British Designer Recycles Used Chewing Gum Into Everyday Items—Including the Soles of Shoes
Even if you never chew gum, you may have stepped on a gob of the stuff discarded on a sidewalk or felt it stuck beneath a park bench. Chewing gum is the second most common source of litter, behind cigarettes, and because it isn't biodegradable, cities are struggling to get rid of it. Now, the BBC reports that British designer Anna Bullus has found an ingenious alternative to tossing old gum on the ground: She's repurposing it into new products normally made out of rubber or plastic.
Bullus started her gum recycling project by installing bright pink bins called Gumdrops around sites in the UK. The containers, which are made from recycled gum themselves, come with signs telling passersby that any old gum dropped into the bin will be recycled. In some places, the receptacles led to an 89 percent decrease in gum litter.
After analyzing the chemistry of chewing gum, Bullus found that it contains polyisobutylene, a type of polymer similar to plastic that's often used as a synthetic rubber. This means it can be used to make everyday products like doorstops, coffee cups, and plasticware. It can even been turned into playful pink soles for shoes, which look much more attractive than the gum that normally ends up on the bottom of your shoe.
The collected gum is processed with other plastic polymers at a recycling plant in Worcester, and from there it's sent to a plastic molding specialist in Leicester, where Bullus executes her designs. Combs, lunchboxes, pencils, Frisbees and many other items made from gum are available to order from the Gumdrop website. Anna Bullus is also accepting suggestions of other products to make from the chewed-up gum she collects.
