MANUAL FOR
ASSEMBLY AND USE

CONGRATULATIONS FOR YOUR
GREAT ECOLOGICAL CHOICE!
The use of a dry toilet represents nutrient recycling at its best in your own yard.
For example, when a family of four uses a Green Toilet, the save of clean water can be up
to 120 liters per day. Also, a lot of energy is saved, because there is no black wastewater to
be transported and purified elsewhere.
Instead, by composting your toilet waste, you will get nutritious mulch to be used in your
own garden – for free!

PREPARATION OF ASSEMBLY
The composting power of the Green Toilet is based on the capillary double base. It works
like an underwatering flower pot: It lets the excess liquid out, but can also absorb some of
the liquid back to the compost mass. This will ensure eicient composting, as the compost
works at its best when it is moist enough: not too dry, not too wet.
It’s a good idea to reserve enough
space for maintenance behind the
outhouse so that changing the
containers can be done easily. You
can also leave the full container to
decompose behind the outhouse if
there is space for that.

Before you start, check that you have received all the necessary parts.
A list of the package contents is shown on the last page of this manual.
In order for the composting
to start, it is important to
cover the double base with
some dry material. Start
using Green Toilet by
pouring a layer of dry
material (5-15 cm): peat,
saw dust or equivalent, onto
the double base of the toilet
container. Fill also the hollow
legs of the double base with
the dry material.
Remember to do this
covering every time you take
an empty container into use.
No dry material is put into
the boom of the container.
There will be some excess
liquid during the use of the
toilet.
PREPARATION OF ASSEMBLY

ASSEMBLY
Green Toilet is usually assembled from the back of an outhouse under a bench below the
toilet seat hole. The height of the waste pipe can be adjusted vertically.
ASSEMBLY
Assembly of waste pipe and thermal seat
There are wooden rails for the waste pipe included in the package. They are assembled on
both sides of the hole in the seat to hold the waste pipe during the use of the toilet. The
upper part of the waste pipe is wedged between the wooden rails and the toilet bench. If
the bench is close to the container and some of the waste pipe goes into the container, the
pipe can be cut shorter by saw. It is best to have about 2 cm of waste pipe going into the
composting container.

Hint! If you have to bend and make curves to the ventilation pipe,
it’s a good idea to add a wind fan (an accessory) to the top of the
pipe to boost dehydration and ventilation.
5ASSEMBLY
The openings for the seat tend to vary in outhouses – there is no standard. Usually this is
not a problem when assembling the Green Toilet. Just level the thermal seat, the opening
of the seat and the waste pipe in the front of the seat. Thus, the use of the toilet will be
clean and hygienic.
There is a thermal seat included in the Green Toilet package with separate installation
instructions.
Assembly of ventilation
The ventilation pipe should be led as straight as possible to the roof level. Usually, it is
assembled to the back of the outhouse wall with the metal holders, which can be bent for
fixing to the wall. With the flexible pipe, you can adjust where to fix the pipe.
Also, a ventilation pipe hat is included, and it is placed to the top to prevent any rainfall. If
the outhouse roof is wide, it maybe necessary to make an inlet for the ventilation pipe
through the roof.
When the place for the Green Toilet is ready and the ventilation duct fixed, you can place
the Green Toilet container below the seat. Finally, aach the flexible pipe, liquid hose and
the canister.

6
Assembly of canister for excess liquid
With the Green Toilet, there is a 20-liter canister supplied. It is used to collect the excess
liquid (seap liquid) coming out of the composter during the use. Most of the liquid is
absorbed to the compost mass, dehydrated through ventilation, but some will flow into the
canister. The amount of the seap liquid is highly dependent on the use and environment.
The liquid hose should flow a bit downwards. If the ground can be dug, you can make a
hole with boards on each side for the canister.
Other remarks of installation and use
The wheels for Green Toilet should be used in the container that needs to be moved. The
container in use should be without the wheels. You can put the wheels easily: Just lift the
container a bit and place the axel to its position in the back. No tools are needed.
Sometimes the distance from the seat to the ground is so long, that the Green Toilet waste
pipe is not enough. In these cases, contact your dealer to have a longer waste pipe.
ASSEMBLY
Hint! There is a wide variety of accessories for the Green Toilet
available. They may be handy if there is exceptionally high use for
the toilet or the installation is somehow unusual. Contact your
dealer for more information.

7USING GREEN TOILET
USING GREEN TOILET
Now that you have installed the Green Toilet – you can start using it!
Green Toilet can be used almost like a water closet – there just is no flushing. All toilet
waste, including the toilet paper, go into the same container. For other garbage, like
sanitary pads, there should be a separate bin available in the toilet.
After every use, pour some 3-5 dl of dry material on the compost. You can use any dry
material that you can acquire easily. Also, dry garden waste, like dry leaves can be used as
bulking agent. Saw dust also works, but it should be mixed with some more coarse mate-
rial, as saw dust tends to get too dense in the compost.
During the use, you need to level the mass every now and then. A garden fork or a sturdy
stick will be good for this. At the same it is useful to aerate the compost mass by making
some holes to the mass.
There are some biodegraders and compost boosters available in the market and they can
be used. This may be useful especially during high use of the toilet.
Hint! The composting inside the Green Toilet works best when the container is
almost full. There is a lot of energy and microbes in the compost and the process is
fast. So don’t be too hasty in changing the containers! Level and work on the mass
to get more space into the container. This may help postponing the change of the
containers for many weeks.
MAINTENANCE AND EMPTYING
Handling of excess liquid
During the use of the Green Toilet, there usually is need to empty the excess liquid canister
before the composting container gets full. The amount of this seap liquid depends on many
factors, like the temperature and level of use. It is typical, that during hot summer months
the dehydration and composting reduce the amount of the liquid almost to zero. On the
other hand, during colder months one can expect that there is more liquid to be handled. It
is important to check the level of the canister regularly.

The excess liquid is nutritious liquid – an eco-fertilizer. There are a few ways to use it: you
can pour it directly to a compost, eg. to a full Green Toilet spare container, where the urea
will boost the process. Alternatively, you can use it directly to non-eatable plants, trees or
bushes for fertilization.
MAINTENANCE AND EMPTYING
Please note! Do not pour any seap liquid to:
any water body. In water the seap liquid will cause eutrophication and the
fecal bacteria will spread. Remember to always keep a safe distance to any
water: ditch, well, lake, sea etc.
eatable plants, like vegetables, because there is a risk that the bacteria is
carried to the food.
Changing Green Toilet container
When the active Green Toilet composting unit becomes full, it is time to change the
container. Here are the steps to follow:
Release the flexible ventilation pipe from the container.
Unfasten the liquid hose from the container. Cover your hands and beware
of possible splash when doing this. If small amount of liquid is drained out to
the ground at this point – that is not harmful.
Place the wheels under the container.
Pull the container out from the outhouse and tilt the container on the
wheels. Now you can pull the container further away from the outhouse.
Put the closed Green Toilet lid onto the full container and leave it to decom-
pose.
Take the empty container and cover the double boom with dry material.
Place the Green Toilet lid with the waste shaft on to the empty container and
wheel it into the outhouse. Aach the liquid hose and the flexible ventilation

If there is no spare container available, you can take the compost from the toilet to a
garden composter, mix it with garden waste and let it decompose to the end there.

9COMPOSTING TOILET WASTE
Hint! It’s a good idea to store the spare container close to the outhouse. When the
Green Toilet is taken out of the toilet, the compost can still be fairly wet and the
mass heavy. During storage and composting, the volume of the mass, together
with the weight, will go down significantly – even by half. Thus, the container will be
much easier to wheel after a few months of storage.
COMPOSTING TOILET WASTE
Usually it is prohibited to let raw toilet waste untreated to the ground. This is especially
harmful in water areas, like in lakes, where toilet waste causes eutrophication. The Green
Toilet system will help you to manage sanitation in your own yard safely and easily.
The time needed for the composting varies in dierent areas. The normal time span is 8-14
months, depending on the climate. In many cases, you can rely on your senses: if the
compost smells like mulch and looks like mulch – it can most likely be used freely. The
compost from a dry toilet is very nutritious, so one should mix at least one third of other
material: sand, mulch, clay etc. before using it for plants.
Can you compost other bio waste (like kitchen waste) in the Green Toilet?
It is possible, but it also brings higher risk for flies and other insects in the toilet.
Therefore many prefer to have kitchen waste in a separate composter or
alternatively in the passive Green Toilet, ie. in the spare container.
You can empty a full container by taking it first to a suitable place and turning it around
fully. After this, it is advised to mix the compost with eg. sand to get suitable mulch to be
used in the garden.

WINTER USE AND ACCESSORIES
USING GREEN TOILET IN THE WINTER
Green Toilet is manufactured so that it can freeze without breaking, even if it’s full of
compost. If the Green Toilet is mainly used during the summer months, there is no need to
do anything special. If the compost freezes during the winter, it will melt down in the spring
and composting will continue normally.
If the toilet is used all year round in cold climate, it should be taken into account already in
the assembly phase. If possible, the composting unit should be placed into a heated space
or an insulated box should be built for it. Also, in the coldest areas, a frost protection cable
can be utilized.
