The Solution

A fully circular system for nutrient recovery, soil regeneration, and resilient agriculture. — not a standalone biochar producer, nor a sole sanitation solution.

The Mosan System builds culturally appropriate, circular, climate-positive solutions through innovative technologies and processes — promoting health, avoiding contamination, storing CO₂, and recovering nutrients for reuse in agriculture, for long-term regeneration and resilience.

The process
Collection & Reception
Stabilization & Treatment
Enrichment & Formulation
Soil Regeneration

We use different treatment processes to transform diverse organic waste streams. At the core is our high-temperature pyrolysis that produces safe nutrient-rich biochar, we further enrich it into a ready-to-apply soil substrate.We pair product development with farmer training and landscape-level regeneration.

Three integrated layers

Waste management

diverting and safely treating waste streams, such as sewage sludge, and agricultural residues that would otherwise contaminate water and soil or cause amounts of greenhouse gas emissions

Soil regeneration

we provide biologically active substrates that restore fertility, retain moisture, and build plant resilience.

Supply-chain integration

our work creates significant climate contributions for buyers. Our current focus allows coffee buyers to reduce emissions inside the supply shed.

The Product

Biochar Substrates

A porous carbon material, developed and tested over six years. Acts as a sponge in the soil and delivers multiple benefits:

  • Increases moisture retention — up to 400%, improving drought resilience
  • Improves soil & plant health — ~10% higher soil pH, less compaction,
  • Habitat for beneficial microorganisms — increases soil biodiversity
  • High in nutrients & minerals — N 2.1%, P₂O₅ 4%, K₂O 2.1%, CaO 6.6%, MgO 1.3%, plus silicate and organic carbon
  • Stores stable carbon — up to 59% carbon (70% stable)

Specialized Biochar Formulations: urine-enriched biochar (for high-nitrogen crops), and worm-compost-enriched for general use (in nurseries, for field application, reforestation, etc.).

Sanitation

The Mosan Toilets

The Mosan story began with a focus on sanitation solutions — pioneering off-grid ecological toilets with the award-winning Mosan Household Toilet and the safe treatment of human excreta. That work became the foundation for everything we do today: the same circular principle, now applied across waste streams and at landscape scale.

The current Mosan Toilet is a fully equipped cabin for public spaces, schools and events. It builds on the design of the former household toilet and brings new innovative features, such as a urine diversion system based on the “tea-pot principle” a waterless men's urinal and wood chip dispenser for “dry flushing” The toilet is part of the circular system and raises awareness about environmental protection and circular innovation through educational elements.
