Cover Story: The University of Perugia, Department of Engineering is managing different activities in the field of biogas production through anaerobic digestion. The Department is coordinating a LIFE 2016 project named i-REXFO on waste food reduction and reuse. In addition to this, the University of Perugia has tested an incubation system coupled to an anaerobic digestion reactor to enhance biogas and methane production. This underlines even more the importance of pretreatment on feedstock to promote anaerobic digestion process intensification (intended as all the techniques which can increase process efficiency and sustainability).View this paper.
