The main objective of this study is the potential evaluation of obtaining bioplastics through biodegradable polyesters synthesized by bacteria, present in the anaerobic treatment of urban and industrial wastewater, which have a series of characteristics to consider as their processing as material bioplastic In Asturias, more than 70,000 tons of sludge are produced and, by applying circular economy criteria and technologies for the production of bioplastics from wastewater, a synergy could be

... ained that would allow the reuse of sludge by valorization as raw material. to produce bioplastics. This valorization can be carried out mainly through the combination of two technologies, on the one hand, anaerobic fermentation to produce volatile fatty acids and on the other the generation of bacterial populations that produce Polyhydroxyalkanoates (PHA's). The PHAs are obtained from the microorganisms present in the sludge generated in the wastewater treatment process.
