Impact & Validation

Proven in the field, farmer-centric with science and government partners.

Six years of R&D and field trials with leading universities and Guatemala’s Ministry of Agriculture

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

moisture retention up over 25% in seedling bags; root growth increased by 30%; 37% lower production cost compared to synthetic fertilizer.

Coffee field trial · 2025 · Ministry Collaboration

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

Collaboration with the Coffee Cooperative “La Voz” (partnership since 2023)

first-year 15% yield increase fully offset the cost of biochar (risk-free transition); subsequent years a ~25% yield gain is expected.

ETH Zurich · 9-month Randomized Control Trial

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 PNUD

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

Impact goals
By the end of 2026

treat 300+ tonnes of waste annually, mitigate ~200 tCO₂, reach 200+ farmers.

In 5 years

treat 2,000+ t/year; mitigate 1,000+ tCO₂; support 3,000+ farmers; restore 200+ hectares.
