Biogas, Biomethane and Digestate Potential of By-Products from Green Biorefinery Systems

Global warming and climate change are imminent threats to the future of humankind. A shift from current reliance on fossil fuels renewable energy is key mitigating impacts change. Biological raw materials residues can play a role in this transition through technologies such as anaerobic digestion. However, biological must also meet other existing food, feed material needs. Green biorefinery an innovative concept which green biomass, grass, processed obtain variety protein products, value-added co-products energy, helping many needs single source. In study, analysis has been conducted understand potential by-products residues, including grass whey, de-FOS whey press cake. Using digestion, biogas biomethane these samples have analyzed. An fertiliser resulting digestate undertaken. All feedstocks tested were found be suitable for production with most candidate yield 895.8 544.6 L/kg VS, respectively, followed by cake (597.4/520.3 VS 510.7/300.3 respectively). The results show considerable utilizing source production, even after several products co-produced.
