Water is a valuable natural resource, which plays a crucial role in ecological survival as well as economic progress. However, the water quality has deteriorated in recent years as a result of urbanization, industrialization and human activities due to the uncontrolled release of industrial wastes, which can be extremely carcinogenic and non-degradable, in air, water and soil bodies. Such wastes showed the presence of organic and inorganic pollutants in high dosages. Heavy metals are the most obstinate contaminants, and they can be harmful because of having a variety of detrimental consequences to the ecosystem. The existing water treatment methods in many situations may not be sustainable or effective because of their high energy requirements and ecological impacts. In this review, state-of-the-art water treatment methods for the elimination of heavy metals with the help of protein nanofibrils are covered featuring a discussion on the strategies and possibilities of developing protein nanofibrils for the active elimination of heavy metals using kitchen waste as well as residues from the cattle, agriculture, and dairy industries. Further, the emphasis has been given to their environmental sustainability and economical aspects are also discussed.
水是一种宝贵的自然资源，它在生态生存和经济发展中都起着至关重要的作用。然而，近年来，由于城市化、工业化和人类活动的失控排放，工业废物在空气、水和土壤中释放，这些废物具有极强的致癌性和不可降解性，导致水质恶化。这些废物中含有高剂量的有机和无机污染物。重金属是最顽固的污染物，它们可能是有害的，因为它们会对生态系统造成多种不利的后果。在许多情况下，现有的水处理方法可能不可持续或无效，因为它们需要大量的能源，并且对生态有影响。在这篇综述中，介绍了利用蛋白纳米纤维去除重金属的最新水处理方法，讨论了利用厨房废物以及牛、农业和奶制品工业的残渣开发蛋白纳米纤维来主动去除重金属的策略和可能性。此外，还强调了它们的环境可持续性和经济性方面。
