Abstract

Exploitation of the natural methane oxidation process in biotic systems in landfills through improved design offers an inexpensive way of reducing methane emissions. Maximization of this oxidation efficiency can promise a control over the harmful methane gas emissions from landfills. Research reveals the existence of high oxidation capacities in several waste materials such as diverse composts, dewatered sludge, or yard waste. In this study, the capabilities of an anaerobically digested, mechanically biologically treated (MBT) waste are tested for its potential use as a biotic system. Column studies were designed for laboratory testing whereas maximization of the oxidation capacity was investigated through numerical modeling. Experimental results indicate a high oxidation efficiency of 81 for MBT waste, confirming its applicability as a biotic system. Parametric study on the geotechnical properties optimizes the bulk density to 730-1,116 kg/m3 for achieving maximum oxidation efficiency. © 2020 American Society of Civil Engineers.
