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 […]

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 the significant possible environmental problem to be conquered. Although research and experience continue to […]
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 […]
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 […]
When designing any leachate management system the assessment of the most economic 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 […]
Leachate pumps and pumping technologies currently in use in landfills in the UK, and worldwide, are listed and explained.
Leachate extraction embraces landfill site wells and boreholes, pumping systems, plus pipelines, leachate monitoring and control systems.
Leachate recirculation in the form of pumping leachate from the base of a cell back up into the top of the waste has been practised in the past, and continues to be used, at the majority of landfills.
Leachate landfills – general information about leachate, and how it is present in landfilled waste, affects landfills, and is collected.
