Revise: Recycling PolymersBecause crude oil is a finite, non-renewable resource, continually manufacturing new polymer increases demand for a limited starting material. Recycling existing polymer can reduce this demand.
Organise extended answers around the three required ideas: economic implications, availability of starting materials and environmental impact.
Explain rather than merely name each point: for example, recycling conserves crude oil because less new polymer needs to be manufactured from crude-oil-derived starting materials.
