19 Department of Biotechnology BIOGAS PRODUCTION -AN IMPORTANT TOOL IN ENVIRONMENTAL PROTECTION

20 Department of Biotechnology Målsättning: minska utsläppen av växthusgaser med 60% till 2050 Kyotoprotokollet: 5% till 2010 Metanproduktion från odlingsrester får dubbel effekt:  Ersätt 11 TWh fossila bränslen: 3,2 Mton CO 2 (6%)  Förhindra läckage av metan: 1,3-3,7 Mton (2-8%)

21 Department of Biotechnology What is lacking to make biogas an attractive alternative? Research Simple, cost efficient digesters Economy The biogas producer should get paid for the environmental benifits Education A strategy for education of future entrepreneurs

22 Department of Biotechnology ANTHONY MSHANDETE - Anaerobic digestion of agroindustrial waste and technology transfer to developing countries. JIM ANDREASSON - collaborative project with NSR on intensified hydrolysis of municipal waste. DORES CIRNE - lipid degradation, lipase producing isolates, microbial dynamics in hydrolysis/methanogenesis MATTIAS SVENSSON - single stage digestion of dry crop residues IRENE BOHN – FISH quantification and low temperature digestion WILSON PARAWIRA – high rate digestion of agroindustrial residues ANNI LEHTOMÄKI – anaerobic digestion of energy crops SANKAR MARICHAMY – isolation and characterisation of cultures for hydrolysis, solvent production and enzyme production. JING LIU - instrumentation and control, development of sensors and improved control algorithms MARIKA MURTO – FISH, surfactants and UASB, biogas upgrading LOVISA BJÖRNSSON – microbiology, hydrogen sensor technology
