[USCC] Vertical composting

[Tim Evans]

I think it would work but the adaptation would be expensive because you
would need to put in intermediate floors at say 20 ft intervals.  These live
floors would break up the material as it exited each section and would
prevent the massive compaction to which others have referred.  Without
intermediate floors you would have a stinking, dripping plug of horrible
material in the towers. I guess you would also need some head-space sensors
beneath each intermediate floor to prevent too much from being discharged
from the floor above.  I should think there would be a considerable
convective/chimney effect so whether you would need additional forced
aeration is an open question.

Anyone have any thoughts on converting a number of 25ft diameter, 150
ft. tall concrete grain elevators into vertical composters?     Would it
be possible to deal with compaction and air flow problems at depth of
100+  feet?  What's the deepest pile of compost anyone's heard of?
