Recycling Incinerator Bottom Ash (IBA)

Diverting more material from landfill

Incinerator Bottom Ash (IBA) is what remains after all of the combustibles have burnt out. It consists of ash and non-combustible material such as metals, glass and ceramics. In general, IBA will amount to approximately 20 to 25 percent of the total weight of waste treated.

MVV do not consider this ash as a waste, in fact it is still a valuable resource. In accordance with the waste hierarchy, this resource can be recovered for recycling and reprocessing rather than going to landfill.

The IBA drops off the grate into a water bath for cooling before it is collected for further processing. Metals are removed for recycling and the ash is then graded by size to be used as a secondary aggregate for construction and civil engineering projects.
