Do cigarette butts biodegrade?



  1. 0 Votes

    More or less, no. Cigarette butts are considered to not be biodegradable. Cigarette butts typically contain plastic fibers (cellulose acetate) within the filter, so they can take quite a long time to degrade. Studies have shown cigarette butts taking anywhere from 18 months up to 10 years to degrade, depending on the cigarette butt composition and the environment. The cellulose acetate in fact is photodegradable but not biodegradable – it needs light to break down. Studies estimate that about 2 billion cigarette butts are littered everyday.
