Konstantinos Pispas is a Predoctoral Researcher in environmental biotechnology and sustainable wastewater treatment. He has research experience in biotechnological processes for wastewater treatment and resource recovery. His research has focused on the production of polyhydroxyalkanoates (PHAs) bioplastics using cyanobacteria cultivated in agro-industrial effluents, with an emphasis on optimizing both upstream and downstream processes to enhance biomass productivity, pigment production, and PHA accumulation. Currently, his research focuses on the integration and upscaling of purple phototrophic bacteria (PPB)-based microbial electrochemical systems for sustainable wastewater treatment and resource recovery. He investigates the role of biochar in enriched PPB cultures for the treatment of domestic wastewater.
