Using Waste To Move Waste

Mark Illian of Nature Healing Nature in the U.S. will work with villagers in rural Africa to design a pour-flush latrine utilizing readily available urine instead of scarce water for flushing, and drops of used cooking oil for odor control. Achieving a successful design of these latrines could stimulate more latrine building to reduce open defecation and resulting diarrheal diseases.
