Full disclosure or nothing
Passport platforms ask for the complete specification, then expose it to everyone in the chain. There is no middle setting.

01 · Why it matters
EU asks you to prove it. Today that means handing it over.
The ESPR mandates Digital Product Passports with material disclosure. Publish your bill of materials and competitors can reconstruct years of R&D from it. Every workaround so far trades your IP for a certificate.
We protect your IP, not trade it.
The 25-year gap
An industrial asset put into service in 2026, retired around 2051. Will the certifier that signed it still be trading, and still hold the file?
A PDF cannot age
Static certificates describe the product as built, never as it stands after two decades of load, repair and retrofit.
The loop never closes
Recyclers learn which designs actually come apart. That knowledge dies in their yard instead of reaching your next revision.
02 · How it works
One record. Four tiers. The passport never forks.
The tier decides what a party is shown — not which copy of the truth they get. Navy protects, green proves.
Tier 1
Public
Anyone with the QR code on the product. Footprint, recycled content, state of health, end-of-life route.
Tier 2
Post-life interest
Recyclers and repairers. Opens by itself at decommissioning — no request queue to sit in.
Tier 3
Restricted
Regulators and auditors, scoped by jurisdiction and logged on every read.
Tier 4
Confidential
Design IP. Stays inside the OEM. Nothing leaves but a proof that the claim holds.
Step 01
Prove the threshold, not the recipe
"Recycled content ≥ 60%" is answered yes or no against your committed bill of materials, with a proof attached — the percentage, the supplier and the formulation never leave your systems.
Step 02
Built to outlive the vendor
Every lifecycle event is sealed as it happens, and the record can be checked independently by a third party — it does not require Circalo to still be operating, or to be asked for permission.
Step 03
Write end-of-life back
The recycler records what actually came apart. It lands on the same record, and your next design gets to read it.
03 · The platform
Built for the people who do the work
Four screens carry the whole loop: issue a passport, run disclosure, hand it to a recycler, and let the public read it from the QR code on the product.
Product screens · Illustrative data · Organisations and assets shown are fictional
04 · Industries
One platform, many industries.
Every industry has to report different things under a different regulation. Adding one to Circalo means deciding which data fields it needs and matching them to the rules it must satisfy. You still get the same platform and the same passport — not a separate product per industry.
| Industry | Regime | Fields | Status |
|---|---|---|---|
| Wind turbine blades | ESPR · blade material passport | 42 | Pilot-ready |
| EV battery packs | Battery Regulation · Annex XIII | 68 | In development |
| Textiles | EU textile strategy · draft | 31 | Regime mapped |
| Consumer electronics | ESPR · repairability | 47 | Regime mapped |
| Steel | EPD · EN 15804 | 26 | Regime mapped |
Manufacturers
File once, satisfy every regime you sell into, and keep the formulation off the wire.
Recyclers & repairers
Everything needed to process a material, released automatically at end of life. Nothing more.
Partners & integrators
One API and a regime mapping per vertical. Bring the industry, reuse the passport.
Aligned with

Circalo is designed to export to the passport formats European industry data spaces already consume, so adopting it does not commit you to a single ecosystem.
Questions
The ones we get asked most.
Do I have to replace my PLM or ERP?
No. Circalo takes a bill of materials and lifecycle events from the systems you already run, and produces the passport on top of them.
Why not just a shared database?
A database requires every party to trust its operator. A regulator in 2040 auditing a product built in 2026 has no reason to. Circalo is built so the record can be checked without trusting us, or asking us.
What happens to my passports if Circalo goes away?
The record and its verification remain checkable by a third party without our involvement. That is a design requirement, not a promise about our survival.
Who decides what a recycler can see?
You do, once, as policy. The passport then enforces it — including opening Tier 2 automatically at decommissioning, so recyclers are not queuing for approvals on a unit that is already on the ground.
Does Circalo verify that my data is correct?
No, and we will not claim otherwise. Circalo proves your declared data has not changed since you committed it. It does not independently verify that the declaration was correct in the first place — that remains your conformity assessment, and we are designed to sit alongside it rather than replace it.
How do I evaluate this properly?
Bring us a real bill of materials under NDA. We will map it to the regime you sell into, show you which fields go public and which stay confidential, and go through the technical detail with your team under NDA.
05 · Contact
Bring us a product and a deadline.
We will show you which fields go public, which stay confidential, and what a proof looks like on your own bill of materials. We reply within 48 hours. Technical detail is covered under mutual NDA.
