Polyester is a petroleum-based plastic made from polyethylene terephthalate, or PET—the same plastic as water and soda bottles. Recycled polyester can be made from old polyester clothes as well as other similar plastic products, and may be labeled as “eco-fleece.” Patagonia, a brand of outdoor wear, pioneered a program where customers can send back their worn-out polyester items to be recycled and sold again. In addition to sportswear, more upscale items such as suits are being made from this material. To protect nicer items from the agitation of a washing machine, have them dry cleaned with GreenEarth so they last longer without the use of toxic chemicals. While recycling is a hallmark of the environmental movement, the chemical process used to melt down and remake polyester is not always eco-friendly. Even so, purchasing recycled rather than new polyester items reduces the amount of oil needed to produce garments, and reduces the amount of polyester going into landfills.
