“…The incorporation of 2% (w/w) sludge from the poultry slaughterhouse wastewater treatment system in the ceramic mass for the production of tiles did not significantly alter the properties of the material, being even possible to reduce the consumption of fuel in burning [21]; a similar results was showed by [22], who estimated that an energy saving of 15-47% could potentially be achieved during firing with 10-40% tannery sludge-amended bricks chrome-rich, also obtaining, an increase of the compressive strength and water absorption, of 170% and 190%, respectively. Contrary to these results, [23] reported that increasing the paper sludge content in the clay mixture for structural bricks production decreases its mechanical strength, even though provides the material with improved properties regarding its thermal and acoustic insulation.…”

The sludge generated from water treatment has been classified as a potential environmental pollutant. Because of its chemical composition similar to clay, was proposed to evaluate the effect of its incorporation as a partial substitute for traditional clay materials in the manufacture of aluminosilicate refractory bricks. The raw materials used were characterized by XRD and XRF; the prototypes designed were mixed, extruded, dried and firing at 1200°C, evaluating their linear shrinkage, apparent density, porosity, water absorption and mechanical and pyroscopic resistance (melting cone softening point). The results show the addition of 10% of sludges from industrial water treatment plant, contributedto elevate the softening point the clay that obtaining a refractory brick capable to supporting a temperature up to 1430 °C

“…The firing temperatures used were defined through the evaluation of other bibliographic works that studied the application of clay masses for application in red ceramics used in civil construction. As an example, the work of Yang et al (2009) 29 who burned the ceramic masses at temperatures up to 1000°C; Wang et al (2020), 30 who highlight that the Chinese industry burns ceramic pieces at temperatures between 800 and 1000°C; Faria et al (2019) 31 performed the burning of the ceramic pieces at temperatures between 850 and 950°C; Ferreira et al (2018) 32 also carried out the burning of ceramic pieces at temperatures up to a maximum of 1000°C. Although the firing values seem low when compared with other ceramic applications, such as in electronic circuits, aerospace, and petrochemical industry, the values are consistent for the application of ceramics in the construction sector.…”

As a result of the economic crisis faced in Brazil, industries in the red ceramic sector have economic problems. The objective of this work was to evaluate, technologically and economically, through analysis of economy, the implementation of the production of ceramic tiles, a material with higher added value than bricks and ceramic blocks, in a ceramic industry located in the state of Rio de Janeiro, Brazil. The ceramic tiles were produced containing the incorporation of ornamental rock waste (ORW). The state has a region that has a red ceramic pole, but produces only products with lower added value. For this, specimens were produced with four different ceramic masses burned at temperatures in the range of 800 to 1050°C. Three masses were produced with different clays from the region (ceramic mass 1, 2 and 3) and a ceramic mass 4 was evaluated containing the clay that presented the best results and with the inclusion of sand and ORW, aiming at the analysis of economy. It was found that the masses containing only clays showed satisfactory parameters of resistance, but showed deficiencies in water absorption. The fourth mass, however, presented acceptable values in all the evaluated properties and was chosen to carry out a full‐scale industrial test, which enabled the development of economic analysis and an economic analysis using the theory of real options. The results obtained in this last stage were also positive, providing an internal rate of return of 16.82%, above the minimum practiced rate of 15%, proving the efficiency of the economy applied to the manufacture of extruded tiles in the industries of the study region.
