Rapid economic development has led to an annual increase in municipal solid waste (MSW) production. According to the US Environmental Protection Agency (US EPA), MSW generation has increased by a factor of 2.6 since 1960 [1]. The US EPA endorsed the concept of integrated waste management that could be tailored to fit particular community’s needs. Sustainable and successful treatment of MSW shou...

Estimation of the rate of landfill gas (LFG) generation is needed (1) to satisfy USEPA and state regulatory requirements associated with estimating non-methane organic carbon emissions; (2) to assess the impact of landfill-generated methane on global warming; (3) as part of the design of LFG and methane control systems; and (4) to provide information necessary to evaluate and design LFG-to-ener...

Characterization of material changes with depth (profiles) in many landfill sites can be problematic for some conventional geophysical methods. Localized anomalies within the landfill can complicate mapping of underlying layers, and layered-model techniques are inappropriate for imaging laterally discontinuous landfills. Recently-developed geophysical hardware and software tools provide the opp...

The landfill of Bellolampo is located in northern Sicily and serves the greater area of Palermo (Sicily). In the recent past, the landfill has been progressively renovated in order to align the waste disposal process with the state-of-the-art technology. During the past years, the site had been equipped with seven biogas engines, fuelled with the biogas produced at the oldest part of the landfi...

landfilling is an ultimate fate of any municipal solid waste management system, and it is a no alternative choice for disposal of municipal solid waste. the major environmental concerns associated with landfilling of wastes are related to the leachate generation and eventual discharge of leachate into the environment. leachate quality is formed due to aerobic and anaerobic processes taking plac...

nonstop growth of urban population and concentration of industrial and agricultural activities in many parts of the world and iran have given rise to increased demand for water for different uses .furthermore, as one important factor of lack of exchange between human and environment resulting in wide exploitation from agricultural lands, mine extraction, and application of various industrial to...

Abstract Background and purpose: This paper presents a case study in simulation of process governing leachate occurrence and subsequent transport, and investigates its migration away from the landfill to control environmental adverse effects on a deep aquifer. Materials and Methods: The landfill examined in this study was an area of 240 ha and received 500 ton/day of solid waste generated fro...

Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue. Today municipal solid waste management (MSWM) is one of the most challenging issues in urban cities, which are facing a serious pollution problem due to the generation of huge quantities of solid waste. This results in development of environmentally sustainable...

Background and Objective: The purpose of this study was to use the HELP model to estimate the leachate generation rate and its pattern in a landfill located in the semi-arid region of Iran. Materials and Methods: The input data for the model were collected through fieldwork. To evaluate the accuracy of outputs, the actual amount of leachate production has been measured on-site for 10 months. ...
