Polyhydroxyalkanoates (PHAs) are biopolymers that can be synthesised and internally accumulated by several microorganisms. They are incorporated into plastic formulations with reduced carbon footprint and improved biodegradability. The INCOVER collaborative project aims to optimise existing algae production infrastructure for PHA production from wastewater using microalgae/bacteria consortia. The use of mixed culture systems to produce PHAs from wastewater provides low cost production systems yielding co-polymers with useful mechanical properties. However, the challenges involved in the purification of the PHA from such a complex mix are significant. Biotrend is currently developing simple, low-cost and environmentally friendly processes, that can be easily plugged in existing wastewater treatment plants, for the purification of PHAs with different specifications.
