Investigating the Adsorption Effect of Biochar on Microplastic Pollutants in Soil

This study reviews how biochar can adsorb and remove microplastics from contaminated soil through physical and chemical mechanisms. Researchers found that biochar's high surface area and functional groups are key factors in its microplastic adsorption capacity, and that acidic soil conditions improve removal efficiency. The findings suggest biochar application could be a practical approach for addressing microplastic pollution in agricultural soils.

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.

Biochar and organic fertilizer applications enhance soil functional microbial abundance and agroecosystem multifunctionality

A long-term field study found that adding biochar (a charcoal-like material) and organic fertilizer to farm soil significantly boosted beneficial soil microbes involved in nutrient cycling and improved overall ecosystem health by up to 30%. While not directly about microplastics, biochar has been shown in other studies to bind microplastics and reduce their movement through soil, making this approach potentially beneficial for both soil productivity and microplastic mitigation on farms.

The 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.
