Phycoremediation is gaining attention not only as a pollutant mitigation approach but also as one of the most cost-effective paths to achieve carbon neutrality. When compared to conventional treatment methods, phycoremediation is highly effective in removing noxious substances from wastewater and is inexpensive, eco-friendly, abundantly available, and has many other advantages. The process results in valuable bioproducts and bioenergy sources combined with pollutants capture, sequestration, and utilization. In this review, microalgae-based phycoremediation of various wastewaters for carbon neutrality and circular economy is analyzed scientometrically. Different mechanisms for pollutants removal and resource recovery from wastewaters are explained. Further, critical parameters that influence the engineering design and phycoremediation performance are described. A comprehensive knowledge map highlighting the microalgae potential to treat a variety of industrial effluents is also presented. Finally, challenges and future prospects for industrial implementation of phycoremediation towards carbon neutrality coupled with circular economy are discussed.

碳中和和循环经济的藻类修复:潜力、趋势和挑战



藻类修复不仅作为一种污染物缓解方法而受到关注,而且作为实现碳中和的最具成本效益的途径之一。与传统处理方法相比,藻疗在去除废水中的有害物质方面非常有效,而且价格低廉、环保、可用丰富,并且具有许多其他优势。该过程产生有价值的生物产品和生物能源,并结合污染物捕获、封存和利用。在这篇综述中,对各种废水进行基于微藻的藻类修复以实现碳中和和循环经济进行了科学计量分析。解释了从废水中去除污染物和回收资源的不同机制。此外,还描述了影响工程设计和藻修复性能的关键参数。还提供了一个全面的知识图谱,突出了微藻处理各种工业废水的潜力。最后,讨论了藻类修复工业实施碳中和结合循环经济的挑战和未来前景。
