unburnable
Won't catch fire
Unburnable describes something that cannot be burned or is resistant to burning.
The term appears in discussions of fire-resistant materials and, more recently, in climate policy: unburnable carbon refers to fossil fuel reserves that must stay in the ground to avoid catastrophic warming.
The documents were printed on unburnable paper.
