Life Cycle Assessment and Life Cycle Costing Analysis for Removing Per- and Polyfluoroalkyl Substances from Landfill Leachate with Foam Fractionation Technology.

ABSTRACT: Understanding the environmental impacts and economic costs of treatment technologies is essential for developing sustainable strategies for managing per- and polyfluoroalkyl substances (PFASs). This study focuses on the treatment of PFAS-contaminated landfill leachate using foam fractionation (FF) technology. A parametrized life cycle assessment and life cycle costing analysis were conducted to evaluate the performance of one-stage and three-stage FF systems. Full-scale operational data and EPA design models were used to assess environmental and economic impacts based on a functional unit of treating 1000 m³ of PFAS-contaminated landfill leachate. The global warming potential was estimated at 818 kg CO₂ eq for the one-stage system with 20% foam fraction, 357 kg CO
