Washington, May 13 (Inditop.com) Cigarette butts, which are usually thrown in the garbage bin and harm the environment, may find practical use in preventing steel corrosion.
A new study suggests that community recycling programmes can be expanded beyond newspapers, beverage containers, and other traditional trash to include an unlikely new potential treasure: cigarette butts.
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.
Jun Zhao and colleagues cite one estimate that 4.5 trillion cigarette butts find their way into the environment each year, a release of the American Chemical Society (ACS) says.
Studies show that cigarette butts are more than an eyesore. They contain toxins that can kill fish and harm the environment in other ways. Recycling could solve those problems, but finding practical uses for cigarette butts has been difficult.
The scientists 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 harsh conditions, preventing costly damage and interruptions in oil production.
They identified nine chemicals in the extracts, including nicotine, which appear to be responsible for this anti-corrosion effect.
The study appears in ACS’ Industrial & Engineering Chemistry Research, a bi-weekly journal.
