I didnt know there was such a thing!
It looks like a reverse coffee grinder, turning ground back into whole bits! It isn't what I'd call cheap, but it could be interesting for the right person to do as a side hustle.
They can be cheap if you can source scrap metal and can weld. The mechanics aren't that difficult. The biggest drawback is time and efficiency as these kinds of operations need to happen at large scales to be profitable. (Machines in this class may be more prone to weird failures, I speculate.)
But yeah, even though we humans have a tendency to waste more than we should, we can be remarkably efficient when profits are involved. Converting trash to treasure has probably minted thousands of millionaires, now that I think about it.
I admire the welders so much. I've done a little welding, but I wouldn't call any of it much better than passable. It really unlocks a whole new level of diy though.
I get a kick about watching some of these people turning various waste products and such into building materials or textiles and that is the stuff that gives me hope for the future. Lots of those operations seem to be those down on their luck in these odd places where these waste materials get pawned off, so I'm glad to see them eventually turned into something useful.
Never underestimate human ingenuity!
