The Santerra Green Z Series AC Electric composting toilet system consists of an attractive ceramic low-flush toilet in the bathroom and a remote composting unit below the toilet. Unlike the Y Series from Santerra Green, the composting unit for the Z Series does not have to be directly below the bathroom (though a gravity drop is required for the flush). The included ceramic low-flush toilet uses just ½ liter of water per flush, and the entire system can support 2 additional low-flush toilets for a total of 3. Santerra Green's patented Automatic Six-Way Aeration™ system draws air through the toilet seat area on each toilet, keeping things odor-free without the need to turn the composter's drum manually. The AC Electric model is recommended whenever possible because it offers the highest capacity and performance. White.
Installation can usually be completed in just a few hours. During installation, be sure not to install any 90° bends in the vent stack. When use begins, simply add ½ cup of daily mix or similar additive per user per day to promote the natural composting process, and the system does the rest! The system will need to be emptied 1-2 times per year under normal use (see left for recommended user limits for the Z Series AC Electric model under full-time and part-time use). Single-ply or biodegradable toilet paper is recommended. Finished compost can be added to a non-food garden or buried.
