Volatile fatty acid from acidogenesis of organic waste are new range of platform chemicals with potential to replace the fossil-fuel derived compounds. The wide range applications of VFA demands, purified product through specific separation and recovery processes. This paper reviews the downstream processing of VFA pertaining to adsorption, gas stripping, liquid-liquid extraction and membrane separation. Influential parameters in each process are discussed from the perspective of mechanism of separation. A trade-off between selectivity and efficiency (process and energy) exists with each process. The review highlights the need for extensive research in process intensification specific for VFA separation/recovery processes. In-situ separation and recovery of VFA from waste water, and its use as carbon source on-site will help in lowering the C-footprint values as well as GHG emissions.

来自有机废物酸化作用的挥发性脂肪酸是一系列新的平台化学品，具有替代化石燃料衍生化合物的潜力。VFA 的广泛应用要求通过特定的分离和回收过程纯化产品。本文综述了 VFA 的下游工艺，涉及吸附、气提、液液萃取和膜分离。从分离机理的角度讨论了每个过程中的影响参数。每个过程都存在选择性和效率（过程和能量）之间的权衡。该评论强调需要对 VFA 分离/回收过程特定的过程强化进行广泛研究。从废水中原位分离和回收 VFA，
