30 SEP 2021 (THU) GEOG2160: Virtual Field Trip at O · PARK1

A virtual field trip at O · PARK1 via live zoom was held on 30 September 2021. The field trip aims to introduce the operating mechanism of The O · PARK1 – esp. how the food waste is recycled and transformed into biogas and compost using anaerobic digestion & composting technologies. The biogas is then used as an energy to generate electricity for the internal use within O · PARK1.


A seamless live & interactive virtual learning experience is conducted with the cooperation of Professor Elvis Au (Deputy Director of the Environmental Protection Department of HKSAR Government), EPD officers of O · PARK1 and our GEOG2160 teaching assistants. The live guided tour video are almost like being there – students are taken to explore the facilities including the control room, the bunker, the anaerobic digesters, etc. In Q&A session, students actively engaged with the EPD officers in discussing the operation process including the food waste collection, waste treatment, system monitoring, and future public education.
