ONG&ONG named as architect for IWMF Package 2

ONG&ONG has just been named Architect of IWMF Package 2, a new Integrated Waste Management Facility (IWMF) in Tuas Nexus, as part of a Joint Venture with UESH Holdings Pte Ltd (UESH) and China Harbour (Singapore) Engineering Company Pte Ltd (CHEC). The project will be co-located at the Tuas View Basin Site along with PUB's Tuas Water Reclamation Plant (TWRP) forming Singapore’s first integrated water and solid waste treatment facility.

The new facility will adopt an innovative plant layout and designs to make full use of the limited space available. The proposals were evaluated based on process design and optimisation, resource efficiency, Green Mark initiatives, plant layout and value for the cost. This phase of the development is expected to be completed by 2025.

The IWMF will be Singapore's primary means of treating source-segregated food waste with an estimated capacity to process 400 tonnes per day. Additionally, it will be able to process 5,800 tonnes per day of incinerable waste; 250 tonnes per day of household recyclables collected under the National Recycling Programme (NRP); and 800 tonnes per day of dewatered sludge from TWRP.

According to The Straits Times, the synergies resulting from the proximity of the IWMF and TWRP is expected to offer savings of more than 200,000 tonnes of carbon dioxide annually, equivalent to taking 42,500 cars off Singapore's roads. Burning the biogas generated from the co-digestion of food waste with used-water sludge will generate enough energy to power Tuas Nexus with any surplus exported to the national grid.
