On 28 June, the AA organised an informative site visit for its representatives and 13 airport business partners to O · PARK1, Hong Kong's first food waste recovery centre. During the tour, participants observed the anaerobic digestion and composting technologies implemented at the facility to recycle food waste into biogas for power generation. Residue from the process is converted into compost for landscape and agriculture use.
In 2017/18, HKIA's airport-wide food waste management programme collected 2,029 tonnes of food waste from restaurants in the terminal and other business partners.
