A torn up love letter, a wedding dress and a loaded handgun. These are just some of the items discovered during the Ocean Conservancy’s International Coastal Cleanup initiative (ICC). But these intriguing finds aside, year after year cigarette butts are the most commonly found form of ocean litter.
In 2014, ICC volunteers collected some 2m cigarette butts – a huge amount, but just the tip of the iceberg. Approximately 4.5tn of the 6tn cigarettes consumed annually are littered across the globe.
The majority of cigarette waste that ICC collects from beaches is the result of improper disposal. “Many people, even smokers, are not aware that the cigarette filter is comprised of thousands of little particles of plastic,” says Nicolas Mallos, director of Trash Free Seas Program at the Ocean Conservancy in Washington DC. “One solid filter ends up being thousands of tiny fibres that can be released into the marine environment.”
While we know cigarettes damage our bodies, we still don’t fully understand their health implications for our oceans, beyond that other forms of microplastics and microfibres pose a risk to marine organisms. A study from San Diego State University suggests one smoked cigarette butt in a single litre of water is sufficient to kill both marine and freshwater fish, although how this translates from the laboratory to an actual aquatic setting isn’t yet clear.
10 things we learned about tackling plastic ocean waste
The vast majority of cigarette butts collected by ICC volunteers are currently sent to landfill due to a lack of recycling infrastructure. US company Terracycle is aiming to divert this waste and convert it into new products. Its Cigarette Waste Brigade programme, which was launched in Canada in 2012 and encourages smokers to recycle their butts, has since expanded into the US, Australia and Japan. A pilot programme is planned to launch in the UK before the end of the year.

Albe Zakes, Terracycle’s global vice president of communication, says: “The cigarette filter is made from cellulose acetate, which is actually the largest component of most sunglasses, so that material can really get recycled just like regular plastic.”
Because of the stigma around cigarette butts and fear of carcinogens, Terracycle doesn’t use its recycled cigarette butt plastic for consumer products, but Zakes says the end result is 100% free of carcinogens, bio-toxins and nicotine. “It’s just as clean and safe as a recycled plastic bottle would be,” he says.
But if it’s possible to turn such a globally widespread waste stream into commercially viable products, then why aren’t more doing so?
Getting people to collect cigarette butts is one challenge, but the main hurdle is cost. “From a material standpoint, everything can be recycled,
