减缓气候变化和减少材料泄漏到环境中的紧迫性激发了大量的创新技术、供应链和政策行动。这些目标是减少温室气体排放，自然资源吸收，并使用循环战略将技术系统与基于化石的线性经济脱钩。工业和政府利益相关者热衷于根据其对可持续和循环经济的贡献范围对这些拟议的生态创新和新兴替代品进行排名，以实现全球变暖削减和污染缓解目标。我们描述了一种新的方法框架，它依赖于多目标优化的摇篮到摇篮的生命周期途径，从一个大型的数据库筛选概念生态创新和排名的基础上建立一个可持续的循环经济（SCE）的潜力。这种方法是实施一个激励性的案例研究，以评估众多的包装生态创新的基础上，他们的改进潜力和准备采用的杂货袋价值链网络。它表明，初步筛选步骤确定了10个最有前途的生态创新，从一个大的超集的替代品，如果开发和采用，可以帮助价值链过渡到未来的情景与净零排放和遵守回收和可再生内容的目标由美国塑料协定，但成本更高。
The urgency of action toward mitigating climate change and reducing material leakage into the environment is inspiring a plethora of innovative technologies, supply chains, and policy actions. These are targeted toward reducing greenhouse gas emissions, natural resource uptake, and decoupling technological systems from fossil-based linear economies using circularity strategies. Industrial and governmental stakeholders are keen to rank these proposed eco-innovations and emerging alternatives based on their scope of contributing to a sustainable and circular economy to meet global warming curtailment and pollution mitigation targets. We describe a novel methodological framework that relies on a multiobjective optimization of cradle-to-cradle life-cycle pathways to screen from a large database of conceptual eco-innovations and rank them based on their potential for establishing a Sustainable Circular Economy (SCE). This methodology is implemented for a motivating case study to evaluate numerous packaging eco-innovations based on their improvement potential and readiness for adoption within the grocery bags value-chain network. It is demonstrated that a preliminary screening step identifies the 10 most promising eco-innovations from a large superset of alternatives, which if developed and adopted can help transition the value chain to a future scenario with net-zero emissions and adherence to the recycled and renewable-content targets set by the United States Plastics pact but at a higher cost.
