“…Serpentinites have been largely used as raw material for the production of ceramics. [23][24][25] Some of the studies address the use of serpentinite tailings from mineral processing. 22,23 The use of serpentinites in ceramics and civil construction ( Figure 7) is mainly due to its mechanical properties and also to its dark green color.…”

Serpentine is a versatile mineral family rich in Mg silicate with several polymorphic phases, mainly antigorite and lizardite, all of them with similar chemical composition (Mg 3 Si 2 O 5 (OH) 4 ). Their structures are generally composed of octahedral layers rich in Mg[MgO 2 (OH) 4 ] 6− , attached to a tetrahedral silicate [Si 2 O 5 ] 2− sheet. The unique physicochemical properties of serpentinites and the existence of large reserves in Brazil create new important opportunities for research and technological applications. In this work, serpentinites structures and properties are reviewed, as well as its occurrence and literature describing its applications in construction/ceramics, agriculture, as a silica source, in steel production, as an additive/filler in polymers, in the production of composites, adsorption of cations and organics contaminants, CO 2 capture and catalysis. The presence of harmful chrysotile associated with serpentinites, some of its properties and uses are also described.

“…Zhu et al (2012) [162] have prepared cordierite by solid-state reactions with three different types of raw materials, i.e., waste kaolin mine tailing as the source of SiO 2 and Al 2 O 3 , waste serpentine mine tailing as the source of SiO 2 and MgO, and alumina powder. Single-phase cordierite is achieved after sintering the pressed mixture mass at 1350°C for 3 h. Ramezani et al (2017) [163] and Zhou et al (2011) [164] have fabricated cordierite using waste serpentine and sepiolite (after heat treatment its transform into serpentine), respectively. Some studies also have found to investigate with RHA as an alternate of conventional silica sources for the preparation of cordierite [165][166][167].…”

Wastes from different manufacturing processes and energy generation unite are attributed to the ecological and health issues. Instead of land-filling, the waste can be recycled or reused to convert marketable value-added products with high ecologic and economic interest. Ceramics are attracting particularly in waste recycling perceptions. From this eco-friendly propensity, in the last two decades, an increasing number of studies have demonstrated the possibility to use alternative ingredients in the place of conventional raw materials (e.g., most common ternary clay-quartz-feldspar system) for the fabrication of ceramics. Researchers are trying to incorporate the wastes and industrial by-products like fly ash (FA), rice husk ash (RHA), blast furnace slag (BFS), sludge, glass waste, polished tile waste, eggshell and others for making different ceramics. The present review is aimed to provide an up-to-date overview of the recent wastederived ceramics including refractories, glasses, whitewares, oxide and non-oxide ceramics with the correlation of waste incorporation limits, manufacturing routes, and properties of the ceramics. The investigation reveals that ceramic industries have huge potential to utilize the wastes as substitution of the natural raw materials. The waste to value-added ceramics conversion not only solves the disposal problems but also conserves the natural resources.

“…In India, FCC spent catalysts are also known for being used as a refractory for furniture manufactured from a clay-based kiln. The particle size ranges from 60 to 100 µ m (Ramezani et al, 2017). The generation and untreated disposal of such fine particles causes major environmental concerns due to wide and uncontrolled dispersion of harmful metals present in the catalysts.…”

Industrial solid waste management encompasses a vital part of developed and developing countries strategies alike. It manages waste generated from vital industries and governs the hazardous waste generated as a major component of integrated waste management strategies. This article reviews the practices that govern the management approaches utilized in the developed world for industrial spent catalysts. It critically assesses the current situation of waste management within the developing world region focusing on the industrial waste component, in a novel attempt to crucially develop a strategy for a way forward based on best practices and future directions with major European industries. The review also draws parallels with European countries to compare their practices with those of the State of Kuwait, which rely solely on landfilling for the management of its industrial waste. Spent catalysts recovery methods are discussed at length covering conventional methods of valuable metals and chemicals recovery (e.g., hydrometallurgical, solid–liquid and liquid–liquid extraction) as well as biological recovery methods. A major gap exists within regulations that govern the practice of managing industrial waste in Kuwait, where it is essential to start regulating industries that generate spent catalysts in-view of encouraging the establishment of valorization industries for metal and chemical recovery. This will also create a sustainable practice within state borders, and can reduce the environmental impact of landfilling such waste in Kuwait.
