Mosan began its work in Guatemala in 2018, developing an off-grid ecological sanitation service: a modern dry toilet and a system to safely collect and treat human excreta in densely populated, challenging environments. From the start, the goal was circular — capturing nutrients where they are harmful and returning them to the soil where they are needed, all while providing dignity and hygiene to families.
That sanitation work taught us socio-cultural awareness, pyrolysis processes, biochar formulation, and the science of nutrient recovery. Over the years the system grew into something larger: a way to transform multiple waste streams into regenerative soil solutions. The toilet was the beginning of the loop. Today we close it at landscape scale.
