Human activity has led to a high degree of industrialization, which hasdrastically increased in the last decades. Industrial growth has meant morewaste generation and, at the same time, a negative environmental impact. Consequently,the need of searching for novel processes related to waste minimization andreuse arises, as is reflected in the increasing number of research worksrelated to the reuse of industrial wastes in recent years. The present surveydeals with the general evolution of the preparative methodologies employed forthe recycling of aluminosiliceous wastes, particularly by hydrothermalzeolitilization. The study focuses on the reutilization of two distinctiveindustrial residues: the discarded catalysts coming from the cracking unitiesused in the oil industry and the fly ashes generated in coal energy production.Both materials are high volume wastes produced by the industrial energy sector.Their use as a negative-cost raw material in the synthesis processes ofzeolite-containing microporous materials and their potential applications asadsorbents in environmental remediation technologies will be emphasized.
