[USCC] Vertical composting

[A.Niv]

Hello Ronald,

Vertical composting systems exist. They operate quite successfully.
The main problem is to secure aeration and material movement.
The height and compaction is the problem. Aeration of such a
large volume of sitting and compacting material is quite a challenge.
The second challenge is to remove the compacting and bridging
material from the bottom.
The multiple augers system able to remove the bottom layer will cost a
fortune,
The entire mass of 700-800 tons sits on the bottom augers !
Another problem is securing the porosity of the composted mass.
The structural material and organic waste must be very coarse to prevent
the channeling of air forced from the bottom and the resulting hot spots
and anaerobic areas.

To make the long story short - not a good idea. Way to expensive.
