What happens to nanoparticles when they become waste?

Aurélie JoubertFor the past twenty years, industry sectors across the board have been producing a wide range of nanomaterials. They have developed rapidly and with little in the way of regulation. This has led to a regulatory vacuum when it comes to the end-of-life management of these nanomaterials. Little is known about the environmental and health impacts linked to the future of this nanowaste.

IMT Atlantique researchers have therefore led two successive projects on the incineration of nanowaste as part of a research consortium: NanoFlueGas and Nano-Wet. The results confirm the persistence of certain nanoparticles after they leave the incinerator, in the form of effluent and ashes. Last April, the research consortium, made up of IMT Atlantique, INERIS and industrial partner Trédi – Groupe Séché Environnement, submitted its technical recommendations to ADEME. Researcher Aurélie Joubert, lead author of the Nano-Wet report and researcher at IMT Atlantique, provides a look back at how this pioneer program came about.
