Special Issue Information

Dear Colleagues,

The increasing demand for sustainable materials is steering research towards the incorporation of waste in construction materials. Mortars and concrete have been extensively studied with the incorporation of different types of waste, such as industrial byproducts, agricultural residues, and post-consumer waste. However, several knowledge gaps still remain, and the performance, durability, economic, and environmental analyses of the composites must be deeply investigated. The energy balance of incorporating waste into new materials needs to be taken into account, as the main objective is to reduce the carbon footprint and contribute to a circular economy. Therefore, it is necessary to analyse all aspects involved in the development of the new material and to also consider waste characterization.

This Special Issue aims to address various topics related to the sustainable and innovative development of new materials through the incorporation of waste. We welcome research that investigates and applies different types of waste incorporation in sustainable materials. Additionally, studies on green technologies, which can be applied for sustainable development, are of significant interest. We highly appreciate literature reviews and state-of-the-art articles.

In Brazil, artificial lightweight aggregates (LWAs) are predominantly produced in the Southeast Region using clay as the primary raw material. However, clay extraction has significant environmental impacts and limits access to LWAs in the North and Northeast regions, resulting in high costs and hindering sustainable construction solutions. This study addresses these challenges by developing sustainable LWAs in the Northeast Region using raw materials from the metropolitan area of João Pessoa, Paraíba, namely chamotte (CHT), which is rich in aluminosilicates, and eucalyptus firewood ash (EFA), which is rich in carbonates, combined with kaolinitic clay (KC). Sixty-four binary mixtures were produced, demonstrating diverse properties in density, water absorption, and compressive strength. EFA-rich mixtures achieved the highest expansion (80%) and lowest density (1.20 g/cm3), while CHT-rich mixtures provided superior strength (>10 MPa) and deformation (>20 GPa). These properties highlight their suitability for diverse applications, from structural uses to landscaping, enhanced by distinct color variations. Statistical optimization identified the residue content and sintering temperature as key factors, confirming the technical viability of incorporating up to 80% industrial waste into sustainable LWA production. Therefore, the results confirm the technical feasibility of producing LWAs using CHT and EFA in the metropolitan region of João Pessoa/Paraíba, achieving properties comparable to commercial LWAs. By incorporating up to 80% industrial waste, this study reduces dependence on non-renewable resources, decreases CO2 emissions and transportation costs, and promotes sustainable practices. The findings offer a scalable, eco-friendly solution to resource-limited regions’ material scarcity. Full article
