Hong Kong Organic Resources Recovery Centre: transforming waste into renewable energy

Hong Kong has a reputation of food paradise that brings together cuisines from all around the world, yet it results in a significant amount of food wastage taking up as much as nearly 35% of total waste volume. As a matter of fact, food leftover is a quality organic resource. The Organic Resources Recovery Centre, built and operated by SUEZ NWS, is Hong Kong's first food waste recycling facility to capture this neglected resource.

The mission

Food waste on the rise

Hong Kong's waste production per capita is much higher than other advanced cities in Asia, especially food waste recorded with 3,600 tons per day in 2016. Without proper treatment, the biodegradable residue may risk the food security and ecosystem, therefore a state-of-art recycling and treatment facility for organic resource is needed.

food waste produced in Hong Kong everyday
Our solution
The Organic Resources Recovery Centre on Lantau Island, is Hong Kong's first of its kind food waste recycling project. It is able to treat 73,000 tons of food waste from restaurants and food factories annually. The project applies biological treatment, such as anaerobic and composting processes, to convert waste into methane gas and organic fertilizer. Coming into operation in Q1 of 2018, the plant is fully in accordance with the Chinese and EU standards, and the strictest safety and environmental requirements.
The results

The methane produced by the Organic Resources Recovery Centre can be used as renewable energy. It is expected to generate 14 million KWh of electricity per year, adequate for the use by 3,000 households meaning 25,000 tons of carbon reduction by using fossil fuel otherwise .
