a System boundary of phytoremediation coupled with biomass pyrolysis for LCA. b Residual PFAS levels in the biochar (BC) produced from pyrolysis of O. rosea biomass at different temperatures, with the removal efficiency for ∑82PFAS provided above the bars. c Comparison of LCA results among phytoremediation plus pyrolysis (PP), soil washing (SW), and magnetic activated carbon plus hydrothermal alkaline (MAC + HALT). The environmental impact categories compared include GWP global warming potential, FFP fossil resource scarcity, HOFP Ozone formation, Human health, TAP Terrestrial acidification, FETP Freshwater ecotoxicity, HTPc Human carcinogenic toxicity, with the results of the other 12 categories provided in Supplementary Fig. 25. d Comparison of GWP and FFP results of phytoremediation plus pyrolysis for different PFAS.
