As part of a NEDO project, an industry-university consortium led by Hitachi Zosen Corporation successfully developed a high-performance biocomposite material by finely and uniformly mixing bio trans-polyisoprene, which is produced from the non-edible biomass of Eucommia, with a versatile biopolymer (polylactic acid).

By dynamically crosslinking and combining with 10-30% bio trans-polyisoprene, the newly developed biocomposite material has an impact resistance value approximately 16-25 times greater than commercially available polylactic acid, which has had the brittleness problem, achieving impact resistance performance equivalent to petrochemicals (Figure 1). The elongation, one of the tensile properties, has also been drastically improved by approximately 9-30 times. It is expected that this biomass-derived composite material will be used as resins for 3D printers whose market is predicted to expand globally; as the interiors of automobiles and transportation equipment that require molding processes; and in the biomaterials field.
