Kaneka Biopolymers is a division of Kaneka Corporation and was created out of the need to provide an alternative solution to single-use plastics. The Kaneka Biopolymers brand is Kaneka PHBH™. It’s a plant-based biopolymer.
Kaneka PHBH are biopolymers in the family of PHAs or Polyhydroxyalkanoates.
Kaneka PHBH grades are polyesters produced by microorganisms. Kaneka PHBH grades are produced via the fermentation of plants. Kaneka’s PHBH is made from plant oil and fat, and other ingredients. Kaneka uses Cupriavidus necator bacteria to produce their PHBH.
Kaneka PHBH combines 2 monomers together: 3-Hydroxyhexanoate with 3-Hydroxybutyrate to make different types of PHBH.
The concentration of each monomer during the polymerization process will create a different type of copolymer that can lead to different types of applications. This technique allows the creation of multiple PHBH grades that will mimic a wide variety of plastic shapes.
Kaneka PHBH is marine biodegradable, soil biodegradable and compostable.
Kaneka PHBH has superior advantages compared with other biopolymers.
Kaneka PHBH production
Kaneka started producing PHBH at their Takasago headquarters in Japan in 2011. The production capacity was 1.000 metric tonnes per year.
They scaled up their Takasago plant to an annual capacity of 5.000 tonnes / year in December 2019 and they’re considering increasing PHBH production to 20.000 tons in the future.

Kaneka PHBH Applications
PHBH bioplastics is exported to Europe to make bags. PHBH is also used to make agricultural mulch films, straws, cutlery, food containers and packaging materials.
Kaneka and Shiseido are working together to develop cosmetic containers.
In the future, Kaneka may want to explore the production of bottles and containers, auto interiors and electrical equipment.
