Five good reasons to bin your butt. Did you know:

A cigarette butt doesn’t have legs that walk to the bin. Luckily our bins are really close by, so take those few extra steps and bin your butt.

Your cigarette butt is composed of 90% plastic, and plastic doesn’t decay. It breaks down into microplastics. So although you can’t see it, it’s still causing terrible damage.

Once you’ve dropped your smoke bomb, you have 30 minutes before the bomb explodes. In other words: it only takes half an hour for your cigarette to release all its toxic substances into the ground.

And it’s not just fluffy dogs that eat them – butts have been found in the stomachs of fish, birds and walruses. They can cause cancer, heart problems and damage to the nervous system. So it’s a major problem for animals!

Each year, local councils in the Netherlands spend a total of €250 million clearing up litter. And cigarette butts account for 32% of that figure.
