Cigarette butts are the most littered item on Earth — 4.5 trillion of them every year. But scientists just found a way to turn them into something useful: stronger roads.
Researchers from Spain and Italy discovered that cigarette filters — especially from e-cigarettes — are packed with cellulose fibers. Those fibers make asphalt tougher, more flexible, and longer-lasting.
How it works:
Butts are collected and cleaned
Fibers are shredded and mixed with wax
The blend is pressed into pellets
Pellets are added to asphalt during road construction
The result? Roads that handle heavy traffic and temperature changes better than before. Plus, up to 40% of the final material comes from recycled waste.
One road built with this method is already in use in Bratislava, Slovakia.
Bottom line: Less litter. Stronger roads. A win-win. 🚬🛣️
