Scientists devise a breakthrough method to remove 'forever chemicals' (PFAS) that contaminate agricultural soil

A Yale research team has proposed a low-cost way to remove PFAS from farmland by combining rocks, plants, and biochar.

The method uses alkaline rock spread on soil, grows PFAS-absorbing hemp, then converts the harvested biomass into biochar to help capture contamination.

The approach could make PFAS cleanup far cheaper than current methods, with implications for food safety and environmental protection.

It may also deliver added carbon-reduction benefits through biochar production and soil treatment.
