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.

Soil aggregation alterations under soil microplastic and biochar addition and aging process
An eight-month experiment found that polyethylene and polypropylene microplastics disrupted soil structure by breaking apart soil clumps, and this damage worsened as the plastics aged over time. Surprisingly, adding biochar, which is often proposed as a soil improvement, actually made some of the microplastic damage worse for certain soil aggregate sizes. This research shows that microplastic contamination in agricultural soil can degrade soil health in ways that may be difficult to reverse.
