Roof tiles made from coal ash and glass waste cut carbon emissions by 13%
AI Article Summary

RMIT University and Bristile Roofing have collaborated on a large-scale trial to produce roof tiles made of coal ash and recycled glass, reducing carbon emissions by 13%. These tiles, manufactured in Melbourne, are lighter, more fire-resistant, and meet Australian standards for durability. The project demonstrates that industrial waste can be used without compromising product quality. Additionally, the same mix of waste materials is being used to create eco-friendly bricks with significant reductions in CO₂ emissions.

What This Means for Canadian Contractors

This project shows how innovative use of waste materials can significantly reduce carbon footprints for construction products. For Canadian builders, this means there might be opportunities to adopt similar sustainable practices, potentially impacting project costs and timelines positively. The development could stimulate interest in using local waste resources, improving material supply chains and sustainability initiatives.
