Apple 2026 Environmental Progress Report
Notes & sources
Forty percent of the display glass in Apple Watch Series 11 and Apple Watch SE 3 is recycled — recovered from post-industrial material, including iPhone scrap. It is a small number on a small screen, and it quietly bends a rule the glass industry has lived with for decades.
“We used 40 percent recycled glass in the display glass of Apple Watch Series 11 and Apple Watch SE 3 recovered from post-industrial material, including iPhone scrap.”
Why this is harder than it sounds
Your jam jar and your phone are both “glass,” and that is where the resemblance ends. Containers are soda-lime glass, forgiving by design — furnaces there run happily on 30, 50, sometimes 70 percent recycled cullet, and every batch of cullet cuts the heat and the carbon.
Cover glass on a watch or a phone is a different animal: a chemically strengthened aluminosilicate, mixed to a tight recipe, then ion-exchanged to put the surface under compression so it survives your pocket. A few parts per million of the wrong element — iron, a stray metal oxide from a coating — shows up as colour cast, haze, or a weak point that becomes a crack.
That is why the recycled content here is post-industrial, not post-consumer. It is factory scrap: offcuts and rejected panels from making display glass, plus iPhone scrap of known composition. The chemistry is traceable, the contamination is controlled, and the material never left the supply chain.
Getting glass back out of a used phone is the unsolved half. The display is laminated — glass bonded to adhesive, to a polariser, to an OLED stack — and separating it cleanly enough to feed a display furnace is not yet a thing anyone does at scale.
Purity
Display glass must be low-iron and near-perfectly clear. Mixed-stream cullet carries the contamination that ruins both.
Strength
Chemical strengthening depends on exact alkali content. Unknown feedstock means unknown drop performance.
Recovery
Adhesive, polariser and panel are bonded together. Clean glass separation from used devices is still largely experimental.
Volume
Less glass per unit, fewer parts, one supplier line. It is the sensible place to prove a material before it reaches a phone.
Published recycled content in cover / display glass
Only two consumer-electronics figures are publicly stated as recycled content in the glass itself. Everything else in your pocket and on your desk is, so far, silent on the subject. Container glass is shown for scale — it is the baseline the industry already achieves.
Read the two top rows carefully: they are not the same claim. Apple’s 40% is for the display glass of a specific watch. Corning’s 22% is for a glass formulation sold to many customers. Both are pre-consumer / post-industrial — neither means your old phone came back as a new screen. Yet.
Context
So — iPhone next?
Technically, nothing forbids it. The same post-industrial cullet that went into a watch face could go into a phone face; the obstacle is volume and validation, not physics. A phone ships in the hundreds of millions, drops onto pavements, and carries the brand’s entire durability promise on its front surface. Every percentage point of unfamiliar feedstock has to survive that.
Watch the three things that would signal it is coming: a post-consumer figure instead of a post-industrial one; a glass supplier — Corning, AGC, Schott — publishing a recycled-content grade rather than a one-off; and a teardown showing a display stack designed to come apart.
PCs and monitors are further behind, for an unglamorous reason: most of their sustainability reporting is written around aluminium enclosures, recycled plastics and ocean-bound polymers, because those are the materials the brand actually specifies. The panel — glass included — is bought as a finished module from a display maker, and the recycled-content question stops at the purchase order.
Which makes the 40% worth noticing. Not because a watch face changes the climate arithmetic, but because it is the first time anyone has had to answer the question out loud.
Sources & where to dig deeper
The primary source — the 40% claim
The hub for the Environmental Progress Report PDFs, product environmental reports and the 2030 roadmap. This is where the glass line lives, alongside the recycled cobalt, rare earth and aluminium figures.
Product announcements state recycled-content figures first, in plain language, on launch day — useful for pinning a claim to a specific model and date.
Where returned devices go, and what the disassembly robots actually recover. The counterpart to the recycled-content story: supply.
The glass itself
Maker of Gorilla Glass. Search “Victus 2” plus recycled content for the 22% pre-consumer figure, and the technical papers on why aluminosilicate batches tolerate so little unknown cullet.
Galaxy sustainability announcements, including the S23 generation shipping with recycled-content Gorilla Glass, and subsequent recycled-material claims per model.
Cullet fundamentals: furnace energy and CO₂ saved per increment of recycled glass. Container glass, not display glass — but it is the physics baseline everything else is measured against.
How much glass is generated, recycled, combusted and landfilled in the US. The ~31% container recycling rate comes from here.
The most honest picture of a display stack: what is bonded to what, and therefore how plausible it is that any of it comes back as feedstock.
Other makers — for comparison
Annual environmental report plus Pixel and Nest recycled-material commitments. Check whether glass is broken out separately or folded into “recycled content by weight”.
Surface device material claims and the Circular Centers programme — the closest PC-side analogue to Apple’s material reporting.
Detailed recycled-content reporting on plastics, ocean-bound polymers and aluminium across PCs and printers. A good test of how rarely display glass is mentioned at all.
The repairability extreme: a phone whose screen is designed to be swapped in minutes. Different route to the same problem — keep the glass in use rather than melt it.
Modular laptops with user-replaceable displays. Worth reading beside the recycled-content numbers: longevity and recycled input are two different levers.

The point
Forty percent of a watch face is not a solution. It is a proof that the question has an answer — and now someone has to ask it about the phone.
