The numbers found on plastic containers inside the recycling symbol are a
coding system for plastic containers to assist recyclers in sorting
plastic containers. The symbol is designed to be imprinted on the bottom of the plastic
containers. The numerical code appears inside the recycling symbol, a
three-sided triangular arrow. Here is a guide to what the numbers mean as well as examples of each number:

Below is a in-depth look at the numbers and the end result of what they are recycled into
1 - Polar fleece, fiber, tote bags, furniture, carpet, paneling, straps, (occasionally) new containers. PET
plastic is the most common for single-use bottled beverages, because it
is inexpensive, lightweight and easy to recycle.
2 - Laundry detergent bottles, oil bottles, pens,
recycling containers, floor tile, drainage pipe, lumber, benches,
doghouses, picnic tables, fencing. HDPE is a versatile plastic with
many uses, especially for packaging. It is recyclable into many goods.
3 - Decks, paneling, mudflaps, roadway gutters, flooring, cables, speed bumps, mats.
PVC
is tough and weathers well, so it is commonly used for piping, siding
and similar applications. PVC contains chlorine, so its manufacture can
release highly dangerous dioxins. If you must cook with PVC, don't let
the plastic touch food. Also never burn PVC, because it releases toxins.
4 - Trash can liners and cans, compost bins, shipping envelopes, paneling, lumber, landscaping ties, floor tile. LDPE
is a flexible plastic with many applications.
5 - Signal lights, battery cables, brooms, brushes,
auto battery cases, ice scrapers, landscape borders, bicycle racks,
rakes, bins, pallets, trays. Polypropylene has a high melting
point, and is often chosen for containers that must accept hot
liquid.
6 - Insulation, light switch plates, egg cartons, vents, rulers, foam packing, carry-out containers. Polystyrene
can be made into rigid or foam products. It is
popularly known as the trademark Styrofoam.
7 - Plastic lumber, custom-made products. A
wide variety of plastic resins that don't fit into the previous
categories are lumped into number 7.
As a packaging distributor, it is easy for us to want to sell plastic
products - these items are an important part of our revenue. The fact that this versatile material is not only in our packaging products but also in in our cars, toys, clothing and home goods makes it that much more important in understanding the significance of plastic recycling codes.
We will continue to do our part in the education of recycling the products we supply. Please do your part in making sure plastic products are disposed of properly.
