Changi Airport is turning waste into power, specifically, used cooking oil from its eateries is now fuelling runway sweepers and other heavy vehicles. The renewable diesel, refined by Neste Singapore, mimics fossil diesel and works in existing engines without modification.
The trial began in May with a 50 per cent blend and moved to 100 per cent in August, aiming to slash emissions by up to 90 per cent compared to regular diesel. Seven vehicles are currently involved, with performance showing no drop in efficiency or reliability.
While renewable diesel costs nearly twice as much, its environmental benefits align with Changi’s goal of net-zero emissions by 2050.
Neste, a global leader in renewable fuels, operates one of the world’s largest sustainable aviation fuel (SAF) and renewable diesel refineries in Tuas. The trial supports Singapore’s broader push for sustainable fuel adoption, including a passenger levy to fund SAF use from 2026.
If successful, renewable diesel could become a permanent fixture in Changi’s fleet, and a model for airports worldwide.
