ScienceDaily (May 14, 2010) — A new study suggests expanding community recycling programs beyond newspapers, beverage containers, and other traditional trash to include an unlikely new potential treasure: Cigarette butts. Terming this tiny trash “one of the most ubiquitous forms of garbage in the world,” the study describes discovery of a way to reuse the remains of cigarettes to prevent steel corrosion that costs oil producers millions of dollars annually. It appears in ACS’ Industrial & Engineering Chemistry Research.

[Scientists Jun Zhao and colleagues] showed that extracts of cigarette butts in water, applied to a type of steel (N80) widely used in the oil industry, protected the steel from rusting even under the harsh conditions, preventing costly damage and interruptions in oil production. .
