Aerobic Landfill Bioreactors
Previous work on landfills has focused mostly on anaerobic pathways of biodegradation. Modeling of landfills has been sparse due to difficulty in dealing with the heterogeneous nature of the refuse as a media for flow and transport and as a nutrient source, making predictive modeling and real-time control of processes less than optimal There has also been an increasing focus on landfills gases as a major contributor to green house gas and increasing costs of usable land, containment costs, and prolonged liability for landfill sites.
Our approach is to use mesoscale models of landfill refuse to determine aerobic parameters that are critical to optimizing biodegradation and stabilization of refuse and to use LBNL developed codes TOUGH2 and ITOUGH2 to develop a numerical simulation model of aerobic bioremediation of landfills. We are also pursuing field demonstrations to help verify and fine tune simulation model and critical parameters discovered in mesoscale studies at California municipal landfills and western DOE sites.
