Metal-free mineral fraction can be used in building industry. We analysed BA samples from two MSWI plants with the aim of characterising their composition. The BA samples were sieved into eight size fractions. With the exception of the smallest fraction (under 2 mm), the size fractions were sorted using magnetic separation, manual separation and a set of grinding and sieving processes. The results showed that the material composition varies with the bottom ash particle size. The bottom ash samples contained 10–24 % of glass, 2–3 % ceramics and porcelain, 0.2–1.0 % of unburnt organic matter, 1.3–2.0 % of nonferrous scrap and 15–24 % of magnetic fraction included ferrous scrap. The sorted ferrous scrap formed 1–9 % of all bottom ash weight. The results suggest that bottom ash from both incinerators can be potentially reutilized further.
