Waste Acceptance Criteria (WAC) testing is a separate step from waste classification. Representative samples are analysed through an appropriate accredited laboratory to assess leaching behaviour and the acceptance evidence requested for the intended landfill or receiving route.
When this service is used
Used after waste has been appropriately characterised and classified, where a landfill, treatment facility or other receiving route requests WAC evidence before accepting the material.
What the report normally includes
- Review of the proposed receiving route and the WAC evidence requested
- Sampling and laboratory suite scoping for the relevant waste stream
- WAC leachate testing through an appropriate accredited laboratory
- Interpretation of results against the intended acceptance route
- Advice on segregation, further testing or alternative disposal routes where required
What we need from you
Providing the right information at the start helps us confirm the scope, quote accurately and avoid back-and-forth once the work is underway.
- Waste type, source and estimated volume
- Existing waste classification and laboratory data where available
- Proposed landfill or receiving facility if known
- Stockpile, source-area or excavation information
- Required disposal programme and turnaround
Useful to know before you enquire
Common questions
Is WAC testing the same as waste classification?
No. Waste classification determines the waste code and hazardous status. WAC is a separate acceptance test used where a receiving route requires leaching evidence.
Do I always need WAC testing?
No. It depends on the disposal route and the receiving facility's requirements. We can review the intended route and existing data before arranging unnecessary testing.
Do you use an accredited WAC testing laboratory?
We coordinate the agreed WAC suite through an appropriate accredited laboratory and can also arrange representative site sampling where required. The exact methods and parameters depend on the waste and receiving route.
What happens if the material fails the intended WAC route?
The next step may involve segregation, further characterisation, a different treatment or disposal route, or discussion with the receiving facility depending on the results and waste type.
