(syllabus)
- The concept of Bio-refinery and reasons that will address the exploitation of waste, by-products, wastes and effluents from different sectors, particularly the food industry. Context in which the bio-refineries are important: the so-called Green Economy and Circular Economy. - Environmental contamination, sources of pollution and treatment opportunities and simultaneous valorisation of waste, effluent and by-products: aerobic treatment of waste water (activated sludge systems, tricking filters, rotating discs, etc.; plant dysfunctions; removal of nitrates and phosphates; treatment of residual sludge); anaerobic treatment of wastewater and solid residues (biochemistry; microorganisms involved; biodigestors; biogas). - Emerging contaminants (e.g. antibiotics) and antibiotic resistance genes: possible technological solutions. - Guidelines in the choice of strategies aimed at the recovery of renewable resources and the production of molecules at medium- and high-added value. - Production of soil/fertilizer, plant growth promoting and biocontrol agents from waste: composting and control of odor emissions (biofiltration). - Production of bioadsorbenti, energy and biofuels from waste: pyrolysis, gasification, microbial fermentations. - Recovery of fine-chemicals and bioactive molecules (antioxidants, multifunctional food ingredients, etc.). - Microbial production of microbial biomass, bio-molecules and enzymes. Laboratory activities will be conducted on methods of quantification of the pollutant rate of wastes (BOD, COD, etc.) and observation of active sludge. A didactic visit will take place at a biorefinery company.
