Waste

Waste Soil Classification and WAC Testing

Most development schemes are likely to require soils to be removed as part of the initial groundworks including the installation of services, new foundations or soil remedial action. Bulk excavation of soils may also be required during enabling works where final formation levels may change, with excess soils required to be taken away. These soils would likely be classified as a waste. Under the new Technical Guidance WM3, one of the main responsibilities of the waste producer is to classify the waste before it is collected, disposed of or recovered in order to determine its hazardous properties.

The Technical Guidance describes the waste classification and assessment process as follows:

Steps to classify the waste:

  1. Check if the waste needs to be classified

  2. Identify the code(s) that may apply to the waste

  3. Identify the assessment needed to select the correct code

Steps to assess the waste:

  1. Determine the chemical composition of the waste

  2. Identify if the substances in the waste are ‘hazardous’ or ‘persistent organic pollutants’

  3. Assess the hazardous properties of the waste

  4. Assign the classification code








How can Lustre Consulting help?

Waste Soil Classification and WAC Testing

We can assist our clients with the waste classification and assessment process by recovering samples of the waste for chemical testing. The results of the chemical testing is inputted into a waste classification tool to determine whether it is hazardous or non-hazardous.

Once this chemical testing is complete, we can then carry out analysis in the form of a Waste Acceptance Criteria (WAC) test to determine which type of Landfill can accept the waste. It should be noted that a WAC test is only required if the waste material is going to landfill. Our experienced consultants are trained in recovering representative samples whilst avoiding cross contamination. You can also check out our Blog page on waste soils for a more detailed explanation of the process.
