Smartphones are just about everywhere. They have become the indispensable electronic device, and the numbers back it up: More than 1.4 billion smartphones were sold worldwide in 2015.
But there’s a flip side to this incredible purchasing trend: electronic waste. In the U.S. alone, more than 150 million smartphones are discarded annually. Consumers who are thrilled to dispose of the old to enjoy the new device and move on to a new one, may not realize how many devices end up in landfills, polluting anywhere between 1,200 to almost 5,000 gallons of ground water per device.
