1. A process for the preparation of a composite material made of a fibrous material and binders in the form of a polymer of hydroxyfatty acids the monomers of which are derived from saturated or unsaturated 3-hydroxyfatty acids having from 4 to 16 carbon atoms in the fatty acid residue, characterized in that microorganisms producing said polymer of hydroxyfatty acids are grown in the presence of fibrous material, wherein said fibrous material serves as a nutrient for the microorganisms, and another carbon source, the microorganisms are harvested along with the fibers, and pressed in a dried or moist condition, optionally using additional fibrous materials, into composite materials.
