Only 34% of families living in urban Haiti have access to improved sanitation. As a result, Haiti has the highest rate of childhood diarrhea in the world. As water sources are polluted from human waste, soil nutrients are declining rapidly, contributing to malnutrition. In Haiti, the cycle of poor sanitation, environmental degradation, and poverty are devastating for communities and the environment alike.



SOIL's lifesaving sanitation service is tackling one of the world's toughest challenges with a groundbreaking environmental solution. SOIL provides families in Haiti with household toilets, waste collection, and safe treatment and transformation of wastes into agricultural-grade compost. Our solution is demonstrating that it is possible to simultaneously restore soil health, save water, create jobs, stop the spread of disease, grow more food, and mitigate climate change.

Target Beneficiaries

SOIL’s primary beneficiaries are urban residents without access to safe, dignified sanitation. This beneficiary group is comprised of families living in impoverished urban and peri-urban neighborhoods in Port-au-Prince and Cap-Haïtien, Haiti where traditional sanitation technologies have proved impossible to implement. Secondary beneficiaries include farmers who use the compost and people living in environmentally degraded areas where reforestation efforts are underway.

Mission and Vision

SOIL's mission is to promote dignity, health, and sustainable livelihoods through the transformation of wastes into resources. Our development model was created as a response to the community-identified priorities of increasing access to sanitation, improving food security, creating jobs, and building a healthier living environment. SOIL is ultimately committed to designing open-source solutions that can be scaled and replicated in Haiti and around the globe.

Innovation Description

SOIL’s circular sanitation system is low-cost, avoids reliance on energy and water, safely contains and treats waste, and offers valuable resource recovery. The service is comprised of the following elements:

Toilet Manufacture– SOIL’s toilet is manufactured in Haiti by local contractors, many of whom are women.

Toilet Installation– New customers to SOIL’s sanitation service receive a composting toilet and customer education on the topics of hygiene, how to use and maintain the toilet, and how to use the service.

Toilet Servicing– SOIL Collectors visit customers weekly to deliver sanitized empty containers and carbon cover material that serves as the “flush” in the dry toilets, and take the full containers of waste to a transfer station where they are then transported to SOIL’s waste treatment facility.

Container Emptying– The waste is emptied into compost bins and covered with sugarcane bagasse. The containers are then washed with a chlorine solution and returned for reuse in our service.

Treatment & Transformation– The composting process uses the power of ecological processes rather than energy to safely treat waste. After a treatment period of six to nine months,the compost is tested for pathogens, sieved and bagged for sale.

Compost Application– Unlike chemical fertilizers, SOIL’s compost restores soil structure to increase yields year-after-year, improves drought tolerance, and increases root growth for long-term plant health and soil carbon sequestration.

Competitive Advantage

SOIL’s initiative is one of the most promising tests of the paradigm-shifting hypothesis that sanitation no longer needs to focus on the linear model of waste disposal, but rather on the ecologically beneficial reuse of human waste. With nature as our inspiration, SOIL designed an innovative sanitation system that simultaneously restores the environment to its life-giving potential, prevents the spread of waterborne disease, creates jobs, saves water, and emits less greenhouse gasses than traditional sanitation technologies. Nutrients that would have otherwise leaked into the water, the atmosphere, or ended up in landfills are safely returned to the soil. SOIL’s solution has proved resilient in one of the most uniquely challenging and high-risk environments, charting a pathway for safe sanitation services in resource-poor urban settlements globally.

Planned Goals and Milestones

The global urban population is projected to increase by 2.5 billion people by 2050, with much of that growth concentrated in regions vulnerable to the impacts of the climate crisis. While SOIL is first committed to scaling sanitation services to support public health outcomes and economic development in Haiti, we seek to prove that it is possible to affordably and sustainably provide safe sanitation services even in some of the world’s most impoverished and resource-scarce urban communities.
