Frequently asked questions

The HomeBiogas Bio-Toilet is a superior alternative to regular compost toilets. It frees you to live in a self-sustainable manner by turning your pollutant body waste into a valuable resource. Using an anaerobic system, it decomposes waste and transforms it into renewable biogas for cooking. The Bio-Toilet is easy to install, safe, hassle-free, non-pollutant, environmentally friendly, and completes a full eco-cycle in your own home with no need for outside resources.

The Bio-Toilet kit comes with all the pipes that you need to connect the toilet to the HomeBiogas system, as well as detailed instructions for assembly and attachment. You can purchase one along with the purchase of your system or you can purchase one separately and attach it to your working system later.

Important to know:

  1. Dimensions of the Bio-Toilet sitting bowl:  46W/49L/35H (cm) / 18W/19.3L/13.5H in, weighs 12.5 kg.
  2. Bio-Toilet cannot be fed with toilet paper.
  3. Distance from the system:
    – If the toilet bowl and the HomeBiogas system are at the same height: up to 5 meters.
    – If there is a 1-meter difference between the toilet bowl and the HomeBiogas system: up to 10 meters.

HomeBiogas should be placed outdoors only, in a place where it can get maximum sunlight (not in the shade), on a stable floor, free from any obstructions. On top of this, it is very important to make sure that you meet the following conditions:

  1. To have a water source close to where you intend to place the system.
  2. To keep a free 0.5 meters from each of the system’s sides for easy access.

The Bio-Toilet is a superior alternative to a compost toilet. As it takes human waste to the digester, to be digested by the bacteria to create biogas on a daily basis,  without any human contact, in a process that is very easy, efficient and clean, where minimal maintenance is required from the user, simply flush and go!

When the HomeBiogas system is fed with human waste, the effluent that comes out of the system’s outlet can not be used as a fertilizer. There are several options for the effluent’s treatment, which should all be done according to the local regulation:

  1. Connecting to the sewage system
  2. Connecting to a septic tank
  3. Treating in a drain field or mulch basin
