Is this stuff in my filters useful for anything?

I noticed all this brown powder that looks similar to Keif in my filters after making ISO Hash Oil. Is it trash or useful?

I usually have about an 1/8" of kief on top of filter after filtering initial extraction (flower, ethanol extraction). I usually chuck it in garbage as I have extracted the goodness I wanted. Or so I think? I have often wondered this as well.

I do however save the fats, lipids, and waxes from the winterization process. I have approx. 300ml-500ml in a seporatory funnel in the freezer. I havent found a use for them yet but I am sure there is. Such as topicals. How to go about it? Medicinal benefits/uses? I have no idea.
