Gumdrop:

This is a creation by Anna Bullus, an art student at University of Brighton. She daydreamed to give a seconde life to chewing gum. An average of 30.000 pieces of gum are irresponsibly discarded everyday on Oxford street in London. Cleaning a discarded gum on the street costs three times more than the cost of the gum in the market. She spent eight months in the lab to discover how to recycle the gum. Now she owns a company (Gumdrop Ltd) to produce, from recycled gum, pink bubble bins that will be situated around London.
