“…Because the consumption habits of the population have generated environmental problems such as the growth of landfills and depletion of natural resources [1,2], scientific research has been much requested regarding the recycling of discarded materials, for finding new utilities and generating value from the waste [2][3][4][5]. Glass, despite being recyclable, occupies large volumes in landfills [6].…”

In this work, glass-ceramics were produced with mechanical and physical properties, using recycled glass powder from windshields as raw material. The glass powder was formed and sintered at temperatures 600, 650, 700, 750, and 800°C. Pieces were also produced with the addition of niobium oxide to the glass powder. The flexural strength and the Archimedes density of the produced parts were determined. The reliability of the results was evaluated by the Weibull statistic. X-ray diffraction was performed. Maximum flexural strength was 77.64 MPa at 750°C, with the addition of niobium oxide at 43.86 MPa at 700°C. X-ray diffraction showed crystalline structures in the specimens with the addition of the nucleating agent, confirming the production of glass-ceramics in this composition. The pure glass powder only crystallized from 750°C. The Nb2O5 favors the formation of crystalline structures in the vitreous matrix at low temperatures and with piezoelectric structures.

“…Technological performance indicators are shown in Table 6, namely, dimensional conformity, which is measured by comparing the effective length with the nominal length (ISO 10545-2) (the measurements were performed with CNE100 1000 mm fiftiethsimal caliper, ±0.02); water absorption conformity which is measured under vacuum according to ISO 10545-3 [86] (the measurements were performed with Bel Engineering M6202Di Model Precision balance, ±0.01 g); and flexural strength according to ISO 10545-4 [87] (the measurements were performed with Gabbrielli Technology Flexi 1000 LX-650, ±100 g). Linear shrinkage of fired tiles was determined as the difference between the length of unfired and fired samples [88].…”

The digital transformation of manufacturing firms, in addition to making operations more efficient, offers important opportunities both to promote the transition to a circular economy and to experiment with new techniques for designing smarter and greener products. This study integrates Industry 4.0 technologies, smart data, Life Cycle Assessment methodology, and material microstructural analysis techniques to develop and apply a circular eco-design model that has been implemented in the Italian ceramic tile manufacturing industry. The model has been initially adopted in a simulation environment to define five different scenarios of raw material supply, alternative to the current production one. The scenarios were then validated operationally at laboratory scale and in a pilot environment, demonstrating that a proper selection of raw material transport systems significantly improves the environmental performance of the ceramic product. Both the results of the laboratory tests and of the pre-industrial experiments have demonstrated the technological feasibility of the solutions identified with circular eco-design, enabling the re-engineering of the ceramic product as the fifth of the 6Rs of the circular economy.

O crescimento dos impactos ambientais ocasionado pelos resíduos descartados no meio ambiente desperta grande interesse entre os pesquisadores, a fim de buscar soluções. Os custos de disposição de resíduos de forma ecologicamente correta são muito elevados, o que tem motivado a busca por alternativas tecnológicas viáveis para a reutilização de resíduos industriais, tanto na reintrodução dos ciclos industriais já existentes, quanto na produção de novos produtos, os quais podem assumir lugares de destaque em vários segmentos, sendo um dos mais importantes e principais, a indústria da construção civil. Este trabalho tem por objetivo caracterizar e combinar matérias-primas alternativas, como resíduos advindos de ciclos industriais para obtenção de cerâmica de revestimento que atenda as exigências da norma ABNT NBR ISO 10545-2:2020, a qual fixa as características exigíveis para esse tipo de material. Os resíduos foram caracterizados por técnicas de análise química, mineralógica, térmica e granulométrica. Formulações cerâmicas contendo resíduos de caulim, granito e polimento do porcelanato foram produzidas por prensagem e sinterizadas em três diferentes temperaturas. As amostras sinterizadas foram caracterizadas por ensaios de absorção de água, perda ao fogo, retração linear de queima e tensão de ruptura à flexão. Os resultados indicaram que o resíduo do caulim é constituído por caulinita, mica e quartzo. O resíduo de granito é constituído por quartzo, mica, anortita e magnesiorblenda. O resíduo do polimento de porcelanato é constituído por mulita, quartzo e carbeto de silício. Os resíduos apresentam distribuições granulométricas significativamente diferentes. A análise das propriedades tecnológicas, as quais as diferentes combinações de resíduos foram submetidas, demonstra que os produtos obtidos se adequam as exigências da norma NBR 6502/1995 e podem ser classificados como revestimentos cerâmicos semiporoso e poroso.
