How do I get a permit for a composting toilet?
NSF/ANSI 41 certified – NSF is a US based public health and safety organization that creates standards and tests products to see if they meet those standards. NSF Standard 41 is a standard developed in the 1970s for composting toilets it tests both the product and does an evaluation of the manufacturing facility.
What composting toilets do you personally recommend?
Greywater Action’s Composting Toilet FAQ has a thoughtful answer to this and other technical composting toilet questions. The Cape Cod Eco-Toilet Center is another great resource that reviews a wide variety of toilets.
How do I make sure my compost is safe for use in my garden?
Compost from toilets should undergo fecal coliform and moisture content testing to ensure safety, the same biological testing that NSF-certified manufactured composting toilets must undergo. Testing depends on the lab, but usually costs between $35-70. Oregon State provides a useful list of soil testing facilities that serve Oregon.
