A Second Life for Chewing Gum 再給你一次機會！口香糖洗心革面大作戰 Used gum that is left on the sidewalk is sticky and ugly, but it could be very useful. 雖然被丟在人行道上的口香糖殘渣又黏又醜，但它們可是大有用處喔。
We spend billions of dollars a year worldwide on cleaning up used chewing gum off of our city streets. In fact, gum is the second most common form of litter after cigarettes. It’s a big problem that needs a creative solution. Luckily, a British designer named Anna Bullus thought of an idea to recycle the leftover▼ gum into a wide range of useful items. The main ingredient in chewing gum is man-made rubber, which is a kind of plastic. That means that chewed gum can be recycled and turned into a number of plastic products. Bullus calls her company Gumdrop, and her first product was a trash can for gum. Gumdrop bins▼ are bright pink plastic containers▼ that Bullus and her team place around cities to collect used gum, which is then turned into more Gumdrop products. Her company only needed so many trash cans, so Bullus soon branchedout into other plastic products, including travel mugs, rain boots, mobile phone covers, and more. Bullus and Gumdrop have proven that there are solutions out there for all kinds of sticky problems.
