Andritz to supply flue gas treatment systems for IWMF in Singapore

Austria-headed international technology group Andritz AG has announced that it has received an order from Keppel Seghers to supply flue gas treatment systems for the Integrated Waste Management Facility (IWMF) Phase 1 waste-to-energy (WTE) project in Singapore.

IWMF and the Tuas Water Reclamation Plant (Tuas WRP) – collectively known as the Tuas Nexus – will be the world’s first integrated waste and wastewater treatment plant (WWTP) to be conceptualized and planned from the ground up. IWMF Phase 1 and the TWRP are scheduled for completion in 2025.

A Keppel Seghers-led consortium was selected by Singapore’s National Environment Agency to develop and build on an engineering, procurement, and construction (EPC) basis the waste-to-energy (WTE) and materials recovery facilities as part of the IWMF Phase 1 development for Singapore

Once completed, IWMF Phase 1 will be able to treat:

  • 2 900 tonnes per day of incinerable waste;
  • 250 tonnes per day of household recyclables collected under the National Recycling Programme;
  • 400 tonnes per day of source-segregated food waste; and
  • 800 tonnes per day of dewatered sludge from the Tuas Water Reclamation Plant

Andritz’s scope of supply for the four WTE lines in IWMF Phase 1 includes the design and supply of flue gas treatment equipment such as fabric filters, HCl and SO2 scrubbers, ID fans, low-temperature economizers with steam gas reheaters, steel structures, flue gas ducts, tanks and silos, and advisory services.

According to Andritz, it was chosen as the consortium’s key supplier for the flue gas treatment system due to its track record with dry, semi-dry, and wet technologies for industrial flue gas cleaning as well as its advanced energy recovery solution using heat recovery from flue gas in the low-temperature range.

These installations will help Singapore achieve its sustainability goals because they will be able to meet the highest environmental standards and reduce the emissions from incineration of 2 900 tonnes per day of incinerable waste.
