On Monday, December 19^th 2022, the students of ‘Environmental engineering: methods, solutions and technologies for sustainable agriculture’ course visited the ‘Rozzi’ laboratory, where the researchers of Fabbrica della Bioenergia showed them the ongoing research activities. The visit was organized as a route, named ‘THE CIRCULAR FARM‘, in which different options for treating waste in the view of recovering resources and generating a circular structure within the farm were shown. With the aim of highlighting the great opportunities deriving from the sector waste, both more consolidated solutions, such as the recovery of energy or biomethane via anaerobic digestion, and emerging solutions, such as for example the recovery of bioplastics or biostimulants from phototrophic biomass, were presented. The interactive activities were managed by the young researchers of the group and took place in a sequence of five thematic stages, each dedicated to a resource recovery solution: (1) anaerobic co-digestion and biogas upgrade, (2) fermentation acidogenic for the production of volatile fatty acids, (3) nutrient recovery, (4) resource recovery with microalgae, (5) resource recovery with purple phototrophic bacteria.
