Singapore, Zero Waste Nation by 2030

The Singapore government introduced a policy goal to become a Zero Waste Nation in which diverting food waste from the disposal will play a significant role.

Singapore’s new Integrated Waste Management Facility (IWMF) will be the world’s largest energy recovery facility. The plant design is based on the most advanced waste-to-energy technology. Strategically co-locating the facility next to a new water reclamation plant (Tuas WRP), it aims to achieve the highest energy efficiency and lowest greenhouse gas footprint.

IWMF will be able to treat more than 2.5 million tons of solid waste annually, that is five times the capacity of the largest European waste-to-energy facilities. The sludge incineration plant will also be among the largest in world with two large fluidized bed combustion systems.

The food waste facility prepares the waste for treatment by anaerobic digestion at Tuas WRP where a biological process breaks down the organic materials without requiring oxygen to produce biogas.

Biogas will be utilized at IWMF to improve steam quality and give rise to higher overall plant thermal efficiency. This will increase electricity production and enable IWMF to export more to the grid while allowing both facilities to be energy self-sufficient.

Moving forward, the co-digestion of food waste and used water sludge will be implemented at the new Integrated Waste Management Facility and Tuas Water Reclamation Plant; these facilities will collectively be known as the Tuas Nexus, which is scheduled to be completed in 2025.
