Gum recycling bins

While it may not be at the forefront of even the most eco-driven minds, chewing gum is littering sidewalks, city centers, schools and other public places—and there are better uses for it than collecting on the bottoms of our favourite shoes, according to two new start-ups that are out to solve the gum littering problem. Canadian Envyrobubble and British Gummy Bins offer tidy collection bins for pedestrians to deposit their chewed out pieces of gum.
