摘要：

This work assesses the economic and social performance of energy production through two biorefineries based on Coffee Cut-Stems (CCS). The economic assessment was carried out to determine the effect of the processing scale on the Net Present Value (NPV). The social analysis was performed to evaluate the social effects of the possible biorefineries implementation. Thus, a set of indicators were calculated as metrics of the social impact. The economic assessment shows that the base case biorefinery is infeasible in any processing scale. Meanwhile, the alternative solution I presents a positive economic behavior at scales higher than 17 ton h−1, this configuration presents a positive economic behavior. The social assessment indicates that the first biorefinery is infeasible because the astronomic resources requirements to reach economic feasibility. Meanwhile, the second biorefinery does not have high social risk in most of the social indicators being best configuration from the economic and social perspectives. © 2020 Elsevier Ltd
