What is O · PARK1?

O · PARK1, the first organic resources recovery centre, locating at Siu Ho Wan of North Lantau adopts anaerobic digestion technology to convert food waste into biogas (a source of renewable energy similar to natural gas) for electricity generation whilst the residues from the process can be produced as compost for landscaping and agriculture use.

O · PARK1 is capable of handling 200 tonnes of food waste per day.

What is Food Waste?

Food waste is any waste, whether raw, cooked, edible and associated with inedible parts generated during food production, distribution, storage, meal preparation or consumption of meals.

Different sectors of the community and the general public throw away about

3600

tonnes of food waste every day

which is equal to


About one-third comes from food-related commercial and industrial (C&I) sources and two-thirds from households.

Food Waste Challenge

The current practice of disposing food waste in the landfills is not a sustainable solution as it consumes valuable landfill capacity and wasting the useful organic resources. Therefore, the most efficient and environmentally sound method of recycling food waste is to build a network of dedicated recycling plants. We will soon commence the site search for development, and study the feasibility and requirements of other regional O•PARKs.

Process of Turning Food Waste to Energy

Self-sustainable energy and export of surplus electricity

The biogas generated from the anaerobic digestion process is turned into heat and electricity that can support the needs of the facility. When running in full capacity, about 14 million kWh of electricity can be exported to the grid per year, which is equivalent to the power consumption by some 3,000 households.

The decrease in use of fossil fuel for electricity generation together with the reduced amount of organic waste in landfills would prevent the emission of some 42,000 tonnes of greenhouse gas each year.

Food Waste Reception

Bio-Treatment & Power Generation

Clean Emission

After the anaerobic digestion process, digestate will be converted into compost. The facility can generate about 20 tonnes of compost per day as a by-product, where it can be used for landscaping and agriculture applications. This dramatically cuts down the quantity of food waste to be disposed of at the landfills.
