摘要

This study proposes a sustainable approach to transform solid waste into innovative and eco-friendly construction materials. Recycled textile fibers and expanded polystyrene, dissolved in natural D-limonene, were used to fabricate thermal and acoustic insulation panels as well as eco-tiles. Selected formulations were reinforced with aluminum powder to enhance their mechanical performance. Mechanical testing revealed compressive strength of 286.35 kN, tensile strength of 0.983 MPa, and elongation of 1.80% for the eco-tiles, while the insulation panels exhibited 174.51 kN, 0.599 MPa, and 2.39%, respectively, confirming their suitability for sustainable building applications. In parallel, a natural wall paint was developed using treated cow dung as a bio-based precursor, combined with gum arabic, titanium dioxide (TiO₂), calcium oxide (CaO), hydroxyethyl cellulose (HEC), and sodium benzoate without any toxic solvents. Carboxymethyl cellulose (CMC) was extracted from cow dung using sodium hydroxide (NaOH) and hydrogen peroxide (H₂O₂), and its formation was confirmed by Fourier Transform Infrared Spectroscopy (FTIR) analysis. The paint exhibited strong antibacterial activity against Escherichia coli and Staphylococcus aureus, highlighting its potential for hygienic and health-sensitive environments. These dual innovations support the Sustainable Development Goals (SDGs), particularly Responsible Consumption and Production, Industry, Innovation and Infrastructure, and Sustainable Cities, by offering safe, circular, and sustainable alternatives to conventional materials and paints.
