Mineralogical analysis of MSWI bottom ash Citation for published version (APA): Mineralogical Analysis of MSWI Bottom Ash

Abstract Strict legislative limits in regards to contaminants make it difficult to use Municipal Solid Waste Incineration bottom ash (MSWI BA) in building materials or landfill it in the Netherlands. The purpose of this investigation is to determine the mineralogical composition of BA fines (0-4 mm) which is usually the most contaminated fraction. Knowledge about the mineralogy can help determine where contaminants are bound in the material and how they will react to treatment or application in concrete. The main methods employed are XRD and SEM-EDX and the identified mineral phases fall into the categories of inert incineration residue, incineration or weathering product. However, further research is needed to identify all phases to allow for a complete quantification using Rietveld refinement in the future
