ClearHow 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.
Exploring the potential of biochar for the remediation of microbial communities and element cycling in microplastic-contaminated soil
Scientists found that adding biochar (a charcoal-like material made from plant waste) to soil contaminated with microplastics helped restore healthy microbial communities and nutrient cycling. The biochar reversed negative effects that microplastics had on soil chemistry, including nitrogen and phosphorus availability. This suggests biochar could be a practical tool for repairing farmland damaged by microplastic pollution.

Researchers found that adding biochar (a charcoal-like soil additive) to soil contaminated with microplastics helped improve plant growth by restoring phosphorus cycling. The microplastics disrupted soil microbe communities, but biochar treatment shifted these communities in beneficial ways. This suggests biochar could be a practical tool for farming in soils contaminated with plastic pollution.
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 was applied to microplastic-contaminated agricultural soil under different moisture conditions, with results showing that biochar improved soil chemical properties and shifted microbial communities in ways that partially offset microplastic-induced degradation. The study suggests biochar as a practical soil amendment to mitigate microplastic impacts in farming systems.
Effects of biochar amendment on bacterial communities and their function predictions in a microplastic-contaminated Capsicum annuum L. soil
Researchers investigated how adding biochar to soil contaminated with microplastics affects bacterial communities during pepper plant growth. They found that biochar amendment helped restore bacterial diversity and shifted community composition toward beneficial species, counteracting some of the negative effects of microplastic contamination. The study suggests that biochar could be a practical soil management tool for supporting microbial health in plastic-polluted agricultural systems.
Biochar-amended soil can further sorb atmospheric CO2 for more carbon sequestration
Researchers found that adding biochar to soil not only stores carbon but also helps the soil absorb additional carbon dioxide from the atmosphere through mineral reactions. While not directly about microplastics, biochar-amended soils could offer dual benefits by both sequestering carbon and potentially trapping microplastics, since biochar has been shown to adsorb plastic particles. This approach could address both climate change and plastic pollution in agricultural settings.
Biochar mitigates microplastic‐induced destabilization of soil organic carbon via molecular recalcitrance and microbial process regulation
Biochar amendments to soil were shown to offset the destabilizing effects that microplastics have on soil aggregate structure. The finding suggests that biochar could be a practical soil amendment to counteract microplastic-driven soil degradation in contaminated agricultural lands.

Researchers tested whether adding biochar to soil could reduce the harmful effects of PVC microplastic contamination on plant growth and soil health. They found that biochar amendment increased plant biomass, restored soil enzyme activity, and boosted beneficial microbial populations that had been suppressed by the microplastics. The study suggests that biochar could serve as a practical tool for rehabilitating agricultural soils contaminated with plastic particles.
