Recycling Symbols: A Review

This is a guest post by John Simonetta, owner of ProformaGreen, an eco-friendly promotional items consultancy. John’s blogs are designed to keep us up to date on the “greening” of his industry.

When Proforma Green goes to events we often get asked questions on what the different recycling symbols on plastic items stand for. I thought this might be a question some of our readers would like answered as well and so decided to re-post here information on the symbols first put together by thedailygreen.com.

PET or PETE (polyethylene terephthalate)

Found in: Soft drink, water and beer bottles; mouthwash bottles; peanut butter containers; salad dressing and vegetable oil containers; ovenable food trays.

Recycling: Picked up through most curbside recycling programs.

Recycled into: 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. It poses low risk of leaching breakdown products. Recycling rates remain relatively low (around 20%), though the material is in high demand by remanufacturers.

HDPE (high density polyethylene)

Found in: Milk jugs, juice bottles; bleach, detergent and household cleaner bottles; shampoo bottles; some trash and shopping bags; motor oil bottles; butter and yogurt tubs; cereal box liners.

Recycling: Picked up through most curbside recycling programs, although some allow only those containers with necks.

Recycled into: 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 carries low risk of leaching and is readily recyclable into many goods.

V (Vinyl) or PVC

Found in: Window cleaner and detergent bottles, shampoo bottles, cooking oil bottles, clear food packaging, wire jacketing, medical equipment, siding, windows, piping.

Recycling: Rarely recycled; accepted by some plastic lumber makers.

Recycled into: 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.

LDPE (low density polyethylene)

Found in: Squeezable bottles; bread, frozen food, dry cleaning and shopping bags; tote bags; clothing; furniture; carpet.

Recycling: LDPE is not often recycled through curbside programs, but some communities will accept it. Plastic shopping bags can be returned to many stores for recycling.

Recycled into: Trash can liners and cans, compost bins, shipping envelopes, paneling, lumber, landscaping ties, floor tile.

LDPE is a flexible plastic with many applications. Historically it has not been accepted through most American curbside recycling programs, but more and more communities are starting to accept it.

PP (polypropylene)

Found in: Some yogurt containers, syrup bottles, ketchup bottles, caps, straws, medicine bottles.

Recycling: Number 5 plastics can be recycled through some curbside programs.

Recycled into: 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 so is often chosen for containers that must accept hot liquid. It is gradually becoming more accepted by recyclers.

PS (polystyrene)

Found in: Disposable plates and cups, meat trays, egg cartons, carry-out containers, aspirin bottles, compact disc cases.

Recycling: Number 6 plastics can be recycled through some curbside programs.

Recycled into: Insulation, light switch plates, egg cartons, vents, rulers, foam packing, carry-out containers.

Polystyrene can be made into rigid or foam products — in the latter case it is popularly known as the trademark Styrofoam. Evidence suggests polystyrene can leach potential toxins into foods. The material was long on environmentalists’ hit lists for dispersing widely across the landscape, and for being notoriously difficult to recycle. Most places still don’t accept it, though it is gradually gaining traction.

Miscellaneous

Found in: Three- and five-gallon water bottles, ‘bullet-proof’ materials, sunglasses, DVDs, iPod and computer cases, signs and displays, certain food containers, nylon.

Recycling: Number 7 plastics have traditionally not been recycled, though some curbside programs now take them.

Recycled into: Plastic lumber, custom-made products.

A wide variety of plastic resins that don’t fit into the previous categories are lumped into number 7. A few are even made from plants (polyactide) and are compostable. Polycarbonate is number 7, and is the hard plastic that has parents worried these days, after studies have shown it can leach potential hormone disruptors.
