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提高工业生产过程绿色度的一个极佳选择。鉴于对可持续发展以促进循环经济的关注度日益提高，在化学工业中实施溶剂回收措施很有必要。然而，回收过程的系统设计是一项艰巨的任务，因为它涉及废物流组成、技术经济分析和环境评估等方面的复杂性。此外，满足所需产品规格面临的挑战，尤其是在制药和特种化学工业中，也可能阻碍溶剂回收和再利用措施的实施。为此，本综述提出了一种系统层面的方法，包括各种可用于设计和评估高效溶剂回收途径的方法。
