If you were really clever, you'd take your material, and put it in a bag with 120 micron screen. Add a couple appropriate sized chunks of dry ice to bag. Shake like hell over a glass top table. Scrape every bit into a much smaller 90 micron bag. Tie shut.

Set up double boiler. Put in one cup of coconut oil, and 2 of your little bags. Run it for about an hour.

Use that oil in your brownies.

Squeeze dry then throw the little bags away. Mixing the oil in means it will now destroy lung tissue.

Your material can be basically trim waste, won't matter.

I'd use a baking pan for the brownie part though, not a pot.
