Cigarette butts create a massive and messy environmental burden. According to their findings, published in the journal Construction and Building Materials, cigarette filters can substantially strengthen recycled asphalt ahead of its reapplication onto roads. The materials in cigarette filters act as strengthening and bonding agents in recycled asphalt. Pellet 1 contained only cigarette butts, while Pellet 2 featured the cigarette material and an additional recycling agent. Once melted, the recycled cigarette butts’ plastic fibers and cellulose integrate into the material and reinforce it by improving both its flexibility and resistance to cracking.
