1. Aluminum
Aluminum scrap is the most essential input material to the recycling process.Aluminum recycling is the process by which scrapaluminum can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminum through the electrolysis of aluminum oxide.
2. Copper
Copper scrap is one of the most luxurious recycled materials besides gold. Scrap copper has numerous uses in homes since it can conduct electricity. It is often used as an electrical and heat conductor. Copper is a metal that is typically used almost everywhere because of its great advantages.
3. Lead
Lead is a highly corrosion resistant, dense, ductile, and malleable blue-grey metal, which has been used for at least 5000 years. Lead has the highest rate of recycling of all the metals. Due to its corrosion resistance, lead scrap is available for recycling, decades or even centuries after it is manufactured.
