Composting Toilets


(C) Copyright: City Farmer

Information on the use of composting toilets in cities is not easy to find. Building and plumbing codes don't encourage installation. Compost toilet systems are more common in parks, roadside facilities and vacation homes.


City Farmer has a Compost Toilet!
"But how do we use it", the staff wanted to know? "There's no water in the bowl, no handle for flushing. What can we throw in it, how do we keep track of how much human waste goes in, and what words should we use to describe our waste?"


Sun-Mar Composting Toilets. Zero environmental impact. Use no water. Works with nature to produce fertilizer and evaporate liquids. Useful in cottages, cabins, pool cabanas, residences.

The C.K. Choi Building
at The University of British Columbia

Institute of Asian Research

In Vancouver, British Columbia, a 30,000 sq. ft. office complex, utilizes composting toilets and urinals for human waste disposal. The new building, which houses The Institute of Asian Research, is not connected to the city's sewer system. As well, a subsurface, greywater recycling system with phragmite (tall grasses) plant varieties, cleanses the greywater which is then used for on-site irrigation.

The C K Choi Building at UBC is the first all-Clivus Multrum large-scale office-building project in Canada.

There are a total of 5 Clivus Multrum Model M28 Composters at the Choi Building...with ten flushless toilets and, in addition, several flushless, trapless ventilated urinals attached to them. Each of these Clivus Composters has an annually user capacity rated at 45,000 visits. Therefore, the total annual rated capacity for the Clivus systems there is 225,000 visits. All of the Choi building's washwater (greywater) is processed on-site separately.

"Despite all of the knowledge humankind has accumulated in the past 10,000 years, we still do not know fully how to use our urine and manure to fertilize our farmlands in a way that is simple and efficient, will not spread disease, and will benefit the soil. This knowledge is increasingly important as soils continue to lose the minerals and organic matter they need to remain fertile. Discovering how to utilize our waste as fertilizer is the challenge we must meet if our farmlands are to continue to provide us with food."

Appalachian Trail Conference/Green Mountain Club Backcountry Sanitation Manual
Pete Antos-Ketcham and Richard Andrews authored and edited the Appalachian Trail Conference/Green Mountain Club Backcountry Sanitation Manual in 2001. It is an online PDF manual that features information on several owner-built and commercially made composting toilet systems that are being used to manage human waste at high use campsites on the Long Trail and Appalachian Trail. This manual and the systems would be of interest to those who want to manage sewage in the frontcountry or the backcountry.
