Plastic pollution is a global concern and a challenge to the society and scientific community. What's more serious is the degradation of large plastics into micro (MPs) and nanoplastics (NPs). MPs and NPs are emerging contaminants, which have been proved to be toxic to living organisms. Not only this, but most recent studies have indicated their role to act as potential vectors for other contaminants in the environment. Hence the remediation of MPs and NPs from the environment is the need of the hour. In this study, a common agricultural waste sugarcane bagasse has been converted into biochar by pyrolyzing at different temperatures i.e., 350, 550 and 7500C (BC-350, BC-550 and BC-750 respectively) and utilized for the remediation of NPs from aqueous environment. BC-750 showed ¿98% removal of NPs unlike other two composites BC-550 and BC-350, which showed
