2. Use and maintenance of the Biolan 

Separating Dry Toilet

Using and maintaining the Separating Dry Toilet in accordance with 

these instructions makes for a much more pleasant experience. 
Separation of the liquid and the solid waste requires that the Sepa-

rating Dry Toilet always be used in the seated position. When using 

the unit for the first few times, verify that your own seating distance 

and habits are suitable for it. Also instruct your guests on how the 

toilet should be used. 
The Separating Dry Toilet is intended for composting toilet waste, in-

cluding toilet paper. But do not put into it anything that could hamper 

the treatment of the waste, such as:

• 

debris, sanitary towels

• 

chemicals, lime

• 

detergents, washing water

• 

matches, ash, cigarette butts

2.1 Before use

Put a layer of Biolan Compost and Toilet Bulking Material a couple 

of centimetres thick on the bottom of the foremost inner receptacle 

(part 5). Fill the bulking material container (part 3) with bulking ma-

terial. 

2.2  Using bulking material

There is a bulking material batcher in the bulking material container 

at the rear of the toilet unit. To use the batcher, press the batcher 

knob (Fig. 1) briskly. The more briskly you press this knob, the far-

ther the bulking material will be thrown. The bulking material does 

not need to be added every time the toilet is used; adding it only 

after defecation is sufficient.

Applying suitable bulking material is essential for proper operation 

of the toilet. For bedding we recommend Biolan Compost and Toilet 

Bulking Material or Biolan Peat (see Accessories on page EN-6). 

2.3  Year-round use of the toilet

The toilet may be used all year round, if installed in a warm space. 

Thermal insulation of the ventilation and liquid removal systems in 

cold areas must then, however, be taken into account. Also provide 

a sufficient gradient to prevent the liquid from freezing in the pipe.

Installed in a cold space, the toilet can freeze during winter. The 

toilet unit is manufactured of frost-proof polyethylene, so freezing 

does not damage it. A toilet located in a cold space can be used 

occasionally during winter. Empty the liquid tank before the liquid 

in it freezes. 
If the liquid is collected in a canister, empty the canister in the au-

tumn in order to avoid damage caused by freezing of the liquid. If 

the bulking material in the container is moist, it may freeze during 

winter. Then the bulking material batcher does not work and you 

must apply the bulking material manually.

2.4  Emptying the inner receptacle

There are two separate inner receptacles inside the tank of the Sep-

arating Dry Toilet (Fig. 2). Use only one receptacle at a time. When 

a receptacle fills up, move it to the back of the unit and put the other 

receptacle into use. As required, level the surface of the waste, for 

example, with a stick. 
The covers for the inner receptacles are intended for use while 

transporting the receptacles for emptying. Leave the lid ajar for stor-

ing. Once both receptacles have filled up, empty the one that filled 

up first into the compost. Disconnect the ventilation pipe (Part 21) 

from the lid of the toilet for emptying (Fig. 3). The flexible ventilation 

pipe will flex at this stage so that you will be able to lift the pipe. 

Tilt the lid of the toilet unit to the side or lift it off, so that you can lift 

the receptacles out of the unit. There is no need to wash the inner 

receptacles when emptying them. 
When replacing the receptacles, make sure to position the recep-

tacle in use correctly against the separating bowl.  Put a layer of 

Biolan Compost and Toilet Bulking Material or Biolan Peat  a couple 

of centimetres thick onto the bottom of the receptacle. Refer to page 

EN-5 for instructions for composting the solid waste from the Sepa-

rating Dry Toilet.
