Gas emission into the atmosphere from controlled landfills: an example from Legoli landfill (Tuscany,Italy)

Background, aim and scope  

Landfill gas (LFG) tends to escape from the landfill surface even when LFG collecting systems are installed. Since LFG leaks are generally a noticeable percentage of the total production of LFG, the optimisation of the collection system is a fundamental step for both energy recovery and environmental impact mitigation. In this work, we suggest to take into account the results of direct measurements of gas fluxes at the air–cover interface to achieve this goal.
