Classification of hazardous waste

HazWasteOnline™ is web-based software for classifying hazardous waste. The software follows the latest Environment Agency guidance and European regulations and lets the user focus on what is in the waste and not how to do the calculations or keep up with the changing data.

HazWasteOnline™ provides waste producers, consultants, carriers and waste receivers with a simple, accurate and auditable tool for the classification of potentially hazardous and hazardous waste materials such as contaminated soils, filter cakes, sludge residues and wastes from organic processes.

Although the waste producer has the legal responsibility to classify any waste they produce, most classifications in the UK are done by the waste receivers.

  • Incorrect classification can drastically increase disposal/transportion costs,
  • It can potentially breach legislation, and
  • Having a transparent and defensible audit trail reduces a company's risks.

While the cost for non-hazardous waste disposal in landfill may be between £25 and £100/tonne (including Landfill Tax), the cost for hazardous waste disposal can be many hundreds of pounds/tonne higher. This isn't just due to 1) the charge for the waste disposal itself but also to 2) landfill tax of £80/tonne and 3) the relatively small number of hazardous landfills left in the UK (hence transportation costs can become very significant).

HazWasteOnline™ contains all 20 EWC chapters and all 4000 plus substances from Table 3.1 / 3.2 of Annex VI of Regulation 1272/2008 on the Classification, labelling and packaging of substances and mixtures (CLP). The Professional Edition lets the user define other waste stream and substance lists such as ones for a filter cake, a sludge or site X. It lets you analyse tens or hundreds of samples at a time and includes a function to cut-n-paste data from laboratory spreadsheets.

Hazardous Waste Classification tool

HazWasteOnline™ is an on-line web tool that allows subscribers to:

  • Utilise a default waste stream template suitable for contaminated soils
  • Create customised waste stream templates with different substances, default species and EWC chapter
  • Add their own substances
  • Use the cut-n-paste function to quickly transfer laboratory results from spreadsheets
  • Classify one, ten or hundreds of samples at a time
  • Re-run the classification based on new information or assumptions
  • See which substances are causing the hazardous classification
  • Ignore a hazard property or substance (but document why)
  • Detailed PDF classification reports

HazWasteOnline™ allows users to code and classify waste as defined in the EWC (European Waste Catalogue 2002) based on EC Regulation 1272/2008 on the Classification, labelling and packaging of substances and mixtures (CLP) and latest Environment Agency guidance (WM3). The system comprises an analysis and reporting web front-end, a calculation engine to model the regulations and a database to save the contaminants inputted and reports generated. The system is fully auditable and is maintained by us to reflect the latest changes in EC regulations and Environment Agency guidance.

Day 1: Hazardous Waste Classification

This course covers the waste regulations, agency guidance, waste classification using the chemical analysis of the waste including practical exercises and the use of HazWasteOnline™. The courses will be working with the new hazard classes, categories, statement codes and the new WM3 classification engine to bring delegates up to speed with the big changes that came in on 1st June 2015. It also discusses where WAC, sampling methodology and the CL:AIRE code of practice fit into waste classification. Attendees include waste producers, waste management companies, regulators and consultants.

Day 2: Advanced Waste Classification    

This advanced course covers basic chemistry, physical properties, choice of both appropriate substances and species for metals, use of the C&L Inventory database and IARC Monographs for researching substances not in the CLP, Hazard Statement codes, which species to use, incomplete CLP entries, in depth examination of oils and PAH's, choice and meaning of different lab test suites and includes practical exercises.


24 October 2016 - New report format, Wiki and ATP 9 published

Revised waste classification report to better present laboratory data and associated meta data including reason for selection of metal species. We have also added a Wiki to provide information on the selection of metal species and many other issues such as high pH in made ground. The substance data from ATP 9 also published

22 June 2016 - German language and a German waste classification engine added

We have added both the German language and a German waste classification engine "Vollzugshinweise Brandenburg (Erlass Nr. 5/1/15)" to HazWasteOnlineTM.

25 May 2015 - WM3 classification engine published

Following the publication of the Technical Guidance WM3 last week, we are pleased to release our new WM3 classification engine for use by our customers.
