ISO - coffee filter leftovers

I am assuming it is by definition what I don't want. But is there any value in the dried powder left in the coffee filters after making iso?

if you look under scope you'll see lots of spikes, sharp little hairs

I can think of a few uses for such a product.. saybian was talking about it a while back

And will you share

I doubt from iso, but Ive recovered oil from numerous filters treated as trash. When butane was used, these guys threw away dozens of coffee filters loaded up yellow resin was sick. So I pulled them out and hit them w acetone to recover all the hard work left in the filters. Significant to the solvent used, was way worth the effort to swirl some acetone in a glass jar and repeat again. Post extraction to non-polar solvents and acetone is the best, but not for polar solvents.
