As well as variation due to different methods of compaction, waste in a landfill can be substantially compressed by the weight of overlying layers, which may reach several tens of metres deep.…”

The effect of applied compression on the nature of liquid flow and hence the movement of contaminants within Municipal Solid Waste was examined by means of thirteen tracer tests conducted on five separate waste samples. The conservative nature of bromide, lithium and deuterium tracers was evaluated and linked to the presence of degradation in the sample. Lithium and deuterium tracers were non-conservative in the presence of degradation, whereas the bromide remained effectively conservative under all conditions. Solute diffusion times into and out of less mobile blocks of waste were compared for each test under the assumption of dominantly dual-porosity flow. Despite the fact that hydraulic conductivity changed strongly with applied stress, the block diffusion times were found to be much less sensitive to compression. A simple conceptual model, whereby flow is dominated by sub-parallel low permeability obstructions which define predominantly horizontally aligned less mobile zones, is able to explain this result. Compression tends to narrow the gap between the obstructions, but not significantly alter the horizontal length scale. Irrespective of knowledge of the true flow pattern, these results show that simple models of solute flushing from landfill which do not include depth dependent changes in solute transport parameters are justified.

“…Unlike soil solids, which are generally considered incompressible, many of the solid components comprising MSW are compressible and may therefore undergo an increase in density and specific gravity as load is applied (Hudson et al 2004. Specific gravity is defined as the ratio of unit weight of solids Sowers (1973) proposed that, to mitigate excessive landfill settlements, it might be desirable to control environmental factors to retard decomposition (known as dry tomb landfilling), thereby reducing decomposition related settlement.…”

shear strength testing over moisture contents ranging from 11% to 110%. Baseline compaction curves were developed for different compactive efforts. Similar to soils, the MMSW had bell shaped compaction curves that peaked at a maximum dry unit weight and associated optimum moisture content. The compaction curve generated at modified compactive effort had a maximum dry unit weight of 5.1 kN/m 3 and optimum moisture content of 66%. Four times modified compactive effort testing resulted in a maximum

This study investigates the sustainability-related impacts of the Framing Hope program, an innovative private and nonprofit sector partnership between the nonprofit Good360 and The Home Depot. Specifically, this paper estimates the energy savings, landfill space not filled, and the energy-and landfill-related cost savings associated with the Good360 product philanthropy program with The Home Depot, illustrating that benefits accrue to both company and communities by linkages between environmental, socioeconomic, and energy dimensions. Findings suggest that by redirecting products from the waste stream into usable community resources, considerable landfill space, costs, and energy savings were realized. Product donations can serve as an important platform for sustainable community development and capacity building. This research adds to the growing body of knowledge on environmental performance, corporate giving, and cross-sector partnerships in sustainable and social entrepreneurship.
