a Picture of the kilogram-scale REM process. b Simulated distribution of current density on the soil surface with external voltage input. c 3D mapping of PFOA removal efficiency. The mapping was sampled from 52 positions of 4 plane depths with an interval of 2 cm and 13 points in each plane. d Materials flow analysis of REM. The dash rectangle denotes the system boundary. e Comparison of cumulative energy demand. f Comparison of cumulative GHG emission. g Comparison of operating cost. h Comprehensive comparison of different soil-remediation methods.
