PHAs (polyhydroxyalkanoates) are polyesters biosynthesized by a bacterium fed by inexpensive oils derived from the seeds of plants such as canola, soy, and palm.
In stark contrast to the toxic manufacturing methods used to make petro-plastics, our PHA bioplastics occur in the cells of the bacteria during growth.
PHA Achieves Global-Scale Capabilities.
Danimer Scientific uses canola oil as feedstock for PHA-producing bacteria. We begin the PHA production process by cultivating the bacteria in a canola-oil-based nutrient environment. The organisms manufacture PHA in their cells through biosynthesis.
Through proprietary manipulations of the nutrient environment and extremely controlled and optimized calculations, Danimer Scientific scientists produce PHA quantities ranging from half a liter to 10 liters in our R&D lab to multiple tanks with the capacity range of up to 20,000 liters.
In late March 2014, Tate & Lyle validated the replication of the proprietary process, bringing the promise of biosynthesis to fill global demand. Danimer Scientific is currently engineering and designing the world’s first PHA production facility.
Extraction Process Produces Toxin-Free Bioplastic.
To extract PHA from the cells of the cultivated microorganisms, Danimer Scientific uses a proprietary extraction process in which the biomass is removed to isolate the final purified PHA product.
The resulting PHA is then dried, producing the clean white powder ready to be pelletized. The absence of toxic chemicals is one of the qualities that makes Danimer Scientific PHA particularly appealing as a biopolymer for food-contact and medical purposes.
Reactive Extrusion Generates Customized PHA Feedstock.
Danimer Scientific biopolymer resins can be adapted to a wide range of products. Because of this, we can create customized mixtures of PHA polymers, tailored to the needs of plastic-product and packaging converters. Different physical properties required of the end product define the components, which are processed through reactive extrusion, a proprietary procedure that yields made-to-order resins.
Bioplastic customization makes our PHA polymer highly competitive due to the affordable price and targeted applications in the global marketplace.
