ClearThe Removal and Mitigation Effects of Biochar on Microplastics in Water and Soils: Application and Mechanism Analysis
This review examines how biochar can be used to both remove microplastics from water and mitigate their harmful effects in soils. Researchers found that woody biochar was the most effective type for adsorbing microplastics, while also helping to restore soil enzyme activities and microbial communities disrupted by plastic contamination. The study calls for further research into optimizing biochar applications and understanding the long-term environmental implications of biochar-microplastic interactions.

How biochar works, and when it doesn't: A review of mechanisms controlling soil and plant responses to biochar
This comprehensive review synthesizes 20 years of research on biochar, a charcoal-like material made from organic waste that can improve soil health and reduce pollution. Biochar can reduce plant uptake of heavy metals by 17-39% and increase nutrient availability, making it potentially useful for cleaning up microplastic-contaminated soils. While not directly about microplastics, the findings are relevant because biochar could help mitigate the effects of soil pollutants that microplastics carry and concentrate.

Advances and prospects of biochar in improving soil fertility, biochemical quality, and environmental applications
This review examines how biochar, a charcoal-like material made from organic waste, can improve soil health and clean up pollutants including microplastics. Biochar's ability to absorb and trap contaminants makes it a promising tool for reducing microplastic pollution in agricultural soil. The findings suggest biochar could help limit the amount of microplastics that enter the food chain through crops grown in contaminated soil.
Biochar-based adsorption technologies for microplastic remediation in aquatic ecosystems
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.
