management in Semakau Landfill and visited the site to understand how solid waste and sewage sludge are disposed there. Semakau Landfill was commissioned in April 1999 and is Singapore’s only landfill for waste disposal. Ash from the incineration plants and non-incinerable waste, such as construction and renovation debris, are disposed at the landfill. The landfill covers a total area of 350 hectares and has a capacity of 28 million m 3 when filled to the perimeter bund level with permanent capping. The bund is lined with impermeable membrane and a layer of marine clay to ensure that the water collected in the landfill due to rainfall and the filing of ash is contained within the area and treated at a wastewater treatment plant. Other ancillary facilities were also built on the island to ensure self-sustainability of the landfill operation.
