Treatment of municipal and industrial wastewaters for environmental protection is largely conducted using biological processes. Biological wastewater treatment employs microorganisms, mainly bacteria, for the removal of contaminants. Nowadays, the treatment of wastewaters and organic residuals is also being considered for the recovery of valuable renewable resources. How can we combine the production of completely biodegradable plastics with wastewater treatment? How can microorganisms treat organic wastes and at the same time produce bioplastics? Are there such technologies available in Sweden? When can we expect this to happen in reality and where? These types of questions will be addressed by Fernando Morgan-Sagastume, researcher and a newly appointed Docent at Luleå University of Technology.
