Plastics are complex to recycle because:
-
There are many different types of plastics, each with unique chemical properties.
-
Many plastics contain additives, colourants, or fillers that affect how they can be processed.
-
Mixing different plastic types can contaminate recycling streams, reducing the quality of recycled material.
-
Some plastics degrade in quality each time they are recycled, limiting the number of recycling cycles.
This complexity means recycling plastics requires careful sorting and processing to be effective.
