Assessment of issues relating to leachate recirculation
Assessment of issues relating to leachate recirculation
SUMMARY: The Environment Agency has commissioned a brief technical review of leachate recirculation, including a survey of current practice and experiences in the UK. A framework identifying technical, environmental and operational issues has been prepared, and a survey conducted of six major UK landfill companies, covering ~90 landfills. Recirculation is widely practised, utilizing a wide range of infrastructure designs. There is a high level of interest among UK operators, with seasonal flow balancing and stimulation of gas being the most common drivers. Quantities are typically in the range 5,000 to 20,000 m3/a. The main environmental issues appear to be odour from some systems, filling up of gas wells, and surface outbreaks. The main operational issue is clogging. More monitoring is needed to assess performance.
