Landfill Leachate Dilute and Disperse Philosophy and the Leachate Attenuation Zone
Landfill Leachate Dilute and Disperse Philosophy Landfills in the UK, built before the mid 1980’s were typically designed on a principle of dilute and disperse (EA, 2001/ Brown Book). The location of such sites was chosen so that the attenuation capacity of the underlying strata was sufficient to remediate the impact of the waste mass. […]
Anaerobic Digestion of Landfill Leachate for Energy Generation: Pipe-Dream or an Opportunity?
Anaerobic digestion is becoming increasingly popular in this age of high energy prices, and many more people are realising that whereas aerobic treatment systems consume large amounts of expensive energy, anaerobic digestion is a process which does the opposite. In fact it produces a net energy output. It is not surprising therefore, that many […]

Leachate Quality from Landfilled MBT Waste
In recent years there has been a trend toward MSW leachates from Sanitary Landfills throughout the world becoming more similar, however, as Mechanical Biological Treatment (MBT) is increasingly implemented and more Mechnanically Sorted Organic Residue (MSOR) [also known as “residual waste”] is produced in the supply area for a landfill, so the leachate quality of the landfill will change.
How you can Select the Best Pipework Material for Leachate Collection Systems in Three Simple Steps
This article is to make it easy to have success in selecting the best pipework material for leachate collection systems.
Pumps and Impellers for Leachate Extraction and Leachate Pumping
Popular pump types used for leachate extraction and pumping systems is the submersible centrifugal (vortex) type pump, and in particular in the UK the FLYGHT pumps model range.
The Use of Willow Coppicing for Leachate Treatment
WRc, has reported on Willow Coppicing for Leachate Treatment field trials in Britain inquiring into the utilisation of short rotation coppice (SRC) willow to treat leachate. The method is in use at several UK landfills where it is reported to be a low cost sustainable method of leachate treatment.
Avoiding Over Reliance on the Hydrologic Evaluation of Landfill Performance (HELP) Computer Program
“The person who walks with his/her eyes on the stars, is susceptible to the puddles in the road.” We all would like to follow our stars, but at times we need to do some “puddle watching” too! Sometimes we need to know what not to do, what things and actions to avoid, and why…
What is the Drainable Porosity of a Landfill?
When designing any leachate management system, the assessment of the most economically viable method for leachate treatment and disposal is heavily dependent upon the flow rate and duration of flow. A high capital cost option, such as on-site leachate treatment, will be worthwhile, but only if the total volume the plant treats daily is sustained […]
How Contaminants Leach Out of Landfill Waste and Into Leachate
A major problem arising from landfills is the discharge of leachate which is formed by water passing through the tip and thus becoming contaminated with various organic and inorganic pollutants. The subsequent movement of the leachate into the surrounding soil, ground water or surface water could lead to severe pollution problems. The mechanisms by which […]
