The flagship facility maximizes green technology and innovative design to establish new standards on how waste resources are managed in Singapore.

The Integrated Waste Management Facility (IWMF) is a state-of-the-art flagship facility that is an integral part of the National Environment Agency’s (NEA) long-term plan to tackle Singapore’s solid waste management needs.

A multi-disciplinary consultancy team led by AECOM and Black & Veatch, in association with Ramboll, is drawing up engineering plans and design specifications. The team will provide professional owner’s engineering services in project management, supervision of the construction works and commissioning of the IWMF.


“The plant will enable the island nation to reap the benefits of energy and resource recovery maximization for years to come. When completed, it is anticipated to establish new standards for how waste resources are managed and harnessed, with an emphasis on high-efficiency green technologies and innovative design.”

Tay Hin Guan, Vice President, Water & Urban Development at AECOM


Integrated facilities

The Waste-to-Energy (WTE) facility within the IWMF will be designed with an incineration capacity of 5,800 tonnes per day (tpd) making it one of the largest in the world. In addition to the treatment of incinerable waste, the IWMF will also process source-segregated food waste, household recyclables and dewatered sludge from an adjacent used water treatment plant, the Tuas Water Reclamation Plant (TWRP).

The co-location of the IWMF with the Public Utilities Board’s (PUB) TWRP is the first time two large-scale advance solid waste and used water treatment facilities have been planned from the ground up. The two operations will realize various synergies as compared to building two standalone plants. They will also optimize land use footprint and help free up land for other developments in land scarce Singapore.

The IWMF has been developed in two phases, with Phase 1, comprising a WTE facility, a materials recovery facility, food waste treatment facility and a sludge incineration facility expected to be completed by 2024.

The co-located IWMF and TWRP will be the first of its kind that is being planned from ground up. It will enable NEA and PUB to reap the benefits of a water-energy-waste nexus.
