The era of rapid industrialization succeeded by a shift in organizational focus on research and technology development which has fueled many industries along with the dairy industry to grow at an exponential rate. The dairy industry has achieved remarkable growth in the last decade in India. Waste produced by dairy industry consists of a high organic load thus cannot be discharged untreated. Even though treatment and management of waste are well documented, but the main problem is concerned with sludge produced after treatment. There is a gap in the application of various methods for effective treatment of the waste, hence there is a need for technology-oriented research in this area because of a paradigm shift in perspectives towards sustainable management of waste to recover value added products including energy as energy demand is also rising. Sludge which is generally land spread can also be used for energy generation. This paper discusses the environmental effects of waste generated due to dairy industrial activities; various methods used for the advanced treatment of dairy waste. This review article aims to present and discuss the state-of-art information for recovery of value-added products (single cell protein, biofertilizers, biopolymers and biosurfactants) from dairy waste with emphasis on integration of technologies for environmental sustainability. This paper also includes challenges and future perspectives in this field.

乳制品废弃物的增值:增值产品的综合方法

快速工业化时代的成功是组织重点转向研究和技术开发,这推动了乳制品行业等许多行业的指数级增长。印度的乳制品行业在过去十年中取得了显着的增长。乳制品行业产生的废物含有很高的有机负荷,因此不能未经处理就排放。尽管废物的处理和管理已有详细记录,但主要问题在于处理后产生的污泥。在有效处理废物的各种方法的应用方面存在差距,因此需要在该领域进行以技术为导向的研究,因为废物可持续管理的观点发生了范式转变,以回收包括能源在内的增值产品能源需求也在上升。通常散布在土地上的污泥也可用于发电。本文讨论了乳制品工业活动产生的废物对环境的影响;用于深度处理乳品废物的各种方法。本文旨在介绍和讨论从乳制品废物中回收增值产品(单细胞蛋白、生物肥料、生物聚合物和生物表面活性剂)的最新信息,重点是环境可持续性技术的整合。本文还包括该领域的挑战和未来前景。
