The patent application relates to a method of producing a monomer component from a genetically modified polyhydroxyalkanoate (PHA) biomass, wherein the biomass is heated in the presence of a catalyst to release a monomer component from the PHA.

Process for producing a monomer component from a genetically modified polyhydroxyalkanoate biomass

Polymer systems comprising poly(vinyl chloride), a non-petroleum based filler, and a polyester additive, wherein the polymer system is highly filled, and articles made therefrom, are described. The high loading of filler (e.g., talc, calcium carbonate or a combination thereof) is achieved by incorporation of polyester additives such as polyhydroxyalkanoates. High filler loading without significant reduction of relevant material properties can be associated with cost savings and environmental benefits.

Highly filled polymer systems

Compositions of biobased polymer blends of polymers and a polyhydroxyalkanoate copolymer are described. In certain embodiments, the copolymer is a multiphase copolymer blend having one phase a glass transition temperature of about &#x2212;5&#xb0; C. to about &#x2212;50&#xb0; C. Methods of making the compositions of the invention are also described. Also articles, films and laminates made from the compositions are described.

Solar biofactory, photobioreactors, passive thermal regulation systems and methods for producing products

The present invention provides fractional condensation apparatuses, systems and methods that can recover volatile products from highly diluted liquid and vapor feed mixtures with high purity and recovery yield, both in batch and continuous distillation, while being also designed to achieve low-cost and efficient recovery processes. Single apparatuses and columns can be connected to each other to expand or shrink the column length for desired separation. The apparatuses, systems and methods can be applied to separate mixtures with both narrow and wide boiling point ranges.

Fractional condensation processes, apparatuses and systems

A method of separating a polymer from a biomass containing the polymer, includes contacting the biomass with a solvent system, the solvent system including a solvent for the polymer and a precipitant for the polymer, to provide a residual biomass and a solution that includes the polymer, the solvent for the polymer and the precipitant for the polymer; and applying a centrifugal force to the solution and residual biomass to separate at least some of the solution from the residual biomass; where, the polymer is a polyhydroxyalkanoate; the precipitant comprises at least one alkane; the solvent for the polymer is selected from the group consisting of ketones, esters and alcohols and combinations thereof; and the biomass comprises a slurry of the biomass and water.

Polymer extraction methods

This invention relates to single solvent polymer extraction methods.

Single solvent polymer extraction methods

A method of isolating a PHA, includes combining the PHA, a first solvent and a second solvent to form a combination, the first solvent being capable of forming an azeotrope with the second solvent; and heating the combination to form the azeotrope of the first and second solvents.
