Explanation:

Recycling

It is the process in which materials are extracted to reuse or recover them for other purposes.

Among all the recycling materials, plastic is the most difficult material to recycle because polymer is made up of different types of polymer raisins. So, it's impossible to recycle different types of plastics together as they all melt at different temperatures. Before recycling, first plastics need to be separated which is time consuming and costly also. Also, only certain types of plastics can be recycled. Most of the plastics get worse when recycled. So, these type of plastics are mixed with virgin plastics and other materials to become valuable.
