Suggestions for CD/DVD destruction

I have several hundred home burned CDs and DVDs that I’d like to destroy before disposing of them. If there were only a handful I’d cut them up but I’d like a time efficient and inexpensive bulk method. I’ve thought of fire, but I’d need a disposable vessel as I am thinking melted discs would be hard to get out of my firepit. Maybe I could line the firepit with tin foil first? Also, are there fume issues with burning discs? Ideally I’d be doing this tonight, I wanted to have a fire this evening but I wore myself out cleaning and moving furniture today.
