Spanish and Italian scientists design sustainable and more resistant asphalt using cigarette butts
Researchers from the Building Engineering Laboratory (LabIC.UGR) are collaborating with the University of Bologna (Italy) on the design and evaluation of the resistance of asphalt made from pellets of this waste, in a project co-funded by the Chinese government. Since the advent of filter cigarettes, cigarette butts have become a predominant form of waste, with projections indicating that around 9 trillion will be generated worldwide in 2025. This poses a serious environmental problem, as many of them are improperly disposed of in natural environments, beaches, forests, waterways, etc.
