Bio-based volatile fatty acid (VFA) production from waste-stream is getting attention due to increasing market demand and wide range usage area as well as its cost-effective and environmentally friendly approach. The aim of this paper is to give a comprehensive review of bio-based VFA production and recovery methods and to give an opinion on future research outlook. Effects of operation conditions including pH, temperature, retention time, type of substrate and mixed microbial cultures on VFA production and composition were reviewed. The recovery methods in terms of gas stripping with absorption, adsorption, solvent extraction, electrodialysis, reverse osmosis, nanofiltration, and membrane contractor of VFA were evaluated. Furthermore, strategies to enhance bio-based VFA production and recovery from waste streams, specifically, in-line VFA recovery and bioaugmentation, which are currently not used in common practice, are seen as some of the approaches to enhance bio-based VFA production.

由于市场需求的增长和广泛的使用领域，以及其具有成本效益和环境友好的方法，从废物流中生产生物基挥发性脂肪酸（VFA）备受关注。本文的目的是对生物基VFA的生产和回收方法进行全面的综述，并对未来的研究前景提出意见。考察了操作条件（包括pH，温度，保留时间，底物类型和混合微生物培养物）对VFA产生和组成的影响。评价了通过VFA的吸收，吸附，溶剂萃取，电渗析，反渗透，纳滤和膜收缩器进行气提的回收方法。此外，还应采取一些策略来增强生物基VFA的生产以及从废物流中回收，特别是，
