Abstract (en)

[origin: WO2022200753A1] A method for treating an air pollution control residue (APCR) by creating a wet APCR mixture, promoting an exothermic reaction in the wet APCR mixture to create an APCR reaction product, adding an aqueous liquid to the APCR reaction product to form a diluted APCR reaction product, separating contaminants from the APCR reaction product in the diluted APCR reaction product by creating an aqueous solution of contaminants in the diluted APCR reaction product and a decontaminated APCR in suspension in the aqueous liquid and forming a solid decontaminated APCR product. The solid decontaminated APCR product being suitable for use as a grout material and/or as a suitable constituent of building materials including Portland cements.
