Granville landfill site latest update: Monday 27 January 2025
Since the last email update, work to address odour issues at Redhill landfill site has continued, with operators Potters (Midlands) Ltd working through an action plan agreed with the Environment Agency, to improve gas and odour control.
Permanent capping of waste cells that were full from 2023 and early part of 2024 began in June 2024 and sealed over 30,000m2 which has now been completed; a final protective layer of soil is to be added and can be seen in the image below.

In parallel, waste that has continued to be tipped during 2024 has filled additional cells. In line with standard practice, these cells were due to be capped but unfortunately this was delayed before Christmas due to weather conditions. This is now progressing well and should be completed by the end of January 2025.
Once complete, extra gas wells will be installed to further reduce odour. Whilst this work takes place there may be a temporary increased risk of odour due to the potential disturbance of waste when installing the gas collection wells.
As part of the action plan, waste disposal operations have now moved to operate in a smaller working area (to reduce the area of exposed tipped waste). This will follow the new procedures introduced elsewhere on the site in 2024 to maximise gas collection, minimise odour and provide greater protection for the community
The Environment Agency will continue to monitor odours, track progress against the agreed action plan and review the operator’s management plan to ensure work continues in accordance with its permit.

We have also updated our webpage with the latest hydrogen sulphide (HS2) monitoring report, based on sampling carried out between 4 July 2024 and 7 October 2024.
The results show an ongoing improvement over the testing period and at all times HS2 levels have been significantly lower than guidelines used when assessing any long-term health impacts.
