Method of producing polyhydroxyalkanoate compounded plastics having improved mechanical properties

摘要

A method of enhancing mechanical properties of compounds formed with polyhydroxyalkanoates (PHA) recovered by biomass where the biomass comprises PHA and non-PHA materials. The method includes dissolving the PHA and non-PHA materials in a solution and separating the PHA and non-PHA materials from the solution. Further, the method includes compounding the separated PHA material and at least some of the separated non-PHA material into a compounded plastic having improved mechanical properties.

1. A method of enhancing mechanical properties of compounds formed with polyhydroxyalkanoate (PHA) recovered from biomass, comprising:
a. providing a biomass comprising PHA and non-PHA materials, wherein the non-PHA materials include lipids or fatty acids; b. placing the biomass in at least one solution; c. dissolving the PHA and non-PHA materials in the at least one solution, wherein at least part of the biomass is not dissolved; d. separating the dissolved PHA and the dissolved non-PHA materials from the non-dissolved biomass; e. separating the dissolved PHA from the dissolved non-PHA materials; and f. compounding the separated PHA and at least some of the separated non-PHA materials into a compounded plastic including the PHA and having at least one improved mechanical property relative to a compound formed without including the non-PHA materials.
