7.3 The temperature does not rise
• the thermometer gives indicative information about the vari-
ous stages of the composting process and the temperature
during the hot phase. The hottest part is in the middle, which
the thermometer cannot sense.
• ensure that the mass is sufficiently moist by looking through
the emptying doorway and turning the surface layer over.
The moisture-content is suitable =>
1. when the composting has not yet started (see point 4.1). Con-
tinue the filling in the usual way.
2. the amount of waste is too small to generate the high temper-
ature required. The waste is burning more slowly. Continue the
filling as usual. More decisive than the height of the tempera-
ture is whether the waste has had enough time to decompose
before emptying. If you wish to speed up the composting pro-
cess, add some nitrogen, such as, for example, Biolan Natural
Fertiliser.
3. the compost has decayed to a point, where the hot phase is
already over. Empty some mass from the composter and con-
tinue the use.
The compost mass is too wet =>
• check that the bedding used is Biolan bulking material.
• check that you have added a sufficient amount of Biolan
bulking material.
• adjust the outlet air valve (part 8) on the cover to the position
"extra ventilation" (see point 5.6).
• temporarily increase the amount of bedding applied until the
moisture-content is suitable.
• empty the wettest part of the mass from the composter
through the emptying doorway. Spread it in a layer a couple
of centimetres thick under ornamental plants. The unpleasant
smell will disappear in a few days.
• shovel a couple of spadefuls of Biolan bulking material through
the emptying doorway onto the bottom of the composter.
• drop the mass from above and mix it with a large amount of
Biolan bulking material.
• subsequently, make sure that the mass does not become too
wet.
The compost mass is too dry =>
• sprinkle with warm water.
• return the too-dry waste to the composter from the bottom
after first having sprinkled it.
• subsequently, make sure that the mass remains sufficiently
moist.
7.4 The compost mass freezes
• act before the compost mass has frozen up. Even if the com-
poster's gauge has shown zero for a few days, the composter
can still contain some non-frozen mass. If the composter fills
up, empty it also in winter.
• prevent the freezing by using (filling and emptying) the com-
poster frequently as this sustains the activity of the micro-or-
ganisms. See points 5 and 5.1-5.6. Keep the composter quite
full in winter and empty it frequently.
• pay attention also to the moisture content of the compost
mass, as wet mass freezes more easily (see point 7.3).
• during the winter, apply Biolan bulking material, as well as
gruel mixed from Biolan Natural Fertiliser and warm water to
the surface layer of the compost. Cover it with bedding.
• improve the insulation by piling snow around the composter.
• warm the mass by burying, for example, a canister of 10 litres
filled with hot water into the compost mass and change the
water sufficiently often.
7.5 The compost mass is too tight
• Generously apply Biolan bulking material. Mix the bedding and
the mass.
• Subsequently apply the bedding more generously, and while
filling, make sure that for example grass, root crop peels or
leaves do not form tight layers.
7.6 Flies or their maggots in the composter
The compost is more susceptible to the emergence of flies, if the
mass is too wet. The fly maggots are about one-centimetre long
white worms. See also point 7.3.
• generously apply Biolan bulking material, simultaneously mix-
ing the compost. Use the bedding more generously later on.
• turn the surface layer deeper into the compost. The fly mag-
gots die at a temperature of about +43 ºC.
• apply a layer about 2 cm thick to the surface. After this, make
particularly sure to cover any meat and fish leftovers properly.
• rinse the inner walls and the cover of the composter carefully
with hot water in order to destroy the eggs and maggots.
• as desired, you can do away with the flies using a pyrethrin-
based spray. Consult your local garden centre to select a suit-
able pesticide.
7.7 Ants in the composter
The composter provides the ants with feed and a cosy environ-
ment, which may make it difficult to keep them away. The ants
usually like to stay in the lower part of the composter during the
cooling phase. The ants are not harmful to the composting pro-
cess.
• make sure that the composter is not too dry.
• you can disturb the comfort of the ants by emptying small
batches of compost regularly.
7.8 Mould in the compost
Moulds belong under decomposing organisms of the compost
and their existence is quite normal.
• do not remove mould.
• continue using the composter as usual.
7.9 Fungi in the compost
Fungi decompose the wood material in the compost, such as the
coarse substance of the bedding, and their presence in the com-
post is normal.
• allow fungi to be present in the compost, as they will disap-
pear with time.
• continue using the composter as usual.
