At RMIT University, engineers have revolutionized asphalt production by recycling discarded cigarette butts. These butts are safely encapsulated in bitumen or paraffin wax, making them suitable for road construction. Laboratory results indicate that this innovative mix can withstand diverse traffic loads while also lowering asphalt thermal conductivity, thus addressing urban heat challenges. Nevertheless, effective waste collection and thorough environmental assessments are crucial for the successful implementation of this sustainable solution.
