Waste materials tested to create stronger, low-carbon cement products
A James Dyson Award project is exploring the use of recycled waste materials including eggshells and glass to manufacture sustainable cement building products. The initiative aims to reduce environmental impact while producing thinner, stronger construction materials.

Researchers have begun testing 17 different waste materials as potential components in cement-based construction products, marking a significant step toward more sustainable building practices. The project incorporates recycled aggregates such as eggshells, glass, and other industrial byproducts to replace conventional raw materials traditionally used in cement manufacturing.
The approach addresses a critical environmental concern: the heavy reliance on newly extracted natural resources in the construction sector. By redirecting waste streams into building applications, the initiative reduces demand for virgin materials while simultaneously lowering the carbon footprint associated with cement production and material extraction.
Engineers involved in the project are focusing on developing cement boards and tiles that are both thinner and more durable than conventional alternatives. The use of recycled aggregates allows for improved material properties while maintaining structural integrity, potentially reshaping how the industry approaches resource utilization.
Ongoing testing will evaluate the long-term durability of these innovative products and assess their viability for future recycling. Researchers are examining whether the waste-based cement materials can be reclaimed and reprocessed at the end of their service life, creating a more circular economic model for the construction industry. Results from these assessments will be critical in determining whether the technology can be scaled for broader commercial application.
