R2Crete, a University of Melbourne spinout pioneering a breakthrough concrete recycling technology, has secured $750,000 in pre‑seed funding from Uniseed and the University of Melbourne Genesis Pre-Seed Fund.
Concrete is the world’s most widely used construction material and accounts for an estimated 7-8 per cent of global carbon emissions, a footprint expected to grow in the coming decades. In Australia alone, an estimated 7 million tonnes of waste concrete is generated each year – a figure that could exceed 2 billion tonnes globally.
R2Crete’s patented process transforms waste concrete into high‑value clean aggregates and a cement replacement that can be reused in new concrete production, significantly reducing carbon emissions, landfill waste, and the demand for raw materials such as sand, gravel and limestone.
The technology, which is based on research developed by Dr Tuan Nguyen, Senior Lecturer in the Faculty of Engineering and Information Technology, can recover up to 75 per cent of the cement in waste concrete, delivering a 50 per cent reduction in CO2 emissions while retaining the performance characteristics of traditional concrete.
The current raise marks a major milestone in the company’s commercialisation journey and will support the construction of R2Crete’s pilot commercial plant – enabling validation of the technology at commercial scale, supply of material for industry trials, and acceleration of industry partnerships.
Jeffrey Bourne, Investment Manager at Uniseed, highlighted the technology's scalability and commercial potential.
“The R2Crete process stands out for its ability to produce high-quality recycled and low-carbon materials suitable for concrete production in a cost-effective and efficient manner. We believe R2Crete is well-positioned to become a leader in sustainable construction materials, and we’re proud to back their journey from research to commercial reality.
Warren Overton, Managing Director of R2Crete, said the investment represents a strong vote of confidence in the company’s technology and mission.
“Securing this funding from Uniseed and Genesis is a pivotal moment for R2Crete. It enables us to move from laboratory success to real‑world commercial deployment. Our pilot plant will demonstrate that high‑value recycled aggregates and cement replacement products can be produced reliably, cost effectively, and at scale – helping the construction industry transition to a more circular and lower carbon future.”
