As the Founder of Cigareto,  we developed an innovative device that utilizes a special chemical reaction to transform dissolved used cigarette butts into an industrial anti-rust solution for steel. This project aims to tackle the environmental issue of cigarette waste while providing a sustainable solution for protecting metal surfaces. We successfully pitched this concept in two rounds, showcasing its potential to reduce pollution and promote recycling in a creative way. Through this initiative, we aspire to contribute to a greener future while addressing the practical needs of industries reliant on anti-corrosive solutions.
