Waste Acceptance Testing

The Landfill Directive requires that before waste can be sent to landfill all of the properties of the waste that determine its suitability for landfill must be known. The introduction of the Waste Acceptance Criteria (WAC) aims to obtain greater control of the waste disposed of at landfills, in order to minimise the impact of this form of disposal. Wastes can only be accepted at a landfill if they meet the relevant Waste Acceptance Criteria (WAC) for that type of landfill.

There is a significant cost implication if the waste is classified as hazardous, so waste producers - including those producing waste from construction sites - need to determine the classification of their waste before disposing of it to landfill.

At ACS Environmental Testing we can offer an efficient and reliable analysis service using the test leaching procedures (BS EN 12457) specified by the Environment Agency. The leachate produced by this procedure is analysed, and the results can then be compared with Waste Acceptance Criteria to determine the appropriate class of landfill to accept the waste

Analysis conducted in compliance with Environment Agency document “Guidance on Sampling and Testing of Wastes to Meet Landfill Waste Acceptance Procedures”.
