Loredana and Ornella were walking downtown one day, when a gum thrown on the sidewalk ruined their shoes but sparked this idea for Envyrobubble, a gum recycling bin:
We did our homework and realized a public gum container would have to be designed specifically for gum, so we gave it a unique shape. It had to get attention and raise awareness of responsible gum disposal, so we covered it with a fun, eye-catching spiral design and made it scream bubble gum pink. Then we joined forces with a leading recycler to ensure that the gum collected became something useful: fertilizer.
