“…As an exception, Koerner �2001� re ported high short-term waste temperatures �30°C over initial two years� followed by low long-term temperatures �10-20°C over 9.5 years�. For covers, Yeşiller et al �2008� reported that tempera tures typically followed seasonal trends with phase lag and am plitude decrement with depth. For bottom liner systems and bases of landfills, long-term temperatures between approximately 30 and over 50°C were observed.…”

Long-term spatial and temporal variations in temperatures have been investigated in covers, wastes, and liners at four municipal solid waste landfills located in different climatic regions: Alaska, British Columbia, Michigan, and New Mexico. Temperatures were measured in wastes with a broad range of ages from newly placed to old �up to 40 years�. The characteristic shape of waste temperature versus depth relationships consisted of a convex temperature profile with maximum temperatures observed at central loca tions within the middle third fraction of the depth of the waste mass. Lower temperatures were observed above and below this central zone, with seasonal fluctuations occurring near the surface and steady and elevated values �above mean annual earth temperature� near the base of the landfills. Heat gain and long-term temperatures were directly affected by placement temperatures. Sustained concave tem perature profiles were observed for winter waste placement. The highest heat gain and resulting high temperatures were observed in Michigan followed by British Columbia, New Mexico, and Alaska. The high heat gain in Michigan was attributed to coupled precipitation/moisture content and waste density. The time-averaged waste temperature ranges were 0. 9-33.0, 14.4-49.2, 14.8-55.6, and 20.5-33.6°C in Alaska, British Columbia, Michigan, and New Mexico, respectively. Temperature increases occurred rapidly �over multiple years� in British Columbia and then dissipated for tens of years. Longer periods of temperature increase were observed at the other sites. Temperatures, temperature increases, and heat gain were higher during anaerobic decomposition of wastes than aerobic decomposition. A parametric study indicated that use of insulating materials over covers decreased temperature variations compared to uninsulated conditions for prevention of frost penetration or desiccation and for optimum methane oxidation. Overall, thermal regime of landfills is controlled by climatic and operational conditions.

“…Temperature ranges within the top 1 m of cover soils and in the geosynthetics in final covers beneath 1 m of cover soil are generally similar to temperature ranges the air above a landfill, with some reduction in seasonal temperature amplitude. In areas with cold winters and mild summers, geosynthetic temperatures in final covers have been reported from a maximum of 22-25°C to a minimum of 2-4°C (Yesiller et al 2008). …”

“…The disposal of waste into landfill is the most commonly adopted method in many countries, despite being the least recommended waste management solution. Waste decomposition is always associated with the production of landfill gas (LFG) and leachate from the waste mass, and is accompanied by effects of heat generation as a result of the continuous aerobic and anaerobic processes (Yesiller et al, 2005(Yesiller et al, , 2008. Long-term heat generation in landfill is mainly caused by an LFG that primarily consists of methane and carbon dioxide due to the continuous biochemical process that primarily involves decomposition of organic waste components (Nastev et al, 2001;Yesiller et al, 2005).…”

Detection of waste dumping locations in landfill using multi-temporal Landsat thermal images

The disposal of solid waste in a conventional landfill is inevitably associated with potential adverse environmental impacts, resulting in the migration of landfill gas and offensive odors on the surrounding areas. In addition to the obnoxious fumes and hazardous leachate, heat generation is continuously observed within the landfill during the aerobic and anaerobic phases. Despite the negative impacts, such "heat generation" phenomenon can turn into valuable information to aid in detecting unauthorized landfill activities and tracing unrecorded dumping regions. The spatial distribution of waste buried under the ground can be approximated and revealed through measuring the ground surface heat flux. In this study, we demonstrate how to utilize thermal remote sensing techniques to measure the land surface temperature (LST), which can aid in outlining the waste dumping regions within a landfill. The Jeleeb Al-Shuyoukh landfill, located in Kuwait, was used to demonstrate the proposed method, where the record of the exact dumping location was missing during the Gulf war. Ten-year Landsat Thematic Mapper(TM)/Enhanced Thematic Mapper Plus (ETM+) images (1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994) were acquired and processed in order to compute the LST within the landfill. Through combining the multi-temporal LST contours and overlay analysis, the most probable dumping regions within the landfill were outlined. A probability map was created to indicate the possible location of waste dumping within the studied landfill. With reference to the 50 boreholes drilled by the Environmental Protection Authority of Kuwait, our results derived during the summer and winter seasons both yielded an overall accuracy of 72%.
