TUAS SOUTH INCINERATION PLANT

Tuas South Incineration Plant is the fourth and largest refuse incineration plant in Singapore.
Built at a cost of S$890 million and completed in June 2000, it was designed to incinerate
3,000 tonnes of refuse daily. The plant is sited on 10.5 ha of reclaimed land and enables
all incinerable waste generated in Singapore to be disposed of by incineration. The Plant
was built with state-of-the-art technology. The various processes are highly automated
and controlled via a digital control system. Modern equipment incorporating advanced
technology is used in the plant to ensure a high level of efficiency and reliability.
Incineration achieves about 90% reduction in volume of the refuse. Hence, all incinerable
refuse are disposed of at the incineration plants while non incinerable refuse and ash from
the incineration plants are disposed of at the Semakau Landfill. This helps to conserve
the use of scarce land in Singapore. Tuas South Incineration Plant, together with the
other incineration plants and the Semakau Landfill, will meet the refuse disposal needs of
Singapore and help in achieving a clean living environment for all Singaporeans.
