SINGAPORE - Up to half of Singapore's waste treatment could be done at a single facility in Tuas by 2024.
Its ability to handle towns' solid waste, recyclables collected under the National Recycling Programme, food waste and treated sewage sludge together will enable authorities to extract more energy and resources from the waste, said the National Environment Agency (NEA) on Tuesday.
The integrated waste management facility will also be co-located with national water agency PUB's new Tuas water reclamation plant, to minimise both facilities' land footprint and boost efficiency.
The waste facility could generate electricity for the water plant, which will include an integrated Newater factory, and receive treated used water from it for cooling and washing.
The Tuas plant is part of the second phase of Singapore's Deep Tunnel Sewerage System (DTSS). The system, to be completed by 2022, uses tunnels to convey used water by gravity to reclamation plants. It will free up land now occupied by used water infrastructure. PUB and NEA said in a joint press conference on Tuesday that a joint team made up of engineering firm Black & Veatch and design and consultancy firm Aecom has been chosen as the lead consultant for the DTSS Phase 2 and waste facility projects.
