China. According to a study by Chinese scientists, chemicals extracted from cigarette butts help protect steel pipes from corrosion.In the paper published by the journal of the American Society of Chemistry and Engineering, Industrial & Engineering Chemistry Research, the Chinese researchers explain that after immersing the cigarette butts in water they identified nine substances, which they applied to fragments of a type of steel known as N80, which is used in petroleum pipes. obtaining as a result the conservation of steel.
Currently China is the largest smoking nation in the world and consumes a third of the cigarettes on the planet, has 300 million smokers and millions of cigarette butts scattered on the streets, which could be used to prevent corrosion, since chemicals, such as nicotine, seem to be responsible for this anti-corrosion effect.
