Temperature-induced modifications in sugarcane bagasse derived biochar: A sustainable solution for nanoplastic remediation
AI summary Read the abstract
Researchers converted sugarcane agricultural waste into biochar at different temperatures and tested its ability to adsorb nanoplastics from water, finding that higher pyrolysis temperatures produced more effective adsorbents. Using agricultural waste-derived biochar to capture nanoplastics offers a sustainable, low-cost remediation approach.
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 Also see: https://micro2022.sciencesconf.org/427706/document

Biochar-based adsorption technologies for microplastic remediation in aquatic ecosystems
AI summary Read the abstract
This review examines the use of biochar, a carbon-rich material made from organic waste, as a tool for removing microplastics from water. Biochar can effectively adsorb microplastic particles due to its porous structure and surface chemistry, and it can be produced cheaply from agricultural waste. The technology shows promise as an affordable and sustainable approach to reducing microplastic contamination in waterways, though challenges remain in scaling it up for real-world water treatment.
