The reduction of landfill gas emissions is a central issue of the Directive 99/31/EC. Biofilters and biocovers have been identified as an alternative and cost-effective technologies to mitigate impacts due to CH4 and NMVOCs emissions. The Life Cycle Assessment demonstrates the environmental sustainability of biofiltration systems, with the aim of improving the environmental impact indicators such as Global Warming (-10.75% for Biofilter and -11.60% for Biocover) and Photochemical oxidation (-7.97% for Biofilter and -8.61%. for Biocover). This paper shows that these treatment technologies are effective for methane oxidation when the calorific value of the LFG is low, thus they maximize the amount of treated gas during the after-care phase.

Abstract
The reduction of landfill gas emissions is a central issue of the Directive 99/31/EC. Biofilters and biocovers have been identified as an alternative and cost-effective technologies to mitigate impacts due to CH4 and NMVOCs emissions. The Life Cycle Assessment demonstrates the environmental sustainability of biofiltration systems, with the aim of improving the environmental impact indicators such as Global Warming (-10.75% for Biofilter and -11.60% for Biocover) and Photochemical oxidation (-7.97% for Biofilter and -8.61%. for Biocover). This paper shows that these treatment technologies are effective for methane oxidation when the calorific value of the LFG is low, thus they maximize the amount of treated gas during the after-care phase.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
