3.3 Maturing cover soil to compost soil
If the cover soil is post-composted, it will mature into proper
compost soil. You can post-compost the cover soil, for example,
in a stack or in a non-insulated composter, because maturing
compost soil does not heat up any longer. For post-composting,
it is advisable to use a composter with a cover, such as (e.g.) the
Biolan Garden Composter or the Biolan Stone Composter to pre-
vent rainwater from flushing away the water-soluble nutrients.
In about a year, the compost matures into compost soil of a dark
brown colour and aggregate structure, from which source sub-
stances, except for bigger wood splinters, can no longer be dis-
tinguished.
4. PROBLEMS THAT MAY OCCUR
4.1 Odour
If correctly installed, used and maintained, the room space where
the Biolan Composting Toilet
eco
is located, remains odourless.
Odour occurs only for a short while after the seat ring lid is lifted
up. This is normal with natural ventilation.
If continuous odour problems persist:
• check that the ventilation pipe has not been blocked.
• check that the ventilation pipe is routed from the toilet unit
(part 13) straight up to the roof, and that it extends over the
roof ridge. If the ventilation pipe is not straight or does not
extend over the roof ridge, repair the installation or improve
the ventilation by installing a separate Biolan Exhaust Ventila-
tor or a Biolan Wind Fan. You can also improve the ventilation
by extending the ventilation pipe.
• make sure that the seep liquid removal system is operational:
the excessive liquid is separated into the canister and will not
spill out from the emptying door to a large extent. As required,
clean the liquid separator plate (part 7), the seep liquid chute
and the seep liquid pipe.
• check that the bulking material used is Biolan Compost and
Toilet Bulking Material. If a mixture of peat and wood shavings
or other beddings of fine texture is used, the compost mass
may be packed too tightly.
• make sure that a sufficient amount of Biolan Compost and
Toilet Bulking Material, about 0.2-0.5 litres, has been applied
after each use. Note that bulking material must also be ap-
plied after urinating.
4.2 Insects or maggots
The most common flies in the composting toilets are small fun-
gus gnats, fruit flies etc. Using a fly net does not prevent these
tiny flies from entering the compost. The fly maggots that are
light in colour, can try to get out of the toilet unit via the seat part,
if the conditions inside the toilet are too hot for them.
The presence of flies in the compost often indicates that the
compost mass is too wet. See also point 4.3.
• check that the bedding used is Biolan Compost and Toilet
Bulking Material. Some beddings (e.g. fresh chips of decidu-
ous trees) attract flies to the compost. The pine bark used in
the Biolan Compost and Toilet Bulking Material, however, acts
as a repellent.
• add a thick layer of bulking material on top of the compost.
• do away with any flying insects in the toilet space using pyre-
thrin-based spray. Consult your local garden centre to select a
suitable pesticide. Repeat the spraying at intervals of at least
two-three days to exterminate the new generations emerg-
ing from eggs and maggots. Spray insecticide also inside the
toilet unit and close the lid. Repeat the spraying until flying
insects can no longer be spotted.
4.3 Moisture
When the composting process is at its most effective, it is nor-
mal that the bottom surface of the seat ring lid is moist. However,
if there is a lot of moisture on the seat ring lid and on the sides of
the seat ring, something is wrong.
Normally the problem occurs in the outlet air system or in the
liquid separator system.
• make sure that the air valve (part 12) in the seat top is open.
• make sure that the ventilation pipe (part 13) has not been
blocked.
• check that the ventilation pipe is routed from the toilet unit
straight up to the roof, and that it extends over the roof ridge.
If the ventilation pipe is not straight or does not extend over
the roof ridge, repair the installation or improve the ventila-
tion by installing a separate Biolan Exhaust Ventilator or a
Biolan Wind Fan. You can also improve the ventilation by ex-
tending the ventilation pipe.
• make sure that the seep liquid removal system is operational:
the excessive liquid is separated into the canister and will not
spill out from the emptying door to a large extent. As required,
clean the liquid separator plate (part 7), the seep liquid chute
and the seep liquid pipe.
• check that the bedding used is Biolan Compost and Toilet
Bulking Material.
• make sure that a sufficient amount of Biolan Compost and
Toilet Bulking Material, about 0.2-0.5 litres, has been applied
after each use. It may prove necessary to double the usage of
bulking material temporarily.
4.4 Liquid runs out from around
the emptying door
At the initial stage, when the toilet is still half empty, or in the
case of overloading, some liquid may leak out from around the
emptying door.
• if it is not a question of initial stage of use or an overloading sit-
uation, clarify potential reasons in accordance with point 4.3.
4.5 Incomplete composting of waste
The reason for incomplete composting of waste is usually that
the mass is either too dry or too wet.
If a lot of decomposed toilet paper is detected while emptying
the compost, the amount of liquid has been too small in relation
to the volume of dry matter:
• make sure that the amount of urine supplied into the toilet is
sufficient. If this is not the case, some liquid must be added.
Urine is best for the purpose, but even water will do.
If the compost is wet or reeks when emptied, its liquid content
is too high:
• make sure that the seep liquid removal system is operational:
the excessive liquid is separated into the canister and will not
spill out from the emptying door (part 3) to a large extent. As
required, clean the liquid separator plate (part 7), the seep liq-
uid chute and the seep liquid pipe.
If the liquid separator system is working properly, the mass is
wet for some other reason.
• check that the bedding used is Biolan Compost and Toilet
Bulking Material.
• make sure that a sufficient amount of Biolan Compost and
Toilet Bulking Material, about 0.2-0.5 litres, has been applied
after each use.
• make sure that the replacement air valve (part 12) in the seat
top is open.
• check that the ventilation pipe has not been blocked.
• check that the ventilation pipe (part 13) is routed from the
toilet unit straight up to the roof, and that it extends over the
roof ridge. If the ventilation pipe is not straight or does not
extend over the roof ridge, repair the installation or improve
the ventilation by installing a separate Biolan Exhaust Ventila-
tor or a Biolan Wind Fan. You can also improve the ventilation
by extending the ventilation pipe.
