COMPANY HISTORY

In The Beginning...

Engineering Then...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...

Engineering NowIn 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.
