ClearRole of biochar toward carbon neutrality
This review examines how biochar, a carbon-rich material made from plant waste, can help fight climate change by reducing greenhouse gas emissions across agriculture, energy, and construction. While not directly about microplastics, biochar is also used as an environmental cleanup tool that can adsorb pollutants from soil and water, including plastic particles.
Advancing modified biochar for sustainable agriculture: a comprehensive review on characterization, analysis, and soil performance
This review covers how biochar, a carbon-rich material made from organic waste, can be modified to improve soil health and crop growth. While not directly about microplastics, modified biochar has been studied as a potential tool for absorbing and immobilizing microplastics in contaminated soil. Understanding how to optimize biochar properties could help develop strategies for reducing microplastic uptake by food crops.
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.
Potential Role of Biochar on Capturing Soil Nutrients, Carbon Sequestration and Managing Environmental Challenges: A Review
This review summarizes how biochar, a charcoal-like material made from plant waste, can improve soil health, capture nutrients, and store carbon. Biochar is also being studied as a tool to absorb pollutants including microplastics from soil and water, making it relevant to efforts to reduce human exposure to plastic contamination in agriculture and the food chain.
Utilization of cotton byproduct-derived biochar: a review on soil remediation and carbon sequestration
This review examines how biochar made from cotton plant byproducts can be used to improve soil health and capture carbon dioxide. While not directly about microplastics, biochar has been shown in other studies to bind microplastics and reduce their mobility in soil. The use of agricultural waste-derived biochar for soil remediation could offer a dual benefit of improving crop productivity while helping to immobilize microplastic contaminants in farmland.
Biochar alters chemical and microbial properties of microplastic-contaminated soil
Researchers found that biochar amendments improved chemical and microbial properties of microplastic-contaminated soil, with effects varying by biochar type and water conditions, suggesting biochar as a potential remediation tool for plastic-polluted agricultural soils.
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.
Role of Biochar and Microbes in Remediation of Microplastics in Soil
This review examines how biochar and soil microbes can be combined to remediate microplastic-contaminated soils, synthesizing evidence for biochar's adsorption capacity and microbial degradation pathways that reduce microplastic persistence and toxicity.
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.
Influence of biochar and microplastics on microbial necromass accumulation and CO2 and N2O emission in a Calcaric Fluvisol
A 91-day soil experiment found that biochar reduced CO2 and N2O emissions, but the presence of microplastics partially counteracted these benefits, suggesting that plastic pollution can undermine soil carbon management strategies.
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.
Combined effect of biochar and soil moisture on soil chemical properties and microbial community composition in microplastic‐contaminated agricultural 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.
