Summary
Adding fly ash to municipal solid waste (MSW) landfills can reduce landfill compression. This technique enhances landfill stability for construction, improving initial and long-term performance.
Area of Science:
- Geotechnical Engineering
- Environmental Engineering
- Waste Management
Background:
- Municipal solid waste (MSW) landfills pose compression challenges when used as construction foundations.
- Geotechnical engineers require reinforcement strategies for MSW landfill end-use applications.
Purpose of the Study:
- To investigate the stabilization of MSW landfills using codisposal with fly ash.
- To assess the impact of fly ash on landfill compression characteristics.
Main Methods:
- Large compression set tests were conducted.
- Experimental cells were utilized to simulate codisposal conditions.
Main Results:
- Increased fly ash proportion significantly reduced initial compression.
- Higher fly ash content led to decreased long-term compression.
Conclusions:
- Codisposal of MSW and fly ash is a viable technique for landfill stabilization.
- Optimizing fly ash content can mitigate compression issues in landfills intended for construction.
