This is an amazing discovery:
Jun Zhao, a Ph.D. student in the School of Energy and Power Engineering at Xi’an Jiaotong University in China, and a team of scientists found that cigarette butts can be put to good use. Their study, which is published in the American Chemical Society journal Industrial & Engineering Chemistry Research, shows that extracts of cigarette butts that have been submerged in water can help prevent steel from rusting.
Application of the cigarette material to N80, a type of steel, could save millions of dollars a year that oil industries spend on steel repair, the study says. The research suggests that nine chemicals in cigarette butts, including nicotine, work to inhibit corrosion.
