Company History

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.
