Keppel Infrastructure’s subsidiary Keppel Seghers and China Harbour Engineering’s subsidiary Zhen Hua have secured a HKD31bn ($3.9bn) contract to design, build and operate an integrated waste management facility (IWMF) off the coast of Shek Kwu Chau, Hong Kong.

The contract has been awarded through a competitive tender called by the Environmental Protection Department (EPD) of the Government of the Hong Kong Special Administrative Region.

As part of the contract, th engineering, procurement and construction (EPC) phase of the project will be taken up by Zhen Hua. This phase will involve the reclamation of an area of about 16 hectares with design, engineering and construction of breakwaters, along with the IWMF and its related port facilities on the reclaimed island.

During the EPC phase, Keppel Seghers will supply its waste-to-energy (WTE) technology as well as WTE project implementation and execution of the mechanical treatment plant, power island and desalination facilities.

Following the completion of the construction in 2024, Keppel Infrastructure Services will undertake the operations and maintenance (O&M) of the facility for a period of 15 years.

Keppel Infrastructure CEO Ong Tiong Guan said: "Keppel is honoured to be able to contribute to Hong Kong's sustainable urbanisation through this iconic project, which reinforces Keppel's leadership for world class WTE technology and operations.

“We are proud that our WTE technology has been implemented around the world, building on our proven track record as a competitive and reliable waste management solution provider.”

The waste management facility is claimed to be Hong Kong’s first for managing municipal solid waste. As a key part of Hong Kong’s waste management strategy, it is expected to reduce its total waste treated at the facility by more than 90%, resulting in the extension the lifespan of landfills.

The new facility includes a waste to energy plant, a mechanical treatment plant along with ancillary facilities including an administration building, visitor centre, port handling facilities, as well as desalination and wastewater treatment plants.

This facility is expected to treat about 3,000 tonnes of mixed municipal solid waste per day.

Apart from this, the plant will also use Keppel Seghers' flue gas cleaning system, which ensures that the plant’s emissions comply with Hong Kong and EU standards.

The facility can generate about 480 million kWh of gross electricity per year and the surplus electricity that is left after plant’s consumption will be transmitted to the grid. The surplus electricity will be enough to be supplied up to 100,000 households, while reducing 0.44 million tonnes of carbon emissions per year.
