NEA Issues Bidding for Feasibility Studies for the Semakau Landfill

Oct 2020

Singapore’s National Environment Agency (NEA) has issued a Request for Proposal (RFP) to study the technical feasibility of recovering mixed landfilled materials in the Semakau landfill. These comprise incineration bottom ash (IBA) and incineration fly ash (IFA) from waste-to-energy (WtE) plants and non-incinerable waste (NIW) from industries, which were landfilled at the Phase I cells of the Semakau landfill.

Semakau Landfill has been in operation since 1999. Phase I of Semakau Landfill has 11 landfill cells separated by internal bunds. Approximately 15 million tons of mixed landfilled materials have been disposed of in 10 of the landfill cells. Reducing waste generation is considered to be crucial to extending Semakau Landfill’s lifespan beyond 2035. A key waste reduction target in the Zero Waste Masterplan is to reduce the ash and waste sent to Semakau Landfill each day by 30% by 2030.

Through the RFP, NEA is looking to explore innovative solutions for prolonging the lifespan of Semakau Landfill and spur Singapore’s drive towards becoming a zero-waste nation.

According to NEA, there are possibilities of recycling a form of slag (called NEWSand) produced from municipal solid waste through a high-temperature gasification process. NEWSand has already been used to make concrete benches, a footpath in Tampines town, and the new concrete plaza in front of the Environment Building, and is being considered as a road base or sub-base material in road construction projects.
