SOIL promotes dignity, health, and sustainable livelihoods through the transformation of wastes into resources. SOIL pilots sanitation social business models in Haiti, where only 25% of people have access to a toilet (globally 2.5 billion lack access to improved sanitation). The lack of safe, dignified toilets that work in conjunction with affordable waste treatment options not only results in contamination of water supplies with dangerous pathogens, it also represents a significant loss of nutrients and organic matter that could be used to improve soil quality. SOIL’s work in addressing this crisis is unique in that it is one of the largest and most promising tests of the paradigm-shifting hypothesis that sanitation no longer needs to focus on waste disposal, but rather on transformation, allowing for the profitable capture and reuse of nutrients found in human waste.
