Back to the Basics: An Overview of SOIL’s Essential Service

Readers of our blog might know that SOIL provides EkoLakay sanitation services to households in the city of Cap-Haïtien on Haiti’s northern coast and that we are currently providing this essential service to nearly 2,000 households, impacting over 11,000 individuals. This past year alone, our sanitation and composting staff collected and treated over 500 metric tons of waste from the communities we serve and produced 170 metric tons of compost through our ecological waste treatment process. But do you know how the service works?  For new potential household customers, the EkoLakay journey begins when an individual expresses interest in ...

Breeding in Progress: Updates on SOIL’s BSFL Research

SOIL's black soldier fly rearing unit containers, provided in partnership with USAID.  In 2019, the SOIL Research Team began testing out the possibility of using black soldier fly larvae (BSFL) as a method of transforming waste from our EkoLakay sanitation service into protein-rich larvae that can serve as animal feed. This technology can be used in combination with the existing composting process. After a delay in our pilot trials due to the Covid-19 pandemic, work resumed last year on the project, in partnership with USAID Haiti, and we have a few exciting updates to share.  Black soldier flies (BSF) are endemic to Haiti and wild ones have ...

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. ...

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 ...
