Waste classification for soil - Data Management

This lunch time webinar will examine some of the mistakes and misunderstandings associated with the selection, transcription, use and classification of lab data and how an innovative development is 1) helping labs deliver a better product and 2) waste classifiers get a better, quicker and more auditable classification.


Waste soils are one of the largest waste streams in the UK. Classification is an important aspect of waste management. If this is not done properly, not only could you be prosecuted, but it will also cause delays to your projects and bring additional cost. This is particularly important as with the rate of standard landfill tax being just under £89/tonne and the recent changes in HMRC’s assessment of landfill tax, misclassification could cost even more.

Sampling and laboratory testing are the main ways to help understand which hazardous substances may be in a soil and at what concentrations. However workers who take a single sample of a waste and/or utilise a “standard” or incorrect test suite may not be doing themselves any favours.  Another overlooked issue is that no two lab’s results are necessarily the same (one lab’s TPH is another lab’s EPH) and can give the classifier significantly different outcomes. These issues can then be compounded by the classifier not spotting some of the subtleties in the lab data they are trying to use in their classification software, leading to poorer or incorrect classifications.


As no classifier can easily replace missing data, it is also important that the classifier (and critically, the person actually purchasing the lab testing) has an appreciation as to the significance of selecting (or not) the various lab tests. Another challenge relates to the errors associated with and the inefficiencies relating to the manual and/or the cut-n-paste entry of data into their classification software. A final issue is that the lab’s deliverables need to be more transparent and auditable. These last two challenges have been recently addressed by the development of a new data transfer format for waste classification (and WAC) data, a format that more and more soil labs are now offering.


This is the second of CIRIA’s lunch time webinar in 2018 on waste classification focusing on laboratory analysis and the management of information/data generated from the analysis.

Why attend?

To understand:

    • More about the lab tests that can help you better classify your waste
    • TPH, EPH, mineral oil, cleaned up or not - what do they really mean?
    • Moisture correction, dry weight and as-received results
    • The pro’s and cons of the different formats delivered by the labs
    • Some of the common mistakes people make working with lab data
    • How the new data delivery format is helping labs and classifiers offer a more robust solution
