Process Systems Engineering (PSE) could play a pivotal role towards this transition. As such, we present our novel framework along with an indicative case study . First, we introduce CE assessment metrics for evaluating different aspects of CE at various levels. This is vital for effective decision making, and benchmarking, but it needs to be conducted holistically. Having established the key assessment metrics, then superstructure optimization is used to holistically evaluate alternative pathways for the transition from a linear to a circular economy. A techno-economic feasibility analysis of these pathways at a large scale through modeling and optimization will be also presented. Finally, a superstructure representation of the supply chain of coffee is presented, that involves alternative pathways for coffee harvesting and processing, waste utilization, product distribution and new/alternative products introduction. This analysis, in conjunction with feedback from experimentalists lead to the identification of the optimum CE supply chain for coffee.
