When deciding which treatment solution is best for you it is very important to understand how various systems compare. Most waste treatment systems rely on bacteria to breakdown organic waste. This process is known as composting. Traditional systems typically rely on a type of bacteria that survives in the absence of oxygen (anaerobic bacteria). Anaerobic bacteria work very slowly at breaking down waste and produce very foul odors (sewer gases). Sun-Mar units are engineered to support a type of bacteria that requires oxygen to survive, aerobic bacteria, which work very quickly at breaking down waste and produce no odor. This allows Sun-Mar units to be much smaller and more cost effective than traditional systems. Whether the treatment system supports aerobic or anaerobic bacteria, it is extremely important to choose a system which fully composts waste to protect public health and safety. Quite often companies will use the term composting to describe their systems, although they do not fully compost waste. This is particularly true of urine separating toilets which merely collect waste or provide only partial treatment. These systems leave the homeowners with the daunting task of regularly having to dispose of raw solid and liquid waste. Fully composting waste is very important for public health & safety and the environment. This is why comprehensive evaluation and certification by NSF International, a Public Health and Safety Organization, is crucial. It ensures products perform as claimed and meet strict public health standards for design and performance. Although ANSI/NSF standard 41 has been around for over 25 years, Sun-Mar is one of only 2 companies certified and listed by NSF international. Many regulators require this certification.
