Pilot-scale production scale-up of biochar for field trials (approx 1–2 t/day)
Hello everyone, it’s a pleasure to be part of this group.
From Argentina, we are researching the technical and economic feasibility of producing biochar from urban pruning residues in large cities where collection is separated and centralized. We have carried out pyrolysis tests and biochar characterization at the laboratory scale, but we now…

Happy 2026, and thank you for being here.
This year marks 20 years of the International Biochar Initiative. Two decades of shared work, debate, learning, and steady progress. What began as a small community has grown into a global network shaping how biochar is produced, applied, and understood.
We are glad to start another year with you. Thank you for your trust, your questions, and…

Biochar Inside the Pile: How Composting Cuts Odors, Emissions, and Nutrient Loss
Composting rarely fails on biology. It fails on neighbors.
Odor complaints, ammonia losses, methane formation, and unstable piles remain the quiet reasons facilities stall, relocate, or shut down. The image circulating from Jaroslav Moudřík and Biochar Chile captures why biochar keeps resurfacing as a serious process tool, not a cosmetic…

Carbon removal vs carbon capture - different jobs
These two keep getting mixed up. They should not.
Carbon removal and carbon capture sound similar. They are not interchangeable. When we blur them, we create confusion for buyers, policymakers, and communities. We also slow down good projects and make bad ones harder to challenge.
Let’s keep it simple.
Carbon removal takes CO₂ already in the air…

Scaling artisanal biochar production
Buyers say they like industrial biochar based carbon removal. Their behavior proves it. Large offtakes. Long contracts. Faster decisions.
So why do artisanal biochar projects struggle to reach the same level of demand?
The common explanations miss the point. This is not about permanence. It is not about climate impact. It is not even about…

Activated vs Unactivated Biochar
Why the Difference Still Gets Missed, and Why Charging Is Not Optional
Biochar use is expanding fast across agriculture, carbon projects, and environmental cleanup. Yet one basic distinction remains blurred. Activated and unactivated biochar are often treated as variations of the same material. They are not. They serve different functions,…

Why does biochar work so well with compost?
Because each fixes real limits of the other.
What the evidence shows?
Scientific literature is consistent. When biochar is added during composting, both processing and agronomic outcomes improve.
An October 2025 peer-reviewed paper shows that, at roughly a 10 percent inclusion rate, co-composting with biochar:
- Reduces nitrogen losses and…
