Project Summary: This comprehensive study has been conducted to investigate thermal regime of municipal solid waste landfills. Extensive field data have been obtained at four landfills located in North America, Michigan, New Mexico, Alaska, and British Columbia since 1999. Thermal response of the landfills is determined as a function of operational and climatic conditions. Spatial and temporal variations of temperatures were determined in liner systems, wastes, and covers as well as surrounding subgrade using over 1000 sensors at the combined sites. Laboratory and field tests are conducted to determine thermal properties of wastes and liner materials. Heat generation and development of low or high temperature trends in the wastes are determined under variable waste decomposition conditions. Heat generation and transfer in wastes and liners are determined using numerical analysis. Models are developed to predict heat content, generation, and transfer in landfills and impacts of temperatures on the surrounding environment with broad applicability to waste management industry. Design tools are developed for controlling and manipulating temperatures in wastes, covers, and liners. Temperature control in landfills can be used to: maintain optimum temperature ranges for maximum gas generation, maintain low waste temperatures to protect underlying liners, adjust liner and cover temperatures to protect against desiccation and freeze/thaw, maintain optimum cover temperatures for maximum methane oxidation. Overall, the temperature and gas data obtained and the heat transfer analyses conducted in this seminal investigation represent the most complete investigation of its kind conducted to date.
