For some decades, special scientific and technological attention has focused on the possibility of recycling waste material that has been deposited into the environment as a consequence of industrial activity, mining operations of both natural stone and metal extraction, as well as from the use of mineral residues in the restoration of natural environments. Several authors have shown that with a suitable composition design, vitrifying or sintering many of these residues is possible, not only for reducing their volume, but what is more interesting from an economic point of view, for producing a wide range of vitreous and/or ceramic materials that can have industrial applications, fundamentally in construction (building and public works). The Iberian Peninsula has several industrial clusters, such as the natural stone sector of Novelda (Alicante), wherein rock waste residues rich in calcium from the exploitation of Mesozoic limestones are deposited. In nearby urban areas, sludge residues from wastewater treatment plants (WWTP) result in the form of sewage sludge that are very common throughout the territory. Furthermore, thermoelectric and metallurgic type industries that are scattered widely around the peninsula produce a large variety of waste in the form of slags, sludges, and powders. One of these wastes with a high manganese oxide content has been found and characterized in a deposit on a beach along the Galician coast of Spain. Lastly, this research also considered a waste rich in hexavalent chromium, which for some time has been known to be toxic, from the Latino-American country of Mexico. The presence of lithium in pegmatite exploitations along the Spanish and Portuguese border also produce waste mining steriles containing this element that could be applicated in the manufacture of glazes or enamels and materials of the glass-ceramic materials. At the same time and in the Valencian Community, which is still agricultural in many areas, the presence of industry plays a prominent role due to the ceramic cluster of Castellón, whose flooring and coating industries can provide knowledge about the type of process commonly used (sintering or vitrification), not only for the inertization of these types of wastes, but also for their use as a secondary raw material. Because of this, research in this thesis has been conducted on the above mentioned industrial wastes to learn the conditions under which they can be inertized or used in the composition of traditional materials as a secondary raw material and additionally in the production of new material products mainly for agriculture and construction applications.
