Mismanaged plastics, upon entering the environment, undergo degradation through physicochemical and/or biological processes. This process often results in formation of microplastics (MPs), most prevalent form plastic debris (<1 mm). MPs pose severe threats to aquatic and terrestrial ecosystems, necessitating innovative strategies for effective remediation. Some photosynthetic microorganisms can degrade but there lacks a comprehensive review. Here we examine specific role photoautotrophic water soil environments biodegradation focussing on their unique ability grow persistently diverse polymers under sunlight. Notably, these cells utilise light CO2 produce valuable compounds such as carbohydrates, lipids, proteins, showcasing multifaceted environmental benefits. We address key scientific questions surrounding utilisation nanoplastics (NPs) bioremediation, discussing potential engineering enhanced efficacy. Our review highlights significance alternative biomaterials exploration strains expressing enzymes, polyethylene terephthalate (PET) hydrolases, conjunction with microalgal cyanobacterial metabolisms. Furthermore, delve into promising photo-biocatalytic approaches, emphasising coupling sunlight exposure. The integration microalgal-bacterial consortia is explored biotechnological applications against NPs pollution, synergistic effects wastewater treatment absorption nitrogen, heavy metals, phosphorous, carbon. In conclusion, this provides overview current state research use bioremediation. It underscores need continued investigation development approaches tackle global issue pollution ecosystems.

Abstract The escalating accumulation of plastic waste has been developed into a formidable global environmental challenge. Traditional disposal methods such as landfilling and incineration not only exacerbate degradation by releasing harmful chemicals greenhouse gases, but also squander finite resources that could otherwise be recycled or repurposed. Upcycling is kind recycling technology converts high‐value helps to avoid resource pollution. Electrocatalytic upcycling emerges novel distinguished its mild operational conditions, high transformation efficiency product selectivity. This review commences with an overview the employed in management respective advantages inherent limitations are delineated. different types upcycled electrocatalytic strategy then discussed process examined together mechanisms underlying upcycling. Furthermore, structure‐activity relationships between electrocatalysts performance elucidated. aims furnish readers comprehensive understanding techniques for provide guidance design towards efficient transformation.
