Spent Cigarette Butts May Find Use In Longer-Lasting Roads
Researchers from the University of Granada and University of Bologna, with support from China, have developed a method to recycle used e-cigarette butts into asphalt for roads. After removing ash, the cellulose and PLA fibers from filters were shredded, bound with synthetic wax, and formed into pellets. Mixed with recycled asphalt and bitumen, this material created a new asphalt that was 40% butt pellets and recycled road material. The enhanced asphalt showed greater strength, flexibility, fatigue resistance, and lower production temperatures, making it more durable and energy-efficient while addressing cigarette waste pollution.
