Narrative description of the project:

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.

Capable of producing approximately 480 million kilowatt-hours (kWh) of gross electricity per year.

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.
