What was once considered a challenging industrial waste product could become part of the solution to one of construction's biggest sustainability challenges.
Researchers from Trinity College Dublin, working alongside industry partners Gannon Eco and McGrath Quarries, have developed innovative concrete formulations using bauxite refining residue ("red mud"). Early industrial trials are showing promising results, with significant carbon reductions and performance levels that match or exceed traditional concrete in demanding conditions.
As the construction industry seeks practical pathways to lower emissions, projects like this demonstrate how waste materials can be transformed into valuable resources.
