Bi-dimensional sustainability analysis of a multi-feed biorefinery design for biofuels co-production from lignocellulosic residues and agro-industrial wastes

According to the bi-dimensional sustainability method employed in this work, the most important sustainability indicators were the End-use Energy Ratio (EER) for the environmental domain and Yield together with Total Production Cost (TPC) per energy unit produced for the economic domain. MPB10 scored 6% and 18% higher values for the first two indicators than its SPB counterpart with the added benefit of solving a severe environmental pollution problem. Nevertheless, MPB10 TPC per energy-unit and per litre of bioethanol are 6% and 30% higher than SPB, respectively.
