“…CFA is also used as an adsorbent for the removal of pollutants—mainly dyes [ 57 , 58 ], pesticides [ 57 , 58 ], and heavy metals [ 59 , 60 ]—from wastewater. It is used for making nanocomposites [ 61 ] that are applicable in the defense industry [ 62 , 63 ] and the production of lightweight materials [ 64 , 65 ]. CFA can be used for making blended cement [ 66 ] tiles, bricks [ 67 ], blocks [ 56 ], RCC, kitchen panels, and geo-polymers.…”

Environmental pollution is one of the major concerns throughout the world. The rise of industrialization has increased the generation of waste materials, causing environmental degradation and threat to the health of living beings. To overcome this problem and effectively handle waste materials, proper management skills are required. Waste as a whole is not only waste, but it also holds various valuable materials that can be used again. Such useful materials or elements need to be segregated and recovered using sustainable recovery methods. Agricultural waste, industrial waste, and household waste have the potential to generate different value-added products. More specifically, the industrial waste like fly ash, gypsum waste, and red mud can be used for the recovery of alumina, silica, and zeolites. While agricultural waste like rice husks, sugarcane bagasse, and coconut shells can be used for recovery of silica, calcium, and carbon materials. In addition, domestic waste like incense stick ash and eggshell waste that is rich in calcium can be used for the recovery of calcium-related products. In agricultural, industrial, and domestic sectors, several raw materials are used; therefore, it is of high economic interest to recover valuable minerals and to process them and convert them into merchandisable products. This will not only decrease environmental pollution, it will also provide an environmentally friendly and cost-effective approach for materials synthesis. These value-added materials can be used for medicine, cosmetics, electronics, catalysis, and environmental cleanup.

Waste materials from the automotive industries were re-used as aggregates into metakaolin-based geopolymer (GP), geopolymer mortar (GM), and Bauhaus B20-based concrete composite (C). Specifically, the study evaluates the ability of windshield silica glass (W), PVB-Foils (P), and rubber granulates (G) to impact the mechanical and thermal properties. The addition of the recovered materials into the experimental geopolymers outperformed the commercially available B20. The flexural strength reached values of 7.37 ± 0.51 MPa in concrete with silica glass, 4.06 ± 0.32 in geopolymer malt with PVB-Foils, and 6.99 ± 0.82 MPa in pure geopolymer with rubber granulates; whereas the highest compressive strengths (бc) were obtained by the addition of PVB-Foils in pure geopolymer, geopolymer malt, and concrete (43.16 ± 0.31 MPa, 46.22 ± 2.06 MPa, and 27.24 ± 1.28 MPa, respectively). As well PVB-Foils were able to increase the impact strength (бi) at 5.15 ± 0.28 J/cm2 in pure geopolymer, 5.48 ± 0.41 J/cm2 in geopolymer malt, and 3.19 ± 0.14 J/cm2 in concrete, furnishing a significant improvement over the reference materials. Moreover, a correlation between density and thermal conductivity (λ) was also obtained to provide the suitability of these materials in applications such as insulation or energy storage. These findings serve as a basis for further research on the use of waste materials in the creation of new, environmentally friendly composites.

“…One possible solution [4][5][6][7][8] includes manufacturing alumina silicate-based lightweight aggregates (LWA) that can be used in both building and gardening industries. Another constituent balancing the chemical composition of the ceramic batch includes other waste material from the coal/ore industry, especially coal mine slates or any other alumina silicate-based waste material [8][9][10][11][12][13]. Fabricated aggregates could be applied to concrete block production; however, a number of requirements, specified in EN 1097, UNE-EN 13055 and many other standards must be fulfilled for this purpose [14,15].…”

“…The manufacturing of LWA from the alumina silica slates and glass powder mixture requires the addition of the poreforming agent for preventing significant sintering and densification during thermal treatment. The presence of some PVB in the mixture of waste materials may be beneficial since PVB may increase porosity of the resultant granules due to a CO/CO 2 gas evolution during thermal decomposition of PVB as well as the ability of glass powder to form bubbles through the viscosity reduction [8,13]. It is worth mentioning that a large calorific value of PVB (20,000 kJ/ mol) would be valuable for the granule manufacturing economy.…”

This paper presents mechanical and physical properties of light porous aggregates obtained from local waste materials. Granules were produced from a mixture of aluminosilicate-based coalmine slates and car windshield glass that was contaminated by the polyvinyl butyral foil. The initial waste material ratio modification significantly alters physical and mechanical properties of obtained ceramic granules to the extent of the critical amount of added windshield glass powder. The temperature of the heat treatment affects the granules' properties and demonstrates the microstructure and phase crystallization control possibilities. The critical value of the windshield glass concentration was determined to be at a level of 30%, considering the relationship between mechanical and physical properties when large porosity is essential in further application. On the other hand, if the glass-to-slates weight ratio was equal and a sufficient thermal treatment was applied, a core-shell macrostructure formation and occlusion of pores occurred.
