PHA

PHAs are microbiologically accumulated polyesters and are environmentally friendly substitutes to fossil based polymers. They have similar material properties as polypropylene (PP), one of the most widely used polymers in the plastics industry. Moreover, they are biocompatible and water resistant with broad applications in polymer industry and medicine. Further, they are carbon neutral, biodegradable and do not release any toxins while being degraded. For these reasons, PHAs are considered the most promising bioplastic. However, the current production of PHAs is small, as PHAs are up to 4 times more expensive to produce than their fossil-based equivalents using existing methods. Of the total production cost, more than one-fourth relates to the extraction of PHAs from the producing bacteria cells.

 

Bioextrax has a patented (Swedish and EU patent granted, US patent pending) solution to carry out the extraction. The unique feature of Bioextrax’ technology is that:

 

  1. It is completely biobased, free of chemicals and solves
  2. It produces intact PHA granules, and
  3. It leaves a nutrient-rich solubilized non-PHA bacterial biomass as a co-product (20-50 wt% of cell biomass).

This means that we can reduce the production cost significantly, while producing a higher quality product in a more environmentally friendly way.
