What key terms should I look for in alternative materials?
- Polylactic acid (PLA)- Polylactic acid (PLA) is a plastic polymer derived from non-petroleum sources including cornstarch, tapioca roots, and sugarcane. When marked for identification, it bears the number "7" in the center of the triangular recycling symbol. It is visually similar to PET products.
- Polyethylene terephthalate (PET)- Polyethylene terephthalate (PET) is a common plastic polymer type. When marked for identification, it bears the number "1" in the center of the triangular recycling symbol and may also bear the letters "PETE" or "PET". A PET container usually has a small dot left from the manufacturing process, not a seam. It does not turn white when bent. Food serviceware made from PET is usually transparent green or clear.
- Polypropylene #5 (and variants)- Polypropylene #5 is a plastic polymer that results in more rigid products than products made of PET and PLA. When marked for identification, polypropylene #5 items may bear the label “PP” or the number “5” in the triangular recycling symbol. Polypropylene #5 food serviceware products are most commonly clear or opaque black.
