50 lbs of coffee grounds a week.

I get a lot of coffee grounds a week. I'm wondering what other folks have any interesting ideas of what to do with that I'm not thinking of...Right now I'm just composting huge piles and plan on putting it on blueberries, strawberries, raspberries. I also inoculated my piles with old oyster mushroom kits my friends have (ten of them).

Not that I can think of. Mushrooms immediately came to mind but it looks like you have a good start on that.

Start some worm bins.

They love coffee grounds, and convert it into one of the finest natural fertilizers you an get.

And they convert it twice as fast as other material

Where do you get coffee grounds? I have been begging around without any luck

Even better coffee husks. I don't generate enough carbon rich material to be able to compost.

I compost some grounds, but they're fine sprinkled straight on the beds (I avoid getting them on plants as you never get it off!
Coffee grounds have a basically neutral ph so if high nitrogen isn't an issue, they can go on pretty thick under mulch.

I get them from starbucks sometimes. But I've heard they use gmo coffee...no real info out there that I've found.
My local cafes are keen to give them away if I provide good buckets and regular removal.

I'm ok about using printed paper. Not exactly nutricious, but it balances out the other stuff. I think shiny paper and coffee grounds are my worms' favourite treat!
