Food Waste Management in HK

There is approximately 3,640 tonnes food waste produced in Hong Kong every day. About one third of them originates from commercial and industry (C&I) sector, and the remaining comes from households, representing 11% and 27% respectively of the municipal solid waste generated in Hong Kong. In recent years, the amount of disposal food waste from C&I sectors has been increasing, from 400 tonnes in 2002 to 1,033 tonnes in 2014.

The disposal of food waste, an organic waste which decomposes easily, to landfills is not sustainable as it leads to rapid depletion of the limited landfill space and formation of green house gases such as methane, and wastewater at landfills, imposing severe burden on our environment. The Environmental Protection Department (EPD) plans to develop the Organic Waste Treatment Facilities (OWTF) in phase. The OWTF will adopt biological technologies – composting and anaerobic digestion to stabilize the organic waste and turn it into compost and biogas for recovery. The first phase of the OWTF (OWTF-1), with a daily treatment capacity of 200 tonnes of source separated organic waste, is located at Siu Ho Wan. Its construction works is in progress and will be commissioned in 2017.
