Recycling
•Thermoplastics can be remelted and reused, and thermoset plastics can be ground up and used as filler, although the purity of the material tends to degrade with each reuse cycle.
•There are methods by which plastics can be broken back down to a feedstock state.
•Typically, workers sort the plastic by looking at the resin identification code, although common containers like soda bottles can be sorted from memory.
