Waste to energy and infrastructure firm Keppel Seghers and its Chinese partner, Zhen Hu, have been awarded a contract worth HKD 31 billion ($4 billion) for Hong Kong’s first integrated Waste Management Facility to be built on a reclaimed island off the coast of Shek Kwu Chau.

Keppel Infrastructure Holdings Pte Ltd (Keppel Infrastructure) and China Harbour Engineering Company Limited, through their respective subsidiaries, Keppel Seghers Hong Kong Limited (Keppel Seghers HK) and Zhen Hua Engineering Co. Ltd. (Zhen Hua) have secured the project to design, build and operate an Integrated Waste Management Facility (IWMF) off the coast of Shek Kwu Chau, which is to the south of Lantau Island, Hong Kong.

The contract was awarded via a competitive international tender called by the Environmental Protection Department (EPD) of the Government of the Hong Kong Special Administrative Region.

The project will bring together the strengths of two companies in their respective fields to deliver a world class waste management project. The Engineering, Procurement and Construction (EPC) phase will be undertaken by Zhen Hua, one of the biggest construction and reclamation companies in Hong Kong with strong civil and marine works experience.

The EPC phase will involve the reclamation of an area of about 16ha, design, engineering and construction of breakwaters, as well as of the IWMF, and its related port facilities on the reclaimed island.

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

Subsequently, Keppel Infrastructure Services will undertake the Operations and Maintenance (O&M) of the facility for 15 years after it is completed in 2024.

For its roles in the EPC and O&M phases, Keppel Infrastructure’s share of the total contract is approximately HKD 11.3 billion with up toan additional HKD 9.6 billion for escalation provisions and other contingencies.

Landmark Project

According to Keppel Seghers the IWMF is a landmark project for HK’s waste management. It is Hong Kong’s first integrated facility for municipal solid waste. As a key part of Hong Kong’s waste management strategy, it is able to reduce the total volume of waste treated at the facility by more than 90%, thus extending the lifespan of landfills.

Currently, Hong Kong landfills its non-recycled waste. The IWMF comprises a WTE Plant, a mechanical treatment plant and ancillary facilities, which include an administration building, visitor centre, port handling facilities, as well as and desalination and wastewater treatment plants.

Contracted to treat about 3000 tonnes per day of mixed municipal solid waste, the WTE Plant will feature Keppel Seghers’ proven WTE technology with its air-cooled grate, boiler design, and advanced combustion control system.

In addition, the WTE Plant will also use Keppel Seghers’ flue gas cleaning system, ensuring that the plant’s emissions will comply with Hong Kong and EU standards, which are amongst the most stringent international standards available. Capable of producing approximately 480 million kilowatt-hours (kWh) of gross electricity per year, the surplus electricity beyond plant consum

“The IWMF project reflects the Hong Kong government’s foresight and resolve to effectively and holistically address waste management,” said Dr Ong Tiong Guan, CEO of Keppel Infrastructure.

“Advanced waste incineration technology is able to meet stringent environmental standards and is hence one of the most widely accepted methods of waste management in developed markets,” he added.
