Another thought: the comparison of the inputs and outputs for Terra Firma
and KCDC in Bangalore suggests that there is not a steady relation between
materials taken into a plant and quantities of compost produced.  This
means that there could be an unknown margin of error in predictions made
when designing compost plants of various types.  It is an aspect of the
operation of such plants that should be monitored over time.
