The Keppel Seghers Tuas waste-to-energy (WTE) plant is Singapore’s fifth incineration plant. As part of a wider government strategy to monetise infrastructure assets in the city state, it is a pioneer project under the National Environment Agency (NEA)’s public-private partnership (PPP) model.
Using combustion grate and flue gas cleaning proprietary technologies, it converts 800 tonnes of solid waste daily to generate 22MW of green energy, reducing 90% of the volume of the waste in the process.
Occupying only 1.6 hectares of land, it is one of the world’s most compact WTE plants, and incinerates waste throughout the year. Together with the other WTE plant in Senoko, Keppel Seghers has the capacity to treat up to 47.6% Singapore’s incinerable waste 1.
Being both the operator and equipment supplier enabled Keppel Seghers to test, improve and increase the reliability of its solutions. Developed in 2006 and operational since October 2009, Keppel Seghers will operate and maintain the plant for 25 years under a contract awarded by the NEA.
To date, Keppel Seghers has delivered more than 100 waste and 360 water and wastewater treatment projects across 25 countries. Currently, four WTE plants handle all incinerable waste collected in Singapore – two of which are owned and operated by Keppel Seghers. The other two WTE plants are operated by the NEA. The WTE incineration plants produce 2-3% of Singapore’s power needs and studies are also in place to consider using the ash generated in waste incineration as road construction material – an existing application in Germany and the Netherlands.
1 According to the Ministry of Environment and Water Resources, 2.45 million tonnes of waste were sent for incineration in 2008.
