Connect material origin, production and recovery across global supply chains
Collect multi-tier supplier evidence, trace metals and critical materials through processing, and share the information customers, authorities and recyclers need. Circularise connects material records across suppliers, production sites and finished products while controlling access to commercially sensitive information.

Know your material exposure
Identify which metals and critical materials enter your products, where they are extracted, processed or recycled, and which suppliers and production stages are involved.
From source to finished product
Maintain traceability through production
Keep material identity and supporting evidence connected as materials are refined, alloyed, cast, processed, split or combined.
Customers and market access
Reuse evidence across requirements
Prepare material records that can be used for procurement, product passports, environmental disclosures, audits and international trade requirements.
Explore metals and critical raw materials
Aluminium
Trace alloy composition, primary and secondary inputs, smelting and casting locations, and environmental evidence across transport, construction, packaging and other value chains.
Explore aluminium passport requirementsCritical Raw Materials
Connect extraction, processing and recycling information to supply-risk assessments, responsible sourcing and product-level requirements, including permanent-magnet information.
Explore CRM traceabilityWhat Circularise covers
Material traceability is only as strong as the evidence behind it
Material information is spread across producers, processors, traders, recyclers and manufacturers. The challenge is keeping that information connected as materials change form, ownership and location. Circularise brings supplier evidence, material flows and governed disclosure together so that information remains usable across production, customer relationships and recovery.
Collect supplier evidence
Gather structured information and supporting documents from material producers, processors, recyclers and component suppliers across multiple supply-chain tiers.
Trace materials and transformations
Connect materials to suppliers, production sites, heats, batches, processing steps, components and finished products through an auditable chain of custody.
Share information with supporting evidence
Provide customers, auditors, authorities and recyclers with the information they need while managing access to confidential supplier, production and transaction data.
Implementation workflow
Move from fragmented supplier records to maintained material traceability
Material traceability works best as an ongoing data workflow. Clear ownership and connections between records allow teams to respond to new requests without reconstructing the supply chain each time.
- 1
Collect the evidence
Map information requirements to materials, products, suppliers and internal owners. Collect origin, composition, processing, recycled-content and environmental evidence in a consistent format.
- 2
Trace materials through production
Link supplier evidence, production sites, heat and batch histories, transformations and product identifiers. Maintain those connections as incoming materials become intermediate materials, components and finished products.
- 3Outputs
Share the right information
Make relevant information available through customer disclosures, product records, Digital Product Passports and controlled partner access, with supporting evidence linked to its source.
Data to prepare
Build a material record that remains useful downstream
The precise fields depend on the material, product and applicable requirement. Organise information around material identity, production history, environmental evidence and supply risk so that it can be maintained and reused.
Material identity and provenance
Create a consistent record connecting each material to its composition, origin and responsible suppliers.
Material classification, grade, alloy and chemical compositionCountries and sites of extraction, processing and recyclingSupplier, producer and production-site informationHeat, batch, material, component and product identifiers
Production and chain of custody
Preserve the links between incoming materials, processing steps and outgoing products.

Circularity, environmental and recovery information

Supply risk and sourcing evidence
Turn upstream information into a basis for sourcing decisions and continuity planning.

Connected product and market requirements
Prepare product and material information
Product requirements increasingly depend on evidence from upstream suppliers. Forthcoming ESPR measures for iron, steel and aluminium, and targeted permanent-magnet requirements under the EU Critical Raw Materials Act, create different information needs across material value chains.
Explore Digital Product PassportsConnect environmental and circularity evidence
Supplier and production data can inform carbon-footprint calculations, applicable CBAM reporting and recycled-content disclosures. Keep each output linked to the calculation method, scope and evidence required by the relevant framework.
Explore environmental and material data requirementsRespond to international sourcing and trade requirements
Maintain reusable evidence on material origin, processing locations, composition and transactions for customer procurement, sourcing requirements and applicable trade measures across markets.
Explore tariffs and trade evidenceMaterial traceability readiness
Prepare the information before the next requirement or customer request arrives
Teams need a clear answer to the same question: where does each material data point come from, and which records substantiate it?
- 01
Confirm your material and market scope
Identify the metals, critical materials, products, production sites and markets to prioritise, together with the customer and regulatory requirements relevant to them.
- 02
Prioritise upstream evidence
Start with extraction, processing, recycling and supplier information. These records sit deeper in the supply chain and are often the hardest to reconstruct later.
- 03
Map transformations and data ownership
Identify where material identity changes, which records connect incoming and outgoing materials, and who is responsible for maintaining each data point.
- 04
Connect systems and access rules
Plan connections with ERP, PLM, LCA, procurement and quality systems. Define access for customers, auditors, authorities and recyclers according to the information they need and applicable requirements.
Practical guidance, requirements and evidence from material value chains
All resourcesFrequently asked questions
Do all metals and critical raw materials require a Digital Product Passport?
No. Requirements depend on the product and applicable legislation. Iron, steel and aluminium are prioritised for product-specific ESPR measures, while the CRMA establishes targeted information requirements for specified products containing permanent magnets. Material traceability also serves customer, sourcing and recovery needs beyond mandatory passports.
How does material information connect to finished-product passports?
Material records can provide composition, origin, recycled-content and environmental evidence for downstream products. Connecting those records to the relevant batches, components and product identifiers allows manufacturers to reuse upstream information in the format required for their products.
Can the same evidence be used for carbon reporting, recycled-content claims and trade requirements?
Much of the underlying supplier and production evidence can be reused. Each output still needs to follow its own calculation method, scope and verification requirements. Keeping those distinctions visible makes the records more useful across different requests.
