Waste Management


The AA targets to reduce/recycle/recover 50% of all waste by 2021.

Waste is one of Hong Kong’s most pressing environmental issues. The Airport Authority (AA) is addressing one of its most significant environmental impacts, waste disposal, through a number of programs which cover behaviour change, waste management studies and infrastructure solutions to improve reduction, recycling and recovery rates.

Our Story

Food Waste Recycling

Food Waste Recycling:

The AA’s food waste recycling programme was launched in 2003 by composting food waste collected from restaurants and lounges at terminals into soil conditioner for landscaping on the airport island.

In 2011, the AA expanded the scope of the food waste recycling programme to cover airport business partners, including restaurants and lounges operating in terminal buildings, as well as airline catering companies, hotels and cargo terminals. Currently, most of the collected food waste is sent to O.Park1. The rest is converted into fish food at an off-site plant. In 2017/18, over 2,000 tonnes of food waste from 17 airport business partners was collected for recycling.

HKIA Food Rescue Programme:

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.

Through the HKIA Environmental Fund, the programme was developed according to a 3-staged approach. In 2013, we sponsored Food Angel to purchase a refrigerated truck, and also covered operating costs to collect surplus food from our business partners on the airport island. In 2014, a central storage room was set up in the terminal building to collect more surplus food from catering outlets. In 2016, the programme was expanded to cover Tung Chung and Discovery Bay, while Food Angel also worked with Hong Kong Sheng Kung Hui to serve meals to the needy in Tung Chung. The programme has been continued as a service contract in 2018. This allows the HKIA Environmental Fund to support other new initiatives.

In 2017/18, Food Angel collected around 44 tonnes of surplus food and transformed it into over 58,000 hot meal boxes for distribution to the needy. Since the programme started, over 150,000 meals have been served.

HKIA Environmental Management Recognition Scheme

HKIA Environmental Management Recognition Scheme:

The AA established the HKIA Environmental Management Recognition Scheme to encourage its tenants and business partners to take direct responsibility for their own environmental management. The biennial scheme was first introduced in 2012 and held again in 2014.

The latest programme, launched in 2017, aims to encourage wider implementation of waste reduction and recycling measures. Over 100 retail shops, catering outlets, office tenants and cleaning contractors are participating in the scheme. The “Passenger Awareness Programme”, a newly introduced initiative, aims to raise similar awareness among passengers and the general public through various promotional and educational activities.

Municipal Solid Waste (MSW) charging pilot

Municipal Solid Waste (MSW) charging pilot:

The AA implemented a MSW charging pilot at HKIA between January 2018 and December 2018 to prepare its tenants and business partners for the future introduction of mandatory MSW charging in Hong Kong. The quantity of waste generated by individual tenants and business partners was tracked and measured to determine the possible charges incurred. A monthly mock invoice was issued to tenants and business partners, showing the quantity of waste disposed and the estimated MSW disposal charge. This is expected to encourage tenants and business partners to take charge of their waste disposal behaviour, and highlight opportunities to reduce and recycle waste.
