Remediation of the Landfill underway
Great progress is being made on the remediation of the landfill, which comprises an area of 24,000 sq. metres and is a fundamental element of Roche's pledge to restore the site to a brownfield status, capable of attracting new investment. The excavation of waste from the landfill is being undertaken within large airtight enclosures to guarantee containment of dust, odour and emissions. Two enclosures are being used for the landfill excavation works.
There are a total of 9 individual cells in the landfill. The remediation involves the removal of all the waste that was placed in these cell.
The larger enclosure (100m long x 44m wide x 13m high) is being used to excavate waste from cells 3,1,8, 4,2 and 9 in that order. this enclosure is moved from cell to cell via a sliding rail and does not need to be dismantled.
The smaller enclosure (100m long x 28m wide x 13m high) is being used for cell 5,6,and 7. Excavation is complete in cells 3,1,8, and 5, and 7 is almost complete.
The scale of the larger enclosure can be gleaned from the above photo taken during a visit to the site by the Ambassadors of Switzerland and Austria to Ireland. This photo was taken post remediation, when cell 3 was being backfilled with clean soil. Photo by Eamon Ward Photography.
A Team Effort
Preparing the landfill for the excavation of waste involved multiple teams, led by Roche Project and the main contractor, Indaver.
We thank each member of every team for their hard work which enabled Roche to reach its milestone of being ready to start excavating waste in the landfill at the beginning of 2025.

Background to the Landfill
The site infrastructure originally included an on-site landfill which was initially licensed by the local authority and subsequently by the Environmental Protection Agency (EPA). The requirement for a landfill was linked to the fact that waste emanating from Roche’s on-site manufacturing activities could not be sent to municipal landfills, hence it was placed in the landfill.
In 2006, a higher focus on recycling resulted in the landfill being capped and closed. Non-recyclable waste was sent to off-site waste management facilities designed specifically for handling waste generated from the site
When Roche announced its the decision to cease operations in Clarecastle and to fully remediate the site to enable it to have a sustainable future, the removal and remediation of waste deposited in the on-site landfill was an intrinsic part of this decision.
