According to Slovak media outlet Ciclovivo, the waste management company Odvoz a Likvidácia Odpadu (OLO) in the capital city of Bratislava has proposed an innovative solution to address the pollution caused by cigarette butts in the ocean. The company plans to convert these cigarette butts into asphalt for road construction.
The city is preparing to set up dedicated collectors in public events to collect cigarette butts. Martina Čechová, OLO's Circular Economy Manager, stated, "If participants of festivals, competitions, exhibitions, or other city events could dispose of cigarette butts in the bins, it would not only contribute to environmental cleanliness but also enhance the value of recycling this waste.
The municipal government of the city will collaborate with two companies, SPAK-EKO and EcoButt, to transform collected waste materials into road asphalt. This will be achieved by incorporating cigarette butt filters as an additive in the production of asphalt mixtures.
The EcoButt website explains that the idea behind it originated from a research study published in Australia in 2017, which discussed the use of cigarette butt filter fibers in the construction industry. In 2019, EcoButt partnered with an authorized laboratory to release a research report on the physical and mechanical properties of asphalt made from cigarette butt waste. The results showed that using cigarette butt filters as an additive does not affect its properties.
In addition, EcoButt has developed cellulose acetate fiber particles as a substitute for ordinary cellulose particles. This material does not require the use of wood but is made from discarded cigarette butts. This not only avoids the use of wood from forests but also turns a waste product into a valuable resource. The Bratislava City Council also hopes that this approach will make the streets cleaner.
EcoButt company stated that research shows that a single cigarette butt can contaminate up to 5 liters of water, posing a hazard to life. The company's services include the collection of cigarette butts, the establishment of dedicated trash bins, and the conversion of materials into asphalt, among various other aspects.
Previously, containers specifically for collecting cigarette butts have been introduced at popular artisan Christmas markets in Europe, allowing for the disposal of both traditional and e-cigarette butts. The company has even created a demonstration project, utilizing cigarette butt asphalt to pave a road in Žiar nad Hronom. While the specific details of this road have not been made public, the inclusion of the capital suggests that projects using cigarette butt-derived asphalt hold substantial potential.
