Relation between greenhouse gas emissions and economic profit for different configurations of biogas value chains: A case study on different levels of sector integration

The results show that a broad integration of sectors is beneficial in terms of reduction of greenhouse gases. There is, however, a negative coherency between reduction of greenhouse gases and economic profitability when it comes to different levels of sector integration. The calculations showed that only a small increase in economic incentives are necessary to make biomethane for transport purposes as profitable as the reference. Inclusion of the agricultural sector into waste-based biogas value chains appears to be challenging and is likely to require greater incentives.
