Human Waste for Sustainable Futures

Photo Courtesy of Melissa Schilling Transformation has always been one of our core values – transformation of wastes into resources, of disempowered people into community advocates, of exploited landscapes into lush, productive gardens. We are a population of over seven billion people, living in a world with increasingly scarce resources. Yet, we at SOIL know that there is one resource – often overlooked – that is perpetually available: human waste. For us, human waste isn’t waste at all; it’s sustainability, it’s nutrients, its ecological power. We’ve been demonstrating the immense potential of human waste since 2006 and we don’t ...

From Larvae to Chicken Feed: What’s New with Black Soldier Fly Research

In 2019, the SOIL Research Team began testing out the possibility of using black soldier fly larvae (BSFL) as a new, additional method of transforming waste from our EkoLakay sanitation service into another valuable resource. Led by SOIL Waste-to-Resource Consultant, Michèle Heeb, SOIL experimented with BSFL at our composting site in Northern Haiti and found that our EkoLakay waste was indeed suitable for this exciting technology. The Research Team even managed to breed the flies in captivity, a prerequisite for the technology to work on a large scale. These promising results made us hopeful that this innovative waste-to-resource technology could ...

Better, Cheaper, Faster: Researching Ways to Improve SOIL’s Composting Process

Over the last six months, SOIL has made exciting and significant progress in expanding access to dignified and reliable sanitation for vulnerable communities in Haiti.  In order to continue on this upward trend, we at SOIL are working hard to produce innovative approaches to support our growth strategy to accommodate more households on the service and the additional increase in waste to treat.   To help with our strategy, we are once again partnering with Human Centered Design experts, Lukas Baumgartner and Jojo Linder, consultants from Kreativ Konsum and Kompotoi. The creative design duo, has worked with us on a number of projects to improve ...

Yale Climate Connections: As the planet warms, can we afford to treat poop as waste?

photo credit: Yale Climate Connections For centuries, people have been using human waste as a precious commodity for soil fertilization around the world. In fact, night soil, the term given to the human waste product, has had entire economies built around it as a means for sustainable agriculture production from Asia to the Amazon. A recent article in Yale Climate Connections provided some insight into understanding why we have wandered so far from these roots, how that has impacted climate change, and if it is time once again to rethink human waste as a valuable commodity. Prior to World War II, livestock manure management was an integral part of ...

SOCIETY Magazine: Completing the Poop Loop

“There is no such thing as waste; every molecule, every organism is valuable, even excrement.” – Sasha Kramer As part of a reporting program devoted supporting innovative development journalists, Grégoire Belhoste and William Thorp spent time with SOIL at our Port-au-Prince facility last year to better understand the history and process of SOIL’s regenerative urban sanitation service. The beautiful feature piece in Society Magazine explores SOIL’s history, the “poop loop” cycle, and why we believe that sanitation is a human right. Baudelaire Magloire told Society Magazine that, “we all deserve sanitation. Sanitation ...

Green America: Tackling Soil, Sanitation, and Beyond in Haiti

For a recently published feature about SOIL’s lifesaving sanitation service, Kevin Fitzpatrick of Green America interviewed SOIL Executive Director and Co-Founder Dr. Sasha Kramer about what led her to co-found SOIL, the connection between sanitation and agriculture, and the innovation behind SOIL’s revolutionary composting waste treatment facility. SOIL’s solution “addresses a wide range of basic human rights issues such as access to food, access to sanitation, and living in a clean environment.” And, as Dr. Kramer shared with Kevin, “sanitation and food are inextricably connected, both in the sense that you wouldn't poop if you ...

Training a New Generation of Sanitation Researchers

SOIL intern, Wenley Moïse, extracting samples from the liquid filters installed underneath SOIL's composting bins to take to the lab for testing. SOIL loves providing opportunities for students in Haiti to work with our team and gain valuable hands-on experience in the sanitation sector to help jumpstart their careers. Over the past six months, SOIL research partner Dr. Rebecca Ryals has been conducting a study on optimal composting conditions at our waste treatment facilities. The study looks at whether using different lining materials (concrete vs. a natural soil lining) in the composting bins impacts the leaching of nutrients or pathogens ...

Waste to Resources: SOIL’s Black Soldier Fly Research

Though SOIL’s work has undergone many iterations as we’ve carefully refined our model through the years, we have remained driven by our mission to transform waste that has such potential to do harm into resources that instead support social, economic, and environmental regeneration. As a part of this continued effort to increase the impact of SOIL’s affordable, safe, and dignified full-cycle sanitation services, a few of our team members have been working in collaboration with visiting researchers on an exciting new project at SOIL’s waste treatment site outside of Cap-Haïtien. Inspired by other members of the Container-Based Sanitation ...

Showcasing Possibility at COP24

Earlier this month, SOIL was honored to receive the United Nations' Momentum for Change Award in Planetary Health at COP24 in Katowice, Poland. Momentum for Change honors innovative and transformative solutions that address both climate change and wider economic, social and environmental challenges. Recognized as a Lighthouse Activity, SOIL’s work is honored for being a practical, scalable and replicable example of a groundbreaking intervention to tackle climate change. Check out this video showcasing the Planetary Health award winners (narrated by Sir David Attenborough!): Planetary Health: Narrated Sir David Attenborough from Momentum ...

SOIL U

Regular readers of the SOIL blog will know that in November our amazing weather station in Limonade went live, and that since that time, it has been sharing the local weather data with the world. Rainfall, temperature, wind direction and speed, pressure… it’s all there for anyone to access! Last month, the University of Limonade requested a tour of our waste treatment site so they could see the weather station and hear about how it works and what we do with the data. They were also interested in using the data in their own curriculum, as an educational tool, because weather data in Haiti can be quite difficult to obtain. Ultimately there ...
