Compost Away your Stinky Toilet!

I know when I usually go to the bathroom, there is potential to smell up the entire place and cause quite a stink. However, there is a new product on the market that could reduce that nasty odor and help save the environment. The Sun-Mar composting toilet is a new invention that will help homeowners and businesses save 27 percent on their water bills. It could be the ultimate for charter buses, RVs and rural homes to stop the lingering smell of poop in the air.

Sun-Mar Composting Toilet

The innovative lavatory requires no plumbing, local sewage connection or septic system. It works by evaporating urine and composting solid waste without any ground water being needed or being contaminated. The alternative to conventional toilets also uses organic processes to convert the waste into a safe fertilizing soil. The Sun-Mar toilet uses a very unique system to decompose the waste in a clean and efficient manner. It uses a distinct three-chamber system, which includes a patented drum

technology—called a Bio-drum—which speeds up the breakdown of human waste and toilet paper. The three-chamber technology also has a section for evaporating urine and a finishing drawer to remove the sanitized compost. Instead of flushing, toilet owners place inexpensive chemical-free bulking material to the drum chamber to fast-track the breakdown of nutrients in the human waste. It then periodically uses a handle to freshen the waste while being mixed. The waste should be dumped outside, preferably in a garden, but it only needs to be done a few times of year.

The Sun-Mar composting toilet is designed for air to be constantly circulating through the toilet so that there would be as little smell as possible. The innovative piece of equipment has been certified for residential and cottage use by the National Sanitation Foundation. Fraser Sneddon, Manager of Sun-Mar Corp., said that getting rid of an odor is a challenge with composting toilets, but that it isn’t a problem with the innovative green technology. “Many people tend to feel uncomfortable about the idea of composting their own waste, which often conjures up images of smelly outhouses or compost heaps in the garden, but Sun-Mar’s product eradicates that notion because it’s so easy to install and effortless to operate, creating a sanitary and odor-free environment,” Sneddon said.

    what is this bulking material?

    I don’t trust toilets like that. How is it to be utilized? What if I fell on it, will it turn over? As for me, I try to keep my “rest room” clean, and I have no odors there at all, but of freshener.

    Before anyone gets too excited about composting toilets, they should get the right information. I bought SunMar toilet, and found their installation and operation manual missing crucial information.
    Our system is designed for daily use by up to two individuals, which we are.
    1. We had no idea that the urine will accumulate, with limited evaporation – so we connected the overflow to our drain (probably against municipal regulations). Since we started in January (indoors, minimum temperature about 12 degrees Celsius), we blamed the lack of evaporation on low temperature and poor airflow. We then installed a 12V fan into the venting system to improve the evaporation.

    It is mid-July, and the drain overflow (because of necessary slight rise in the piping) is full and the urine overflowed in the wrong direction, into the floor of the front “finishing” drawer. So where is the excess urine supposed to go?

    We used quantities of the bulking agent to soak the stuff up – in the end about 2 bags. Because it was too cold when we started, we did not add solid waste to the system yet, fearing slow composting.

    2. In May, the toilet became a breeding ground for small flies, which seem to be drawn to light and accumulate at our windows. Dumping insecticide into the drum may be an option – net very green one, though. Broad action insecticidal toxins like rotenone may also inhibit bacterial composting. Any suggestions on what to use?

    3. I cleaned the system out (I hope adequately) to get rid of the flies and excess urine. As the temperature in the addition is about 20C and after I reinforce the floor insulation it will be about 15C during winter, I will re-start the system.

    Any advice on what to do better in the future will be appreciated.

    My advice is not to use such systems at all! My dad had one of them and it’s clear mess((
    very uncomfortable he says..
    I believe him. I use stationary toilet only, ordinary one. And I have no problems with air and smells.
    Like Body said keep it clean and you’ll be ok!

    Thank you for your comments. The non-electric toilet evaporation is completely dependent on the environment that the unit is installed in, so therefore, the overflow drain is necessary. This drain is gravity fed so must slope downwards at all points. The liquid exiting is not under pressure so will not flow if the drain hose is higher than the liquid. Also, all composting toilets need temperatures above 13°C. Below this temperature, microbes will go dormant and the composting process will slow or stop. Please call Sun-Mar toll free 1-888-341-0782 for more information on how to manage your toilet. We do want you to be happy with your purchase.

    My bathroom always smells very badly in the entire home. The new invention of Sun-Mar composting toilet is really helpful for us as well as our environment because in this no requirement of water and plumbing. It uses a very different technique for decomposing the waste from other conventional toilets.

    So on occasion, when a human is sick, how is diarrhea handled? For instance, many times liquidy feces is evacuated from the body forcefully and will splash all over inside a toilet bowl. What is the cleaning method for this situation? I’m sure these toilets are in the range of $2,000 so not a ‘throw-away’ investment. Disgusting issue but one very relative to the conversation.
    Thanks for any input.
