Waste Management


To increase the recyclables recovery rate by 25% by 2025 compared to a 2018 baseline.

To support this new waste target, the Airport Authority (AA) adopts a three-pronged approach to waste management with an increasing focus on further improving separation of recyclables at source and post-disposal sorting to salvage more conventional and new types of valuable recyclables.

Our Story

Food Waste Recycling

Food Waste Recycling and Surplus Food Rescue

The AA launched the food waste recycling programme in 2003 and extended the programme to encompass the airport catering outlets operating in terminal buildings and business partners in 2011. The food waste collected through the programme is currently sent to the O · PARK1 for further processing, during which renewable energy and re-usable compost are generated. In 2020, over 700 tonnes of food waste was collected from tenants in terminal buildings and from business partners for recycling.

Also, the AA started the Hong Kong International Airport (HKIA) Food Rescue Programme in partnership with a local NGO, Food Angel, in 2013 to collect surplus food from restaurants and caterers at HKIA. Over the years, this programme has expanded to cover several major airport business partners and tenants. By working with Hong Kong Sheng Kung Hui, the surplus food collected is transformed into hot meal boxes for distribution to the needy in Tung Chung. In 2020, around 80 tonnes of surplus food was collected and transformed into over 130,000 hot meal boxes. Further details of the AA’s waste performance in 2020 are available in the AA Sustainability Report 2020/21.

Waste Reduction

The AA is offering a variety of new and revamped facilities at HKIA to encourage waste reduction and recycling efforts in passenger areas. In an effort to reduce the number of single-use plastic water bottles generated at HKIA, more than 100 drinking water fountains have been in use across the passenger terminal buildings so far; and additional water dispensers will also be installed across these buildings by 2022.

Moreover, additional hand dryers have been installed in the toilets at HKIA under an ongoing toilet revamp programme in 2021 to help reduce the use of paper towels. The upgraded toilets in T1 Satellite Concourse and the Limousine Lounge feature modernised designs with "one-stop" hand-washing and hand dryers within each basin unit to further encourage the use of less paper towels.

Artificial Intelligence Robotic Waste Sorter System

Artificial Intelligence Robotic Waste Sorter System

The AA completed a pilot trial of an Artificial Intelligence (A.I.) robotic waste sorter system at the T1 Midfield Concourse in 2021. The purpose of the trial was to test the capabilities, efficiency and limitations of the system for recovering recyclables from different waste streams at HKIA. The most optimal operating environment was identified for improving aspects of HKIA's waste recycling performance in the future.

Municipal Solid Waste Charging

Municipal Solid Waste Charging

The Waste Disposal (Charging for Municipal Solid Waste) (Amendment) Bill 2018 was passed by the Legislative Council on 26 August 2021. In order to prepare for the implementation of mandatory Municipal Solid Waste (MSW) charging in Hong Kong, the AA will collaborate with the tenants, airlines and airport business partners to implement the scheme with reference to the findings of the previous MSW charging pilot at HKIA, which was conducted between January 2018 and December 2018. Meanwhile, the AA is supporting those airport stakeholders to reduce and recycle waste as much as possible before disposal.
