How the BioLet 10 Standard Works

BioLet Composting Toilets use the natural processes of evaporation and aerobic decomposition to transform human waste into a nutrient rich hygienically safe product called "humus".

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 safely 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. You then turn a T-handle on the top of the unit a couple of times 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. When 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.
