Plastic is everywhere. It’s hard to know what you can reuse, what you can recycle and what you can do to reduce your plastic consumption.

What do the numbers mean?

Look on the bottom of a plastic laundry detergent bottle or yogurt container. See the recycling triangle symbol with a number in the middle? Many people assume that indicates how to recycle the plastic. It’s actually the plastic resin content.

There are seven standard classifications for plastics. Check your municipality or city waste services website to see which plastics you can recycle where you live.

PET (polyethylene terephthalate)

Found in most water and beverage bottles and some packaging. Hard to de-contaminate. Proper cleaning releases harmful chemicals, like DEHA.

DO NOT REUSE

HDPE (high-density polyethylene)

Found in milk, detergent and oil bottles, toys and plastic bags. Considered one of the safest forms of plastic.

REUSABLE

PVC (vinyl/polyvinyl chloride)

Found in food wraps, food oil bottles, teething rings, pet toys and blister packaging. Produces toxins from manufacture through disposal. Avoid using for microwaving (use glass or microwave-safe crockery instead); wraps made from LDPE (#4) are safer.

DO NOT REUSE

LDPE (low-density polyethylene)

Found in shrink wraps, garment bags (from dry cleaners), squeezable bottles, furniture and plastic bags. Less toxic than other plastics.

REUSABLE

PP (polypropylene) 

Found in bottle tops, disposable diapers, medicine and syrup bottles, drinking straws, carpeting, bags and food wraps, yogurt and margarine containers. Considered one of the safest plastics.

REUSABLE

PS (polystyrene)

Found in plastic cutlery, foam packaging, egg cartons, take-out containers. May leach into food products.

AVOID

Other (LEXAN, polycarbonate, BPA a.k.a. bisphenol A)

Usually layered or mixed plastics.

DO NOT REUSE/AVOID

NOTE: Some plastics labeled “do not reuse” are still recyclable. Always check your municipal recycling guidelines before disposing or recycling plastic.
