Hazard classification is complicated because of the complex and varying content of 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 danger, in addition to the obligation to meet legislation. But hazard classification tests are time consuming and costly.

Fast results
ECN has launched the free tool HazClass for a quick indication of the hazard classification of any material. On the website www.ecn.nl/hazclass anyone can enter the elemental content of any material. After clicking ‘calculate’, an overview is returned of possible risks in most of the EU hazard classes HP 1 through HP 15. An advice for further action is given such as additional tests that need to be done on the material to assess the actual dangers. Since the advice is based on a worst case scenario, one can be sure the material is not hazardous if the tool indicates so. This may save time and money for additional testing.

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 Tanya 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 and green. It can save extra costs for special handling and transport. 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 results are stored in a database at ECN for future use. “We are offering our experience in hazard classification with this free tool,” says Klymko. “Additionally, we can offer our expertise and knowledge to execute any additional hazard classification testing that may be necessary.”
