Recycling of metals helps protect the environment as well as save energy. It saves on the water and energy used in the production of new metals and cuts the amount of waste that goes into landfills.
Metal recycling helps to save the fast depleting natural resources such as the iron ore, water and fossil fuels that furnish the energy required for production..
Recycling metals reduces the amount of CO2 released into the air as it requires a fraction of the energy needed for producing virgin metal.
Thus it helps reduce air, water, and land pollution to a very large extent.
With the recycling of metals, there is lesser wastage/usage of water by the metal extraction industry.
The metal recycling industry recycles millions of tons of metal each year and provides job opportunities to hundreds of people, thus contributing to the economic growth of many nations.
Steel is recycled from scrap metal using techniques such as electric arc furnace and blast furnace process.
Aluminum scraps like cans, foils etc. can be collected and recycled using different processes. Aluminum is among the most recycle friendly metals available and it consumes less amount of energy to recycle. In countries like Brazil, the scraps are collected by various organizations of scavengers and exchanged for utility goods such as school kits, food baskets, and furniture.
Lead is easy to recycle and reuse repeatedly as it does not lose its properties and the recycled product, also called Secondary lead is of the same quality as the metal extracted directly from the ores.
Copper wires from electrical equipment and printed circuit boards of electronic equipment are a source of copper and precious metals like silver or gold respectively.
