Kaneka produces a unique biopolymer called 'Kaneka Biodegradable Polymer PHBH™' which is a 100% bio-based polymer produced by microbial fermentation from plant oils. The products are biodegradable to carbon dioxide and water under aerobic, anaerobic, soil and marine conditions. PHBH™ can improve biodegradability of other bio-polymers such as PLA, PBAT, PBS through blending.

Kaneka Biodegradable Polymer PHBH™ is bio-based and biodegradable yet strongly resistant to heat and hydrolysis and can act as a barrier to water vapour. It is the first ever 100% plant-based biopolymer to offer both flexibility and heat resistance. It exhibits a range of priorities from hardness through to softness as well as a number of key characteristics of polyethylene and polypropylene materials. In addition printability and dye-ability are very good.
