“…Extractive waste recovery and recycling have been investigated in several studies (scientific papers, founded projects, etc.) [55][56][57][58]. Waste rocks, operating residues, and tailings, if managed separately, and depending on the specific characteristics of the ore deposits and/or the processing and working activities, can be considered as "mono-waste" landfill and properly exploitable for RM/CRM/SRM production.…”

Extractive waste (EW), including tailings, is produced in large quantities during mining activities. In recent years, the linear economic model (“take-use-and-throw” approach) has been replaced by a circular approach, emphasizing the sustainable use and recovery of EW. The development of innovative protocols, such as Best Available Techniques (BATs), which aim at the technological and process improvement of more sustainable mining activities and at the production of renewable, highly performing green materials, has led to technological advancements, expertise in sustainability, and a reduced ecological footprint, potentially causing positive economic and social impacts and reducing environmental ones. Extractive waste and tailings, if suitably characterized, can be used to improve and make sustainable the works connected to the management of mining activities. The qualitative–quantitative characterization of EW is essential for subsequent reuse and for assessing the risk to human health and the extent of environmental impacts in the various matrices. The application areas vary according to the type of waste and mining tailings, the morphological characteristics of the deposits, and the geological, geomorphological, and logistic context of the area. Integrated protocols for sustainable EW exploitation and positive impacts on the economic, environmental, and technological/social level are analyzed. The present paper aims at providing an overview of challenges and potentialities connected to extractive waste (EW) management and potential exploitation to recover raw materials (RM), critical raw materials (CRM), and secondary raw materials (SRM).

“…The waste was mixed into the ceramic pastes at varying weights. Specimens were then manufactured through extrusion and fired at temperatures of 1050 • C and 1100 • C. The results showed improved properties in the ceramics with the inclusion of waste at both temperatures [11].…”

This paper discusses the historical use of natural stone for various purposes and highlights the substantial waste generated by quarries and stone processing plants in modern industrialized production. These waste materials are typically categorized into unused rock and sludges from processing. This accumulation of waste presents a global environmental challenge and a financial burden for the stone industry. In-depth investigation into the development of a binder incorporating carbonated sludge from marble and limestone industries, combined with polyester resin, for building stone composites was performed. This research involved chemical and microstructural characterization of the sludges, preparation of mixtures with polyester resin, stone composites manufacturing, and subsequent testing to determine and validate the optimal binder composition. Given the achieved results, and the demonstrated feasibility of using a binder composed of polyester resin and carbonated sludge for stone composite production, it was concluded that employing carbonated sludge as an economic resource is indeed viable.

“…The granulometry of the granite waste benefited by multiwire gangsaw was also carried out. The results showed that the waste is a non-plastic material and that its fine particles contribute to better packaging and to the improvement of the final ceramic product [18].…”

“…However, with the replacement of 40% and 50% it starts to decrease, but with superior resistance in ceramics fabricated only with clay. Another factor that must have significantly influenced this decrease was quartz, a mineral that composes the waste, which probably acted as an inert material and may have contributed to the formation of microcracks [18]. The flexural strength of ceramics is greatly influenced by the presence and shape of defects in their microstructures, such as grains and pores [28].…”

The ornamental stone industry is growing and has a large production in Brazil, mainly in Espírito Santo, where the largest production in the country is concentrated. Brazil is part of the group of countries that produce the most ornamental stones in the world; however, the generation of waste in this sector is very large. These ornamental stone wastes when used for the manufacture of new materials, such as red ceramics, contribute to the reduction in the raw material clay and to the reduction in the environmental impact. The objective of this work was to incorporate fine wastes from the processing of ornamental stones called FIBRO in red ceramics and later, to contribute to the standardization of the use of these wastes in the ceramic industry, contributing to the manufacture of more economical and sustainable products. Wastes were incorporated in the proportion of 0 to 50% by mass that were prepared by extrusion and fired at 900 °C, 950 °C, and 1000 °C. After firing, the physical and mechanical properties of the ceramic material were evaluated. Specific mass apparent, water absorption, porosity, and flexural strength by three points tests were carried out. The results showed that from 30% at the lowest temperature, tile is already fabricated within the values stipulated by the standards, thus saving energy. The analyzed waste is a material with excellent chemical characteristics to be used in the ceramic mass, in addition to having improved the technological properties of the material, such as less water absorption and greater flexural strength.
