Plastic no. 3 pipes

Plastic labeled with an SPI code of 3 is made with Polyvinyl Chloride, or PVC. PVC is not often recycled and it can be harmful if ingested. PVC is used for all kinds of pipes and tiles, but it's most commonly found in plumbing pipes. This kind of plastic should not come in contact with food items. Recycled PVC is used to make flooring, mobile home skirting, and more.
