 Composting Toilet 

 

SPOTLIGHT


Composting toilets rely on biological decomposition to convert humanure into a safe soil amendment.  Composting toilets use little to no water to evacuate wastes.  Material is collected in a composting chamber where it is decomposed into water vapor, carbon dioxide, and a small volume of compost that is rich in nutrients and organic matter. 

The Clivus Multrum
The Harmony House utilizes a Clivus Multrum composting toilet which has been in operation since 1990.  Humanure collects in a composting chamber located in the basement and a small amount of carbon-rich material, such as wood shavings or sawdust is added after each use.  A ventilation fan provides constant aeration of the pile and creates a negative pressure in the bathroom and basement, ensuring any odors are eliminated.  The finished compost is similar to topsoil and is used to fertilize ornamental plantings and trees. Although it could be, the finished compost is not used on any RAMC food crops as state required testing of the material is prohibitively expensive.
