* 100% recycled metals

    Copper is 100% recyclable without degradation, making it a permanent material with long service life and reducing the cost of product life cycle.

    According to the International Copper Association, the global copper recovery rate is about 60%, and about 30% of the copper supply comes from recycled copper.

    Compared with other metals, one of the bright spots of * * is that it is a small number of metals that can be recycled 100%; moreover, there is no loss and impact on the quality and performance of copper after reprocessing; moreover, in the process of copper recovery and processing, its energy efficiency is also very high, which is 80% ~ 90% lower than the original mining and processing energy consumption.

    The cumulative consumption of copper per capita in China is astonishing

    It is estimated that two thirds of the 550 million tons of copper produced after 1900 are still in use.

    These large quantities of copper bearing products exist in various forms in end use, equivalent to 20 years of copper production.

    The current energy transformation, that is, the transition from the traditional fossil fuel dominated energy structure to the new renewable energy, and the improvement of energy efficiency will greatly affect the demand and consumption of copper.

    According to relevant estimates, by 2050, China's per capita cumulative copper consumption will reach a historical peak, and the copper produced by recycling will meet all the demand.

    Copper and circular economy are inseparable

    Copper industry is a very concerned about resource recycling and sustainable development.

    For a long time, copper industry enterprises have been actively investing in advanced technologies and technologies to recover a large amount of waste heat, waste water and waste produced in the 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. Copper is an important material for many low-carbon technologies because of its strong functionality and excellent electrical and thermal conductivity. It is also an essential part of the global major energy infrastructure in the future.

    The energy consumption of copper reprocessing is lower than that of other materials, and only 13% of the energy consumption of primary processing is needed for reprocessing waste. At the same time, there are many by-products that can be used. The copper ore processing process can produce 19 kinds of available by-products, such as sulfuric acid, and slag can also be used in the construction industry.

    It is understood that due to the strong functionality of copper, the amount of material can be reduced. For example, with the same current carrying capacity, the diameter of copper cable is smaller than that of aluminum cable; waste copper can be directly used to make copper wire and cable, copper plate, copper bar, hardware products, water nozzle, etc.

    In terms of resource efficiency, there is only about 3% material loss in the smelting and production process, forming symbiotic formats with many industries, such as zinc and other metals.

    At present, metal recycling is facing challenges

    In the first half of 2017, the domestic output of recycled copper reached 1.35 million tons, an increase of 8% over the same period of the same period last year, and the domestic waste copper recovery was close to that of mineral copper.

    During the 13th Five Year Plan period, China's copper used in electrical and electronic products, automobiles, construction and other fields will enter the peak period of scrap. It is estimated that the domestic copper waste will generate about 2.8 million tons in 2020.

    At present, the recovery of all solid wastes of metals is facing challenges. How to meet the needs of human beings for a better ecological environment and promote the green development of economy requires the wisdom and efforts of all people.
