Economic growth and the rapid increase in the world population has led to a greater need for natural resources, which in turn, has put pressure on said resources along with the environment. Water, food, and energy, among other resources, pose a huge challenge. Numerous essential resources, including organic substances and valuable nutrients, can be found in wastewater, and these could be recovered with efficient technologies. Protein recovery from waste streams can provide an alternative resource that could be utilized as animal feed. Membrane separation, adsorption, and microbe-assisted protein recovery have been proposed as technologies that could be used for the aforementioned protein recovery. This present study focuses on the applicability of different technologies for protein recovery from different wastewaters. Membrane technology has been proven to be efficient for the effective concentration of proteins from waste sources. The main emphasis of the present short communication is to explore the possible strategies that could be utilized to recover or restore proteins from different wastewater sources. The presented study emphasizes the applicability of the recovery of proteins from various waste sources using membranes and the combination of the membrane process. Future research should focus on novel technologies that can help in the efficient extraction of these high-value compounds from wastes. Lastly, this short communication will evaluate the possibility of integrating membrane technology. This study will discuss the important proteins present in different industrial waste streams, such as those of potatoes, poultry, dairy, seafood and alfalfa, and the possible state of the art technologies for the recovery of these valuable proteins from the wastewater.
经济增长和世界人口的快速增长导致对自然资源的需求更大，这反过来又给资源和环境带来了压力。水、食物和能源等资源面临巨大挑战。废水中存在许多有价值的营养物质和有机物质等重要资源，可以通过高效技术进行回收。从废水中回收蛋白质可以提供一种替代资源，可以用作动物饲料。膜分离、吸附和微生物辅助蛋白质回收已被提议作为可用于上述蛋白质回收的技术。本研究侧重于不同技术从不同废水中回收蛋白质的适用性。膜技术已被证明可有效从废物中浓缩蛋白质。本简短交流的主要重点是探讨可用于从不同废水源中回收或恢复蛋白质的可能策略。本研究强调了使用膜从各种废水源中回收蛋白质的适用性以及膜工艺的结合。未来的研究应侧重于可以帮助从废物中高效提取这些高价值化合物的新技术。最后，本简短交流将评估整合膜技术的可能性。本研究将讨论不同工业废水中存在的重要蛋白质，如土豆、家禽、乳制品、海鲜和苜蓿的蛋白质，以及从废水中回收这些有价值蛋白质的可能的最新技术。
