What Happens to a Disposable Razor After You Throw It Out
The HONE Team
Short answer: almost nowhere good. American sorting lines are built to miss objects under two inches across. So a razor in the recycling bin is landfilled as residue, at the plant's expense. In the trash it has roughly a one-in-five chance of its steel coming back.
The rule nobody told you about.
Plastic at one end, steel at the other. Both get recycled every day, in volume. So the recycling bin looks like the obvious place for a used razor, and plenty of people put it there.
There is a rule that settles this before the materials matter. It is written in inches.
Recyclers call anything under two inches in at least two dimensions small format, and small format is understood to be lost. That is the Association of Plastic Recyclers' working definition. It is also the one MIT's Environmental Solutions Initiative used when it went looking for where small plastics go in 2023. Its researcher toured a sorting plant in Maine and watched them fall off the conveyor belts.
Now hold a disposable razor sideways. About five inches long, an inch and a half across, a few millimetres thick. Two of those three numbers are under two inches.
That is the verdict, and nobody had to look at what the thing is made of.
None of this was ever explained to you. It isn't moulded into the handle. It isn't on the lid of the bin. The rule lives in a design guide written for packaging engineers, and the people who read it are designing shampoo caps.
Why the line is built that way.
A single-stream recycling plant is a sequence of machines, each built to recognise one thing. Material passes hands first. Then screens that sort by size and shape. Then a blast of air that lifts the light stuff off the heavy stuff. Only after all that does it reach the magnet.
Read that order again, because it is the whole story. The magnet is the one machine that would recognise a blade, and it sits downstream of the screens. The razor leaves the line before it ever gets there.
And it leaves in the least dignified way available. The 2025 small-plastics study from the Center for the Circular Economy notes that long thin items spear through screens. They arrive end-on and slip between the discs. A razor is a five-inch spike with a handle.
Where the decision gets made.
The screen gap is the size of the rule. Anything narrower leaves the line here, before the magnet.
"they're just small pieces of metal" — a shaving forum, 2009
The three places it can end up.
Whoever wrote that wasn't wrong about the metal. He was wrong about the building.
Follow the razor past the screens and there are only three destinations. Each treats the steel and the plastic differently.
| Where it goes | The steel | The plastic |
|---|---|---|
| Curbside recycling bin | Drops into the glass stream, then leaves as residue the plant pays to bury | Same journey, same hole |
| Landfill | Stays. Steel doesn't rot and nobody digs for it | Stays |
| Waste-to-energy plant | Survives the furnace, pulled from the ash by magnets | Burned for power |
| Mail-back program | Separated by hand and actually recovered | Recovered, at the cost of posting it |
Notice what the table says about the first row. The curbside bin is the one destination where nothing comes back and somebody else gets a bill.
One number is deliberately missing. Search this subject and you'll be told Americans throw out two billion razors a year. That figure comes from a 1990 federal handbook. When a trade magazine asked the EPA about it in 2019, the agency said it no longer tracks disposable razors and has no newer estimate. Thirty-six years is too old to quote as a fact.
Which bin does better, and by how much.
Here is the arithmetic, with the assumptions in the open.
In 2018, the last year the EPA published a full account, Americans sent 146.1 million tons of waste to landfill and 34.6 million tons to waste-to-energy plants. Combustion is therefore 19% of everything thrown out. A bit under one in five.
Of the steel that reaches one of those plants, magnets recover roughly 85 to 95% from the ash. That range comes from a 2019 review by the environmental engineering institute at Rapperswil. Magnets catch pieces above about two millimetres, and a blade is twenty times that in its long direction.
Multiply it through. A razor in the trash has about a one-in-six chance of its steel being melted down again. In the recycling bin that chance is as close to zero as these things get.
Three assumptions hold that up. We assumed your trash follows the national average, which it doesn't — these plants cluster in a handful of states, so your real number is either far better than 19% or flatly zero. We used European data for the ash, because no American figure is published. And we assumed nobody plucks the razor off the line by hand.
So the useful question was never is this recyclable. It was does my city burn its trash or bury it. That one has an answer.
If it burns, the trash bin is where the steel has a future. If it buries, nothing you do with that razor matters, and the only move left is to stop producing them. Your county's waste page tells you which you're in.
The goal here isn't a zero-waste bathroom. It's knowing which bin is telling you the truth.
"last razor I ever bought — 7 years and counting" — a customer review
The one takeback that exists.
Gillette funds a mail-back program through TerraCycle. It accepts razors, cartridges and loose blades of any brand, not just theirs. You open an account, fill a box, print a label and pay the postage.
It works, and it is the only route in the United States that reliably returns a cartridge's steel to circulation. Three caveats. You pay the shipping, so a half-empty box defeats the point. Enrolment can be waitlisted. And wrap loose blades first — a person opens that box, which is why How to Dispose of Razor Blades Safely exists.
The part a different razor changes.
All of the above comes down to one property. A disposable razor is several materials fused into one object too small to sort. BIC's own engineers said as much in a 2019 patent application, which notes that handles are moulded from fossil-based thermoplastics and that the products "are fully discarded after their use". The patent was an attempt to fix that. It was withdrawn.
A three-piece safety razor is the same problem taken apart. The handle never enters the waste stream, because you keep it. The blade leaves on its own, as a flat piece of steel with nothing bonded to it — the one razor component a magnet can do something with.
What it does not do is make a blade curbside-recyclable. A double-edge blade is 43 by 22 millimetres. Under two inches in two directions: same rule, same result. The claim is narrower than you'd like — a safety razor takes the plastic out of the arithmetic and routes the steel somewhere recovery is mechanically possible. It doesn't solve the blade. Nothing on the market does.
FAQ
Can you put a disposable razor in the recycling bin?
No, and it is the worst option available. The razor falls through the sorting screens into the glass stream, where it becomes residue the plant pays to send to landfill. It gets buried either way, with a handling cost attached.
Is it better to throw a razor in the trash than in the recycling?
For the steel, yes, marginally. About 19% of discarded American waste goes to a waste-to-energy plant, where magnets pull ferrous metal from the ash. That gives a razor in the trash roughly a one-in-six chance of its steel being recovered, against effectively none in the recycling bin.
Does Gillette's razor recycling program work?
Yes, with conditions. It accepts all brands of razors, cartridges and blades, and it is free to join because Gillette sponsors it. You pay the postage, enrolment can be waitlisted, and shipping a half-full box defeats much of the point.

Where we're an interested party: HONE makes a stainless steel safety razor, so an article concluding that fused plastic-and-steel objects can't be sorted lands in our favour. The product section says plainly what a safety razor doesn't fix.
On who funds the research: the MIT small-plastics work was sponsored by consumer-goods companies including Procter & Gamble, which owns Gillette. The TerraCycle mail-back program is funded by Gillette. Both are cited for what they state factually, not as independent assessments of their own products.
On the arithmetic: the 19% combustion share and the one-in-six figure are ours, calculated from the EPA tonnages and the Rapperswil recovery range. Their assumptions are stated in the body, not buried here.
What we left out: the two-billion-razors figure, because its only traceable origin is a 1990 handbook the EPA has since disowned as a current estimate. Also any American ash-recovery percentage, because we couldn't find one published.
Quotations are real and attributed to no individual: the first from a 2009 shaving-forum thread, the second from a published customer review of a single-blade razor.
