(3) Used metals

Metals from composite wastes can be recycled to create new metal goods like cans, appliances, and automobiles. Recycling composite materials, such as those made of a combination of plastic and metal, has historically been difficult.

However, modern technological developments have made it possible to recover precious metals from composite waste, including e-waste and auto shredder residue (ASR).

Mechanical separation is one method for removing metals from composite waste. Using techniques like shredding, grinding, and air classification, the various materials present in the waste must be physically separated during this process.

Metals can then be separated from other materials by sorting the resulting material according to density and magnetic properties. Pyrometallurgical treatment is another technique for extracting metals from composite waste.

In order to extract the metal, this process involves heating the waste to high temperatures in the presence of a reducing agent, such as carbon. This technique allows for the separation of metals like copper and gold from the plastics and other materials present in the waste, making it particularly helpful for recovering metals from e-waste.

In addition to lowering the amount of waste dumped in landfills, recovering metals from composite waste also helps preserve natural resources. Numerous uses for the metals recovered from composite trash exist, including the development of new electronics and cars.

Finally, it has been difficult to recycle composite materials in the waste management industry, but new technological developments have made it feasible to extract precious metals from composite trash.
