What is plastic process scrap recycling?
Recycling polymers left over from the production of plastics. More like reprocessing.

What is post-use plastic?
Plastic material from products that have undergone a full service life.
3 of 8
Give some of the issues associated with post-use plastic recycling?
Collection & sorting - manual labour = expensive
4 of 8
What is meant by feedstock recycling?
Break down polymers into their constituent monomers which can be used in refineries or (petro)chemical production.
5 of 8
Give an example of a bioplastic?
Polymers made from plant sugars grown inside GM plants or microorganisms.

How is steel so easily recycled?
Sorted by magnets and then cleaned by incineration. All steel can be recycled apart from aerosols.

How are carbon emissions reduced by recycling?
Less energy required to produce a tonne of material from recycled material than from new raw materials.
