Press release issued on July 30, 2025
Residents living near Lean Quarry are being reminded to keep their windows and doors closed due to an ongoing fire at the waste facility in Horningtops, near Liskeard.
Cornwall Fire and Rescue Service responded to the incident in the early hours of Tuesday, July 22, sending multiple crews to tackle a fire involving a large amount of general waste.
The building was later deemed unsafe by a structural engineer and firefighters adopted a controlled burn strategy, meaning the fire is being monitored but crews cannot enter the building.
Biffa, which owns the site, is working to appoint a contractor to demolish the structure which will allow access to the fire.
