The aim of good waste management is to push waste up the hierarchy with landfill as a last resort. However given the current sorting technology, heterogeneous residues called Fines are created, they are considered at the present time as non-sortable and non-recoverable sent to second class landfills. A previous conducted study has revealed that fines contain several problematic substances for an inert classification. This article summarizes the most important problematic substances in fines for their acceptance inert landfills. These substances were identified by analyzing several samples collected from a siting of non-hazardous solid waste in the region of Rhône-Alpes in France. Eluate Analysis and fines analysis were conducted in order to identify the presence of any component that could prevent the classification of fines in an inert landfill. The obtained results were compared with the limit values for waste acceptance in an inert landfill. The study concluded that the six top-ranking problematic substances are Copper, Mercury, Antimony, Chloride, Fluoride and Sulfates, this study gives additional information on the origins of these substances that deserves particular attention to better limit their presence in the input of fines stream.展开更多
