The invention relates to processes for extracting polyhydroxyalkanoate
from a biomass, comprising admixing the biomass with an organic solvent
for from 1 second to 15 minutes at a first temperature of from 5.degree.
C. below the melting point of the polyhydroxyalkanoate to 10.degree. C.
above the melting point of the polyhydroxyalkanoate and at a pressure of
from 1 bar to 10 bar to provide a composition comprising the organic
solvent and polyhydroxyalkanoate.
