This paper reviews and extends understanding of evaporation/distillation as treatment for landfill leachate. Evaporation may produce condensate that is high quality and easier to dispose of than effluent from conventional leachate‐treatment processes with the volume of the concentrated residuals being a small fraction of the original leachate volume. Laboratory‐scale, one‐ and two‐step distillation experiments with pH adjustment were performed with ammonium acetate test solution and three leachate samples from older landfills. A single‐step, acidic distillation of the strongest leachate samples removed more than 95% of ionic impurities, except for volatile organic acids, which were removed at 85%. Two‐step acid‐base evaporation, or ammonia stripping coupled with evaporation, may effectively remove ammonia and volatile organic acids if present together in relatively high concentrations. A Monte Carlo analysis of the feasibility for energy‐self‐sufficient leachate evaporation via landfill methane combustion...
