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.

Biochar and Microplastics Affect Microbial Necromass Accumulation and CO2 and N2O Emissions from Soil

Researchers investigated how biochar and polyethylene microplastics interact in soil and found that both reduced CO2 and N2O greenhouse gas emissions, though through different mechanisms. Microplastics decreased emissions primarily by reducing dissolved organic matter and bacterial biomass, while biochar suppressed nitrogen-cycling genes. When combined, microplastics in biochar-treated soil unexpectedly increased microbial necromass carbon by disrupting soil aggregates, revealing complex interactions between these two soil amendments.

Biochar-microplastics interaction modulates soil nitrous oxide emissions and microbial communities

Researchers examined how biochar interacts with conventional and biodegradable microplastics in soil to affect coriander growth, nitrous oxide emissions, and microbial communities. They found that biochar generally reduced soil nitrous oxide emissions, but this benefit was diminished or even reversed when certain microplastics were present. The study suggests that the combined use of biochar and plastic mulch in agricultural fields can produce unexpected effects on greenhouse gas emissions and soil microbiology.

Biochar Mitigates the Negative Effects of Microplastics on Sugarcane Growth by Altering Soil Nutrients and Microbial Community Structure and Function

Microplastic contamination in sugarcane-growing soils in China reduces crop biomass and degrades soil nutrients and microbial diversity. Adding biochar to microplastic-polluted soil helped offset these harms — restoring sugarcane growth, stabilizing soil pH, and improving bacterial community richness. The findings suggest biochar is a practical tool for rehabilitating agricultural land affected by plastic pollution.

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 as a Green Sorbent for Remediation of Polluted Soils and Associated Toxicity Risks: A Critical Review

This review examines biochar, a charcoal-like material made from organic waste, as a tool for cleaning up soil contaminated with heavy metals and organic pollutants. While biochar can effectively trap contaminants, the production process itself can create toxic byproducts like PAHs that may harm soil life. The research is relevant to microplastic pollution because biochar is being explored as a potential method to bind and reduce microplastic contamination in agricultural soils.

Co-application of organic fertilizer and biochar ameliorates the triple composite pollution of microplastics, antibiotic resistance genes, and heavy metals in soil

Agricultural soils are increasingly polluted by a troubling combination of heavy metals, microplastics, and antibiotic-resistant bacteria — and this five-year field study found that combining biochar with organic fertilizer significantly reduces all three types of contamination at once. The treatment worked by reshaping soil microbial communities in ways that suppressed antibiotic-resistant organisms while promoting microbes that break down plastics and immobilize metals. This approach offers a practical, field-tested strategy for cleaning up complex pollution in intensively farmed soils.

Co-exposure of microplastics and polychlorinated biphenyls strongly influenced the cycling processes of typical biogenic elements in anoxic soil

Researchers examined how co-exposure to polyethylene microplastics and polychlorinated biphenyls (PCBs) affects the cycling of carbon, nitrogen, iron, and sulfur in oxygen-depleted soil over 255 days. The presence of microplastics enhanced some processes like methane production and iron reduction while inhibiting nitrate reduction and PCB degradation. The study found that microplastics significantly altered the functional microbial communities responsible for these biogeochemical cycles, suggesting that combined plastic and chemical pollution creates more severe effects than either pollutant alone.
