Introduction
HOW YOUR COMPOSTING TOILET WORKS
Composting is a natural recycling process where human
waste and toilet paper are broken down by microbes
into minerals and converted back to earth. Heat, oxy-
gen, organic material and moisture are needed to trans-
form this waste into good fertilizing soil, perfect for your
flower beds.
Oxygen is provided by the ventilation system, and by
tumbling of the composting drum. Additional organic
material is introduced by adding“Compost Sure Blue”
(or 100% shavings). The waste entering the toilet is
approximately 90% water content. Any excess liquid
which is not absorbed will collect on the floor of the unit
(evaporation chamber) where it may be evaporated into
water vapor and carried back to the atmosphere
through the venting system. The remaining waste mate-
rial is transformed into an inoffensive earth-like sub-
stance.
The Composting Chamber
The composting chamber is in the form of a Bio-drum
which holds the natural compost heat, provides the nec-
essary mass to maintain a good compost, and is rotat-
ed by turning the handle to achieve perfect mixing and
aeration.
During mixing, the input door at the top left will remain
closed. When the drum returns to the top dead centre
position ready to receive more waste, the input door will
remain open.
A drum stopper behind the doghouse on the right side
of the unit automatically holds the Bio-drum in a top
dead center position so that it is always positioned to
receive new material.
Compost is extracted from the drum by continuously
feeding into the collection bin (doghouse) whenever the
drum is rotated.
To ensure that the compost remains moist, but does not
get too wet (between 40 and 60% moisture content is
ideal), any excess liquid which the compost cannot
absorb drains through the screen in the bottom of the
drum directly onto an evaporating tray beneath the
screen, and from there, overflows into the larger evap-
orating chamber. The evaporating tray can be removed
periodically to remove peat moss debris that has accu-
mulated.
Compost Collection Drawers
and Chamber
The compost collection drawer is at the extreme right
and left of the unit below the composting drum, and just
above the evaporating chamber. The right drawer is
used only if you wish to completely empty the drum.
The collection drawer on the left is merely to provide
access to the evaporation chamber. Compost from the
drum will automatically feed into a collection chamber at
the far right end of the unit.
Evaporating Chamber
The third chamber is the floor of the Sun-Mar “CENTREX
3000” which forms the evaporation chamber from
where excess liquids are evaporated. You will always
see liquid in this area.

The key to the success of the “CENTREX 3000 ” lies in it’s three chamber design. Each of the three chambers; com-
posting, compost finishing, and evaporation have their own independent environments for optimum efficiency.
