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. As water sources are increasingly polluted from untreated human waste, soil nutrients have been declining rapidly, leading to loss of biodiversity, extreme vulnerability to climate-related risks, reduced agricultural productivity, poverty 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 9,000 people in underserved communities in Haiti, SOIL is helping to prevent the spread of waterborne disease while producing 100+ tons of compost a year. SOIL is demonstrating it's possible to provide a solution that simultaneously restores ecosystems, creates jobs, protects public health and mitigates climate change.
Through EkoLakay, SOIL’s household toilet service 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.
World Centric provided 15% of the total cost for SOIL's waste treatment program, which provides services for 1,511 households or 9,000 people for one year:
Production of carbon cover material
Container emptying and sanitizing
Monitoring of waste through treatment process
Sieving and bagging compost
Construction of new compost bins
Infrastructure support activities
SOIL employs 52 staff and 100 contract positions in Haiti.
SOIL’s toilets are constructed from 100% locally available materials, deepening the positive impact on local economies.
Water conservation using waterless CBS technology
100+ tons of compost produced
Restoration of 30 hectares of badly depleted land
400% increase in agriculture yields using SOIL’s compost
Climate change mitigation of 126kg CO2 equivalents per capita per year
By removing waste from communities, SOIL is 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.
