On Climate Change Mitigation: SOIL Research Updates

As the devastating impacts of climate change continue to mount around us, especially in vulnerable frontline communities like the ones SOIL serves in Haiti, we’re more motivated than ever to grow SOIL’s climate-positive sanitation solution, which transforms a public health crisis facing cities around the world into a restorative solution for the planet. Visit this page to learn about how SOIL's regenerative sanitation service helps communities adapt to the impacts of climate change. On Mitigation: During the ecological composting process, the microbial revolution that takes place in the compost bin eliminates harmful pathogens and transforms ...

Designing Data-Driven Sanitation Solutions: An Update on SOIL’s Climate Research

As the devastating impacts of climate change continue to mount around us, especially in vulnerable frontline communities like the ones SOIL serves in Haiti, we’re more motivated than ever to grow SOIL’s climate positive sanitation solution, which transforms a public health crisis facing cities around the world into a restorative solution for the planet. To help contribute to the emerging field of study and ensure that we’re developing data-driven sanitation solutions, SOIL works in close partnership with research institutions to document and test every aspect of our work in Haiti. We believe that through SOIL's ecological sanitation and ...

New Paper Digs into Process Costs of SOIL’s Regenerative Sanitation Service

Photo: Tony Marcelli Urban sanitation interventions have historically focused on sewers or onsite sanitation options, such as pit latrines and septic tanks, but as cities are expanding at staggering rates, it’s increasingly clear that these traditional technologies are infeasible and unsafe in most urban environments. What’s also clear is that sustainability in our rapidly urbanizing world will require no less than a complete reconstruction of our cities. Instead of relying on systems that cause planetary harm, we’ll need to create ecologically regenerative infrastructure that provides needed services to urban residents while restoring a ...

Saving Water, Twenty Million Gallons at a Time

Two things we know to be true about SOIL’s crew: we’re data driven to our core and we’re really passionate about poop (or about finding innovative ways to transform it from something that wreaks havoc on the environment and public health into something that combats climate change and grows more food!) So, it won’t come to you as a surprise that our resident Composting Advisor Julie Jeliazovski decided to start tracking the number of times we were all using the restroom in SOIL’s office bathroom (aka our test lab!). She was hard at work crunching numbers to determine just how much water SOIL’s sanitation service is saving in Haiti when ...

New Research Demonstrates Safety of SOIL’s Waste Treatment Process

Photo: Vic Hinterlang SOIL is committed to fully treating 100% of the wastes from each and every household EkoLakay toilet – and we take that responsibility very seriously! Our treatment process has been developed alongside global experts and exceeds standards set by the World Health Organization for the safe treatment of human waste. Once the collected waste from the sanitation service has been treated and transformed into compost at one of SOIL’s two composting sites in Haiti, we sell the compost, Konpòs Lakay, across the country with a guarantee that it’s pathogen free. But how do we know? Ensuring Pathogenic Die Off SOIL tests ...

Monitoring Meteorology in One of the World’s Most Climate-Vulnerable Nations

Photo: Gavin McNicol A little over a year ago SOIL collaborated with scientists Rebecca Ryals (University of California, Merced) and Gavin McNicol (University of Alaska Southeast) to install a weather station at our composting facility near the northern city of Cap-Haïtien. Why a Weather Station? First, we wanted to see if local weather conditions influence the amount of greenhouse gases that are emitted during the composting process, which has been the primary focus of Becca and Gavin’s research with SOIL. We also wanted to start building a climate record for northern Haiti, a meteorologically dynamic region with sparsely available data. ...

Taking Satisfaction Seriously

Photo: Julie Jeliazovski So far this year, EkoLakay has carried out two comprehensive satisfaction surveys in order to gather quantitative and qualitative feedback on the household toilet service. We were pleased to see that customers overwhelmingly reported improved safety, health, and affordability. Despite very high overall satisfaction levels in both customer surveys in both Port-au-Prince and Cap-Haitien, a few customers in Port-au-Prince did note some issues with EkoLakay's cover material, bonzodè, which led us to look into the production protocol. Optimizing Production Protocols The Port-au-Prince EkoLakay team took this feedback ...

Is There Demand for a Better Toilet?

Photo: Vic Hinterlang We know the global sanitation system is broken. Around the world nearly 2.5 billion people lack access to a toilet of any kind and even more than that lack access to a toilet that ensures safe waste treatment. Over the past 4 years SOIL has made in-home toilets accessible to households in Haiti through our EkoLakay toilet service. What we didn’t know, and have been trying to discover, was how much people are willing to pay for a household toilet. As SOIL set out to see if we could answer that question and explore new markets for EkoLakay in Port-au-Prince, we discovered some unexpected trends in sanitation satisfaction and ...

New Research Shows SOIL’s Compost Often More Effective Than Chemical Fertilizer

Photo credit: Tony Marcelli Last June, we introduced our readers to Estrella Ardanza and Susana Perez Bejar, two Cranfield University students who have been busy studying the impact of SOIL’s Konpòs Lakay compost on native Haitian plants for their Master's theses. After months of hard work and thoughtful collaboration, we’re excited to share that the numbers have been crunched and the theses have been written. SOIL is dedicated to developing innovative and research-based ecological sanitation solutions here in Haiti and for years we’ve partnered with farmers and research institutions to study the impact of our compost on local core crops. ...

200 Pounds of Compost, Over 7,000 Kilometers and 1 Partnership

In a neat new research collaboration with implications on how we use and market compost in Haiti, SOIL is working with researchers at Cranfield University in the UK to evaluate the agricultural impact of SOIL's compost (Konpòs Lakay). This work can be summarized in numbers: 2 students will research the potential of Konpòs Lakay as part of their Master’s theses in the university’s greenhouse and laboratories. A third student will research a different kind of organic fertilizer to serve as a comparison. For this purpose, 200 pounds of SOIL's Konpòs Lakay were shipped from Port-au-Prince to Cranfield along with a few hundred Moringa ...
