Incinerators Are the Landfills of the Sky
In our last article, Dehydrators Are the Chemical Fertilisers of Waste Management, we argued that a machine's output is the whole point, and that drying waste into sterile powder gives nothing back. A dehydrator at least leaves you something to hold. This time we want to talk about the option that leaves you less than nothing.
Incinerators… aka the landfills of the sky.
An incinerator doesn't process waste, it deletes it. Everything of value inside — the carbon, the nitrogen, the nutrients that were trying to become soil — goes up the chimney. You pay for fuel to destroy a resource, you inherit toxic ash and invisible emissions, and you run a machine that only works if your waste problem never gets solved. A landfill hides the problem in the ground. An incinerator hides it in the air.
A Problem Moved, Not Solved
Landfills were never a solution. They were a delay. Bury the waste, cover it, let it become the next generation's problem, leaking methane and leachate the whole time.
Incineration makes the same move in the opposite direction. Instead of putting the problem in the ground, it puts it in the sky. The waste appears to vanish, and on paper the problem is solved. But matter doesn't disappear when you burn it. It changes form and address. A pile you could see becomes gases you can't, plus a residue of toxic ash you still have to bury somewhere. The landfill hid the problem where you couldn't smell it. The incinerator hides it where you can't see it. Neither dealt with it.
The Mixed-Waste Multiplier
Here's what makes the reality worse than the brochure. These machines are sold to burn residual waste, but in practice they're fed unsorted, mixed waste, because separation at source barely exists here yet. That changes everything.
Burn clean organic material and you get smoke and CO₂. Burn mixed waste, and you're burning plastic, PVC, packaging, coated paper, batteries, and whatever else was in the bin. That's where dioxins, furans, and heavy metals come from. The US EPA states plainly that only small amounts of chlorinated material in waste are needed to support dioxin formation when it's burned.¹ Small-scale burning of mixed plastic waste has been found to pose greater risk to human health than large landfill fires, because it happens more often, closer to people, with less dilution.²
The problem isn't just that burning is bad. It's that burning the actual waste stream Indonesia produces — unsorted and plastic-heavy — is the worst-case version of it.
The Health Cost Is Immediate, Not Just Long-Term
The dioxin-and-cancer argument is real but slow, and it lets people file the risk under "someday."
The nearer truth: people living beside these units get sick now.
Documented effects of inhaling smoke from burning mixed waste include aggravated asthma and bronchitis, headaches, nausea, eye, nose and throat irritation, and cardiac effects from fine particulate matter (PM2.5 and PM10) small enough to reach the lungs and bloodstream.¹ A Human Rights Watch investigation into open waste burning found residents nearby reporting health problems consistent with sustained smoke inhalation, with children, the elderly, and people with existing heart and lung conditions most exposed.³ These are the people living next to the TPST — often the poorest, rarely consulted, never compensated.
Stabilisation Is Hard. Combustion Is Harder.
Burning waste safely is precision engineering sold as a bonfire. To suppress dioxin formation you need consistently high, controlled combustion temperatures, controlled airflow, flue-gas scrubbing, and safe disposal of toxic ash. Miss one and you're running an open fire with a warranty.
And who checks? Indonesia lacks readily available domestic dioxin testing, and the rules require dioxin monitoring only once every five years.⁴ For most units in the field, the claim "our emissions meet standards" is unverifiable. Nobody is measuring. Nobody can.
This Isn't Theoretical. It Just Happened Here.
In December 2025, the Ministry of Environment (KLH) sealed incinerators at TPST sites in Badung, Bali. By early February 2026, 12 units belonging to the Badung government sat shut down — eight at PDU Mengwitani, four newly procured at TPST Padang Seni for around Rp 4.8 billion — because KLH's emission testing found the exhaust exceeded air-quality limits.⁵ ⁶ The Minister tied the decision to health considerations and noted the same action had already been taken against incinerators in Bandung after they were shown to cause serious environmental harm.⁵
The most telling detail: the local government's defence was that it had tested emissions regularly with Sucofindo. It didn't matter. The machines were burning mixed, unsorted waste, and the Minister was explicit that modular incinerators risk producing dioxin and furan when combustion temperature isn't stable.⁷ The seal was later conditionally lifted — but only on the condition that waste be sorted to a single material type first, exactly the upstream separation the machines were sold to make unnecessary.⁷
Billions of rupiah of public money, bought to solve a crisis, sitting idle behind a government warning sign. That is the incinerator business model meeting reality.
The Incentives Run Backwards
An incinerator only works if you keep feeding it. In Europe, plants have been shut down because waste reduction left them without enough fuel to run.⁴ Build one, and you've built something financially dependent on never reducing, reusing, or composting. Every kilo you divert is a kilo the machine can't have. Indonesia's largest environmental organisation, WALHI, has argued this repeatedly, and that the budget belongs upstream: separating waste at source and reviving the sorting facilities already built and left to rot.⁴
The Trick Is the Shortcut
Here's the sell, every time. A landfill is full, waste is piling up, people are angry, and someone arrives with a machine that makes it all disappear. One purchase. No sorting, no separation, no changing how anyone behaves. Feed it everything, and the problem is gone by morning.
That's the trick. It has always been the trick. Landfilling was the same promise with a hole in the ground instead of a chimney. The appeal isn't that burning is good. The appeal is that it lets you skip the work.
But every material in that mixed bin already has a better ending than the fire, and burning erases all of them at once.
Glass melts down and comes back as glass, endlessly, with no loss in quality.⁸ Aluminium recycles on roughly 5% of the energy it takes to make it new — a 90–95% saving — and most aluminium ever produced is still in circulation.¹⁰ ¹¹ It recycles repeatedly with no loss of quality.⁹ Steel recovers at 60–74% less energy than making it from ore.¹¹ For paper, glass, steel and aluminium, life-cycle studies find recycling beats incineration on environmental impact even when the incinerator is a high-efficiency energy-recovery plant.¹² Organics want to become soil in 24 hours. Every one of these is value sitting in the waste stream, waiting to be recovered.
Burn the mixed bin and you destroy all of it in one motion. The glass, the metal, the nutrients — gone, converted to ash and gas you now have to manage. You didn't dispose of waste. You disposed of the recoverable material inside it, and paid diesel for the privilege.
So this is the plea, and it isn't about who you buy a machine from. Don't fall for the shortcut. When someone tells you one box solves everything that you want to throw out, they are selling you the same thing the landfill salesman sold your grandparents, repackaged with a cleaner brochure. The real work — separating at source, recovering each stream, composting the organics — is harder, less glamorous, and it doesn't fit on a single invoice. It's also the only thing that has ever actually worked.
The waste isn't the problem. Throwing away the value inside it is. Stop letting people sell you the match.
Frequently Asked Questions
Is incineration the same as recycling or composting waste?
No. Incineration burns waste into gases, particulates, and ash. Nothing is recovered. Composting uses aerobic microbial decomposition to turn organic waste into living compost that rebuilds soil. One destroys the resource; the other keeps it in the cycle.
Are "smokeless" incinerators safe?
A clear stack is not evidence of clean emissions. The most harmful outputs, dioxins and fine particulates, are invisible. In Badung, machines that passed the operator's own Sucofindo tests still failed KLH's emission standards and were sealed. Most "smokeless" claims cannot be independently verified because Indonesia rarely tests for the dangerous compounds.
Isn't burning residual waste fine, even if composting handles the organics?
Only if the waste is genuinely sorted, which in most of Indonesia it isn't yet. Fed mixed waste, incinerators burn plastics and produce dioxins and heavy metals. The Badung seals were lifted only on condition that waste be separated to a single material type first.
Why do some governments still choose incinerators?
They look like a fast fix when landfills close and waste piles up. But they treat the symptom, lock the buyer into feeding the machine, and, as Badung shows, can be shut down overnight when they fail emission standards. The durable solution is separating and processing waste at source, starting with organics, which are 60% or more of the stream.
