Recycled aggregate: evidence before use

“Recycled aggregate” describes where a material came from, not whether a particular delivery suits a particular layer. Before it is accepted into a groundworks package, connect the product information to the project specification, the intended use and the records that accompany the load.

This buyer-side guide is about receiving and tracing an already-produced aggregate product. It is not a waste classification, testing method, material approval or recommendation to use recycled material in every application. The project’s designer, specification and environmental requirements control the decision.

Start with the project requirement

Write down the layer or application where the aggregate is intended to go and quote the controlled specification reference. Identify the required product description, grading or other characteristics, source restrictions, testing evidence and approval route from that document. Do not infer a product class or acceptance value from a supplier’s general catalogue description.

Check that the proposed source and product are the ones the project has reviewed. If a submission refers to one product but the delivery ticket names another, pause the acceptance process and ask the responsible technical or commercial lead to resolve the mismatch. Keep the delivery segregated if that is what the project procedure requires. A visual check can identify an obvious difference, but it cannot establish all performance properties.

Match each load to the product evidence

For each delivery, retain the order reference, supplier, source or production site where identified, product name or designation, delivery date, quantity and the project area or stockpile receiving it. Link the ticket to the relevant approval, product declaration, factory production control or test evidence that the project requires. The applicable evidence depends on the product, intended use and contract, so avoid demanding one generic certificate for every aggregate.

For an England project, check the Environment Agency’s quality protocol for aggregates from inert waste against the actual product and intended use. You cannot use its existence as approval for every recycled aggregate.

At our check on 15 October 2026, the Environment Agency lists the aggregates protocol as needing revision, with the task and finish group set up and the revision process ongoing. Industry can continue using the protocol while it is being revised, until a new resource framework is agreed or the protocol is withdrawn. Check the live review status again before procurement because that position can change.

Check the live frameworks collection before procurement. For projects elsewhere in the UK, confirm the applicable position with the relevant national regulator.

If a supplier says a product is no longer waste under a particular protocol or framework, ask for the product-specific evidence and the basis of that claim. Do not assume that a load is a non-waste product solely because it is recycled, has been processed or is accompanied by a delivery ticket. If no applicable framework or protocol covers the situation, the Environment Agency’s guidance on checking whether material is waste describes the separate assessment route. Seek advice from the responsible environmental professional where the status is unclear.

Keep storage and placement traceable

Separate products and sources where the project requires it. Mark stockpiles with enough information to connect them to the delivery records, and keep the stockpile location on the site plan or delivery log. If loads from different sources are mixed, record the event and obtain the project decision on whether the resulting material can still be used as intended. Do not rely on memory to reconstruct which source went into which area after the next layer is placed.

At placement, connect the load or stockpile to the area, layer, date and relevant inspection or test record. A delivery ticket proves that a delivery took place; it does not prove that material was installed in the location shown on a drawing or that it met every project criterion. Keep actual test results and the named reviewer decision as separate records.

Resolve discrepancies before the material disappears

Use a clear exception path for a missing ticket, wrong product name, damaged load, unexpected visible material or absent evidence. Record the load reference, location, observation, photographs if permitted, person notified and the decision that follows. If the load is rejected, reclassified, quarantined or accepted subject to conditions, preserve the actual decision and its authority. Do not let the person receiving a lorry make a design decision by default.

Avoid blending an uncertain delivery into a larger stockpile before the issue is resolved. Once material has been spread, compacted or covered, separating it may be impractical and the records may no longer show where it went. The project’s quality plan should state who can accept a product and what happens when the evidence is incomplete.

Example: a ticket names a different production site

Suppose your fictional approved submission identifies product RA-1 from North Yard. The driver arrives with a ticket naming South Yard. Both yards supply recycled aggregate, but you have no evidence linking this load to the reviewed submission.

Record the actual ticket reference and receiving location. Ask the supplier to explain the source change, then refer the evidence to the project’s authorised reviewer before placement. Preserve the written decision with the original ticket.

You have identified an evidence gap, not proved that the material is defective. If the reviewer approves the source change, link the approval to this load and any revised submission. If not, follow the project’s agreed disposition process.

Build a simple evidence chain

A useful material record links four things: the contract requirement, the approved product or source, the delivery event and the installed location. Add any required product or environmental evidence, test results, non-conformance records and final disposition. Keep original documents and revisions in the agreed project system; a spreadsheet is an index, not the authoritative source for every certificate.

If the environmental review finds that the material remains waste, establish the applicable waste controls before receiving or using it. Ask the responsible specialist to check the permit or exemption position and duty-of-care records. Our construction waste classification and transfer guide covers the separate waste-side evidence.

Recycled material may be suitable for a project when the product, specification, evidence and approval route line up. It is not automatically the lower-risk or lower-cost option. Check the same project requirements that you would apply to another proposed material, then record the decision before placement.

Rospower Projects coordinates material traceability with the earthworks and groundworks sequence, so evidence remains connected to the area where the product is used. On a data centre project, the civils overview explains how groundworks connects to the wider power, drainage and access package.
