Kaneka Biopolymers PHBH, trademarked Green Planet, is a member of the PHA family of biopolymers. PHBH is 100% non-toxic, plant-based and fully compostable. PHBH is made by fermenting selected beneficial soil bacteria in a warm bath with seed oil feedstock. The bacterium convert the seed oils into the building blocks of the bioplastic known as PHBH. Using a solvent-free technique, Kaneka filters the ferment and pelletizes remaining resin for injection and blow molding applications.
PHBH was discovered in the 1930’s by a Japanese soil biologist. 90 years later, Kaneka has fully commercialized this process and is breaking ground on a second and larger PHBH manufacturing plant.
PHBH is globally certified 100% biobased and soil degradable, leaving behind no microplastics in the environment.
More remarkable, TUV has granted marine degradable certification to PHBH straws and thin films.
