In a groundbreaking study published in ‘MATEC Web of Conferences’, researchers have turned their attention to the potential of agro-food waste as a sustainable additive in construction materials. Led by Fernandez Federica from the Dipartimento di Architettura Università degli Studi di Palermo, the research evaluates the use of pistachio shells and orange peels in gypsum-based plasters, aiming to create lightweight mortars that adhere to green building principles and contribute to a circular economy.
As the construction industry increasingly seeks sustainable alternatives, this research highlights the promising properties of bio-based mortars. These materials not only exhibit high porosity and reduced weight but also demonstrate excellent thermal insulation and sound absorption capabilities. “Our findings indicate that these bio-based mortars can perform on par with, or even surpass, traditional plasters,” Fernandez noted, emphasizing the commercial viability of such innovations.
The study is particularly relevant in the context of Mediterranean countries like Sicily and Tunisia, where the abundance of agricultural by-products presents a unique opportunity for resource utilization. The project, part of a strategic cross-border cooperation initiative known as CUBÂTI, aims to foster collaboration in research and innovation for sustainable building practices. “By utilizing materials that are readily available in our regions, we not only address waste management but also enhance local economies,” Fernandez added, underscoring the dual benefits of this approach.
Through a series of rigorous tests, the researchers optimized the mix design of the plasters, revealing significant improvements in mechanical resistance, thermal conductivity, and reduced water absorption. This not only suggests a shift towards more eco-friendly construction materials but also opens avenues for cost-effective solutions in building projects.
As the construction sector grapples with the need for sustainability amid growing environmental concerns, this research could serve as a catalyst for future developments. The integration of agro-food waste into building materials may not only reduce reliance on conventional resources but also promote innovative practices that align with global sustainability goals. The findings from this study are likely to inspire further exploration into the use of natural additives in construction, paving the way for a greener, more sustainable future in the industry.
