In 1971 Hardy Sundberg of Sun-Mar™ 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 developed 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.
In keeping with the family tradition, a Sundberg still leads Sun-Mar’s™ research and development effort. Sun-Mar™ remains the world leader in composting toilets. 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™, their many international patents ensure that only Sun-Mar™ can take full advantage of the benefits a drum offers for mixing and aeration.
All Sun-Mar™ Composting Toilet Systems are certified against the "AS/NZS 1546.2:2008 On-site domestic wastewater treatment units – Waterless composting toilets" standards.
The Excel is the best-selling unit in North America and for good reason. It is a high-capacity Bio-drum toilet that is very simple to operate, features well-proven technology, and is extremely reliable. The Excel was the first ever self-contained composting toilet to be certified by the National Sanitation Foundation (NSF). So, when you purchase an Excel, you are literally purchasing a composting toilet that sets the standard.
The Sun-Mar Centrex system range is a split system, also known as an underfloor model. This means that the holding chamber is separate from the actual toilet pedestal itself. The major advantage of these systems is that they allow for greater holding capacity and therefore tend to be lower maintenance. If you have below-floor space for installation, then this is the range for you.
