Researchers have shown how a blend of old tires and building rubble could be used as a sustainable road-making material, in a zero-waste solution to boost recycling and support the circular economy.
Construction, renovation and demolition account for about half the waste produced annually worldwide, while around 1 billion scrap tires are generated globally each year.
The new material, developed by researchers at RMIT University in Melbourne, Australia, is the first to combine recycled rubble and rubber in a mix that is precisely optimised to meet road engineering safety standards.
