Guiding Innovations and Value-Chain Improvements Using Life-Cycle Design for Sustainable Circular Economy

6 pagesDate: March 12, 2022


While the current linear state of the economy has led to large scale natural-resource exploitation and pollution, circular economy can also lead to unexpected harm to environmental sustainability. Thus, there is a need to design product value-chains to achieve a Sustainable and Circular Economy (SCE). Previous work has focused on developing a systems engineering framework using life-cycle assessment with ‘superstructure’ network optimization to find optimal value-chain pathways while considering product life-cycles. However, the role of innovations in the form of novel technologies, societal action and new policy action has become increasingly crucial to establish SCE. In this work, we propose a sensitivity optimization framework to find the most attractive innovation directions within the value-chain using parameter perturbations as additional decision variables over pathway choice. The objectives include maximizing circularity and minimizing carbon dioxide emissions. We quantify the trade-off between these objectives and determine win-win innovative solutions using pareto and perturbation fronts. The method is demonstrated for an illustrative example, and its applicability to real value-chain networks has been probed.
