How Composting WorksComposting is Nature's WayEvery living organism consumes nutrients and creates waste. To transform waste back to nutrients and complete this cycle, nature uses the processes of decompostition and evaporation. Sun-Mar toilets are designed not only to harness these natural processes, but to optimize and accelerate them. Toilet waste is over 90% water content. This can be evaporated and the small amount of remaining material is recycled into a useful fertilizing soil. Sun-Mar units are economical, quick to install and easy to use and because no chemicals nor septic systems are used, fragile environments can be protected. A Sun-Mar composting unit is an environmentally healthy choice for recycling human waste. And there's no smell!The Sun-Mar system evaporates excess liquid and by continuously pulling air in it ensures no smell escapes from the unit. ENVIRONMENTAL BENEFITSBy using a Sun-Mar composting toilet you are doing your environment a huge favor.

Sun-Mar Self-Contained Composting ToiletExcelThe 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 Excel has enough capacity that it can be used just about anywhere: in residences, cottages and even in light commercial applications. To simulate residential use the Excel was tested by the NSF at maximum capacity for 6 continuous months, during which the Excel produced no odour and produced a clean, safe compost. Only Sun-Mar self-contained units are listed for residential and cottage use by NSF, whose Standard #41 is the toughest composting performance standard in the world. The 2" vent is attached at the top back of the Excel and can be installed invisibly by running it through the wall and up the outside wall. For comfort the Excel has a sturdy detachable footrest which can be removed to pull out the finishing drawer. In normal use the Excel can normally evaporate all liquids, however a ½" emergency drain is fitted at the rear and this should be connected if the unit is to be used residentially or heavily, or if prolonged power outages are expected. CompactThe Compact is an elegant low profile unit with the looks to complement any bathroom. Sun-Mar engineers designed this low profile toilet by developing and patenting a new variable diameter Bio-drum which is small at the front and large at the rear. To maintain the uninterrupted lines of the Compact, a patented Bio-drum handle recesses into the body of the unit to mix and aerate the compost. The Compact differs from the Excel in that all three chambers are smaller, which makes the Compact ideally suited to light residential or light to medium cottage use. As with the Excel, a 2" vent stack attaches to the rear of the Compact. A 1/2" emergency drain at the rear offers protection against heavy or residential use, or prolonged power outage. Excel NEThe success of the Excel design meant that a three chamber unit could be specifically designed for those with NO continuous 110 volt supply. First launched in 1981, the Excel NE has long been the standard toilet for those living off the grid. A 1998 redesign gave the unit a rounded look, and recessed the drum handle. The Excel NE has no fan or heater. Odorless operation is achieved by a 4" vent mounted at the top rear of the unit which acts like a chimney on a wood stove. For good air movement the vent should be installed vertically and to 2-3 feet above the peak of the roof. The optional 12 Volt Fan should be installed if you need to install the toilet with any bends in the vent. No more than 2 45° bends are encouraged, even with the fan. If the Excel NE is used residentially or heavily, or is in a place which is subject to downdraft, the optional 12 volt fan should be installed in the vent stack. This fan draws 1.4 watts and can be powered by a solar panel and 12 volt marine battery. Evaporating capacity on the Excel NE is variable, so the 1" drain at the rear should be connected to an approved drain pit, container, or other facility.
