Researchers at Isfahan University of Technology have made a breakthrough in sustainable construction materials by incorporating modified carpet waste into concrete, significantly enhancing its physical and mechanical properties. Supported by the Research and Technology Fund of the Vice Presidency for Science and Technology, this project introduces a cost-effective and eco-friendly alternative to conventional fillers in polymer and cement concretes.
Carpet waste, which is abundant and underutilized, is used as a lightweight filler, reducing overall product weight while improving structural integrity. This approach addresses one of the major economic hurdles in producing polymer concrete—the high cost of resins—by replacing part of the resin content with dispersed polymer waste. The resulting concrete is not only stronger but also lighter, making it ideal for building applications that demand both durability and reduced weight.
This innovation not only contributes to waste recycling and circular economy efforts but also paves the way for future use of textile waste in other industrial sectors. The research team believes this method could be scaled for widespread use in infrastructure projects, promoting both economic and environmental sustainability in construction.
