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 stable carbon, and restore soil health for long-term resilience.
Across Guatemala, unmanaged organic waste is contaminating the soils and water that farmers and communities depend on. Wastewater treatment plants in Guatemala collectively generate an estimated 50,000 tonnes of sewage sludge each year, much of which is disposed of in landfills without adequate controls. At the same time, only about 16.5% of Guatemala’s population uses safely managed sanitation services, leaving most human waste without reliable containment or treatment. Agricultural residues often follow a similar path: left unmanaged, burned, or treated as waste instead of returned to the land.
Meanwhile, 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, excreta, coconut residues and other organic residues are diverted from landfills, rivers, and lakes.
Waste is converted through high-temperature pyrolysis into stable biochar then enriched into soil substrates.
Biochar substrates help restore fertility, improve resilience and keep carbon in the soil — supporting healthier farms and lower-carbon value chains.
“39% increase in coffee plant growth after one year.”

By 2030, we aim to treat 2,370 tonnes of organic waste annually and produce 1,170 tonnes of biochar-based substrate — avoiding an estimated 2,270 tonnes of CO₂e in greenhouse gas emissions while storing 234 tonnes of CO₂e as stable carbon in soils.
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.
