Semakau, Singapore's Only Landfill, Is Filling Up
Semakau Landfill, opened in 1999 and now Singapore's only landfill, will run out of space by about 2035 at current rates, which drives the country's waste targets.
Topics: environment, economics
Example
What happened: Semakau Landfill opened on 1 April 1999 and is now Singapore's only landfill. Most waste is burned first and only the ash and non-burnable waste go there. Even so, the government says that at current rates Semakau will run out of space by around 2035. Its Zero Waste Masterplan aims to cut the waste sent to Semakau each day by 30 percent by 2030 and to reach a 70 percent overall recycling rate by 2030.
Use it for: land scarcity can force a society to change its consumption habits, because when there is nowhere left to bury waste, reducing and recycling stop being optional.
Why it matters: Singapore cannot simply open a new landfill as larger countries do; every tonne avoided extends Semakau's life, so the 2035 deadline gives policy and personal habits a concrete reason.
Limit: The 2035 date is a projection at current rates and can move as waste habits and treatment change; the overall recycling rate (52 percent in 2025) hides a household rate of only 11 percent, so the 70 percent target is far off.
Key facts
- Semakau Landfill opened on 1 April 1999 and is now Singapore's only landfill.
- At current waste generation rates, Semakau Landfill will run out of space by around 2035.
- The Zero Waste Masterplan aims to cut the waste sent to Semakau each day by 30 percent by 2030 and to achieve a 70 percent overall recycling rate by 2030.
How to use this example in a GP essay
Should individuals or governments take the lead in protecting the environment?
Claim
land scarcity can force a society to change its consumption habits, because when there is nowhere left to bury waste, reducing and recycling stop being optional
How the evidence supports it
Singapore cannot simply open a new landfill as larger countries do; every tonne avoided extends Semakau's life, so the 2035 deadline gives policy and personal habits a concrete reason
Limitation
The 2035 date is a projection at current rates and can move as waste habits and treatment change; the overall recycling rate (52 percent in 2025) hides a household rate of only 11 percent, so the 70 percent target is far off.
Relevance
It is the Singapore example tutors cite most for waste and consumption questions, and it links personal habits to a dated national limit.
Limitations
- The 2035 date is a projection at current rates and can move as waste habits and treatment change; the overall recycling rate (52 percent in 2025) hides a household rate of only 11 percent, so the 70 percent target is far off.
Evaluations
environment evaluation
Support
A single landfill with a known end date makes the cost of waste visible in a way most countries never face, which gives Singapore a strong reason to reduce waste at the source.
Counterargument
Burning waste before landfill saves space but releases carbon dioxide, so extending Semakau's life partly trades a land problem for an emissions problem.
Rebuttal
That trade-off is why the Masterplan targets less waste overall, not just more burning: cutting what is thrown away helps both land and emissions.
Additional support
Households lag far behind: in 2025 only 11 percent of domestic waste was recycled, against 67 percent of waste from industry and businesses, which points to where the next gains must come from.
economics evaluation
Support
Building a new offshore landfill or reclaiming land costs far more than reducing waste, so waste targets are also an economic choice for a land-scarce country.
Counterargument
Recycling is costly to run and depends on prices for recycled materials, so a high recycling target can be expensive if markets for those materials fall.
Rebuttal
The cost of recycling should be compared with the cost of a replacement landfill, not with zero; in a country with no spare land, the comparison favours waste reduction.
Additional support
Measures such as the 10-cent bottle deposit from 2026 put a price on waste, which uses incentives rather than appeals to change behaviour.
