Supplier evidence collection
Declarations, certificates, feedstock data and test results, structured and reviewed.
Plastics and chemicals
Circular-material data customers and regulators can use
Trace recycled, bio-based and bio-circular feedstocks from source to finished product. Manage mass balance and share evidence for REACH, CLP and PPWR, without exposing formulations.

What Circularise covers
A circular material is only as credible as its evidence
The certificate or declaration is the output. The work is collecting evidence, tracing allocations and linking attributes to each transaction.
Material and mass-balance traceability
Feedstocks, sites, transformations, inventories and transactions in one chain of custody.
Governed data sharing
Share evidence with customers, auditors and authorities, not formulations or supplier identities.
Implementation workflow
From fragmented declarations to a maintained material-data system
An ongoing workflow, not a spreadsheet rebuilt before every audit.

Frequently asked questions
What does plastics and chemicals traceability cover?
Feedstock origin, composition, certificates, production records, chain of custody and sustainability attributes across suppliers, sites and finished materials. The evidence supports certification, audits, customer disclosures and product requirements.
What is the difference between ISCC PLUS and a Digital Product Passport?
ISCC PLUS is a voluntary certification system for circular supply chains. A DPP is a product-linked record under EU product law. The same traceability data can support both, but their rules and outputs differ.
Can ISCC PLUS data be used for PPWR recycled-content requirements?
It can support a PPWR claim, but certification alone does not prove PPWR conformity. The Regulation sets its own calculation, verification and documentation rules.
How do plastics and chemicals connect to ESPR passports?
Polymer and chemical producers may be asked for composition, recycled content, substances of concern and end-of-life data, especially as rules develop for tyres, electronics and other priority products.
Who can access composition and formulation data?
Access follows the recipient’s role. Customers, recyclers, auditors or authorities receive verified material characteristics without the full formulation or supplier identities.
