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.
