Dr Shengfu Yang appeared on the BBC One Show talking about the chemistry and the recycling of chewing gums.
Our streets and pavements are now suffering from a monstrous plague of spat-out chewing gums, and it costs ~£60 million per annual for removal each year in the UK. Chewing gum wastes have now raised a great concern. The major component making the “chew” of the gums is plastics, which is flexible, stretchable but hard to break down into small molecules. Once they are spat on the street and stepped on, they become little disks that stick strongly with the surfaces, making it very difficult for removal. At the molecular level, this is due to the hydrophobic nature of plastics and the road surfaces, which defines the strong attractive interaction between them.
