Biogas quantification and characterization

Even if it has got the best cover and gas caption system, every landfill generates uncontrolled emissions; therefore the current regulation (Legislative Decree No36/2003) orders the quantification and characterization of diffused and conveyed biogas emissions in dumps. Monitoring is necessary to characterize these emissions and find every possible biogas leaks outside the dump before they become a risk. A correct and precise emissions characterization is crucial to optimize the development of biogas caption nets, guaranteeing the best extractive efficiency possible.

Our services

  • Methane diffused emissions monitoring from dumps surfaces, according to LFTGN 07 protocol (Landfill directive: guidance on monitoring landfill gas surface emissions).Monitoraggio biogas discaricheThe biogas emissions esteem from a dump is realized through the English regulation approach, which can be reassumed in these stages:
    • Planimetry and morphological dump characteristics preliminary study
    • Site inspection and zoning
    • Methane emissions monitoring using FID-FluxBox technique
    • Data elaboration
    • Reporting
  • Forecast models for biogas production (LandGEM)
  • OGI Inspections (Optical Gas Imaging).Monitoraggio biogas OGI
  • Biogas caption greeds and nets consulting.

Landfills biogas production

We can consider landfills as anaerobic digesters that produce biogas from waste decomposition.

Almost the whole produced gas can be extracted using an optimized caption system. The biogas production can last for over 20 years after the dump closing: the chance to regain this biogas can surely represent a significant economic advantage.

The graphic below shows biogas production over the years: here you can spot the production peak during the first stages and the biogas progressive decrease with the passing of time.
