The Two Value Chains of Biochar: Physical Products vs Carbon Credits
The biochar sector is unique because it operates across two distinct but interconnected value chains: the physical biochar market and the carbon credit market. Understanding the differences, synergies, and tensions between these two chains is essential for anyone looking to succeed in the biochar industry, according to the Nitidae Biochar Market Study (June 2025).
1. The Physical Biochar Value Chain
This chain focuses on the production and sale of biochar as a tangible product. Biochar is applied in various “matrices” such as soil, fertilizers, animal feed, construction materials, or filtration systems.
Key Applications Include:
- Soil amendment and enhanced fertilizers (the largest potential market)
- Horticulture and growing substrates
- Animal feed additives
- Construction materials (concrete, asphalt)
- Water and air filtration
Current Status: Physical biochar demand remains relatively limited. Prices typically range from $70 to $300 per ton depending on quality and region. Many projects, especially in Europe, donate or sell biochar at low prices because their main revenue comes from carbon credits.
Challenges:
- Low farmer awareness and lack of long-term field data
- Need for significant marketing, R&D, and technical support
- Competition with established products (compost, chemical fertilizers, peat)
- Logistics costs and limited distribution networks
2. The Carbon Credit Value Chain (Biochar Carbon Removal – BCR)
This is currently the dominant economic driver for most biochar projects. Biochar is recognized as a high-quality, durable Carbon Dioxide Removal (CDR) solution.
Key Features:
- One ton of biochar typically generates 2 to 3 tons of CO₂e credits
- Prices currently range between $100 – $300+ per credit
- Major buyers include Microsoft, Google, and other large corporations
- Standards: Puro.earth, Carbon Standard International (CSI), Verra, Isometric
Advantages:
- High and relatively stable revenue compared to physical sales
- Enables faster project scaling
- Attracts significant investment
3. Interaction Between the Two Chains
The Nitidae report stresses that the most successful projects integrate both value chains:
- Circular Models (NetZero, HUSK): Collect biomass waste → produce biochar → distribute it back to the same farmers who supplied the biomass. This minimizes logistics emissions (important for Life Cycle Assessment) and creates strong local buy-in.
- Revenue Structure: Many projects earn 20–80% of income from carbon credits, with the rest from physical biochar or by-products (syngas, bio-oil).
- Additionality Challenge: Carbon standards require projects to prove they need credit revenue to be viable. Heavy reliance on physical sales can sometimes complicate certification.
Strategic Implications for Project Developers
- Industrial Projects: Often prioritize carbon credits initially while gradually building physical markets.
- Artisan Projects: Focus more on local physical use and community benefits, with carbon credits as supplementary income.
- Optimal Strategy: Develop both markets simultaneously. Strong physical demand reduces risk from carbon price volatility.
Opportunities in the Mekong Region
The Mekong Basin is exceptionally well-suited for integrated models thanks to abundant agricultural residues (rice husks, coffee parchment, cashew shells) and high demand for soil improvement. Mekong Biochar Initiative (MBI) specializes in developing projects that balance both value chains — generating carbon revenue while delivering real agronomic benefits to smallholder farmers.
Conclusion
The dual value chain structure is both a challenge and a major strength of the biochar sector. Projects that master both physical application and carbon credit generation will have the highest chance of long-term success and resilience. As the industry matures, the ability to create genuine local demand for physical biochar will become increasingly important alongside carbon finance.
Mekong Biochar Initiative is actively supporting the development of balanced, circular biochar projects across the Mekong region that deliver measurable impact on climate, soil health, and farmer livelihoods.
