Runners love their coffee, and during races they need water and other hydration drinks. The most popular method for delivering the drinks continues to be paper cups. And why not? They’re inexpensive, lightweight, and do their job well. And they’re often provided free to races by sponsors such as Absopure.
But the standard cup is lined with polyethylene (PE) – a plastic – to seal the seams and waterproof the paper. The lining makes the cup difficult to recycle. At paper mills that aren’t set up to screen out PE, it can gum up the machinery. Entire bales of paper containing cups could be rejected and end up in a landfill or incinerator. And that’s a shame, because the paper itself is high-quality pulp that is very useful when recycled.
