Utilization Properties of Ash and Slag

Gasification ash can be used depending on its composition as a construction material and can be a possible source of refractory materials as cement additives or even fluxing agent for other gasification processes. And, of course, disposal of ash or slag in landfills remains always the final, but undesirable option [10]. 

Ashes firom dry-ash moving-bed and fluid-bed gasification should always undergo a leachabilitjr test, as their degree of sintering or agglomeration varies and determines the incorporation of soluble substances.
