Coupled Analysis of Leachate Recirculation and Heat Transfer for a Landfill with Buried Waste Tyres

Effects of Bonded Tyres on Leachate Recirculation of Bioreactor Landfills

Results and Conclusion: In this study, a numerical two-permeability flow model was used to investigate the effects of tyres embedding on the outflow rate of leachate injection. Furthermore, it was coupled with momentum balance equations to determine the local factor of safety of slope stability. The established model was applied to a simplified bioreactor landfill. The simulation results demons...

Evaluation of a buried vertical well leachate recirculation system for municipal solid waste landfills.

Vertical liquids addition systems have been used at municipal landfills as a leachate management method and to enhance biostabilization of waste. Drawbacks of these systems include a limitation on pressurized injection and the occurrence of seepage. A novel vertical well system that employed buried wells constructed below a lift of compacted waste was operated for 153 days at a landfill in Flor...

Improvement of Waste Decomposition in Leachate Recirculation Simulated Landfill by High Water Addition

A considerable amount of research has been conducted to demonstrate the development of bioreactor landfills promoted by leachate recirculation [1-10]. The effectiveness of leachate recirculation has been well documented in lysimeter studies [1, 5, 11, 12], test cell studies [2, 13, 14-16] and full-scale studies [17-20]. However, the results from these investigations might not be applied appropr...

Geophysical Monitoring of Leachate Recirculation at Orchard Hills Landfill

Landfill wall revegetation combined with leachate recirculation: a convenient procedure for management of closed landfills.

There is a need for a reliable sustainable option to effectively manage the landfill leachate generation. This study presents a simple procedure for the revegetation of the walls of closed landfills, employing the leachate as a fertirrigant. The native plants Lepidium sativum, Lactuca sativa, and Atriplex halimus, which suit the local climate, were chosen for this study in Southern Italy. The m...
