Full-Scale Laboratory Study into Clogging of Pipes Permeated with Landfill Leachate
(American Society of Civil Engineers, 2009)Full-scale high-density polyethylene pipes of external diameter 0.05 and 0.1 m, and internal diameter 0.04 and 0.08 m, were permeated with leachate to characterize the changes in select leachate constituents within the ... -
Effect of Waste Composition and Load Application on the Biodegradation of Municipal Solid Waste in Bioreactor Landfills
(American Society of Civil Engineers, 2009)Intensive research has focused on the biodegradation of the typical municipal solid waste in bioreactor landfills, but relatively little attention has been given to the biodegradability of individual refuse components. The ... -
Evaluation of an Alternative Method of Leachate Collection System Design
(American Society of Civil Engineers, 2009)The current practice of leachate collection and removal system (LCRS) design for sanitary landfills has limitations because of the uncertainties associated with a key design parameter, leachate production rate. The traditional ... -
Potential Lateral Migration of Leachate in Flushing Bioreactor Landfills during Aggressive Leachate Recirculation
(American Society of Civil Engineers, 2009)Although there are advantages of bioreactor landfills over traditional sanitary landfills, the operation of bioreactor landfills is not without problems. A number of operational problems may arise when leachate is either ... -
Optimization Tool to Maximize Use of Resources for Environmental Improvements to Waste Disposal Sites
(American Society of Civil Engineers, 2009)In countries where resources are limited, especially in developing countries, it is important to use all available resources effectively and efficiently for the mitigation of environmental impacts caused by waste disposal ... -
Optimization of Municipal Solid Waste Collection System: Case Study
(American Society of Civil Engineers, 2009)Curbside collection of municipal solid waste (MSW) constitutes a substantial portion of waste management cost. The utilization of operations research tools for the reduction of MSW collection costs in the Township of ... -
Selecting Appropriate Analytical Methods to Characterize Asbestos in Various Media
(American Society of Civil Engineers, 2009)Methods for the measurement and analysis of asbestos and other fibers in air, water, dust, and bulk materials vary by type of scenario and according to applicable laws and rules. Two surveys and a focus group were used to ... -
