A sustainable concrete alternative made with slate waste

SlateRete: Revolutionizing Construction with Slate Waste

In a groundbreaking leap for sustainable construction, SlateRete, a NovaUCD-based startup founded in 2024, is turning heads with its innovative approach to replacing traditional concrete. By transforming slate waste into a high-performance, eco-friendly construction material, SlateRete is not just addressing the environmental impact of concrete but also redefining the aesthetics of modern infrastructure.

Concrete, a material that has been a cornerstone of construction since Ancient Greece and Rome, is now under scrutiny for its significant environmental footprint. Responsible for 4-8% of global CO2 emissions, the production of concrete has long been a thorn in the side of sustainability efforts. Enter SlateRete, co-founded by Hamed Panahiazar and his brother Sadegh, who are on a mission to revolutionize the construction industry.

The Science Behind SlateRete

SlateRete’s innovative solution involves replacing high-carbon concrete ingredients with slate waste, reducing CO2 emissions by more than 40%. This not only eliminates the need for pigments but also minimizes the extraction of virgin materials. The startup’s product is engineered to meet three key areas of innovation: environmental impact, materials science, and design.

Hamed Panahiazar, a senior project manager with over a decade of experience in the construction industry, explains, “Unlike conventional concrete, which relies on high-carbon-footprint materials like cement, sand, limestone, and granite, SlateRete repurposes slate waste, reducing environmental impact while maintaining structural integrity.”

The SlateRete mix, developed through extensive laboratory research at University College Dublin (UCD), replaces 75% or more of traditional concrete components with slate waste. This optimization ensures workability, strength, and durability, achieving a compressive strength of C25/30 and exceptional freeze-thaw resistance.

Aesthetics Meets Sustainability

One of the standout features of SlateRete is its natural coloration. Unlike conventional concrete, which relies on chemical additives for coloration, SlateRete’s colors—blue, green, grey, ochre, purple, and black—arise naturally from the mineral composition of slate. This not only eliminates the use of synthetic dyes but also enhances the material’s aesthetic appeal.

Overcoming Challenges

SlateRete’s journey hasn’t been without its hurdles. Balancing technical validation with strategic fundraising and market readiness has been a significant challenge. Hamed Panahiazar notes, “Developing a deep-tech, materials-based innovation requires significant certification, testing, and regulatory alignment, all while positioning the brand for investment.”

Despite these challenges, SlateRete has successfully undergone over 20 mix trials and extensive laboratory characterization at UCD, leading to a validated prototype. The startup is now focused on preparing for investment rounds and building relationships with industry stakeholders in Europe and the Gulf Cooperation Council (GCC) regions.

The Future of Construction

SlateRete’s vision is clear: to transform the global construction materials industry by replacing environmentally damaging concrete products with a sustainable, waste-made, high-value alternative. As the world grapples with the urgent need for sustainable solutions, SlateRete stands at the forefront of innovation, proving that sustainability and performance can go hand in hand.
