July 12, 2009 at 7:45 pm Leave a comment

Plastics and products with the number 3 recycling symbol on there are often made into pipes, fencing, and non-food bottles, although they do not have to be those materials.   The #3 recycling symbol is referred to as Polyvinol Chloride, better known as PVC.  As you probably know, PVC is used A LOT – pools and plumbing are two gigantic categories utilizing PVC.

Some quick facts about #3 recycling symbol plastics:

  1. #3 recycling symbol plastics are the third most widely used thermoplastic polymer after polyethylene (#1 recycling symbol) and polypropylene (#5 recycling symbol).
  2. Over 50% of PVC manufactured is used in construction.
  3. #3 recycling symbol plastics can be made softer and more flexible by the addition of plasticizers.  In this form, PVC can be used in clothing and upholstery, and to make flexible hoses and tubing, flooring, to roofing membranes, and electrical cable insulation.
  4. The Unicode character for this symbol is U+2675
  5. Post-consumer PVC is not typically recycled due to the prohibitive cost of regrinding and recompounding the resin compared to the cost of virgin (unrecycled) resin.
  6. A new process of PVC recycling is being developed in Europe called Texiloop.[43] This process is based on a technology already applied industrially in Europe and Japan, called Vinyloop, which consists of recovering PVC plastic from composite materials through dissolution and precipitation. It strives to be a closed loop system, recycling its key solvent and hopefully making PVC a future technical nutrient.
