Bottom ash is composed of inert, non-combustible materials that are left over after the combustion process: sand, stones, and ash from burnt material, this is the so-called mineral fraction, which makes up 80-85% of IBA, and can be utilised as filling material for construction purposes (as a sub-base material in road construction substituting virgin gravel material, or concrete products, decreasing demand for energy-intensive concrete production).
IBA also contains metals that come from composite products, which makes them difficult to recycle such as nails in wooden objects, zippers in clothes, copper wire bits, and stainless-steel ballpoint pen tips. In fact, 10-12% of IBA is composed of ferrous metals and the remaining 2-5% is non-ferrous metals (of which 2/3 aluminium) (More in CEWEP Factsheet on Incineration Bottom Ash). All these materials can be extracted from the ash and further used as raw material at a lesser environmental cost than the production of virgin materials."
