Online tool HazClass provides a quick hazard classification for waste materials

ECN just launched an easy to use tool for the hazard classification of any waste material according to EU legislation. The free tool uses the elemental content of the material to assess possible hazards based on a worst case approach.


Hazard classification is complicated because of the mainly unknown composition and the varying content of substances in waste materials. However, if we want to reuse waste in a circular economy, for example bottom ash as a building material, it is essential to ascertain that it poses no risks, in addition to the obligation to meet legislation. However, hazard classification assessments are time consuming and costly.

Fast results
ECN has launched the free tool HazClass for a quick indication of the hazard classification of any waste material. On the website anyone can enter the elemental content of any material. After clicking ‘calculate’, an overview is returned of possible hazards in most of the EU hazard properties HP 1 through HP 15. Since the advice is based on a worst case approach, one can be sure the material is not hazardous if the tool indicates so. This may save time and money for additional testing. An advice for further action is given such as additional assessments that need to be done on the material to assess the hazard properties in more detail and tailored to the specific material.

No unnecessary tests
Any owner or user of waste materials, from large waste management companies, to primary producers or shredder companies, is invited to try HazClass, says ECN researcher Tetyana Klymko, who developed the tool. “The tool can be used for any waste material as a good starting point for waste classification. It can help companies to prove that their materials are non-hazardous. It can save extra costs for special handling and transport that are needed for hazardous waste. And it saves a lot of time because the tool immediately indicates which additional testing needs to be done. Unnecessary tests are avoided,” says Klymko.

Additional expertise
After registration, a detailed report about the possible hazards including links to test methods can be obtained. The registered users can access their own data later for future use. “We are offering our experience in hazard classification with this free tool for a fast pre-screening of hazard properties.  Additionally, we can offer our established expertise and knowledge to execute any further assessment and testing that may be necessary.”, says ECN researcher environmental assessments André van Zomeren.
