PHA’s are polyhydroxy-alkanoates: bio based and biodegradable thermo-plastic polyesters. PHA’s have been developed for several years, mostly based on sugars or fats with pure culture fermentation.

PHARIO PHA is a different approach with many advantages:

  • less complex processing (mixed microbial cultures)
  • lower production costs (less feedstock, no commodity price volatility)
  • good quality PHA/PHBV’s (more on the product page)
  • positive environmental impact

The PHARIO concept creates a high and controllable quality PHA with fewer process elements and significant lower manufacturing costs.The source is municipal waste water and organic residuals from households or food industry: an abundant flow of valuable biomass, available globally.

How does it work? Its all about synergy

PHARIO approaches a full-scale municipal wastewater treatment plants as process units that produce functional biomass (activated sludge) with PHA storing capacities. Already most sewage treatment plants have this capability and others can be tuned to do this with minor modifications. Harvesting of this active biomass prevents the need to use feedstock and energy to grow the bacteria necessary for PHA production. Also municipal waste streams can be fed to these bacteria to produce the PHA. The full techno-economical report of the pilot phase, including datasheets, is available via the following link

Interested in partnerships

The process is scalable, controllable and applicable on most conventional wastewater treatment plants. Based on the current knowledge we estimate that in total 500.000 MT of PHA could be produced by the wastewater treatment plants of the large cities in Europe. We welcome application partners and strategic investors to join the journey during the demonstration and further commercialization of this concept.
