Pumice has been shown in laboratory biofilter experiments to improve the oxidation of methane (Pratt et al. 2012, Pratt, Tate, & Deslippe 2012). Pumice biocovers were tested on two Icelandic landfills, Kirkjuferjuhjáleiga and Álfsnes. Seven biocover plots were dug and filled with a 50:50 blend of pumice and native soil. CH4 and CO2 were measured using the static chamber method before and after biocover placement. After one week, the CH4:CO2 ratio was reduced on four of the seven plots, weakly indicating that pumice biocovers may be an effective way to better oxidize landfill methane.
