In 1971, Hardy Sundberg developed the world's first self-contained composting toilet. For the first time a self-contained toilet could be put in a bathroom and would evaporate liquids and compost solids. The next big technical breakthrough came in 1979 when Hardy develped his third generation toilet which incorporated a rotating drum as the composting chamber. This was a three chamber design which used separate chambers for composting, evaporating, and compost finishing. Now the environment for each function could be optimized individually. Sun-Mar remains the world leader in composting toilets, and dominates the North American market with its unparalleled range of 22 models from 6 different product families.
