How does a composting toilet work?

The way a compost toilet works is quite simple: A special separator is used to collect urine and solids in separate containers. Urine is either collected in a urine container located at the front of the toilet or diverted to an external container outside the toilet via a siphon and hose. Solids, on the other hand, fall into a bucket at the back of the toilet. It is lined with a compostable bag that contains at least two handfuls of cover material. After going number 2, cover the solid waste with as much cover material as needed to remove moisture from the solids. This helps to keep unpleasant odors at bay. It is worth noting that this type of toilet system doesn’t require water to flush down human waste, making it an environmentally friendly solution. For more information, check out this blog article.

Do compost toilets smell?

You don’t have to worry about unpleasant odors provided that you use the compost toilet correctly. It is really important to use enough cover material as it removes moisture and odors. As a rule of thumb, the litter should cover the solids completely. The cover material ensures that solids dry properly, thus eliminating odors. In poorly ventilated rooms or rooms with high humidity (e.g., bathrooms in RVs), we recommend that you use a fan. The additional airflow speeds up the drying process and prevents smells from getting trapped. If urine comes into contact with oxygen, ammonia is produced after some time, which has a very strong odor. This is the reason why you should empty the urine container every day or every other day. In addition, we recommend our Spillguard Kit as leakage and odor protection. Ideally, you will also have a spray bottle with some mild detergent (e.g., beeta ecological cleaner) or a mixture of water and vinegar (at a ratio of 1:1) at hand. Spray 2 to 3 times after peeing to “flush” the toilet. This ensures that no urine residue remains in the separator.

How do I find the right model? / What is the difference between the models?

Here you can find an overview of all our toilet models. You can use the filter options in our online shop to search by size, capacity, etc.

Do I need a fan?

Since the cover material is extremely effective, you don’t necessarily need a fan. However, it’s a good idea to use one in rooms with high humidity (e.g., due to showering or bathing) and/or in poorly ventilated rooms. Otherwise, the solids won’t dry properly, which will give rise to bad smells. In fact, around 60–70% of our customers use their compost toilet successfully without a fan. If you are still undecided about whether to use a fan or not, don’t worry. You can always install it at a later time. The respective sawing templates are available free of charge in our support area. You can purchase the 5 V and 12 V fan set separately in our online shop under “Equipment”.

What equipment do I need?

Most importantly:

Suitable cover material (e.g., miscanthus)
Compostable bags
The Spillguard Kit as leakage and odor protection
A spray bottle containing either a mild detergent (e.g., beeta ecological cleaner) or a mixture of water and vinegar (at a ratio of 1:1) to “flush” the toilet after peeing. Spraying 2 to 3 times is sufficient.

Odor control — Spillguard Kit or siphon?

Use the Spillguard Kit as leakage and odor protection if the urine container is inside your toilet. This is the case with all our toilets, except the FancyLoo Divert. A siphon, on the other hand, is the right choice if you divert the urine to an external container (e.g., a urine container outside the toilet). You can’t combine the two products because the siphon and the container don’t fit inside the toilet at the same time.

Use & Disposal

How to prep a compost toilet

Before you start using the compost toilet, line the solids container with two bags. Why two, you ask? Just to be on the safe side if one bag tears. Then place at least two handfuls of cover material in the lined container to speed up the drying process from below. Put both the urine and the solids container inside the toilet and you are good to go!

How to use a composting toilet

You can use your compost toilet like a normal toilet. Just open the lid and sit down. You don’t have to worry about anything: The design of the separator ensures that urine and solids are collected separately in the designated containers. All toilet paper goes into the solids container. It’s really important to use enough cover material as it removes moisture and odors. As a rule of thumb, the litter should completely cover the solids. Here you can find an illustrated step-by-step guide.

How often do I need to empty the composting toilet?

There is no one-size-fits-all answer as it depends on the model and its capacity (see table). When urine is exposed to oxygen, ammonia is formed after a while, which has a strong odor. This is why we recommend that you empty the urine container at least every other day. Empty the solids container at a fill level of about three quarters.

Model	Urine container	Solids container
Fancy Loo	9.5 l (2.5 gal.) = going to the toilet 23 times	16 l (4.2 gal.) = going to the toilet 17 times
EasyLoo	9.5 l (2.5 gal.) = going to the toilet 23 times	16 l (4.2 gal.) = going to the toilet 17 times
MiniLoo	9.5 l (2.5 gal.) = going to the toilet 23 times	9.5 l (2.5 gal.) = going to the toilet 12 times
MicroLoo	5 l (1.3 gal.) = going to the toilet 12 times	5.5 l (1.5 gal.) = going to the toilet 7 times
PiccoLoo	5 l (1.3 gal.) = going to the toilet 12 times	5.5 l (1.5 gal.) = going to the toilet 7 times

How to empty the composting toilet?

First open the separator and take out both the urine and the solids container.
• Emptying the solids container:
Remove the bag from the solids container and seal it tightly. Dispose of it in the garbage can for residual waste. Throwing it into the garbage can for organic waste is forbidden. An alternative is composting. Here you can find more information on this topic.
• Emptying the urine container:
To stir up any urinary solids that have settled at the bottom of the urine container, shake the container vigorously for a moment. This makes it easier to get them out when you empty it. Either pour the urine down a drain (e.g., in a public toilet) or dilute it with water and use it as a fertilizer. Note, however, that each plant reacts differently to urine as fertilizer. Here you can find more information on this topic.

Where to empty a composting toilet?

You can either throw the solids into the garbage can for residual waste (never into the garbage can for organic waste) or compost it. Detailed information on composting is available here.
Urine can simply be poured down a drain (e.g., in a public toilet). It’s not allowed to empty it into a storm drain as the urine would flow directly into local waters without prior treatment. Diluted with water, it makes a great fertilizer for many plants. Here you can find more information on this topic.

How to dispose of the urine?

Disposing of urine is easy: You can simply pour it down a drain (e.g., in a public toilet). It may not be emptied into a storm drain as the urine would flow directly into local waters without prior treatment. Diluting the urine with water and using it as a fertilizer is an eco-friendly alternative. Note, however, that each plant reacts differently to urine as a fertilizer. Here you can find more information on this topic.

What bags can I use for composting toilets?

We recommend biodegradable garbage bags made of corn starch because they are suitable for composting. If you put the solids in the garbage can for residual waste, you can also use regular garbage bags. Just make sure to use tear-resistant ones to avoid any mess.

How long can you store the bags?

Compostable bags do start to decompose after a certain time. But if you store them away from sunlight and moisture, you can keep them for about two years.

What’s the best cover material for a composting toilet?

Its properties make miscanthus an excellent cover material.

Miscanthus is:
•   Highly absorbent and binds odors thanks to its open pores
•   Virtually dust-free and therefore ideal for allergy sufferers
•   Fast-growing and climate-friendly
•   Produced locally, binds CO2 and protects the soil because it’s never completely harvested

Click here to find out more about miscanthus and cover material in general.

Can I use sawdust in a compost toilet?

Yes, you can. You can use both sawdust and small animal litter. They have the same moisture-absorbing properties as miscanthus. However, miscanthus produces considerably less dirt and dust. Some customers noticed unpleasant odors when using small animal litter, which was no longer the case when they used miscanthus as a binder instead.

Can you use kitty litter in a compost toilet?

We strongly advise against using kitty litter as a cover material, as we have heard from several customers that it doesn’t absorb odors effectively. Another disadvantage of kitty litter is that it cannot be composted.

How long will 17 liters of miscanthus last?

If two people use miscanthus as a cover material every day, 17 liters (4.5 gallons) will last an average of 18 days. So with one bag of Miscanthus about 37 uses are possible. This involves 4 bag changes. Recommendation: it is best to put 2 bags in the solids tank to be on the safe side. Of course, these numbers also depend heavily on individual consumption. It is important that the solids are completely covered after using. The number of bag changes refers to our 16 liter solids tank in combination with our 30 liter compostable waste bags.

What toilet paper can I use for compost toilets?

If you want to compost the solid waste, use unscented and unbleached toilet paper. Note: Recycled paper may contain BPA. Choose, for example, toilet paper made of bamboo, which is one of the fastest-growing plants on earth. When disposing of the solids as residual waste, you can use any toilet paper. You can even throw moist toilet tissues into the solids container.

Can I use a bum shower?

For a dry compost toilet to be odor-free, the separation of liquids and solids is essential. Therefore, no liquids should get into the solids container. Otherwise, unpleasant odors will arise. If you don’t want to go without your bum shower, have a separate bowl ready for this purpose and dispose of the water afterwards. Moist toilet tissues are a convenient alternative, but only if you dispose of the solids as residual waste. You may not compost them, as they often contain plastic.

Are compost toilets suitable for women?

Yes, compost toilets are equally suitable for women and men, because our urine separators take into account both the female and male anatomy. If you have doubts at the beginning, you can adjust your sitting position to what feels best. For example, move a little further forward or backward on the toilet seat.

Are compost toilets suitable for children?

Yes, from a height of 1 meter (3 feet), the separation of liquids and solids also works well for children. The best sitting position for children who are less than 1 meter (3 feet) tall is above the back opening for solid waste. Urine will inevitably end up in the solids container, but such small amounts are usually not a problem for the cover material. However, if larger amounts of urine get into the solids container, it’s important to add extra cover material (e.g., pressed straw pellets) and to empty the solids container more often. There is no special child seat; conventional toilet seats for children are not suitable.

Composting toilets and periods

You may throw feminine hygiene products like pads and tampons into the solids container, provided that you do not compost the solids but dispose of them as residual waste. Pour the blood from your menstrual cup into either container. If you pour it into the solids container, cover it with enough litter. You can remove blood residue in the separator using a mild detergent so that it flows into the urine container. Here you can find more information about the topic as well as a personal report.

Can I use the compost toilet when I have diarrhea?

Yes, you can use the compost toilet when you have diarrhea. If that’s the case, we recommend that you change the bags more often and add more cover material than usual to help bind the extra liquid. If the diarrhea is due to an illness, do not compost the solid waste. Instead, seal the bag tightly and dispose of it in the garbage can for residual waste.

Can I vomit into a compost toilet?

Yes, you can use the compost toilet if you have to vomit. However, in such a case, we recommend that you change the bags more often and add more cover material than usual to help bind the extra liquid. If an illness is the reason for your vomiting, please refrain from composting the solid waste. Instead, seal the bag tightly and dispose of it in the garbage can for residual waste.

What can I throw into the solids container?

The following may go into the solids container:
•   Solids
•   Cover material
•   Toilet paper
When disposing of the solids as residual waste, you can also put feminine hygiene products or moist toilet tissues into the solids container.

Urine gets into the solids container

That may happen and is due to the fact that the female urethra (but also the male urethra) is rarely perfectly straight. If only small amounts of urine enter the solids container, the cover material usually absorbs it without any problems. If there is more urine than the cover material can absorb and it starts to smell bad, place a handful of pressed straw pellets in the solids container once a day and empty it more often if necessary. Please note that urine may also get into the solids container if children less than 1 meter (3 feet) tall use the compost toilet.

How to clean the urine separator

The good news is that the urine separator is easy to clean, as its surface is very smooth and without any edges. If you use the toilet on a daily basis, we recommend that you clean the urine separator once a day. To do so, spray it with a mild detergent Then grab some toilet paper, for example, and wipe it thoroughly. Alternatively, you can “flush” the toilet with a mixture of water and vinegar at a ratio of 1:1 after going number 1. In addition, we recommend that you clean the underside of the urine outlet once a week to prevent residue from accumulating. The procedure is the same as above: Spray and wipe.

Can I use vinegar for cleaning?

Yes, vinegar is ideal for cleaning the separator. Among other things, it’s cheap, organic and effective. However, you should use undiluted vinegar only in exceptional cases. It’s best to mix it with water at a ratio of 1:1. You can fill this mixture into a spray bottle and store it next to the toilet, for example. Make sure that the mixture is balanced. If it contains too much water, the urine may start to smell bad. Ideally, the vinegar should have an acidity of 5–7%. Please do not use vinegar essence and apple cider vinegar.

Can I use citric acid for cleaning?

Yes, you can clean the urine separator with citric acid instead of vinegar (if you don’t like the smell of vinegar, for example). Make sure to use only liquid citric acid. Mix it with water, also at a ratio of 1:1. Do not use granular citric acid: Although it initially dissolves in water, small crystals form again when the water evaporates. They can scratch the urine separator.

What other detergents can I use for cleaning?

In principle, you can use any detergent without chlorine, alcohol, plasticizers, a high acidity or abrasive particles. If you are not sure whether your preferred detergent is suitable, test the product on a small, discreet part on the underside of the separator. Preferably choose biodegradable detergents.

How to clean the urine container

It’s advisable to clean the urine container thoroughly at regular intervals. This means: After emptying it, rinse it with water and wipe it dry both on the inside and outside. Should you notice residue in the urine container after some time, you can remove it with a coarse sponge.
What if the residue is particularly stubborn? Heat water to about 70°C (158°F), pour it into the urine container, add some vinegar or citric acid and let it sit for a while. The vinegar or citric acid removes the residue and the hot water kills viruses and bacteria.
Tip: If you add a tablespoon of vinegar into the container after emptying it, hardly any residue will accumulate and the vinegar will neutralize the urine smell.

How to clean the solids container

Generally, there is no need to clean the solids container, as it is protected by a bag (or two bags for those who want to be on the safe side). However, if there is an incident or condensation, you can simply wash it. Dry it thoroughly and it’s ready for use again

How to clean the siphon

You should also clean the siphon regularly, as residue such as urine scale can build up in it and clog the outlet. This rarely happens, but it’s possible. You can prevent this by periodically running a mixture of water and vinegar (at a ratio of 1:1) through the siphon. If you know you won’t be using your compost toilet for a while, we recommend that you run at least 1 liter (0.3 gal.) of the mixture through the siphon. By doing so, you both clean it and neutralize any smell. If the siphon is already somewhat clogged and the urine no longer drains properly, remove the siphon and disassemble it. Next, clean all the parts and reassemble and reinstall it. Click here to access our building instructions for the siphon.

How to clean the Spillguard Kit

You should also clean the Spillguard Kit from time to time. Even though the accumulation of residue is very unlikely, the silicone may start to smell of urine after some time. If this is the case, you can simply boil the Spillguard Kit for a short time. To neutralize the smell, pour a bit of vinegar or citric acid into the boiling water. No worries: Silicone does not deform in the process.

Smell

Do I need a fan?

Odor control — Spillguard Kit or siphon?

How can I make the urine and solids containers leakproof for safe transportation?

Close the solids container using the lid provided. Put it on only for transportation, as otherwise moisture will get trapped inside the container. This would prevent the solid waste from drying properly and cause foul odors. Use the Spillguard Kit to seal the urine container tightly. It fits all our toilets, except the PiccoLoo. For this model, you can use the Spillguard Plug. If the urine container is inside the toilet, you can’t close it with the lid included in the delivery. Why? The urine separator extends too far into the container.

My compost toilet smells of urine.

Tip 1: Use a mild detergent to ensure that no urine residue, which is a potential source of odor, remains in the separator. We recommend, for example, a mixture of water and vinegar at a ratio of 1:1. Spray 2 to 3 times to “flush” the toilet after peeing.

Tip 2: Pour a tablespoon of vinegar into the empty urine container to delay the formation of bad odors.

Tip 3: Empty the urine container every day or every other day. This way, you avoid the smell of ammonia, which is produced when urine is exposed to oxygen.

Tip 4: We also recommend that you use the Spillguard Kit so that less oxygen enters the urine container.

Side note: If you drink enough water or other fluids, fresh urine usually doesn’t have a bad smell

How to keep a composting toilet from smelling

If the humidity level in the solids container is too high, this can cause bad odors. Therefore, remember to always use enough cover material. You can equip your toilet with a fan at any time. Should urine get into the solids container (for example, if small children use the toilet), add extra cover material or absorbent straw pellets.

My urine container/Spillguard Kit smells bad. What should I do?

Urine container:
If your urine container smells bad, we recommend that you pour hot water and some vinegar into the container. Let it sit for a while. The water temperature should be at least 70 °C (160 °F) so that viruses and bacteria don’t stand a chance. Then take a sponge and thoroughly clean the inside of the container. This should neutralize the smell.
Spillguard Kit:
If the Spillguard Kit has a bad smell, you can boil it in water mixed with some vinegar for about 10 minutes. After that, it should be free of any odors

Products

What differences are there between the urine separators?

First things first: The internal dimensions of the urine separators are the same. The main difference is that the Klassik and XL Klassik models have a rim at the back and an additional opening for solid waste. This opening extends downwards like a tube and ensures that the solids land safely in the bucket and the inside of the toilet doesn’t get dirty. The Kompakt separator has no opening for solid waste, only for liquid waste. If you want to use the toilet only as a urinal or if your toilet is very compact, this urine separator is a great choice. The external dimensions of the XL Klassik separator are larger than those of the Klassik version. Thus, the entire surface is made of hygienic plastic. You can easily cut the XL Klassik separator to size using a jigsaw at the lowest speed.

Does the urine outlet have a conical shape?

Yes, the urine outlet has a conical shape. It measures 3.7 cm (1.5 in) at the top and 3.4 cm (1.3 in) at the bottom.

What is the difference between the 5 V and 12 V fan? / Which one is the better option for me?

The 5-volt fan has a USB port. It can either be powered by our solar panel or be connected to an outlet via an adapter (e.g., phone charger). The 12-volt fan can be integrated into the onboard power supply, provided that there is already an existing 12-volt power supply in the RV.

How does the Spillguard Kit work?

The Spillguard Kit consists of two parts:

• Screw-on lid for the urine container with a silicone ring
• Silicone plug inserted from above

When used in combination, neither liquids nor odors can escape from the compost toilet. The Spillguard Kit acts as an airtight, moisture-proof seal and prevents oxygen from entering the urine container. This significantly delays the formation of smelly ammonia, which is released when urine is exposed to air. Furthermore, it prevents urine spillage while on the go.
Spillguard Kit Detailansicht

Can I use the Spillguard Kit for the PiccoLoo?

No, you cannot use the Spillguard Kit for the compact PiccoLoo. However, you can use the Spillguard Plug separately to control odors. Please note that the plug doesn’t provide leakage protection on bumpy rides.

Can I use the Spillguard Kit and the siphon at the same time?

No, you can’t combine the two products because the siphon and the container don’t fit inside the toilet at the same time. We recommend that you use a siphon only if you want to divert the urine to an external container. Otherwise, the Spillguard Kit is your go-to when it comes to preventing smells and spillage.

How does the siphon work?

The purpose of a siphon is to create a protective barrier against foul odors. It is based on the principle that there is always some liquid inside the siphon. This prevents smells caused by waste from entering your living space. In the case of a compost toilet, the fresh odorless urine suppresses the odors of the old urine in the external container. Please note that fresh urine is odorless only if you drink enough water or other fluids.

At what angle does liquid leak from the siphon?

The siphon will not leak until it is tilted more than 40 degrees.

How do I connect the siphon to an external container?

Technical questions

Do I need to treat the wood of the toilets?

Yes, because all our toilets except the FancyLoo are made of untreated birch plywood. Therefore — after assembly — it’s important to treat the wood of the toilets on the inside and outside to protect it from moisture and potential contamination. We recommend, for example, stair and parquet varnish as it’s particularly resistant. It’s also an opportunity to get creative. Here you will find inspiration to customize your toilet.

Should I treat the wood before or after assembly?

Please treat the wood on the inside and outside AFTER assembly. Otherwise, the glue won’t stick properly. This applies to all models except the FancyLoo.

Has the toilet seat been treated?

Yes, all toilet seats — both bamboo toilet seats and magnet toilet seats — have been treated.

Which glue should I use for attaching the urine separator?

Preferably, use a glue for vinyl flooring or Sikaflex. Sand the underside of the separator and apply the glue with a notched trowel. Let the carrier material glued to the separator dry under pressure for at least 24 hours. It’s vital that the glue dries completely.

Can I turn a Thetford chemical toilet into a compost toilet?

The easiest way is to remove the Thetford chemical toilet and to replace it with a compost toilet. For more information, check out our blog.

Can I turn a standard toilet into a compost toilet?

Although standard toilets have the same internal dimensions as our separators, a standard ceramic bowl is unfortunately not suitable for this purpose. It’s very difficult to collect the liquid and solid waste separately inside the toilet.

Does the fan have to be vented to the outside?

The answer is yes. The fan needs to be vented to the outside. Since it plays a significant role in drying the solids, moisture should be directed out of the room.

What can I connect to the fan flange?

We recommend one of the following two options.
Option 1: You can use a commercially available HT pipe with a diameter of 5 cm (2 in). It’s available in any hardware store at low cost. Just connect it to the stainless steel flange.
Option 2: You can use a flexible aluminum pipe with a diameter of 5 cm (2 in), which you can also buy at any hardware store. It should be secured with a hose clamp.

How do I connect the 12 V fan?

The 12-volt fan set is fitted with a two-pin plug that is already connected to the fan’s wiring harness. As illustrated on the bag, the blue wire represents the positive (+) pole and the white wire represents the negative (–) pole. You can see the colors of the cables directly at the plug. The supplied counterpart of the plug must now be connected to the two cables of the vehicle’s electrical system in accordance with the assembly instructions (fan set 12 V). Please be careful not to confuse + and –. In such a case, the switch would light up but the fan wouldn’t work.

What is the maximum length of the exhaust duct?

The exhaust duct shouldn’t be longer than 1.5 m (5 ft.). When venting through the floor, you need to install a fan.
For upward exhaust ducts, there are no length restrictions and the following applies: The longer the duct, the stronger the stack effect.

Can exhaust air also be vented downwards?

Yes, provided that the exhaust duct isn’t longer than 1.5 m (5 ft.). If the air is vented downwards, you need to install a fan. Otherwise, the cool air below the vehicle rises up into the toilet, which would reverse the ventilation effect.
