A paper coffee cup takes around 30 years to decompose — far longer than "paper" suggests, because it isn't really just paper.
Why does it take this long?
To hold liquid, the inside is lined with a thin polyethylene film. That plastic layer stops the cup from composting and makes it hard to recycle in standard paper streams. Billions of these cups are thrown away every year.

Frequently asked questions
How long does a paper coffee cup take to decompose?
A paper coffee cup takes approximately 30 years to decompose in nature.
Are paper coffee cups recyclable?
Only at special facilities that can separate the plastic lining. Most curbside programs reject them.
Why don't paper cups compost?
The polyethylene lining blocks water and microbes, so the cup can't break down like plain paper.
