Composting is a slow but, when
given the time, extremely efficient process ... after 5 years of solid
toilet waste composting, only 1-3% remains ! See diagram below.
Our process is the original Enclosed
Long-term Composting which requires a volume of around three times
the yearly addition of solids (dark blue field)
in order to perform as shown below. Any attempt to make the system
smaller will result in significantly increased maintenance and instability
However, with the proper sizing, the process allows a Clivus
Multrum to be used up to 30 years before emptying of solids is needed.
