Ketubah disposal

So, kind of a bummer question. Within the past nine months, I’ve secured both a secular/civil divorce and a gett from my ex-wife, and for most of that time my very beautifully framed ketubah has just been sitting in the corner of my home office gathering dust. I have now reached the point in my grieving process where I feel ready to dispose of it. My question is, does it need to go to a genizah or can I set it on fire?
