The carpet recycling group presented innovative strategies to remove PFAS from carpet face fiber fluff during recycling. The team provided strategies with a range of timescales to implementation. The first strategy involved using base hydrolysis and granular activated carbon (GAC) adsorption to remove but not destroy PFAS. The second strategy built on the first, but proposed using reverse osmosis and plasma treatment to destroy the PFAS. The third strategy proposed the use of esterase (specifically pig liver esterase) as an alternative to using sodium hydroxide in the other proposed strategies. Finally, the fourth strategy focused on the potential for laccase to mediate PFAS removal.
