Conserve fossil fuel feedstocks 2. Reduce energy consumption 3. Reduce amount of solid waste going to landfill 4. Reduce CO2, NO and SO2 emissions. 1 of 8 What is plastic process scrap recycling? Recycling polymers left over from the production of plastics. More like reprocessing. 2 of 8 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. 6 of 8 How is steel so easily recycled? Sorted by magnets and then cleaned by incineration. All steel can be recycled apart from aerosols. 7 of 8 How are carbon emissions reduced by recycling? Less energy required to produce a tonne of material from recycled material than from new raw materials. 8 of 8
