Résumé :

The question of the composition variability frequently arises when evocating thetreatment or the eventual use of municipal solid waste incineration (MSWI) residues. This studyaims to estimate this assumed variability by following the composition of electrostaticprecipitator (ESP) fly ashes from MSWI day by day during one month. The samples compositionis determined by X-ray fluorescence and their mineralogy is analysed by X-ray diffraction. Theresults show that the concentration values of MSWI ESP fly ash elements remain in the range of2 σ (standard deviation) around the average. An ANOVA test also indicates that there is nosignificant effect of the time-period on the ESP fly ash composition. The results suggest thus alow variability of the ESP fly ash composition over a one-month period. A one-year campaignbegan in March 2010 to investigate the MSWI ESP fly ash composition over a longer period. Alow variability of the MSWI ESP fly ash composition would constitute an incentive for the useof such residues in, for instance, construction materials.
