Abstract

In view of sustainable innovation, the development of nanotechnologies requires a deep insight in the nanosafety during the whole life cycle of products containing nanomaterials, from production to recycling and final destruction. No peculiar approved procedure exists for the waste management of nanoobjects at their end of life, due to the so far regulatorily unrecognized nano-specificity of such emerging products. The French NanoFlueGas project (2011-2014), supported by ADEME and led by INERIS, will examine nanosafety during the final destruction of nanomanufactured products by incineration, i) to understand possible mechanisms of nanoparticle release during combustion, and ii) to evaluate the efficiency of current pollution control devices. This project benefits from the know-how of both the ECOLE DES MINES DE NANTES GEPEA laboratory, a main academic partner specialized in engineering, and TREDI-SÉCHÉ ENVIRONNEMEN, a major expert of hazardous wastes incineration. The initial efforts focused on: i) identifying possible sources containing nanomaterials; ii) selecting three representative nanomaterials; and iii) providing small-scale incineration devices as close as possible to real scale installations. The experimental part is twofold. First, a deep insight is provided on the emission mechanisms and on the characterization of nanoparticles in the smokes (particle number, size, chemical composition, morphology...) during incineration at both pilotscale and on industrial units. Secondly, the NanoFlueGas consortium will review the efficiency of main available pollution abatement processes, thus providing fully adapted recommendations on procedures and technological features for the whole processing of nanowastes. Herein, we describe the different steps of the project, providing preliminary results.
