There’s a fantastically silly but fun book about this the name of which eludes me.
Mutant 59: The Plastic Eaters, a 1971 British sci-fi environmental disaster novel written by medical scientist Kit Pedler and television screenwriter Gerry Davis.
No wikipedia page, but goodreads has it here:

That wasn’t it; I just found it, it’s called Ill Wind by Kevin J Anderson
Not plastic, but 'Cats Cradle' by Kurt Vonnegut has something kind of like that.
