In Haiti only 30% of people have access to sanitation and less than 1% of wastes are safely treated. This results in contamination of the water supply and has fueled one of the largest, most virulent cholera epidemics in recent history. While aquatic ecosystems become polluted in Haiti, soil nutrients have been rapidly declining due to erosion and intensive agricultural practices, leading to a loss of biodiversity, vulnerability to climate-related risks, reduced agricultural production, and malnutrition.
SOIL safely converts human waste to compost, transforming a public health crisis into an environmental solution. In providing sanitation services to more than 7,000 people in some of Haiti’s most vulnerable communities, SOIL is helping to prevent the spread of waterborne disease while producing 80+ tons of compost a year. Our solution is restorative by nature, simultaneously providing critical basic services, mitigating climate change, protecting ecosystems and promoting local economic growth.
Through EkoLakay, SOIL’s household toilet social business, customers pay a small, subsidized monthly fee for a locally-made EcoSan toilet in their home, which is serviced by SOIL each week. The service includes collecting full waste receptacles and replacing them with empty sanitized ones, as well as replenishing a supply of cover material (used for “flushing” a dry toilet). The receptacles are taken to SOIL’s treatment facilities where the waste is safely treated and transformed into rich, fertile compost.
SOIL will provide full waste treatment for 480 families or 2,880 people (a combined total of 2,000 households) for one year:
Production of carbon cover material
Container emptying and sanitizing
Monitoring of waste through treatment process
Sieving and bagging compost
SOIL employs 71 staff and 100 contract positions in Haiti. As SOIL’s services scale, more employment will become available in each of the neighborhoods we serve.
SOIL’s toilets are constructed from 100% locally available materials, deepening the positive impact on local economies.
40 million gallons of water saved
Up to 400% increase in crop yields
20 hectares of badly depleted land in Haiti restored
100 tons of compost produced through a process that emits 250x less methane emissions
650+ tons of waste treated
By removing waste from communities, we are reducing the spread of waterborne disease. Nearly 95% of families on SOIL’s service share their family’s health and security has improved.

The mission of Sustainable Organic Integrated Livelihoods (SOIL) is to promote dignity, health, and sustainable livelihoods through the transformation of wastes into resources. SOIL achieves this through developing social business models around ecological sanitation (EcoSan), a process in which nutrients from human wastes return to the soil rather than polluting fresh water resources.
