The width of GGE and CO 2 flows are proportional to energy and mass flows, respectively. The capital cost is expressed in US$ Mg -1 for a 2,000 Mg day -1 biorefinery, and the operational cost is in units of US$ Mg -1 biomass processed. Green boxes show capital costs (CAPEX) and orange boxes show operational costs (OPEX), with details in Supplementary Table 1.
