Turning Waste into Treasure
Dedicated to improving air quality through the use of alternative energy, the Airport Authority (AA) has been promoting the use of biodiesel in its vehicles at HKIA for a long time.
Following rigorous trials, the AA selected biodiesel for its ability to deliver worthy environmental benefits without impacting the efficiency of the airport’s operations. In 2008, the AA joined hands with The University of Hong Kong to pilot two trials on five diesel vehicles. Results verified that B5 biodiesel significantly reduced dark smoke emissions by up to 50%, without affecting the performance of the vehicles operation. As an added advantage, existing AA vehicles required little or no modifications for biodiesel, allowing a swift and smooth transition with zero disruption to service.
In October 2009 the AA implemented B5 biodiesel as the standard fuel across its diesel fleet and set up a number of biodiesel refuelling points across HKIA.
Expanding its biodiesel ecosystem, the AA has facilitated recycling of waste cooking oil from airport restaurants since March 2008. Around 3,000 litres of waste oil are collected and recycled into biodiesel every month, helping to reduce greenhouse gas emissions, lower harmful air particles and conserve fossil fuels.
Implementing biofuels has allowed the AA to make a number of environmental, economical and industrial benefits to the wider economy by reducing HKIA's carbon footprint and supporting Hong Kong's local recycling industry – creating jobs and green alternatives for Hong Kong's sustainable development.
