摘要： 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.

摘要： A biocomposite is produced from natural fiber fabrics embedded in a matrix of biosynthetic polyhydroxy-alkanoate (PHA) polymers. The PHA is synthesized using aerobic microbial biosynthesis using mixed bacterial cultures and a feedstock containing anaerobic degradation products such as methane and volatile fatty acids derived from microbial biodegradation of organic waste materials, which may include waste biocomposites. Monomers may be added to the synthesized PHA polymer to control mechanical properties of the resulting biocomposite. The natural fibers and/or PHA may be pretreated using various techniques to improve the bond between the fibers and the PHA resin matrix and water absorption resistance of the fibers. The composite may be a laminate of treated and untreated fabric layers, or differently treated layers, to achieve good in-service performance as well as rapid and/or optimal biogas production when taken out of service and put in an anaerobic environment to degrade.

摘要： A composite material includes a matrix composed of a polyhydroxyalkanoate (PHA) polymer and a filler composed of particles dispersed in the matrix. The particles are composed of naturally-derived materials (e.g., ground bone meal or pumice powder), have a microporous microstructure, have a low hygroscopic expansion, and are less than 1.0 mm in size. Preferably, the matrix and the filler together constitute 100% by weight of the composite material, and at most 30% by volume of the composite material is consumed by the filler. The composite material may take the form of an anaerobically biodegradable article of manufacture such as a building material a coating of a building material or other article.
