【 摘 要 】

Developing a biobased chemical industry that copes with the current environmental challenges relies on under-standing the influence of the different stages of the value chain on economic and environmental performance. This paper investigates the use of a life cycle optimization framework to assess trade-offs between environmental and economic criteria for designing supply chains for biobased polyethylene terephthalate as a case study. A multi-objective optimization model was formulated to account for the environmental impacts (through life cycle assessment) and total costs (through life cycle costing) of the case study. High environmental priority (w = 0.9) in the design of the supply chain resulted in environmental gains (in 8 out of 9 midpoint indicators) with low increments (<10 %) of the total supply chain costs. The hotspot analysis supported identifying the stages (processing plants) of the supply chain where environmental and economic improvements are required. As the environmental priority increased, a rebound effect was evidenced where the mitigation of the environ-mental impact in different processing plants negatively affected the economic performance of other processing plants. Therefore, close collaboration with all value chain actors is required to achieve the most optimal configu-ration for supply chains of biobased polyethylene terephthalate.(c) 2022 The Author(s).
