In the quest for sustainable and fire-resistant construction materials, a team of researchers led by G M Faysal from the Department of Textile Engineering at Northern University Bangladesh and Dhaka University of Engineering and Technology has made a significant breakthrough. Their work, published in the journal *Materials Research Express* (which translates to *Materials Research Express* in English), introduces innovative bio-based composite ceiling panels that could revolutionize the construction industry.
The team developed five bio-based composite ceiling panels using recycled textile fibers and functional additives derived from everyday waste materials: eggshell powder, banana peel, spinach extract, green apple extract, and egg yolk. The researchers compared the effects of two binders, sodium silicate and polyvinyl acetate (commonly known as Fevicol), on the thermal stability and flame retardancy of these composites.
The results were promising. The composites with sodium silicate as the binder showed superior fire and structural performance compared to those with Fevicol. Notably, the best-performing composition—eggshell/cornstarch/recycled fiber with sodium silicate—had the highest degradation temperature of 515°C, the longest high-temperature deformation resistance time (t ≥ 900 seconds), and achieved complete non-ignition under flame action.
“This research highlights the potential of using low-cost, eco-friendly materials to create fire-resistant ceiling solutions,” said Faysal. “The use of waste materials not only reduces environmental impact but also offers economic viability, making it a win-win situation for both the industry and the planet.”
The implications for the construction and energy sectors are substantial. As buildings become more energy-efficient, the demand for sustainable and fire-resistant materials is on the rise. These bio-based composites could offer a cost-effective and environmentally friendly alternative to traditional materials, reducing the carbon footprint of construction projects.
Moreover, the use of recycled and waste materials aligns with the growing trend of circular economy principles in the construction industry. By repurposing materials that would otherwise end up in landfills, this research contributes to a more sustainable future.
“The simplicity of execution and economic viability of these composites make them an attractive option for large-scale applications,” added Faysal. “This could pave the way for more innovative and sustainable construction practices in the future.”
As the construction industry continues to evolve, the adoption of such bio-based materials could shape the future of building design and construction, offering a balance between performance, sustainability, and cost-effectiveness. This research not only advances the field of sustainable composites but also sets a precedent for future developments in eco-friendly construction materials.
