Table 2 Activity parameters for conversion plants in the regional foreground. Model plant concepts representative of the region were developed in collaboration with the German Biomass Research Centre (DBFZ) [64]. All flows unless otherwise stated are kg/MJ biodiesel produced, values have been rounded up to the nearest decimal place
