Researchers use hemp, rock dust and biochar to scrub forever chemicals from farm soils
A Yale study found that using a combination of hemp plants, rock dust, and biochar can effectively remove PFAS from contaminated farmland soil. The method is projected to reduce chemical levels below safety thresholds within a decade at a much lower cost than traditional cleanup methods. The process also captures carbon dioxide, offering an additional environmental benefit. This approach provides a scalable and affordable solution to address the growing problem of PFAS contamination in agricultural areas.
Researchers tested using hemp, rock dust, and biochar to remove forever chemicals like PFAS from contaminated farmland soil.
This method could clean polluted soil more affordably and quickly than traditional methods, while also reducing carbon emissions.
It shows a practical, nature-based solution to a growing environmental problem, offering hope for restoring farmland and protecting public health.
