‘The future of the landfill industry depends on managing the legacy issues of the sites , more than 50% of the costs relate to disposal of the leachate. Reducing these and recovering resources from the leachate is critical for the circular economy – we are excited to be working with LAT Water on achieving these objectives.’

Treatment of raw leachate
Broadpath Landfill, UK
In January 2021 LAT Water completed the installation of a wastewater treatment plant at Broadpath landfill in Devon, UK. The plant is treating raw leachate.
LAT Water installed one unit to treat 10m3/day.
The system was powered using waste heat from the exhaust gas of a 1MW GE Jenbacher bio gas generator.
The raw leachate had TDS over 5,500 and high levels of ammonia, COD & TOC. LAT Water achieved a minimum water recovery of 70%, reaching up to 90%.
The project delivered an overall operating cost reduction of 48%, and a 70% reduction in energy use.
The pilot has been partly funded by the department of Business Energy & Industrial Strategy (BEIS), as part of their Industrial Energy Efficiency Accelerator (IEEA). The programme is managed by The Carbon Trust with supports from Jacobs and it provides funding for energy efficiency process technologies, alongside incubation and commercialisation support.Industries
