How Acidless Recovery Supports Conflict-Free Recycled Gold
Gold recovered from discarded electronics can reduce pressure on newly mined resources, but its environmental benefit depends on how it is collected, processed, documented, and sold. A recycled gold claim is credible only when businesses can demonstrate where the material came from and how it moved through the recovery chain.
ALS2, the acidless separation technology developed by Ikoi S.p.A., addresses an important part of that chain. Designed for precious-metals recovery from electronic waste and WEEE streams, it offers a cleaner processing route while creating opportunities for stronger material records and controlled plant operations.
The technology does not issue a conflict-free certificate by itself. Certification remains the responsibility of an accredited auditor, recognised assurance scheme, refiner, or supply-chain organisation. ALS2 can, however, help recyclers produce reliable process evidence that supports responsible sourcing assessments and recycled gold verification.
What Conflict-Free Recycled Gold Means
Conflict-free gold generally refers to gold that has not contributed to armed groups, human rights abuses, or the financing of conflict. For recycled material, this status depends on more than the fact that the gold originated in waste. A recycler must establish that the input stream is genuinely secondary material and that it was not mixed with newly mined gold of uncertain origin.
Responsible sourcing frameworks usually examine the entire supply chain. They can cover supplier screening, country-of-origin information, transaction records, risk assessments, worker protections, environmental controls, and independent verification. The precise requirements differ between schemes, but all depend on credible evidence.
This distinction is important for electronic waste processors. A batch of printed circuit boards may contain gold, silver, palladium, and other valuable metals, yet its final product cannot automatically be marketed as conflict-free recycled gold. The claim requires traceability from collection and intake through dismantling, separation, refining, storage, and sale.
How ALS2 Strengthens Material Traceability
ALS2 uses an acidless separation approach to recover precious metals from electronic scrap and WEEE recycling streams. By avoiding conventional strong-acid treatment, the process can reduce reliance on hazardous chemical reagents and support a more controlled working environment. Its compact plant concept may also allow recovery operations to be located closer to collection or pre-processing activities.
A controlled process is valuable for chain-of-custody management. Operators can assign batch numbers to incoming materials, record weights and composition, document processing stages, and reconcile recovered output with the original feedstock. These records provide a practical basis for showing that gold was recovered from a defined waste stream rather than introduced from an undocumented source.
Process data can include supplier identity, collection location, material category, intake date, batch mass, output mass, recovery yield, and destination of the recovered precious-metal fraction. When supported by calibrated weighing equipment, laboratory analysis, photographs, purchase records, and inventory controls, such information becomes useful audit evidence.
From E-Waste Feedstock To Verifiable Gold
A credible recycled gold pathway begins before material reaches the recovery plant. Recyclers need procedures for approving suppliers and identifying the origin of electronic scrap. Commercial invoices, waste transfer documents, collection permits, dismantling records, and statements about ownership can help establish the legitimacy of the feedstock.
At the plant, physical segregation is essential. High-value electronic components should be stored separately from other waste categories, with clear labels and controlled access. If material from multiple suppliers is combined, the operator should record the blending event and retain a calculation showing how each source contributed to the resulting batch.
ALS2 can fit into this model by providing a defined recovery stage within a documented workflow. Its role is to separate and concentrate precious metals; the operator remains responsible for the records surrounding input material, plant controls, testing, storage, and onward transfer. This division of responsibilities keeps technology claims separate from certification claims.
The recovered output should also be tested and reconciled. Assay results help determine the concentration and value of precious metals, while mass-balance calculations compare input quantities with recovered fractions, process losses, residues, and stock. Unexplained discrepancies may indicate weak controls, inaccurate measurement, or possible material substitution.
Evidence Required By Responsible Sourcing Schemes
Certification bodies and downstream buyers commonly look for evidence that is consistent, complete, and independently reviewable. A process description alone is rarely enough. The operator must connect technical performance with documented sourcing and governance practices.
Relevant records may include:
- Supplier due diligence and risk-screening files
- Waste origin, transport, and ownership documentation
- Batch identification and inventory movement logs
- Weighing records, assay results, and mass-balance calculations
- Environmental, health, safety, and chemical-management procedures
- Sales invoices and transfer records for recovered precious metals
Frameworks such as the OECD Due Diligence Guidance, the LBMA Responsible Gold Guidance, and relevant Responsible Jewellery Council requirements can influence what buyers expect. Their applicability depends on the organisation’s role, the market served, the product claim, and the assurance route selected.
An auditor may inspect the recovery plant, interview personnel, sample records, observe stock controls, and compare reported production with purchasing and sales data. ALS2 documentation can support this review by describing the separation process, operating parameters, equipment controls, maintenance, and output handling. It should be presented as technical evidence within a wider due diligence system.
| Verification criterion | Contribution of an ALS2-based operation | Additional evidence normally needed |
|---|---|---|
| Recycled origin | Recovers precious metals from documented electronic waste and WEEE inputs | Supplier declarations, waste records, ownership documents |
| Chain of custody | Supports batch-based processing and controlled output handling | Inventory logs, segregation procedures, transfer records |
| Material identity | Produces defined precious-metal fractions for testing | Assay reports, sampling procedures, laboratory controls |
| Environmental performance | Acidless processing can reduce dependence on strong acids and related risks | Permits, environmental monitoring, safety records |
| Conflict-risk assessment | Enables a traceable recovery point within the supply chain | Country, supplier, human-rights, and sanctions screening |
| Certification readiness | Creates technical and operational evidence for an audit | Independent assurance against the selected standard |
Where The Technology’s Role Stops
It is essential to avoid overstating what an acidless recovery system can prove. ALS2 does not determine whether a supplier has committed labour abuses, whether waste was illegally exported, or whether an input batch was mixed with gold from a high-risk source before arrival. Those questions require due diligence, governance, and sometimes investigation beyond the processing line.
The technology also cannot replace legal compliance. A recycler may need waste-management authorisations, transport documentation, environmental permits, occupational safety controls, export records, and financial crime safeguards. Requirements vary by jurisdiction and by the type of electronic waste handled.
The strongest claim is therefore precise: ALS2 can support the recovery of precious metals from traceable secondary materials through a cleaner, documented process. A conflict-free or responsibly sourced statement should be made only when the complete supply chain meets the relevant standard and an appropriate assurance process confirms the claim.
Building A Defensible Recycled Gold Claim
A recycler using ALS2 can improve certification readiness by designing controls before commercial operation begins. The first step is to define acceptable feedstock, prohibited sources, supplier approval criteria, and procedures for investigating unusual transactions or incomplete documentation.
The business should then connect operational data with responsible sourcing policies. Every batch needs a clear identity, and every movement should leave an auditable record. Digital inventory systems can reduce manual errors, while photographs, barcode labels, access controls, and regular stock counts provide additional safeguards against substitution or loss.
Useful priorities include:
- Establish a documented supplier due diligence and risk-escalation procedure
- Separate, label, and track electronic waste from intake to recovered output
- Record weights, assays, yields, residues, and inventory adjustments for every batch
- Train staff in chain-of-custody controls, safety, human rights, and fraud awareness
- Select an independent auditor and standard before making market-facing claims
The final claim should match the evidence. Terms such as “recovered from WEEE,” “recycled precious-metal content,” and “responsibly sourced recycled gold” should not be treated as interchangeable. Marketing, product passports, customer certificates, and commercial contracts should state the basis of each claim and identify any limitations.
Why Acidless Recovery Matters For Buyers
Jewellery manufacturers, electronics companies, refiners, and component suppliers increasingly need evidence that their materials support circular-economy goals without creating new social or environmental risks. A recovery technology that reduces hazardous chemical dependence can strengthen the environmental side of that proposition, while traceable records address the provenance side.
The ALS2 project’s focus on compact precious-metals recovery plants is relevant to regional recycling networks. Shorter, more controlled routes from WEEE collection to recovery may reduce unnecessary transport and make it easier to preserve batch information. Local or decentralised processing does not automatically guarantee responsible sourcing, but it can improve visibility when operators apply consistent controls.
For buyers, the most credible supplier is one that combines technology, documented procedures, independent testing, and transparent limitations. Recycled gold becomes more valuable as a material claim when its origin, processing route, environmental performance, and custody history can be demonstrated together.
Businesses evaluating ALS2 for precious-metals recovery should therefore assess both the equipment and the management system around it. Review the intended feedstock, required permits, data architecture, assay arrangements, supplier controls, and selected certification framework as one connected programme.
