Studies have shown that Polyethylene terephthalates may leach carcinogens.To recycle, the plastic is crushed and then shredded into small flakes which are then reprocessed to make new PET bottles, or spun into polyester fiber.This recycled fiber is used to make textiles such as fleece garments, carpets, stuffing for pillows and life jackets, and similar products.#2 - HDPE (High-Density Polyethylene) - Correct Answers✅HDPE plastic is the stiff plastic used to make milk jugs, detergent and oil bottles, toys, and some plastic bags.HDPE is the most commonly recycled plastic and is considered one of the safest forms of plastic. It is a relatively simple and cost- effective process to recycle HDPE plastic for secondary use.HDPE plastic is very hard-wearing and does not break down under exposure to sunlight or extremes of heating or freezing.For this reason, HDPE is used to make picnic tables, plastic lumber, waste bins, park benches, bed liners for trucks and other products which require durability and weather-resistance.#3 - PVC (Polyvinyl Chloride) - Correct Answers✅PVC is a soft, flexible plastic used to make clear plastic food wrapping, cooking oil bottles, teething rings, children's and pets' toys, and blister packaging for myriad consumer products.It is commonly used as the sheathing material for computer cables, and to make plastic pipes and parts for plumbing. 1 / 2
