It can also make the recycling process easier for some facilities. Rinsing recyclables isn’t required, but it does help to keep pests and odors away.Kitchen utensils (donate if in good shape).

Purification is done to guarantee the final product is of high quality and free of contaminants. Still, the energy required to melt and recycle metals is much less than the energy that is needed to produce metals using virgin raw materials. A considerable amount of energy is used in this step. Each metal is taken to a furnace that is specifically designed to melt that particular metal based on its specific properties. Melting of the scrap metal takes place in a large furnace.
The small pieces have large surface to volume ratio that can be melted using less energy as compared to when they are in large pieces of metal. The metals are broken down into tiny pieces or sheets to allow further processing. In automated recycling operations, magnets and sensors are used to aid in material separation.Īfter sorting, the next step is to compact the metal, so it can be handled on conveyor belts easier. Hammer mills then shred the metal into pieces.Īfter crushing the metal, the shredding process starts. Sorting involves separating metals from the mixed scrap metal stream or the mixed multi-material waste stream. Once the metals have been collected, the next important step is to sort the metals. It simply involves collecting all materials that are made of metals. This is the first and most important step in industrial metal recycling. A metal recycling center follows the following processing steps.
