Environmental assessment and sustainable management options of leachate and landfill gas treatment in Estonian municipal waste landfills

This research paper uses the WAMPS life-cycle assessment model to compare leachate and landfill gas (LFG) treatment technologies in Estonian municipal landfills. It finds that reverse osmosis outperforms aerobic-activated sludge for leachate treatment and argues that improving LFG collection for energy recovery is more beneficial than flaring, as energy recovery can offset more environmental impact than the direct greenhouse gas emissions produced.

• Reverse osmosis is identified as having superior environmental performance for leachate treatment when compared to aerobic-activated sludge treatment.
• Current landfill gas (LFG) collection efficiency in the studied sites is relatively low. To enhance environmental performance, the study recommends improving gas collection rates and prioritizing energy recovery over flaring, as the avoided impacts from energy recovery can exceed the direct impacts of greenhouse gas emissions from the landfills.
