Development of novel porous carbon materials for reducing total PFAS emission including cost-benefit analysis and bioavailability of immobilized PFAS to terrestrial organisms.

PFAS are persistent pollutants widely used in industrial and commercial applications and are now ubiquitous in the environment. In Sweden, more than 2,000 PFAS-contaminated sites have been identified, including firefighting training areas, airports, industries, and landfills. This project aims to develop novel porous carbons from rice husks to reduce PFAS leakage by removing PFAS from wastewater and immobilizing them in contaminated soils. The effectiveness of the materials will be assessed through total PFAS measurements in water, soil, earthworms, and vegetables. A cost-benefit analysis will also be conducted. The project supports Swedish and EU PFAS regulations and contributes to national environmental objectives and the UN Sustainable Development Goals.
