How Composting Toilets work.

  1. Composting toilets use nature's decomposition process to reduce waste by 90% and convert it into nutrient rich compost.
  2. They do not require water hook ups either which is great for our already stressed water supply. In short, composting toilets are a way to allow waste to decompose safely and without odors.
  3. Composting toilets use oxygen loving bacteria that is naturally present in human waste to do all the work.
  4. Bugs, worms, and other critters have absolutely NO role in BioLet's composting process.
  5. You just use a BioLet like you would a regular toilet, toilet tissue and all. The main difference is you just toss in compost mix after each fecal use instead of flushing. The air flow inside the toilet pulls all odors up the 'chimney' and out of your home.
  6. Composting reduces waste volume by 90%; the majority of the material inside the toilet is mulch and not waste. You do not even have to see it with the way BioLet is designed. Yes, you do have to empty the lower compost tray periodically, depending on how many people are using the toilet, but it is only compost, soil. There is no waste mixed in the tray.

How Electric Biolets work 

( BioLet 10 Standard, BioLet 20 DeluxeBioLet 60 XL,)

When you raise the upper seat on the toilet you will see a "clam shell" cover called the compost cover. This hides any waste from view and automatically opens when the seat is depressed allowing the waste to be Assembly of a BioLetsafely deposited into the compost chamber below.

Inside the compost chamber is BioLet Starter Mix with a base of peat moss and pine wood shaving. After use, a small amount of BioLet Starter Mix is added to the toilet and the upper seat is lowered. A mixer automatically starts to turn mixing the waste with the BioLet Starter Mix and aerating the material already inside the chamber. This process creates a mixture with all the components required to induce aerobic decomposition (carbon, nitrogen, oxygen and moisture). An electric fan located in the back of the toilet continuously draws air into the toilet, through the seat, preventing any odors from escaping.

This air is circulated throughout the composting chamber by BioLet's patented air recirculation process, allowing for maximum absorption of oxygen by the material inside the toilet. The more oxygen that is supplied to the aerobic bacteria, the more thoroughly and faster the waste will be transformed into humus. As the air is circulated through the unit, it is heated by a thermostatically controlled heater.

The heated air evaporates the liquids in the toilet keeping the material inside at the proper moisture / carbon / nitrogen ratio for optimum decomposition. The moisture latent air is then vented to the outside through a vent pipe running from the toilet to the outside of the structure where the toilet is housed. As usage continues the "material" will continue to build up inside the composting chamber.

Internal workings of a BioLetWhen it reaches the upper leveling arm, it's time to empty the tray in the bottom of the unit (once every 2 months to a year, on average, depending on usage). Simply remove the thumbscrews from the door on the front of the unit, slide the tray out, and empty the dry, nutrient rich, ODORLESS humus. The humus can be leached into the soil around decorative plants or disposed of in an ordinary trash receptacle.

How Biolet NE works

If reliable power supply is not an option, the BioLet 30 NE is the way to go. Using a process called batch composting, the BioLet 30 NE can handle a high volume of usage. Batch composting is a process where you make a batch of material then remove it from service so the material can compost without anything new being added to it.

The BioLet 30 NE has a compost cover and ventilation pipes described in the above models, but it works by applying a very different approach. A large compost bin is housed inside the lower portion of the toilet. The toilet is used until the bin is approximately 3/4 full. The top of the toilet is then removed and the bin is removed from the unit and moved outside for further composing.  A secondary bin is then placed into the unit for continued operation.

Air circulation through the unit occurs due to the natural convection of air through the ventilation pipe. This is induced by the heat that is produced by the composting process, temperature differentials between the inside and outside of the structure, and by the natural chimney effect created by the vent pipe. Installing an optional 12VDC fan into the vent pipe can induce additional circulation of air and increase the capacity of the unit.
