About SOIL

SOIL is a non-profit research and development organization working in Haiti to design, test, and implement sustainable and cost-effective solutions to the sanitation crisis. SOIL focuses on pioneering approaches to sustainable sanitation service delivery that combine innovative service delivery models and new technologies with a strategic, catalytic approach to financial sustainability.

They are demonstrating that it’s possible to provide safe, affordable sanitation access to people living in even the world’s most vulnerable urban communities.

SOIL Mission

The world is experiencing an unprecedented sanitation crisis with more than half of the world’s population lacking access to a toilet that safely manages human waste. In Haiti, only 30% of the population has access to improved sanitation and less than 1% of wastes are safely treated, which has fueled one of the largest and most virulent cholera epidemics in recent global history.

While aquatic ecosystems become increasingly polluted with nutrients from human waste, the earth’s soil nutrients have been rapidly declining due to erosion and intensive agricultural practices, leading to a loss of biodiversity, extreme vulnerability to climate-related risks, reduced agricultural production, poverty, and malnutrition. As cities expand at staggering rates, it’s critical that the sanitation sector develops innovative approaches that work in dense urban areas to avoid exacerbating the toll of preventable waterborne disease.

SOIL provides full-cycle sanitation services from containment to reuse by taking a circular economy approach.

By providing toilets and removing waste from communities, SOIL is preventing the spread of waterborne disease, increasing families’ safety and security, and protecting vulnerable aquatic ecosystems.

SOIL then safely treats the collected waste and transforms it into compost which is sold to support agriculture, reforestation, and climate change mitigation efforts in Haiti.

Dignified, sustainable, safely-managed sanitation which optimizes resource recovery and is accessible to all.
