Abstract

We assessed the suitability of various biogenic materials for development of a gradient packed bed bio-filter to mitigate the methane (CH₄) emission from landfills. Five different biogenic materials (windrow compost-WC; vermicompost-VC; landfill top cover-LTC; landfill bottom soil-LBS; and river soil sediment-SS) were screened. Among these materials, the VC showed a better CH₄ oxidation potential (MOP) of 12.6 μg CH₄ g_dw⁻¹ h⁻¹. Subsequently, the VC was used as a packing material along with wood chips in proto-type bio-filters. Wood chips were mixed at 5–15% to form three distinct gradients in a test bio-filter. Under the three different CH₄ loading rates of 33, 44 and 55 gCH₄ m⁻³ h⁻¹, the achieved MOPs were 31, 41, and 47gCH₄ m⁻³ h⁻¹, respectively. The gradient packed bed bio-filter is effective for landfill CH₄ mitigation than the conventional bio-filter as the latter shows gas channeling effects with poor MOPs.
