Cochin International Airport Limited (CIAL) has strengthened runway safety by bringing in a modern rubber removal machine called CleanJet to its airside operations in Kochi.
• The machine tackles the buildup of tyre rubber that accumulates in the touchdown zone every time an aircraft lands, which can be as much as around 1.5 lbs per tyre — and this buildup can make the runway surface too smooth and reduce friction if not removed.
• Reduced runway friction is a safety concern, especially in wet weather, because it increases the required braking distance and effective runway length for aircraft, making landings and takeoffs riskier.
• CleanJet was manufactured by Anlon Technology Solutions and is now in service at CIAL to restore runway texture and maintain proper friction levels for safer aircraft operations.
• How CleanJet works:
– It uses high‑pressure water jets (around 2,500 bar) combined with specially angled rotating discs to break up and lift rubber deposits from the runway surface.
– The loosened rubber and water are suctioned into a waste‑water tank, ensuring no residue remains on the runway after cleaning.
• The design of the system helps remove deposits efficiently while minimising the need for long runway closures, allowing smoother and quicker maintenance cycles.
• CIAL officials stated that deploying this machine will improve routine maintenance practices, reduce safety risks from low‑friction runway surfaces, and boost operational reliability, particularly during Kerala’s heavy monsoon conditions.
• Engineers at the airport will monitor CleanJet’s performance and adjust runway maintenance schedules as needed to consistently uphold surface friction levels.
