Recycle Numbers on Plastic Water Bottles

I am often asked, what do those numbers inside the recycle symbol on the bottle of my plastic bottle mean? Below, I’ve listed what the numbers actually mean. Their names correspond with the numbers in the image above.

On a side note, not all containers are labeled and a recycling symbol on a product doesn’t mean it’s recyclable. Commonly, only #1 and #2 with narrow necks are recyclable, but some communities recycle other plastics with narrow necks. Check with your local municipality or waste disposal company.

PETE: Polyethylene terephthalate ethylene, used for soft drink, juice, water, detergent, cleaner, and peanut butter containers.

HDPE: High density polyethylene, used in opaque plastic milk and water jugs, bleach, detergent and shampoo bottles, and some plastic bags.

V or PVC: Polyvinyl chloride, used for cling wrap, some plastic squeeze bottles, cooking oil and peanut butter jars, detergent, and window cleaner bottles.

LDPE: Low density polyethylene, used in grocery store bags, most plastic wraps, and some bottles.

PP: Polypropylene, used in most Rubbermaid, deli soup, syrup and yogurt containers, straws and other clouded plastic containers, including baby bottles.

PS: Polystyrene, used in Styrofoam food trays, egg cartons, disposable cups and bowls, carryout containers, and opaque plastic cutlery.

Other: Usually polycarbonate, used in most plastic baby bottles, 5-gallon water bottles, “sport” water bottles, metal food can liners, clear plastic “sippy” cups and some clear plastic cutlery. New bio-based plastics may also be labeled #7.
