Waste Management

Waste is one of Hong Kong’s most pressing environmental issues and a challenge for HKIA. Our three-pronged approach to waste management includes reducing the amount of waste generated, facilitating waste separation at source to promote recycling, and exploring alternative disposal options. To accelerate waste reduction at HKIA, we continue to explore innovative ways through collaboration, research and technological development.

Our approach to waste management

Waste reduction at source

  • Minimise consumption to avoid disposal

Facilitation of recycling

  • Encourage recycling through engagement, improved facilities, and behavioural change

Alternative disposal options

  • Explore other disposal options as an alternative to landfilling

HKIA’s recycling performance

Key initiatives

Waste reduction at source

  • Reducing the use of paper towels in washrooms – We completed the installation of hand dryers at HKIA Tower. Five redesigned washrooms featuring basins with built-in hand dryers were opened in the passenger terminals. We will renovate 108 washrooms by mid-2021.

Facilitation of recycling

  • A.I. robotic sorter system – Preparations for a pilot trial using an Artificial Intelligence (A.I.) robotic sorter system commenced in 2019/20. The trial aims to identify the effectiveness, efficiency and limitations of using the A.I. robotic sorter system to recover recyclables from different waste streams at HKIA. We aim to kick-start the pilot trial in the Midfield Concourse in 2020/21.

Alternative disposal options

  • Supporting research into a circular economy – With funding approved from the HKIA Environmental Fund in 2018/19, The Hong Kong Polytechnic University commenced a second study on transforming starch-rich food and paper towel waste at HKIA into value-added chemicals.
