Considering current climate challenges and the search for more sustainable alternatives, this study investigates the technical and environmental feasibility of using glass powder from post-consumer bottles as a partial replacement for Portland cement in the production of tactile hydraulic tiles. For this purpose, CP-V ARI cement, natural sand, and finely ground glass powder—collected from a public institution in the state of Alagoas equipped with glass packaging crushing equipment—were used. The raw materials were characterized through particle size analysis, Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS), X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TG), and pozzolanic activity tests. The results indicated that the by-product presents angular and irregular particles, a high silica content (69.63% SiO2), and thermal stability. The experimental program involved the production of prismatic test specimens with different glass powder replacement levels: 0%, 6%, 12%, and 18%. The samples were subjected to water absorption by immersion, compressive strength, and flexural tensile strength tests. Statistical analyses included ANOVA, polynomial regression, and Pearson correlation. The results showed no significant difference in water absorption among the formulations, indicating that the composite’s porosity was maintained. The compressive strength performance was optimal at 7.20% substitution, reaching 47.39 MPa, while flexural tensile strength decreased as the glass powder content increased. The formulation with 7.20% glass powder was selected for tile production, meeting the mechanical strength requirements defined by NBR 9457 (ABNT, 2013). The final tile also met dimensional specifications in terms of width, height, and length. The findings demonstrate that incorporating glass powder is a technically viable and environmentally relevant solution for producing hydraulic tiles. This proposal aligns with the United Nations Sustainable Development Goals (SDGs), promoting sustainable practices in the construction sector and encouraging the use of secondary raw materials in accordance with circular economy principles.ptSustentabilidadeEconomia circularSubprodutosLadrilhos hidráulicosDissertaçãoOUTROS
