Answer 1

(7) Polymer that is most recyclable us the polyethylene tetephthalate = PET. I could be crushed to make new things like PET bottles or could be processed in polyester fibre Highert recycling value is of aluminium which is recycled propekly with loss of its quality and fuus seen to be in high demand. Polypropylene requires the mot energy to make with a high breakdown stength of 43o mumy o one reason the two polyproplylene staples have different properties in the chart is the two samples have different molecular neights
