Environmental Engineering

The laboratory's research lines are focused on the following topics:

  • Study of biotechnological processes (microalgae-bacteria) for the purification of wastewater/anaerobic supernatants from the municipal and agro-industrial sector (winery) aimed at energy recovery (biodiesel) and added-values products (biostimulants, fertilizers, feeding supplement) in a view of circular economy;
  • Study and optimization of biological processes (dark-fermentation and anaerobic digestion) for the conversion of municipal organic waste into energy (bio-hydrogen, biogas, biomethane) and matter (fertilizers, chemical building-blocks, etc.);
  • Development of innovative anaerobic of moving bed bioreactor (MBBR) processes electrochemically assisted for the treatment of high-salinity industrial wastewater (tannery sector) for the production of biomethane and chemical building blocks;
  • Biotechnological processes utilizing aerobic mixed microbial cultures (MMC) for the treatment of civil and/or industrial wastewater and municipal solid waste, aimed at their disposal and their conversion of organic carbon into biodegradable polymers (e.g. polyhydroxyalkanoates).
