everything goes in a pile with the spent soil, sits for a while, gets re-amended (in my case with worms and compost) then reused.
I put my smaller stems and all leaves in a blender and turn it to green mush. Then it's easy to get rid of.
It certainly makes my grows much less messy and easier to dispose of waste. The only waste I have at the end is the roots, stumps/branches, shade leaves and a 3 inch square block of grow wool. BTW I'm not trying to imply what I'm doing is better or worse than anyone else's methods. I just find that works best for me here. I don't want any kind of soil inside my house. I grow in a bedroom.I couldn't grow if I didn't have rockwool.
