Waste Classification

Waste Classification 

As part of the Waste Duty of Care, it is a legal requirement for businesses to correctly classify the wastes they produce before they are collected, disposed of, or recovered.

The classification of waste must be carried out in accordance with the detailed methodology set out in the Environment Agency’s WM3 technical guidance, ‘Guidance on the classification and assessment of waste’. This involves designing a suite of analysis around the known source of the waste, and assessing the results against a range of hazardous properties. 

In addition, Waste Acceptance Criteria (WAC) testing is required to determine whether the waste can be disposed of to an inert landfill, a hazardous waste landfill, or within a cell for stable non-reactive hazardous waste.

Determining the best disposal route for waste requires detailed knowledge of waste classification and analysis methods. This is where Mayer’s skill and experience can help.

We routinely perform analysis to help clients properly determine the appropriate designation for waste. If necessary, we will challenge the Environment Agency over a stated classification if we feel there are grounds to do so.

Understanding the composition or ‘make-up’ of a waste stream is also the first step to grasping its potential as a resource. Once the compositional profile of waste has been established, it is possible to determine the processes required to recover value from it.

This type of characterisation/ profiling is also essential to understanding the content of waste following treatment, as it allows the recyclable/ recoverable content and calorific value of materials to be ascertained.

Mayer has the ability to undertake large-scale compositional analysis and recycling and recovery mass balances. In the past this has included:

  • Waste electrical and electronic equipment (WEEE)
  • End-of-life vehicles (ELVs)
  • Packaging
  • Moisture levels


Wet Waste Landfill Tax Discounts

Water added to waste as part of an industrial process can be discounted above certain levels to help reduce landfill tax payments. This requires an understanding of the operation giving rise to the wastes, how much moisture is naturally within the wastes and how stable the moisture content is over time. 

If you think you have a waste like this and you think you could reduce your landfill costs get in touch we would be happy to handle the applications and management of the discount on your behalf.

We have developed a strong relationship with Mayer over the years. Their understanding of our industry, diligence and commitment to achieving tangible results has meant that we can concentrate on other aspects of our business.
