Windrow Composting: What We’ve Learned from the Pilot Research and Where We’re Going

Over the past year, the SOIL research team began experimenting with windrow composting, as a method for making our waste treatment and composting process faster. The goal of the research was to improve the efficiency of the composting process in order to be able to accommodate more waste at our site, as well as decrease operational costs. After months of trials, we are excited to share our latest update on the research!   What’s Windrow Composting? Windrow composting involves emptying containers of waste (and bagasse) collected from households on SOIL’s service into a pile on the ground (and elongating it into a row) as an alternative to the ...

Farmers Driving Increase in Compost Sales in Cap-Haitien

SOIL’s compost team working at compost site Over the past year, SOIL has produced 170 metric tons of our rich, organic compost at our waste treatment facility in Mouchinette, Haiti. Extensive research shows that not only does compost increase agricultural harvests, but compost application can also be instrumental in restoring ecosystems and mitigating against the impacts of climate change through increased soil water retention, restoration, and carbon sequestration. This means that with every sack of compost that SOIL sells, Haiti is becoming a little more resilient to droughts, floods that wash away topsoil, climate change, and food insecurity. ...

How Ecological Sanitation Can Promote Food Security

SOIL team member planting with Konpós Lakay Here at SOIL, we’re dedicated to basing our strategic objectives and design iterations on careful research and data. We’re also committed to sharing our lessons learned, and progress with the global ecological sanitation community. We’re pleased to share a recent publication in partnership with the University of California, the University of Hawaii, and the University of Vermont in the Frontiers Sustainable Food Systems Journal. “Toward Zero Hunger Through Coupled Ecological Sanitation-Agriculture Systems” explores the potential of ecological sanitation (EcoSan) systems to transform nutrient ...

Sharing Our Story with Carel Pedre

Carel Pedre speaking with SOIL's Senior Manager, Romel Toussaint In recent weeks, there has been a sudden flurry of interest in the value of human waste in the Haitian media, leading to increased attention, and sometimes head-scratching speculation, as to the ins and outs of SOIL’s work. SOIL was delighted at this new peak in interest and wanted to use this as an opportunity to answer some of the questions that were being asked with regard to SOIL’s work with waste - and exactly what we were doing with that waste! In order to share more of the real story about our innovative sanitation solution, SOIL reached out to renowned Haitian journalist and ...

The Potential of Human Waste: SOIL Featured in Newswise

Compost team pictured with SOIL’s organic, agriculture-grade compost made from human waste. Our world creates an enormous amount of waste, and that waste exists in many, many different forms. There’s food waste, liquid waste, hazardous waste, solid waste, and what we at SOIL care most about, human waste. A recent article published in Newswise, titled (Human) waste not, want not, highlights the topics discussed in a presentation by Rebecca Nelson, Cornell University, at the 2021 ASA, CSSA and SSSA Annual Meeting on a new vision for the reuse of human waste. Nelson, a plant pathologist, shares a sentiment on the incredible and largely untapped ...

Improving Customer Satisfaction: From Design to Large Scale Production

EkoLakay toilet with new urine diverter Research plays a critical role in SOIL’s efforts to achieve strategic goals and advance knowledge in the sanitation sector. The Research team is also actively engaged in projects that aim to improve toilet design to better meet the needs of customers and ensure customer satisfaction across the entire sanitation chain. To do this, we regularly gather customer feedback to improve product quality and ensure a design that meets the needs of all users. Since 2015, the Research team has been testing new urine diverters for our container-based toilets, and the design is finally ready for large-scale production! ...

Exciting Updates from SOIL’s Black Soldier Fly Research

Last summer, SOIL began an experiment that evaluated the potential of another waste to resource technology at our compost site: flies! The study looked at breeding black soldier fly (BSF) larvae for use as chicken feed. The goal of the research was to determine whether we could successfully grow BSF larvae, which feed on waste, at our Cap-Haïtien waste treatment site. If successful, the production of BSF larvae to sell as chicken feed could become an additional stream of revenue for SOIL’s waste treatment operations. The research, led by SOIL Research Associate Michèle Heeb in partnership with visiting researcher Dani Peguero, has already ...
