Mosan began in 2018 in Guatemala, developing an off-grid ecological sanitation service: a moderndry 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.
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, and to connect this system with global supply chains. The toilet was the beginning of the loop. Today we close it at landscape scale.
