    Furthermore, active research is being carried out for the biotransformation "upcycling" of plastic waste (e.g., polyethylene terephthalate and polyurethane) into PHA using Pseudomonas putida bacteria. [17] A PHA copolymer called PHBV (poly(3-hydroxybutyrate-co-3-hydroxyvalerate)) is less stiff and tougher, and it may be used as packaging material.

    where n is the number of monomers in the polymer chain, though a trace amount of the PET breaks down instead to bis(2-hydroxyethyl) terephthalate (BHET). [1] PETases can also break down PEF-plastic (polyethylene-2,5-furandicarboxylate), which is a bioderived PET replacement, into the analogous MHEF.
