Sun-Mar is proud to have partnered with the Smithsonian Institute of Natural History and the CCRE to provide top-of-the-line composting toilets at their research station.
The Sun-Mar Excel NE is a premier composting toilet, intended for use where conventional power is not available or will be intermittent. It is a high capacity, self-contained system that turns waste into usable compost. It does not require water access or a septic, which made it ideal for the remote location of the CCRE’s field station.
The Excel is Sun-Mar’s best selling self-contained composting toilet in North America, and for good reason. It is a high capacity Bio-drum™ toilet that is simple to operate, features proven technology and is extremely reliable. The Excel was the first ever self-contained toilet to be certified by the National Sanitation Foundation (NSF). So, when you purchase an Excel for your cabin in the woods or your luxurious bathroom, you are purchasing a composting toilet that sets the standard.
Sleek and elegant, the GTG is Sun-Mar’s smallest and most economical composting toilet ever. Whether you’re installing it in a beach front house or treehouse in the woods, the GTG goes anywhere. As the pioneer and category leader in composting and separating toilets, this toilet further extends Sun-Mar’s innovation, leadership and bold designs.
The Centrex 2000 is one of Sun-Mar’s high-capacity composting toilet systems. It allows for both a longer composting cycle, can support larger waste volumes than the self-contained models, and is perfect for both residential use in your home and vacation use in your cottage by the sea.
