Recovering waste solvent for reuse presents an excellent alternative to improving the greenness of industrial processes. Implementing solvent recovery practices in the chemical industry is necessary, given the increasing focus on sustainability to promote a circular economy. However, the systematic design of recovery processes is a daunting task due to the complexities associated with waste stream composition, techno-economic analysis, and environmental assessment. Furthermore, the challenges to satisfy the desired product specifications, particularly in pharmaceuticals and specialty chemical industries, may also deter solvent recovery and reuse practices. To this end, this review presents a systems-level approach including various methodologies that can be implemented to design and evaluate efficient solvent recovery pathways.

回收废溶剂以供再利用是改善工业过程绿色性的绝佳替代方案。鉴于越来越关注可持续性以促进循环经济，在化工行业实施溶剂回收实践是必要的。然而，由于与废物流组成、技术经济分析和环境评估相关的复杂性，回收过程的系统设计是一项艰巨的任务。此外，满足所需产品规格的挑战，尤其是在制药和特种化工行业，也可能阻碍溶剂回收和再利用实践。为此，本综述提出了一种系统级方法，包括可用于设计和评估有效溶剂回收途径的各种方法。
