Abstract:
:Incinerators do not achieve a complete mineralization of organic constituents of municipal solid waste. Bottom ash (main solid residue from incineration process) still contains a small quantity of carbon (1 to 5% in weight). This study is about characterisation of the carboned fraction (without carbonates) present in Municipal Solid Waste Incineration (MSWI) bottom ash as well as its influence on the short and long-term behavior of bottom ash. Qualitative and quantitative characterisation of different carbon species (refractory carbon, labile organic carbon, water dissolved organic carbon, maximum extractable organic carbon and non extractable organic carbon) are realised with various analytical methods (DSC, GC/MS, liquid phase carbon analyser). In this work, whatever studied sample, the same proportion of labile organic carbon is mobilisable by water. This labile organic fraction corresponds to the maximum quantity of extractable carbon and refractory carbon to non extractable organic carbon. This fine characterisation of the carboned fraction has allowed the evaluation of the quality and the short- and long-term non negligeable influence of the organic reservoir present in MSWI bottom ash.
