Landfilling Ash∕Sludge Mixtures

The geotechnical properties of a mixture of municipal solid waste incinerator bottom ash and municipal wastewater treatment plant sludge was investigated for a proposed ash∕sludge secure landfill. The components as well as mixtures ranging from 10:1 to 5:1 (ash:sludge, by volume) were evaluated, where appropriate, for a number of geotechnical index and mechanical properties including particle size, water content, specific gravity, density-moisture relationships, shear strength, and compressibility. The results from a compactibility study and stability analysis of the proposed landfill were used to help approve a landfill codisposal concept; a full-scale facility was constructed and is currently operating successfully.     

Air Permeability of Waste in a Municipal Solid Waste Landfill

The permeability of compacted municipal solid waste in a landfill with respect to air (or gas) flow was estimated using a short-term air injection test. Air was added to 134 vertical wells installed at three different depths at flow rates in the range of 0.14?–1.4?m3?min?1 and the corresponding steady state pressures were recorded. The permeability of the waste with respect to airflow (described here as the air permeability) was estimated for different anisotropy ratios (kr/kz = 1, 10, and 100) using a steady state, two-dimensional, axisymmetric analytical fluid flow model in conjunction with the measured flow and pressure data. The air permeability of landfilled municipal solid waste modeled as an isotropic medium was found to range from 1.6×10?13 to 3.2×10?11?m2. The estimated air permeability results were on the low end of values previously applied to model landfill gas flow. Estimated air permeability decreased significantly with increasing waste depth. The lower permeability encountered in the deeper layers was primarily attributed to the lower porosity of the waste caused by higher overburden pressures and higher moisture content of waste in deeper layers of the landfill than in shallow layers. The results suggest that multiple wells screened at different depths provide greater control of air distribution within the landfill. Leachate recirculation was documented to impact the ability to add air. In addition to limitations posed by standing water in many of the deeper wells, waste exposed to leachate recirculation was found to be significantly less permeable to air when compared to original conditions.

Municipal Solid Waste Slope Failure. I: Waste and Foundation Soil Properties

This paper describes a slope failure in a municipal solid waste landfill, with lateral and vertical displacements of up to 275 and 61 m, respectively. The wasteslide involved approximately 1.2 million m3 of waste, making it the largest landfill slope failure to occur in the United States. Failure developed through the weak native soil underlying the waste. The analyses and related studies conducted to determine the cause of the failure are the subject of this and a companion paper by Stark et al. (2000). To facilitate the analyses, this paper investigates shear strength of municipal solid waste using field and laboratory test results and back-analysis of failed waste slopes. It also presents details of a geological study and laboratory testing program undertaken to quantify the mobilized shear strength of the weak native soil.     

Life-Cycle Assessment of Waste Management Greenhouse Gas Emissions Using Municipal Waste Combustor Data

This paper compares life-cycle greenhouse gas (GHG) emissions from two municipal solid waste (MSW) management options, municipal waste combustion, and landfilling, using a U.S. EPA life-cycle assessment (LCA) model, the MSW Decision Support Tool. Unlike previously reported LCAs, key combustion model inputs—total MSW carbon content and its biogenic/fossil split—are determined not from MSW composition studies, but from measurements taken at operating municipal waste combustors (MWCs). MWC measurement data show U.S. MSW carbon content averages of 30% with a biogenic/fossil split of 66%/34%. The LCA also considers a range of landfilling scenarios which account not only for alternative landfill gas (LFG) management techniques, but also for the variability of landfill methane generation and capture. The LCA found that for the range of inputs and scenarios considered, municipal waste combustion outperforms landfilling in terms of GHG emissions, regardless of the LFG management technique.     

Gas-Phase Mass Transfer Processes in Landfill Microbiology

This report assesses gas-phase mass transfer processes in landfills with respect to their influence on waste biodegradation. Gas-phase transport must dominate in many regions of the waste because aqueous-phase transport is restricted, the environment is largely unsaturated, and substantial quantities of gas are produced. Analysis of landfill gas and landfill gas condensate at four municipal solid waste landfills in the eastern United States demonstrated that both volatile fatty acids and microorganisms are transported in the gas phase. The heterogeneity, mass transfer limitations, and significant thermal gradients in waste environments imply that gas-phase processes can play crucial roles in waste decomposition, for example by regulating local pH and distributing trace nutrients. A conceptual framework describing these processes is presented. Implications for waste management, landfill design, energy production, air emissions, and anaerobic microbiology are discussed.
