Abraham Noe-Hays has been working with dry sanitation systems since 1990. He holds a B.A. in Human Ecology–with concentrations in agroecology and compost science–from the College of the Atlantic, where his interest in recycling human manure led to an internship at Woods End Research Laboratory and his thesis project, “An Experiment in Thermophilic Composting Toilet Design.” He has operated Full Circle Compost Consulting since 2001, providing complete design, manufacture, and maintenance services to individuals and institutions with dry toilet systems. He is also the eco-sanitation expert for Sustainable Harvest International, and has helped SHI initiate urine-diversion projects in Nicaragua, Honduras, and Belize. In addition to hands-on dry sanitation work, Abraham gives lectures and leads workshops at conferences and schools, and writes articles on the topic.

Kim Nace holds an M.A. in International Administration from World Learning and an M.A. in Educational Leadership from Keene State College. She was a Peace Corps volunteer in Botswana and has taught children of all ages. She coordinated research funded by the MacArthur Foundation and later served as an Elementary School Principal – at Central School in rural Vermont and the American International School in Chennai, India. She has been passionate about sustainable sanitation alternatives ever since creating an educational video about composing toilets for her 1989 master’s thesis project, along with her husband, Mike Earley. Now she is pleased to again be engaging others in the possibilities and practicalities of human manure recycling at the Rich Earth Institute. Kim and her family use a urine diverting composting toilet.
