The Tuas South Incineration Plant is the largest such plant in Singapore. It was built at a cost of S$900 million on 10.5ha of reclaimed land and enables all incinerable waste generated in the country to be disposed by incineration. According to the Singapore’s National Environmental Agency, the countr y has experienced a sixfold increase in the amount of solid waste disposed from 1,260 tonnes a day in 1970 to a peak of 8,338 tonnes a day in 2014. Singapore’s solid waste management begins at homes and businesses. Prior to sending solid waste for incineration, recyclables are sorted and retrieved for processing. Statistics reveal a high level of construction and metal waste generated by industries (see Table 1). Incineration reduces the volume of solid waste by about 90%. Currently, Singapore’s solid waste disposal infrastructure consists of four waste-to-energy (WTE) plants, namely Tuas, Senoko, Tuas South and Keppel Seghers Tuas as well as the Semakau Landfill. Incinerated ash and other nonincinerable wastes are transported to the Tuas Marine Transfer Station and sent to the Semakau Landfill by barges. The Tuas South Incineration Plant (TSIP), completed in June 2000, is the largest such plant in Singapore. It was built at a cost of S$900 million on 10.5ha of reclaimed land and enables all incinerable waste generated in the country to be disposed by incineration. TSIP has been designed with an incineration capacity of 3,000 tonnes per day and power generation capacity of 80MW of electricity. About 20% of the power is recovered for in-plant use. 29 SPECIAL REPORT TUAS SOUTH INCINERATION PLANT
