Here are the latest developments I can confirm based on recent reporting:
Semakau Landfill in Singapore remains Singapore’s only offshore landfill and is under continuous discussion about extending its lifespan beyond 2035 through waste reduction, recycling, and material recovery initiatives. Local coverage in 2025 highlighted concerns about waste disposal pressures and the ongoing emphasis on “saving Semakau” through the Zero Waste Masterplan and related trials.[1]
Government discussions in the past year have included exploring mining the ash remains (NEWSand) from incineration and investigating constructive reuse of ash and other waste streams to stretch Semakau’s capacity. These initiatives are part of broader plans to close the waste loop and reduce landfill dependency.[2][1]
There have been public statements and media briefings about the potential need for a new offshore landfill or additional capacity infrastructure in the longer term, should current waste generation continue at elevated rates. Specific timelines have been revised in the public discourse as waste disposal dynamics evolve.[1]
Longer-running policy context includes ongoing trials and proposals for recovering materials from incineration bottom ash or non-incinerable waste for construction materials or other uses, as well as continued investments under Singapore’s Zero Waste Masterplan.[5][2]
If you’d like, I can:
Mr Chua Kheng Wee Louis: To ask the Minister for Sustainability and the Environment (a) how is the 2035 lifespan of Semakau landfill determined; (b) in the past 10 years, how much of the waste generated is domestic waste versus industrial waste and what are their respective growth rates; and (c) what has been the reduction in waste generation since the launch of the Zero Waste Masterplan in 2019.

phys.orgSingapore's only landfill has 10 years left, and waste disposal rates are going up while recycling is down. The urgency to "save Semakau" or find alternatives is growing.

www.wildsingapore.com4 We are developing innovative ways to close our waste loop. NEA is conducting trials to turn incineration bottom ash into NEWSand, which can be used as construction material, so as to divert waste away from Semakau Landfill. Together with other initiatives under the Zero Waste Masterplan, we will work towards keeping Semakau Landfill from reaching capacity even beyond 2035.Back to top
