ABSTRACT:
Smoke purification waste materials (SPW), rich in lime, are mixed with a product containing at least 60% silica and/or aluminum to bring the pH to a value of between 7 and 11.5 and with a quantity of water of between 15% and 160% of the weight of the waste materials and said product. In practice, the ratio of SiO.sub.2 and Al.sub.2 O.sub.3 over CaO must be at least equal to 0.8. Solid compounds are obtained that are virtually insoluble in water and that are non-pollutant.
