PLASTIC GUIDE

Plastics are widely used to store and package foods and beverages. Uses include disposable and reusable containers, plastic wraps, cutlery,
water bottles and baby bottles. Plastic is convenient, lightweight, unbreakable and relatively inexpensive. However, there are both environmental and health risks from the widespread use of plastics.
Environmental problems: Most plastics are made from petroleum, a non-renewable and mostly imported resource. Plastic packaging also creates unnecessary waste. Although plastic is lightweight, it is bulky, so it takes up a large volume of landfill space.
Health risks: Use of plastics in cooking and food storage can carry health risks, especially when hormone-disrupting chemicals from some plastics leach into foods and beverages.
Plastic manufacturing and incineration creates air and water pollution and exposes workers to toxic chemicals.
What plastic labels mean
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.
PVC or V: 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, carry-out 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.
