Sun-mar

In The Beginning...

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.

Today...

In keeping with the family tradition, a Sundberg still leads our research and development effort. 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. Each model is designed to fill a specific need, and each is distinguished by innovative design, superior technology, and Sun-Mar's legendary quality. 

The way a Sun-Mar works is not only unique, it is also elegantly simple. Common sense tells us that the best way to compost is to use a drum. Luckily for Sun-Mar, our many international patents ensure that only Sun-Mar can take full advantage of the benefits a drum offers for mixing and aeration.
