Waste Incineration Week1

What is the estimated year by which Singapore's only landfill, Semakau Landfill, is projected to be completely filled?

• 2025

• 2030

• 2035

• 2040

How is electricity generated from waste at Singapore's waste-to-energy plants?

• Through direct combustion of waste in gas turbines.

• By converting steam from waste incineration into electricity using turbine generators.

• Using solar panels powered by the heat from burning trash.

• By chemically breaking down waste to produce biofuel for generators.

What is the primary solid byproduct remaining after waste incineration, and what percentage of the original waste volume does it represent?

• Sludge, 5%

• Ash, 10%

• Compost, 20%

• Scrap metal, 15%

What is one environmental concern associated with waste incineration, and what is a proposed solution to mitigate it?

• High water consumption; solved by using seawater for cooling.

• Significant noise pollution; addressed by building plants in remote areas.

• Greenhouse gas emissions; mitigated by filtering flue gas and exploring ash recycling.

• Soil contamination; prevented by burying ash deep underground.
