At the present time, no particular treatments are used for end of life nanostrutured products. It doesn’t exist specific incineration sector. Concerning this specific risk, the efficiency of existing fume purification processes has been not demonstrated.

Throughout this project, three types of wastes have been studied: a carbon powder waste, a polymer waste (doughy solid) and a liquid paint waste. The gross issues produced by the wastes in the combustion phase have been studied before purification. During the combustion process, a nanostructured aerosol is emitted regardless of the studied waste.

The incineration doesn’t always eliminate the nanostructured characteristic of wastes. Some nanocharged can be transferred to the raw gaseous effluent.

The various studies demonstrate the interest to use as treatment system of gross issues, baghouse filters associated to sorbent injection. In the case of a nanocarbon aerosol, this process retains in the better conditions more than 96 % in number of carbon nanoparticles issued in the fumes.

The achieved results raise other questions in particular in term of solid residue management, residual solids from the purification of fumes.
