There are seven types of plastic that can be recycled, each of which is identifiable by the triangle symbol on the container that identifies what resin it’s made of. The types of plastic that can be recycled are: PETE or PET (polyethylene terephthalate), HDPE (high-density polyethylene), V or PVC (vinyl), LDPE (low-density polythylene), PP (polypropylene), PS (polystyrene), and a category of miscellaneous products like nylon and 5-gallon water jugs.
