SESSION G10 / 12 October 2023 / 11:00 - 12:30
Workshop: Potential of candidate materials for methane oxidation systems
Chair / Presidente: Julia Gebert (NL), Marion Huber-Humer (AT)
During the past years more and more full-scale methane oxidation systems have been implemented on landfills to reduce methane emissions, benchmarking the transition from research and pilot scale to full field application. Successful system design involves the selection of suitable materials (e.g. mineral soils, compost) of a high CH4 oxidation potential. Also, it can be of interest to assess the potential of materials already in place in operational CH4 oxidation systems. Research into microbial CH4 oxidation has seen the application of many different field and laboratory methods to quantify a soil’s CH4 oxidation potential. They vary from small scale batch to meso-scale column tests to gas push pull tests in the field. Boundary conditions vary, for example with regard to feed gas concentrations, moisture content, temperature, compaction state of the material, duration of experiment etc., as does the interpretation of the data. To date, a standardized approach is still missing, which makes comparison difficult. The main purpose of the proposed workshop is therefore to discuss methods for the assessment of the CH4 oxidation potential of materials intended for use in CH4 oxidation systems or already in place. As main outcome it is intended to provide an overview of currently applied methods, to identify their limitations and benefits, the variables impacting the result, and to define the possible needs for method harmonization.
