Had a similar experience.

Ran my trim through bags and got 11% by weight of superior bubble hash.

Next day, I took the "spent" leavings and dumped them in a pot of boiling water with a pound of butter.
Simmered for 4 hours.
Filtered, separated, and made cookies with the butter.
Yeeha!

Makes sense.
There are capitate glands that we knock off for the bubble.
There are also glands set deep in the leaf that can not be easily dislodged and there is resin coating most surfaces from ruptured glands as well.
I find that butter makes an excellent solvent for that resin.
And it cooks hot enough to de-caboxylate when the cookies bake, so you really don't need to boil it for more than an hour.

So, that's good advice brah.
Waste nothing, want for nothing.

No gotta take our word for it folks
Try it!
You will be pleased.
(And perhaps a li'l ticked when you realize how much goodness was just getting tossed.)
