MBT waste processing leachate a waste of money

Leachate Quality from Landfilled MBT Waste and Why MBT is an Unjustified Waste of Money

In a research project completed on behalf of the UK Environment Agency data was collected data and leachates were sampled from EU landfills that had received imports of MSOR (Mechanically Sorted Organic Refuse) and Mechanical Biological Treatment (MBT) wastes, several years ago. The results of the sampling exercise were analysed for, the presence of trace […]

leachate indicator parameters

The 3 Most Important Leachate Indicator Parameters

There are three very important leachate indicator parameters which are used as indicators to identify leachate contamination in any water sample analysed in a water quality laboratory. These three parameters can give an initial guide to anyone investigating what appears to be pollution occurring in the vicinity of a landfill, as to whether the source […]

A sanitary landfill

Sanitary Landfill Leachate Past and Future

INTRODUCTION Within the last many years there have actually been major advances in the variety, engineering, and control of landfill sites; however, it is still a fact that at many sites the generation of very polluting sanitary landfill leachates is still a significant possible environmental problem to be conquered. Although research and experience continue to […]

leachate recirculation in a landfill

Leachate Recirculation Practise and Views

To the site operator leachate recirculation would certainly appear like commonsense as some of the leachate recirculated will be taken in by the waste and not re-appear. The leachate will gain some treatment – especially a significant reduction in BOD and COD by anaerobic digestion within a methanogenic landfill. In addition, if leachate is being […]

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. […]

Willow coppicing leachate treatment - A possible product is a willow fox like this!

The Use of Willow Coppicing for Leachate Treatment

WRc, has reported on 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 meathod of leachate

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…

Landfills Leachate – 3 Things All Landfill Operators Will Wish to Avoid

Landfill Operators must watch out for any landfills leachate accumulating in their landfills. This is to avoid finding that large volumes of leachate have collected which may escape and threaten to the local water environment. The solution is given here.
