Biochar applications in microplastic and nanoplastic removal: mechanisms and integrated approaches
AI summary Read the abstract
This review explores how biochar, a charcoal-like material made from organic waste, can be used to filter microplastics and nanoplastics out of water. Researchers found that biochar works through several mechanisms and becomes even more effective when combined with other water treatment technologies. The study suggests biochar-based approaches could be a practical, low-cost strategy for tackling plastic pollution in water systems.
This review explores biochar's potential for removing microplastics and nanoplastics from water, discussing various mechanisms and the benefits of combining biochar with other water treatment technologies.

Engineered biochar for microplastic remediation in aquatic environments: Interfacial mechanisms, modification strategies, and future perspectives
AI summary Read the abstract
Tiny plastic particles are showing up everywhere in our water, and current treatment plants can only filter out 40-78% of them, meaning the rest ends up in our environment and potentially our bodies. This review paper highlights biochar—a charcoal-like material made from plant waste—as a cheap, eco-friendly filter that can be specially engineered to capture up to 99% of microplastics from water. While promising, scientists still need to standardize these methods and test them at larger scales before this becomes a widespread solution for cleaner drinking water.

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.
