In order to raise the awareness of organic waste recycling and ways of recycling in Hong Kong, a group of MSc Energy and Environment students and research degree students taking the course, SEE5114/SEE8114 Energy, Environment and Sustainable Development, led by Dr. Carol Lin, visited the Hong Kong Organic Waste Recycling Centre (HKOWRC) on 30 January 2016 (Saturday).
During the visit, students learnt about the operations of food waste recycling for the production of animal feed. Various demonstration projects are currently on-going in the site such as Greenplus Renewable Energy Project for Hydroponics Farm developed by CLP China, and aquaponics system for sustainable food production.
In the aquaponics unit, waste product of one biological system (e.g. waste from fish) is used for as nutrients in the secondary biological system. Integration of fish and plants generate renewable resources providing grower with multiple products. Water is reused and conserved by filtration and recirculation. Therefore, local food provides access to healthy environment and local jobs which bridge a circular sustainable economy.
