Abstract:
Methods for producing bioplastics from biogas include techniques for the production of PHB using a dirty biogas (e.g., methane from landfill, digester) as both a power source for the process and as feedstock. Biogas is split into two streams, one for energy to drive the process, another as feedstock. Advantageously, the techniques may be implemented off the power grid with no dependence upon agricultural products for feedstock.
