I grow mushrooms at home, and so I have lots of spent grow bags with decayed substrate (wood, millet and soy hulls) in them.
They are great for composting, and make very good soil, but nobody wants them and I used as much as I could for my plants.
Right now, I throw them into the industrial compost bin because of that.
But I think they could be used for something way more useful than just compost.
For example, I thought about chopping them up and dehydrating them, so I can use them as cat litter. Mushrooms are mostly water and the hyphae have lots of surface area, so they could act as a sponge.
Or, maybe they burn fine and make good coals for barbecues or heating?
Do you have any other ideas?
What about something like house insulation panels?
I suppose they should be good as acoustic panels for sound absorption as well [ex1, ex2]. Even if they are much smaller I am pretty sure they could be cut and used combined as sound insulation tiles, and them being of different width, length and depth could actually be an advantage.
Mix it into soil, mycorrhiza
O wait… you just use Hydroponics XD
Spread it in a nearby forest to increase their resilience?
You might be on to something with the BBQ idea.
Find somebody with a pelletizer and see if mulching the blocks and making them into pellets works the way you think.

If they burn fine mulched or whole that’s probably fine too, but wood heaters and BBQs would need some specific sized pellet.
Maybe the Minecraft sub can help. :P
Wooden chest, stack them up, no problem!
