Plastic waste discarded into aquatic environments gradually degrades smaller fragments, known as microplastics (MPs), which range in size from 0.05 to 5 mm. The ubiquity of MPs poses a significant threat ecosystems and, by extension, human health, these particles are ingested various marine organisms including zooplankton, crustaceans, and fish, eventually entering the food chain. This contamination threatens entire ecological balance, encompassing safety health systems. Consequently, developing effective MP removal technologies has emerged critical area research. Here, we summarize mechanisms recently reported strategies for removing ecosystems. Strategies combining physical chemical pretreatments with microbial degradation have shown promise decomposing MPs. Microorganisms such bacteria, fungi, algae, specific enzymes being leveraged remediation efforts. Recent advancements focused on innovative methods membrane bioreactors, synthetic biology, organosilane-based techniques, biofilm-mediated remediation, nanomaterial-enabled strategies, nano-enabled demonstrating substantial potential enhance efficiency. review aims stimulate further innovation methods, promoting environmental social well-being.
