The Mosan Circular System decontaminates the environment and transforms organic waste streams and biomass — dried sludge, coconut shells and coffee pulp— into enriched biochar substrates that rebuild degraded soils, increase biodiversity, and permanently store carbon. Climate-positive circular systems, starting in Guatemala.
We are determined to reduce contamination, close nutrient cycles, and enable regeneration — by capturing nutrients where they are harmful, and recovering them as organic inputs for agriculture. We co-create culturally appropriate, circular, and climate-positive systems that promote health, avoid contamination, store CO₂, and restore soil for long-term resilience.
Across Guatemala, unmanaged organic waste is contaminating the soils and water that farmers and communities depend on. Wastewater treatment plants generate approximately 50,000 tonnes of sewage sludge each year, most of which is disposed of unsafely in landfills. Agricultural residues often follow a similar path: left unmanaged, burned, or treated as waste instead of returned to the land.
At the same time, soil depletion, overuse of agrochemicals and intensifying climate stress are increasing crop disease, reducing yields, and weakening farmer resilience in one of the countries most exposed globally to climate-related disasters.
We transform organic residues that would otherwise contaminate the environment into biochar-based soil inputs, enrich them into regenerative substrates, and return them safely to the soil — reducing contamination risk, restoring soil fertility, and helping build more resilient, lower-carbon value chains.
We implement this work through the Mosan Circular System: a mission-driven consortium that brings together nonprofit partners, commercial innovation and strategic partnerships. By bringing together complementary organizations under one shared mission, we connect environmental protection, community engagement, resource recovery and regenerative agriculture into a single integrated system designed for long-term impact.
Sewage sludge, coffee pulp, coconut husks — diverted from landfills, rivers, and lakes.
Waste is converted through high-temperature pyrolysis into safe, high-nutrient biochar and further enriched
Biochar substrates help to restore fertility and resilience; buyers benefit from low-carbon supply.
“All biochar substrates increased moisture retention by over 25%.”“37% decrease in production cost in nursery trials.”“39% increase in coffee plant growth after one year.”

Whether you’re a farmer, a cooperative, a finca owner, a coffee buyer, a research partner, or an impact investor, there’s a way to be part of the loop.
