Technical Abstract: Commercial development of poly-3-hydroxybutyrate (PHB) as a fully biodegradable thermoplastic replacement has been explored since the late 1970s. Production costs have never allowed PHB to become cost competitive with petrochemical polymers, partly due to high cost of polymer recovery and separation. We are developing applications for oligo- and low molecular weight PHB that carry lower recovery costs than high molecular weight polymer. We have explored the use of low molecular weight (Mw <10 kDa) polymer as a plasticizer and in non-woven sheets. In addition, we are investigating the production of excreted oligo-3HB from low cost carbon substrates in a microbial system.
