The objective of this review is to discuss the sustainable application of microalgae in phenols degradation, with a special emphasis on the enzymes involved in this bioprocess and the factors affecting the success of PPPIE phycoremediation. Moreover, it confers the microalgae bioenergetic strategies to degrade different forms of phenols in PPPIE. It also points out the advantages of the latest application of bacteria, fungi, and microalgae as microbial consortia in phenols biodegradation. Briefly, phycoremediation of PPPIE consumes carbon dioxide emitted from petro‐industries for; valorization of the polluted water to be reused and production of algal biomass which can act as a source of energy for such integrated bioprocess. Besides the harvested algal biomass can feasibly produce; third‐generation biofuels, biorefineries, bioplastics, fish and animal feed, food supplements, natural dyes, antioxidants, and many other valuable products. Consequently, this review precisely confirms that the phycoremediation of PPPIE is a win‐win process for a green environment and a sustainable future. Thus, to achieve the three pillars of sustainability; social, environmental, and economic; it is recommendable to integrate PPPIE treatment with algal cultivation. This integrated process would overcome the problem of greenhouse gas emissions, global warming, and climate change, solve the problem of water‐scarce, and protect the environment from the harmful negative impacts of PPPIE.en-USPhycoremediationPetro‐IndustrialEnergyBioproductsArticlehttps://doi.org/10.1111/jam.14989
