Thousands of tonnes of plastic pollution could be escaping into the environment every year … from our mouths. Most chewing gum on sale is made from a variety of oil-based synthetic rubbers – similar to the plastic material used in car tyres.
If you find that thought slightly unsettling, you are not alone. I have been researching and speaking about the plastic pollution problem for 15 years. The people I talk to are always surprised, and disgusted, when they find out they’ve been chewing on a lump of malleable plastic. Most manufacturers just don’t advertise what gum is actually made of – they dodge around the detail by listing “gum base” in the ingredients.
