energy consuming, and waste reprocessing only needs 13% energy consumption for the first processing, which is lower than other materials. At the same time, more byproducts can be used, and 19 kinds of available by-products, such as sulphuric acid, can be produced in the process of copper ore processing, and the slag can also be used in the construction industry.
It is understood that because of the strong functional characteristics of copper, the amount of material can be reduced. For example, the same load flow, copper cable diameter is more thin than the aluminum cable. Copper can be directly used, made of copper wire and cable, copper, copper, metal products, faucets etc.. In the process of resource efficiency, only about 3% of the material loss in the process of smelting and production has formed a symbiotic form with many industries, such as zinc and other metals.
Zhou Sheng, President of China International Copper Association, said at the forum that the current metal and even solid waste recycling is facing challenges. How to meet the needs of mankind for the beautiful ecological environment and promote the green development of the economy needs everyone's intelligence and efforts. "I look forward to being able to communicate with you more in this field, to jointly promote the formulation and implementation of favorable policies, explore scientific measurement and evaluation methods, promote more advanced and innovative technologies, and provide suggestions for green development of industries and countries."
The first half of 2017, domestic renewable copper production reached 1 million 350 thousand tons, an increase of 8%, domestic waste recycling has close to copper mineral. "13th Five-Year" period, China's electrical and electronic products, automotive, construction and other areas with copper will enter the peak of scrap, is expected in 2020, the domestic copper scrap generated about 2 million 800 thousand tons.
It is reported that the International Copper Association also participated in the 2017 China Circular Economy exhibition, showing the application of copper in green and innovation, including electric vehicles, copper cage culture, solar energy, wind power, air source heat pump and so on.
The International Copper Association, founded in New York in 1989, is a non-profit international organization dedicated to the research and promotion of the social value and effective use of copper. The International Copper Association, which entered China in 1995, was the first international organization to assist the Chinese government in the planning and implementation of sustainable economic development. At present, the International Copper Association has more than 40 members, including most of the world's copper mining enterprises, smelters, and the world's leading copper and copper alloy processing enterprises.
