Large Scale Production Of Polyhydroxyalkanoates (Phas) From Wastewater: A Study Of Techno-Economics, Energy Use And Greenhouse Gas Emissions

Cora Fernandez Dacosta, John A. Posada & Andrea Ramirez
The biodegradable family of polymers
polyhydroxyalkanoates is an interesting substitute for convectional
fossil-based plastics. However, the manufacturing and environmental
impacts associated with their production via intracellular bacterial
fermentation are strongly dependent on the raw material used and on
energy consumption during the extraction process, limiting their
potential for commercialization. Industrial wastewater is studied in
this paper as a promising alternative feedstock for waste valorization.
Based on results from laboratory and pilot-scale experiments, a
conceptual process...
