| Abstract Scope |
Utilizing recycled materials in additive manufacturing offers a solution for repurposing glass waste, addressing significant environmental concerns. This investigation explores using waste glass bottles for manufacturing bricks via Direct Ink Writing (DIW). Bricks with unique geometries were produced from yellow clay in Campos dos Goytacazes, Brazil, with 30% glass waste powder. To reduce water content, 3 wt% of citric acid, 1 wt% cornstarch, and 0.2 wt% sodium silicate were evaluated. Tests for density, shrinkage for length, width, and height, assessed the material’s properties. Raw materials were characterized using x-ray fluorescence (FRX). Compression strength analysis was conducted to understand mechanical properties and sample variability. Additionally, a scanning electron microscopy (SEM) test was used to analyze the microstructure of the raw materials and manufactured samples. The integration of glass residue in the production of ceramic pieces through additive manufacturing not only enhances the properties and performance of the final products but also represents a sustainable approach by minimizing environmental waste. |
