Incincerator Bottom Ash (IBA)
Incinerator Bottom Ash (IBA) has been used in The Netherlands already since 1981 as a certified product as an unbound material in groundwork and civic engineering projects to replace sand and gravel; for instance as embankment material in sound walls or roads, or for the redesign of former landfill sites (tips).
The use of Incinerator Bottom Ash (IBA) fits nicely in a circular economy. In The Netherlands, there is an annual need for 120 to 140 million tons of building materials, which are for the main part imported from abroad. By using Incinerator Bottom Ash (IBA), a saving is achieved on the use of primary raw materials, which prevents our living environment from being further negatively affected.
