FAQ’s
-
How does it work?
It’s very simple: all you need to do is to flush the waste down the Bio-toilet. The waste then goes through the waste pipes into the system, where the anaerobic bacteria break it down into biogas for clean cooking and effluent for further treatment in mulch basin/ septic or sewage. (following local regulation)
-
Can I place the Bio-toilet in my tiny house?
Yes! As long as it is within the right distance from the system.
-
How many flushes can I feed with?
Depends on the system you have. Start with 25 flushes for HomeBiogas 2 and up to 75 for HomeBiogas 6.
-
Do I need to separate waste?
No, it is not necessary.
-
Should I use on a daily basis?
You can feed whenever you want, you can miss days. The system is designed to provide biogas only when you feed.
-
How much water does it take per flush?
The Biotoilet takes 1.2L per flush, but may vary as each “slight” pump uses only 300 ml of water.
-
Can I connect to a regular toilet?
No! Both in term of design and water use.
-
How do I separate urine?
No need to separate urine! HomeBiogas Bio-toilet is very easy to use and all you need to do is flush your toilet.

Once every 6 months, you’ll need to replace the gas filter.
-
How do I clean my toilet?
Water, vinegar and ecological cleaners only! Do not use chemicals as it will kill the bacteria.
-
Does it smell?
One of the greatest advantages of the Bio-Toilet is that it’s odorless.
-
How hard is it to build the mulch basin?
Super easy! All you need is a small field, filled with mulch and topped with soil. For the dimensions, please see the Bio-toilet manuals and this installation video.
-
How often is the effluent produced?
The effluent flows continuously with every flush.
-
How do I treat the effluent?
There are 3 options to treat the effluent: (1) building an off grid mulch basin or drain field. (2) connecting the system’s outlet to the septic (3) connecting the system’s oulet to the sewage Please note that you’ll need to follow according to your local regulation on any of the 3 options mentioned above. HomeBiogas’s recommendation is 1 – a mulch basin or drain field.
-
Can I use the effluent in my garden?
The effluent that is released from the system’s outlet requires further treatment and can not be used on edible plants.
-
Where should I install the water heater?
The water heater should be installed in an open and sheltered area. If you are installing it in a well-ventilated indoor location, we recommend purchasing a 90 mm (3.5 inch) diameter chimney. The chimney should be installed according to local regulations. A general guideline would be an upward slope and a maximum length of 2m.
-
Can I put the Bio-toilet indoors?
You can put it anywhere you want as long as it is within the right distance from the system?
-
How far can the toilet be from the system?
If the toilet and system are the same height, then the distance between the two can be up to 5m/16 ft. If the toilet is 1m higher than the distance between the two, the distance can be up to 10m/32ft.

-
Can I use the system during a freeze?
We do not recommend using HomeBiogas at or below freezing points.
-
What is the right temperature?
HomeBiogas loves warmer climates. With that being said, human waste doesn’t require lots of energy to breakdown, therefore a minimum temperature of 41F/ 5C is needed. (gas may not accumulate below 50F, but we do have a solution for that — the HomeBiogas booster kit! )
-
Is HomeBiogas a safe product?
HomeBiogas is a safe product for the following reasons: (1) the biogas is uncompressed (2) stored at low pressure (3) its on top of thousands of liters of water so in case it catches fire it will be turned off rapidly (4) Biogas is a lightweight gas, so in case it leaks it will move upwards pausing no health risk.

Since it does not release smells it won’t attract animals. However, if you think an animal might cause damage to the system, we recommend placing it in a greenhouse or adding fences around the system.

Will HomeBiogas explode?
Short answer no. Long answer: The biogas that is created in the system is uncompressed and is stored at low pressure which makes it very hard for the biogas to explode. HomeBiogas is also ISO certified.
