Graphene-enhanced concrete showcased at Toronto’s Exhibition Place

Bio Graphene Solutions (BGS) has completed the second public demonstration of its graphene-enhanced low-carbon concrete in partnership with Exhibition Place in Toronto. The commercial pour, showcased beneath the city’s landmark Princes’ Gates, marks another step forward in the practical deployment of advanced nanomaterial technologies for sustainable construction.

The patent-pending admixture developed by BGS enables up to a 25% reduction in cement use, cutting embodied carbon by 275–500kg CO₂e per truckload while maintaining strength and durability comparable to standard concrete mixes. The demonstration forms part of Exhibition Place’s wider GREENSmart environmental initiative, which has already reduced its carbon footprint by 34% between 2019 and 2024.

Don Boyle, chief executive of Exhibition Place, said: “Exhibition Place is proud to be a leader in advancing sustainability within Toronto’s built environment. Partnering with BGS allows us to test and showcase innovative technologies that reduce greenhouse gas emissions and support our long-term vision of a greener, more sustainable future for our city.”

The collaboration highlights the potential of graphene admixtures to decarbonise one of the world’s most carbon-intensive materials. With concrete production responsible for around 8% of global CO₂ emissions, solutions that reduce cement content without compromising performance are critical to achieving net-zero construction goals.

David Fisher, chief executive of Bio Graphene Solutions, said: “Our mission is to revolutionise construction materials with sustainable innovation. This collaboration with Exhibition Place demonstrates the real-world benefits of graphene-enhanced low-carbon concrete and reinforces our commitment to Canada’s net-zero future.”

Initial test results from earlier trials have already shown measurable improvements in strength and durability. Further Day-28 testing is now underway to validate the long-term performance of the graphene-modified concrete, which could play a key role in future municipal and infrastructure applications.

The demonstration underscores the growing convergence of nanotechnology and concrete innovation, an area attracting significant global attention. For UK and European readers, graphene-based admixtures represent a parallel development to ongoing low-carbon cement initiatives and carbon-capture concretes, providing valuable insights into how advanced additives can reduce embodied carbon at scale.
