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

The study uses the WAMPS life-cycle assessment (LCA) model to evaluate leachate and landfill gas (LFG) treatment options in Estonia, finding that reverse osmosis outperforms aerobic-activated sludge for leachate treatment and that LFG energy recovery is preferable to flaring due to significant avoided impacts.

• Reverse osmosis is identified as having superior environmental performance for leachate treatment when compared to aerobic-activated sludge treatment, a result supported by both LCA and direct measurements in the studied landfills.
• Current landfill gas (LFG) collection efficiency in the studied sites is relatively low; improving the collection rate and prioritizing energy recovery over flaring is essential, as the avoided impacts of energy recovery can exceed the direct greenhouse gas emissions impacts.
• The environmental assessment focused specifically on eutrophicating impacts and global warming, meaning the results do not represent the total environmental impacts of the entire landfill system.
