When plastic bottles are recycled, they undergo a multi-step process to transform them into new materials. First, the plastic is sorted, chopped, and ground into chips, which are then washed to remove labels, caps, and adhesives.1
The specific transformation depends on the type of plastic:
- PET (Polyethylene terephthalate): Often recovered from beverage bottles, PET can be washed, dried, and melt-spun into fibrous filling for pillows and clothing, or used to create carpets. When collected in a highly pure state, it can also be recycled back into its original uses or broken down into chemical precursors for resynthesis.12
- HDPE (High-density polyethylene): Frequently sourced from thin-walled containers like grocery bags, this plastic is often converted into more durable, thick-walled products such as flowerpots.1
- PVC (Polyvinyl chloride): Bottles made from PVC are commonly repurposed into items like traffic cones.1
Because recycled plastics often experience changes in molecular weight or quality during their initial use, they are frequently directed toward less-demanding applications than their original form.1
