PET (or PETE)
Polyethylene terephthalate: Used in clear plastic bottles Widely accepted for recycling.
Note that single-use bottles are not designed for storing water and bacteria may build up in screw threads. Reusable bottles should not be used to store hot liquids since this may degrade the plastic overtime.
High-density polyethylene: Used in milk and juice bottles, retail bags, and yogurt containers. HDPE is widely accepted for recycling.
V or PVC
Polyvinyl chloride: Used in food containers and utensils, pipe, children’s toys, clothing and accessories, binders/notebooks, and upholstery. Limited recyclability, primarily PVC pipe.
Low-density polyethylene: Used in thin plastic bags, grocery bags, bread bags, and squeeze bottles. Widely accepted for recycling; check with your sanitation department to see if they are accepted.
Polypropylene: Used in yogurt containers, margarine clubs, prescription bottles and straws. Recyclable; check with your sanitation department to see if accepted.
Polystyrene: Used in foam plastic cups and containers. Recyclable; check with your sanitation department to see if accepted.
Other: Used in food containers, water bottles, baby bottles, and plastic bags.
This category encompasses several types of plastic including polycarbonate (sometimes listed as PC), which can leach hormone-disrupting bisphenol-A into liquids. However, #7 plastics also include bio-based plastics such as those made from polylactic acid (PLA) derived from corn.
Not recyclable; however, some bio-based plastics such as PLA can be composted in municipal composters.
