HazWasteOnline™ contains a number of “classification engines”. An engine is used to process the laboratory results and generate a standard PDF classification report that includes the List of Waste code, the data and a listing of any hazardous properties that the waste may have. An engine is simply a set of rules that enacts the stipulations contained in a particular technical guidance such as the UK’s WM3.
Each time the guidance changes, i.e. the rules changes (e.g. thresholds, calculations, cut-offs etc.), a new classification engine is built to reflect the changes in the guidance. A classifier should use the current classification engine for the jurisdiction wherein the waste is going to be disposed.
The current classification engines are summarised in the following table.
| Engine Name | Guidance | Data Source | List of Wastes | Unknown Oil |
|---|---|---|---|---|
| WM3 v1.2.GB | WM3 | MCL List | UK LoW | Yes |
| WM3 v1.1.NI | WM3 | CLP Table 3 | UK LoW | Yes |
| EU WM3 v1.1.NI | WM3 | CLP Table 3 | EU LoW | Yes |
| EU/2018/C 124/01 | EU | CLP Table 3 | EU LoW | No |
EU Classification Engine
HazWasteOnline Classification Engine: EU/2018/C 124/01
The current technical guidance for the classification of waste in the EU is Commission notice on technical guidance on the classification of waste – Note 2018/C 124/01.
This engine uses the substance data (Harmonised Entries) published in the CLP’s Annex VI, Table 3 and the EU’s List of Waste.
The EU guidance has the same rules and thresholds as WM3; however, there are a few differences with respect to List of Waste entry designations and no help for unknown oils.Edit
WM3 Classification Engines
HazWasteOnline Classification Engine: WM3 v1.2.GB
The current technical guidance to be used for the classification of waste that will be disposed of in England, Scotland or Wales.
This engine uses the substance data (Mandatory Entries) published in the HSE’s Mandatory Classification and Labelling list (MCL List) and the UK’s List of Waste
HazWasteOnline Classification Engine: WM3 v1.1.NI
The current technical guidance to be used for the classification of waste that will be disposed of in Northern Ireland.
This engine uses the substance data (Harmonised Entries) published in the CLP’s Annex VI, Table 3 and the UK’s List of Waste.
HazWasteOnline Classification Engine: EU WM3 v1.1.NI
This engine follows the WM3 guidance and is suitable for the the classification of waste that will be disposed of in EU countries. Most EU customers use this WM3 based engine rather than the EU engine because it allows them to classify unknown oils (“TPH”) in their waste; while utilising the European List of Waste.
This engine uses the substance data (Harmonised Entries) published in the CLP’s Annex VI, Table 3 and the European List of Waste.Edit
Changing Engines / Working in two jurisdictions
Classifiers working in different jurisdictions will need more than one Classification Engine.
For example, if you are working in Northern Ireland, you might need:
- the WM3 v1.1.NI engine – for classifying waste that will be disposed of in Northern Ireland
- the WM3 v1.2.GB engine – for classifying waste that will be disposed of in England, Wales or Scotland.
To allow this flexibility your company would have to purchase both engines.
