Supported by the RMC Environment Fund through the Landfill Tax Credit Scheme, this research has designed sustainable landfill leachate treatment systems based on short rotation willow coppice (SRC).
Two large scale trials were established by WRc on landfills belonging to the RMC Aggregates (Greater London) Ltd in Southeast. The trials operated for four years and were supported by glasshouse and laboratory investigations of specific aspects of the treatment system.
Leachate irrigation to the field trials was controlled using direct feedback from environmental monitoring systems including TDR soil moisture measurement. A number of different irrigation regimes were investigated.
- A system for the long term management of landfill leachate at the 2 landfill sites.
- Operational and management guidelines for the development of SRC based leachate management systems in other locations.
