Waste classification in practice

From analytical data to reviewed waste classification under EU rules for hazardous waste.

For standalone waste classification

You can start with a lab report, create a waste batch, review how data is interpreted, and export a PDF. Guideline values, scenarios, and exposure pathways are not needed when the assignment is only classification of excavated material.

1

Create one batch per defined waste fraction

A batch is the unit being classified. It should match the waste consignment that will be handled, transported, or submitted to the receiver as one classification basis.

  • Keep different excavations, masses, or clearly different materials separate.
  • Choose mean or maximum concentration according to how the fraction should be assessed.
  • The batch status and PDF only apply to the selected fraction.
2

Add analytical data via lab import, Excel template, or manual entry

The parameter table is the reviewed input data used by the classification. Imports and templates are just different ways to fill the same table.

  • ALS and Eurofins files can be imported directly when the format is recognised.
  • The Excel template is useful when data needs to be cleaned or completed outside the system.
  • Manual entry works for individual samples, supplements, and control values.
  • Concentrations are entered in mg/kg. Blank cells mean the value is missing.
3

Review import warnings, reference substances, and aggregation

The review tab shows how data has been interpreted, which assumptions are used, and what the user needs to check before using the report.

  • Unimported rows may be caused by missing mapping, unit, or invalid value.
  • Less-than values are treated as LOQ and used as LOQ/2 during summing and aggregation.
  • Total concentrations may need classification against a default reference substance or a user-selected reference substance.
  • Missing CLP basis and substances outside automated classification are flagged before the report is used.
  • Parameters marked No automatic HP classification, for example some individual PAHs without a direct Annex VI link, are shown in the table and report but do not contribute to automatic HP4-HP14. No action is normally required. If the material is assessed as tar asphalt, creosote, or another PAH product, handle that as a separate assessment.

Complete manual HP assessments and export the PDF

The system calculates the HP properties that can be assessed automatically from concentrations and harmonised CLP classifications.

  • HP4, HP5, HP6, HP7, HP8, HP10, HP11, HP13 and HP14 are calculated from concentrations and CLP classifications.
  • HP1, HP2, HP3, HP9, HP12 and HP15 normally require separate assessment.
  • The PDF shows outcomes, substance details, warnings, assumptions, and manual comments.
5

Risk assessment and scenario parameters are not needed for standalone waste classification

Waste classification can be run independently of guideline-value calculation. This makes the flow suitable when you already have analytical data and only need a classification basis.

  • Risk assessment answers what can remain at the site.
  • Waste classification answers how a waste fraction should be handled if waste is generated.
  • The same project can contain both waste classification and a site-specific risk assessment, but they are separate tracks that do not share data or process.

Final check before delivery

  • The correct batch and aggregation are selected.
  • Import warnings are handled or commented.
  • Reference substances are reviewed.
  • Manual HP assessments are completed when needed.
  • POPs, asbestos, pH/free phase, and other special cases are assessed separately.
  • PDF comments explain the user's boundaries.
