Changi Airport using renewable diesel made from used cooking oil

More than 10 per cent of Changi Airport Group's diesel-powered heavy vehicles are running on renewable diesel, made from used cooking oil from its F&B outlets, among other waste materials. They are part of a six-month trial to assess performance and efficiency. Early results showed that renewable diesel works as well as fossil diesel, but it is better for the environment. This comes as Singapore drives towards the goal for all vehicles to run on cleaner energy by 2040. Charlotte Lim with more.
