Impact & Validation

Co-created and tested with farmers, supported by science and institutional partners.

Six years of R&D and field trials with leading universities and in collaboration with government institutions.

Validation highlights
Coffee nursery trial · 2024–2025 · Ministry Collaboration

increased moisture retention by 25% in seedling bags; 30% increase in root growth; 37% reduced production cost compared to seedlings grown with synthetic fertilizer.

Coffee field trial · 2025 · Ministry Collaboration

after one year of growth, biochar-treated plants show a 39% increase in growth compared to plants fertilized synthetically.

Maize · 9-month Randomized Control Trial · 2022–2023 · ETH Zurich Collaboration

urine-enriched biochar raised maize yield by 25% vs. synthetic fertilizer.

Zucchini trial · 2023 · UVG – Guatemalan University Collaboration

urine-enriched biochar outperformed conventional compost (by +44%), chicken manure (by +22%), and vermicompost (by +12%).

Spinach trial · 2024 · Supported by UNDP

enriched biochar doubled the harvest vs. vermicompost alone; biochar treated soil retained 4× more moisture than soil alone.
