Japan's Toyota and a group of industry companies have developed the world's first system for recovering copper materials from waste car wiring harnesses, which means that another source of raw materials may be formed.Copper recycling technology has long been used in the recycling of AAC cables.
These cooperative enterprises include 8 automobile dismantling plants with business cooperation such as Yazaki and Toyota Tsusho.
Copper is one of the most sought-after metals in the world, but studies have shown that according to current consumption levels, the world's mineable copper materials will be exhausted by the middle of this century. In recent years, the demand for copper for infrastructure construction in emerging markets has increased substantially. At the same time, the production of electric motors in hybrid systems also requires copper.
In the past, it has not been possible to use mechanical methods to recycle copper from scrap car wiring harnesses, but only a year later, Toyota came up with a new method, which is to extract the metal from pollutants by separating trace amounts of magazines during the dismantling process. Moreover, Toyota said that the purity of the extracted copper reaches 99.96%, which can almost match the new copper level.
Subsequently, in 2013, Toyota put this technology into its Honsha plant for testing. After strict quality control, the recovered copper finally successfully entered the automobile production process.
Toyota said that through this technology, it is expected to produce about 1,000 tons of copper per year.
