The quest for a chemical surfactant substitute has been fuelled by increased environmental awareness. The benefits that biosurfactants present like biodegradability, and biocompatibility over their chemical and synthetic counterparts has contributed immensely to their popularity and use in various industries such as petrochemicals, mining, metallurgy, agrochemicals, fertilizers, beverages, cosmetics, etc. With the growing demand for biosurfactants, researchers are looking for low-cost waste materials to use them as substrates, which will lower the manufacturing costs while providing waste management services as an add-on benefit. The use of low-cost substrates will significantly reduce the cost of producing biosurfactants. This paper discusses the use of various feedstocks in the production of biosurfactants, which not only reduces the cost of waste treatment but also provides an opportunity to profit from the sale of the biosurfactant. Furthermore, it includes state-of-the-art information about employing municipal solid waste as a sustainable feedstock for biosurfactant production, which has not been simultaneously covered in many published literatures on biosurfactant production from different feedstocks. It also addresses the myriad of other issues associated with the processing of biosurfactants, as well as the methods used to address these issues and perspectives, which will move society towards cleaner production.
人们日益增强的环保意识推动了寻找化学表面活性剂替代品的研究。生物表面活性剂具有可生物降解性和生物相容性等优点，优于其化学和合成对应物，这极大地促进了它们在石化、采矿、冶金、农化、肥料、饮料、化妆品等各种行业的应用和普及。随着对生物表面活性剂需求的不断增长，研究人员正在寻找低成本的废料来作为其底物，这将降低制造成本，同时提供废物管理服务作为附加效益。使用低成本的底物将显著降低生物表面活性剂的生产成本。本文讨论了各种原料在生物表面活性剂生产中的应用，这不仅降低了废物处理的成本，还为销售生物表面活性剂提供了获利机会。此外，它还包括了将城市固体废物作为生物表面活性剂生产可持续原料的最新信息，这在许多关于不同原料生产生物表面活性剂的已发表文献中并未同时涵盖。它还解决了与生物表面活性剂加工相关的众多其他问题，以及用于解决这些问题的方法和观点，这将推动社会向清洁生产迈进。
