In 1972, Sture Andersson founded the original company in Sweden. His vision was to manufacture the most convenient waterless composting toilets in order to give customers a real alternative to regular flush toilets. The first model was called MullToa meaning composting toilet in Swedish. The MullToa fast became a wide-spread toilet alternative in Scandinavia. His idea to offer the best designed waterless composting toilet spread around the globe and by the mid 1980s MullToa and BioLet - its international brand name - were being patented and sold in over 30 countries.

How do BioLet Composting Toilets Work?

BioLet unites the natural composting process with advanced technology accelerating and optimizing biological decomposition, evaporating excess liquid and exhausting odors… all within an elegant bathroom fixture that is easy to use and economical to operate.


The closed-system BioLet toilets are fully automatic electric toilets that anticipate your every move! Sitting on the toilet seat opens the trap doors; closing the toilet seat lid activates the stainless steel mixing mechanism that efficiently breaks down paper and distributes moisture into the compost material in the upper chamber. Material in the upper chamber is finished in the lower chamber and eventually emptied. The BioLet 65 features LED maintenance indicators to let you know when it is time to empty the lower chamber. The non-composted portion and the dry, composted portion are kept separate.

A fan circulates warm air under and around the compost for fast decomposition and evaporation of liquid. A float switch operates an additional bottom heater if excess liquid is detected. Once a week or as needed, mulch is added through the toilet seat opening.

Using efficient Swedish technology, electrical consumption is very low with an adjustable thermostat, which is set according to the number of people using the toilet. When you are away for more than two days, just turn off your BioLet!
