The mentality about the environment is changing. Every day there are more companies that make environmental management a basic component of their productive management. Today we will talk about why copper Scrap Wire Singapore is a good material for recycling
One of the most common actions that incorporate its management is recycling, a process that is combined with caring for the environment and reducing costs.
The mineral deposits can be exhausted, the raw material is not infinite, but thanks to recycling most metals are recycled in a high percentage.
We will hardly be left without copper, According to the Copper Development Association, the world’s known resources of the metal are estimated at 5.8 trillion pounds (15.26 x 10 kg approx.), Of which only 12% have been exploited as long story. Of this percentage, it is estimated that 80% still circulates around the world.
The more developed an economy is, the more copper it consumes. Therefore, since copper scrap wire singapore is of high durability, the need for more metal grows faster than the supply of waste.
On the other hand, today, most copper is used in the form of electric wires and cables, which require pure refined copper.
Domestic wires must have 99.9% one of the best metals for recycling purity, because the smallest contamination reduces their conductivity. Only 0.05% phosphorus or 0.08% iron reduce the transmission of electricity by one third.
Copper is 100% recyclable, does not lose any of its chemical or physical properties in the recycling process, can easily be incorporated into other production cycles and has few restrictions on its use.
Where is copper taken out for recycling?
The copper scrap wire singapore radiators of heat exchangers, thin wires, pipes, roofing sheets, electric cables…
What is recycled copper used for?
Copper for recycling is called copper scrap. It is classified and works in recycling plants as in the case of RECEMSA and by tons it is delivered to the foundries to use it as a raw material in their process
For the manufacture of pipes, roofing sheets, electronic chips, parts for motors and transformers, coins, … In short, for almost everything, you can see this many more detailed on our website in products: copper
Copper scrap wire singapore and its derivatives, either in its pure state or contained in a final product, can be recycled at all stages of the product’s life cycle.
The most significant rates of recycled copper use seem to be in Europe, with 45% (according to data from the International Copper Study Group).
On the other hand, the United States presents 33.3% (according to United States Geological Survey data).
How is copper recycled?
The processes to recycle copper vary according to the composition of the waste.
The pure copper waste can be melted directly. Its purity is checked by chemical analysis when it is still in a liquid state. Then it deoxidizes and leads to intermediate forms -such as ingots- to be used in other processes.
The residues containing oxides melt to form anodes that are then electro refined to obtain the desired level of purity.
In some alloys, such as brass and bronze, the copper residue melts and forms more alloys. In this case, it does not refine it again.
If the copper residue is mixed with other minerals, the cost-benefit ratio of the refining process is evaluated. In this way, if this ratio is very high -as in the case of the can and nickel that can only be separated by electro refining, the copper waste is destined for non-electrical purposes, that is, they do not require high levels of purity.
The economy of recycling
When promoting recycling, the reduction of productive costs is a key criterion. High quality waste costs 10% less than new refined copper cathodes
Copper and its alloys can be recycled relatively cheaply, with low energy consumption and minimal losses. Thus, if the alloys are made with recycled copper, the cost of the material can be significantly reduced.
But also, another basic criterion is the environmental one. Recycling not only helps to conserve raw material and reduce waste, but saves up to 75% of the energy used in primary copper production.
The copper residue, the metal that has already been used once, has the advantage of being present in metallic form in the medium. This avoids the energy waste of the process of extracting, transporting, melting and refining the material, since the energy needed to remelter and re-refines the waste is less.
