As leachate migrates away from a landfill, it may cause serious pollution to the groundwater aquifer as well as adjacent surface waters. There is growing concern about surface and groundwater pollution from leachate. Better understanding and prediction of leachate generation, containment, and treatment are by: Controlling gas and leachate production is a primary objective of sound landfill management. Gases, composed mainly of carbon dioxide and methane, are formed during the decomposition of solid wastes. Leachate forms as water passes through the refuse, dissolving out chemicals. Find landfill gas (waste and recycling) books and publications, the world’s largest environmental industry marketplace and information resource. Since landfills often have a significant supply of naturally occurring gas; there is great potential to use this gas as a free energy source to evaporate the wastewater. ENCON offers thermal evaporators that can efficiently burn the off spec landfill gas at a rate that keeps up with the generation of landfill leachate wastewater.

Leachate generation at MSW landfill. Adapted from: Qian, X., R. M. Koerner, and D. H. Gray. Geotechnical Aspects of Landfill Design . We are often asked “What is Landfill Gas”.On this page we provide an explanation the meaning of “landfill gas”, and a lot more. We aim to give readers a grounding in the subject of landfill gas, and its uses.. Landfill gas is a complex mix of different gases created by the action of microorganisms within a landfill. Landfill aeration technology is gaining increasing interest worldwide for the reduction of gas and leachate emissions from old landfills, achieving environmentally sustainable conditions. In-situ aeration should be controlled in order to maintain water content, temperature, oxygen content etc. at optimum conditions. Strategies for dealing with leachate, gas, and storm water How to estimate the costs of construction, operation, final closure, and long-term monitoring of landfills No other single source offers as much time- and money-saving information on landfills as Design, Construction, and Monitoring of Landfills by Amalendu by:
Once MSW has been deposited on a dump or in a sanitary landfill, it continues to decompose. The products of decomposition are mainly gas (known as landfill gas or LFG) and leachate. In the period shortly after the waste has been landfilled, the pore space is filled mainly with nitrogen and oxygen having much the same proportions as the ambient air.

The generation of leachate and gas from landfills is a well documented phenomenon which impacts landfill design and operation. Leachate and gas production are both influenced by the contents of the landfill, the local climate, and the manner in which the facility is operated. Gas composition and volume will be discussed in this chapter as will Cited by:
