Overview of the Whole Copper Recycling Chain
Copper is of good characteristics. It is easily stretched, molded, and shaped; is resistant to corrosion;
conducts heat and electricity easily. Therefore, copper is widely used in construction, power generation
and transmission, electronic products manufacturing, and the production of industrial machinery and
transportation vehicles. At the same time, as a non-renewable resource, copper is also one of the most
widely recycled of all metals; approximately one third of the consumed copper worldwide is recycled.
Copper recycling is very vital for today’s industry and environment. The use of scrap copper is a
necessary means to compensate for declining supplies of mined copper. Besides, copper recycling has
been a global business, which contributes to keeping local resources balance, creating job opportunities,
saving landfill site space and stimulating the recycling of other metals. By recycling copper, our earth and
water is also free from being polluted by it. Compared with extracting copper from copper ore, copper
recycling only needs 10% of its energy consumption. This energy saving leads to the conservation of
valuable reserves of oil, gas or coal and reduces the amount of CO2 released into the atmosphere.
As we have mentioned, copper recycling is an important part of the whole supply chain.Then where does
the copper scrap come from? There are two kinds of copper scrap: old scrap an new scrap. Old scrap
comes from the public. It is collected from discarded, dismantled or obsolete products at the end of their
lives. For example, copper wire scrap of each home appliance, ac radiator scrap, old taps from bathroom.
New scrap comes from factories which make articles from copper, brass or bronze. Their machines will
produce offcuts and shavings that can be collected and returned for recycling.
