The National Environment Agency (NEA) has appointed a multi-disciplinary consultancy team (MDT) led by Black & Veatch and AECOM (BV-AECOM) for the development of its Integrated Waste Management Facility (IWMF).
The appointment will see NEA working with BV-AECOM to draw up the detailed engineering plans and design specifications of the IWMF. Tenders will also be called at a later date to appoint engineering, procurement and construction contractors to carry out the detailed design and construction of the IWMF. BV-AECOM will subsequently supervise the construction and commissioning of the IWMF, with construction of the IWMF expected to commence in 2019.
The IWMF is an integral part of the NEA’s long-term plan to meet Singapore’s solid waste management needs. It will be equipped with state-of-the-art solid waste treatment technologies to recover resources from waste and recyclables collected under the national Recycling Programme. Source-segregated food waste and will be co-digested with dewatered sludge from PUB’s Tuas Water Reclamation Plant (TWRP) to improve biogas production. Waste that cannot be recovered for recycling will be incinerated in a waste-to-energy facility for electricity production. The IWMF will be co-located with PUB’s TWRP to reap the benefits of a water-energy-waste nexus.
The IWMF will be built in two phases, and designed with an initial incineration capacity of 2,900 tonnes per day when the first phase is completed in 2024. The energy from the incineration process will be recovered to generate electricity to operate the IWMF and TWRP; while excess electricity will be supplied to the grid, sufficient to power 150,000 four-room HDB apartments. The current plan is to eventually increase the incineration capacity at the IWMF to 5,800 tonnes per day in 2027.
“The IWMF is an innovative solution to meet Singapore’s long-term waste management needs. It will feature advanced technologies to treat the nation’s solid waste, while maximising resource and energy recovery. When completed, the IWMF will be one of the world’s most resource and energy efficient solid waste management facilities”, said Mr Joseph Boey, project director IWMF, NEA.
 Sufficient to power 300,000 four-room HDB apartments.
