Have you ever see a recycle symbol with number in it at the bottom of a plastic bottle?
That is the SPI (Society of the Plastics Industry) resin identification coding system.
These markers DO NOT MEAN "the plastic can be recycled" OR "the container uses recycled plastic". These markers only identify the plastic type.
| Plastic recycling code number | Types of plastic | Common use for this type of plastic |
 |
Polyethylene terephthalate (PET) | Mineral water bottle, rigid box for fresh produce |
 |
High density polyethylene (HDPE) | Opaque bottles like for shampoo or detergent |
 |
Polyvinyl chloride (PVC) | Cling wrap, some plastic squeeze bottles, plumbing pipes |
 |
Low density polyethylene (LDPE) | Plastic grocery bags, most plastic wraps. |
 |
Polypropylene (PP) | Clouded bottles or containers like for ice-cream or yoghurt. |
 |
Polystyrene (PS) or expanded polystyrene (EPS) | Styrofoam cups, trays. Disposable plates, packaging "peanuts". |
 |
Other materials which cannot be classified in any of the above. (e.g polycarbonate, poly-amide and new biodegradable plastics) | Car parts, computer casings, rigid plastic trays used by bakers. |
Despite all that, Do you know that NOT ALL types can actually be recycled? Now you know what this markers mean, but do you know which one can be recycled and which are not! For your Further Reading Click Here!
