Recycling:
PET can be identified easily by locating its recycling code symbol. PET is denoted by the familiar triangular shaped arrows with the number 1 in the center. PET can be recycled into many other products besides bottles and jars. Other recycled PET products include ski coat fibers, fleece vests, and sleeping bag lining.
