25,000 tons of paper cups end up in landfill every year. A thin layer of plastic that can easily be removed may be the solution to this problem as it makes paper cups 100% recyclable.
Conventional paper cups are made from paper laminated with plastic, making them difficult to recycle. Under EU health and safety regulations, coffee cups cannot be made from 100% paper or cardboard alone. A thin layer of plastic is bonded on to the cup to keep the drink warm and stop the paper from getting soggy. But it is attached so tightly that those cups need special facilities to separate the linings, with almost all recycling plants rejecting the cups and sending them straight to landfill.
