Biochar and Soil Amendments in India: Durable Carbon Storage for Sustainable Agriculture

Introduction: Beyond Short-Term Carbon

The world’s carbon removal efforts often focus on trees and soils — vital, but vulnerable. Trees can burn, soil carbon can erode. True climate impact needs durability — carbon that stays locked away for decades or even centuries.

This is where biochar and other soil amendments come in.

Biochar is a stable, carbon-rich material produced by heating organic matter (like crop residues, wood waste, or manure) under low oxygen — a process called pyrolysis. When applied to soils, biochar not only improves fertility and water retention, but also stores carbon for hundreds to thousands of years.

For India — a nation where agriculture and waste management intersect — biochar represents a powerful, scalable, and high-quality carbon removal solution.

The 2025 Criteria for High-Quality Carbon Dioxide Removal highlight durability and environmental co-benefits as essential principles. Biochar checks both boxes.

What Is Biochar?

Biochar is produced when organic biomass — crop residues, husks, twigs, or even municipal green waste — is heated in a low-oxygen environment. Unlike open burning (which releases CO₂), pyrolysis converts much of that carbon into a stable, solid form that resists decomposition.

When applied to soil:

-It enhances soil structure and nutrient retention.

-Increases microbial activity and root growth.

-Holds carbon in a stable state for centuries.

Simply put, it transforms agricultural waste into a permanent carbon sink.

Why Biochar Matters for India

1. Agriculture-Driven Economy

India’s 150+ million smallholder farmers generate vast crop residues. Many burn this biomass, contributing to air pollution and CO₂ emissions. Biochar converts that same waste into soil health and carbon credits.

2. Soil Degradation Crisis

Over 30% of Indian soils are degraded or nutrient-depleted. Biochar improves organic matter, pH balance, and water retention — directly improving productivity.

3. Climate Commitments

Under India’s Nationally Determined Contributions (NDCs) and CCTS (Carbon Credit Trading Scheme), durable carbon removal like biochar will be crucial to long-term decarbonization.

4. Circular Economy Alignment

Biochar ties together agriculture, waste management, and carbon markets — converting local problems into revenue-generating, climate-positive outcomes.

Biochar and Soil Amendments: What’s the Difference?

While “biochar” often gets the spotlight, soil amendments is a broader category.

Type	Description	Carbon Durability	Example Application
Biochar	Pyrolyzed biomass, highly stable carbon	100–1000 years	Crop residue pyrolysis for farm use
Compost	Organic matter decomposition	1–10 years	Manure or green waste for fertility
Enhanced Rock Weathering	Silicate mineral application capturing CO₂	100–10,000 years	Basalt dust on farmlands
Organic Manures / Vermicompost	Natural nutrient recycling	1–5 years	Fertility boost, low permanence

Biochar stands out for durability, but its synergy with other amendments (like compost or rock dust) maximizes soil and carbon benefits — a strategy Anaxee is deploying at scale.

What Makes Biochar “High-Quality” Carbon Removal?

The 2025 Criteria for High-Quality CDR define three pillars for durable removals:

1. Measurement and MRV

Every tonne of carbon must be quantifiable, traceable, and verifiable.

-Biochar MRV involves tracking feedstock type, pyrolysis temperature, and application rate.

-Anaxee’s dMRV system records all these in real time using mobile apps and satellite-linked systems.

2. Durability

Carbon in biochar is chemically stable. Studies show >80% of carbon remains sequestered after 100 years.
This makes biochar one of the most durable CDR pathways available today.

3. Environmental Co-Benefits

High-quality projects enhance soil health, reduce pollution, and improve yields.
Biochar projects align perfectly with climate justice and environmental integrity — avoiding trade-offs like monoculture plantations or fertilizer overuse.

The MRV Challenge (and Opportunity)

Biochar’s credibility depends on robust data — how much carbon is actually stored and for how long.
Traditional MRV struggles with:

-Inconsistent feedstock records

-Lack of local lab analysis

-Fragmented data management

Anaxee’s Digital MRV (dMRV) overcomes this through:

-Geotagged data on biomass source and pyrolysis unit.

-Automated reporting of application areas.

-Satellite imagery cross-verification.

-Blockchain-based data integrity (for future registry integration).

Result: Lower verification costs, faster credit issuance, and traceable impact.

Biochar in Carbon Markets

1. Growing Global Demand

Buyers like Microsoft, Shopify, and Carbonfuture are investing heavily in durable removals, including biochar. Credits fetch $100–$300 per tonne, far above typical forestry credits.

2. Emerging Methodologies

Standards like Puro.Earth, Verra’s Biochar Methodology, and Charm Industrial’s model are shaping a robust global market.

3. India’s Potential

With abundant biomass, low-cost labor, and supportive policy, India could become a biochar export powerhouse — provided quality and verification match global expectations.

Anaxee is positioning its projects to align with these premium markets, offering corporates traceable, durable, and community-positive credits.

The Co-Benefits: Climate, Soil, and People

High-quality biochar projects go beyond carbon:

Impact Area	Description	Example
Climate	Long-term CO₂ sequestration, reduced burning	Avoids stubble burning emissions
Soil Health	Improved fertility, moisture retention, structure	Higher yields for smallholders
Air Quality	Eliminates crop-burning smoke	Cleaner air in rural belts
Livelihoods	Adds rural income via carbon finance	Farmer revenue + local jobs
Circular Economy	Reuses waste, reduces landfill	Biomass → Biochar → Soil health

This is carbon removal that benefits both people and planet.

India’s Biochar Future

India’s next agricultural revolution won’t come from fertilizers — it’ll come from carbon-smart farming.
By 2030, India could:

-Produce 50 million tonnes of biochar annually,

-Sequester over 100 million tonnes of CO₂e, and

-Create millions of rural green jobs.

With the right infrastructure, MRV, and financing, biochar could become India’s signature carbon removal export.

Conclusion: Building Durability into India’s Carbon Story

Carbon markets are evolving fast. The next wave is about durability, traceability, and co-benefits — not just offsets.
Biochar embodies all three.

The 2025 Criteria for High-Quality CDR call for long-lasting, verifiable, socially just solutions.
Anaxee’s biochar model — integrating tech, communities, and dMRV — shows how India can lead this frontier.

As carbon buyers shift from “cheap” to credible, projects like Anaxee’s will define the new gold standard.

Soil Carbon Projects in India: Pathways for High-Quality Carbon Removal with Anaxee

Introduction: The Carbon Beneath Our Feet

When we talk about climate solutions, the focus often goes to trees, solar panels, or electric vehicles. But there’s a silent climate ally right beneath us: soil.

Globally, soils store more carbon than the atmosphere and vegetation combined. Healthy soils are not just the backbone of agriculture; they are also a massive carbon sink. By adopting the right practices, farmers can draw down atmospheric carbon into soils—locking it away while boosting fertility, water retention, and resilience.

The 2025 Criteria for High-Quality CDR recognizes soil carbon as a key pathway, but with important caveats: measurement, durability, and community justice are critical.

For India—a country with over 150 million smallholder farmers—soil carbon is not just about climate. It’s about livelihoods, food security, and creating a new income stream through carbon finance.

What Is Soil Carbon Removal?

Soil carbon removal involves changing land management practices so that more carbon is stored in soils. This can be achieved through:

-Regenerative agriculture – practices like cover cropping, crop rotation, reduced tillage.

-Agroforestry – integrating trees into farmland.

-Organic soil amendments – compost, biochar, or enhanced rock weathering.

-Pasture management – rotational grazing that enhances soil cover.

These changes help soils absorb and retain more organic carbon, turning farms into climate-positive landscapes.

Why Soil Carbon Matters for India

1. Agriculture Is Both Vulnerable and Powerful

Agriculture contributes to India’s emissions (methane, nitrous oxide), but it is also extremely vulnerable to climate change. Soil carbon projects can reverse degradation, improve yields, and build resilience.

2. Rural Livelihoods

Most Indian farmers operate on marginal lands with tight incomes. Soil carbon credits offer new revenue streams through global carbon markets—helping farmers while fighting climate change.

3. Scale

With millions of hectares of farmland, even modest improvements in soil carbon storage can translate into gigatonne-scale removals.

What Makes a High-Quality Soil Carbon Project?

According to the 2025 Criteria, soil carbon projects must meet strict benchmarks:

1. Social and Environmental Justice

-Ensure farmers are not locked into harmful contracts.

-Guarantee fair benefit-sharing from carbon revenues.

-Protect communities from risks like rising input costs.

2. Environmental Integrity

-Avoid overuse of fertilizers or chemicals that harm ecosystems.

-Promote biodiversity, soil health, and water retention.

3. Additionality and Baselines

-Show that soil practices would not have been adopted without carbon finance.

-Set conservative baselines that account for natural regeneration.

4. MRV (Measurement, Reporting, Verification)

-Use peer-reviewed models and direct sampling.

-Monitor soil carbon changes with scientific rigor.

-Combine field sampling with remote sensing for accuracy.

5. Durability

-Soil carbon is reversible—droughts, floods, or practice abandonment can release carbon. Projects must plan for long-term adoption and risk mitigation.

6. Leakage

-Prevent displacement of practices—e.g., if reduced tillage here leads to over-tillage elsewhere.

The Challenges in Soil Carbon

Soil carbon is powerful but tricky:

-Measurement Uncertainty – detecting small year-to-year changes is scientifically challenging.

-Permanence Risks – carbon can be re-released if practices stop.

-Farmer Adoption – smallholders may hesitate without upfront support.

-Market Trust – buyers worry about inflated or unverifiable credits.

This is why soil carbon must be implemented with robust MRV, long-term planning, and community-first approaches.

Anaxee’s Approach to Soil Carbon in India

Anaxee is working to make soil carbon projects credible, scalable, and farmer-friendly. Here’s how:

1. Farmer-Centric Model

-Blended portfolios: combining soil projects with agroforestry for durability.

-Early warning systems for risks like droughts.

4. Scale and Reach

-With 40,000+ Digital Runners across 26 states, we can engage farmers at scale.

-From Bund plantations in central India to regenerative farming in Punjab, Anaxee ensures projects are grounded in local context.

Soil Carbon and Global Carbon Markets

Buyers like Microsoft, Stripe, and Frontier are seeking high-quality removals—not just offsets. Soil carbon, if implemented well, can meet this demand.

However, buyers demand:

-Transparency in MRV.

-Durability guarantees.

-Clear community benefits.

By embedding the 2025 Criteria, Anaxee ensures Indian soil carbon projects meet global expectations while delivering local impact.

Case Example: Bund Plantations with Soil Benefits

In Madhya Pradesh, Anaxee has been implementing bund plantations (tree planting along farm bunds). These projects not only sequester carbon in trees but also:

-Reduce soil erosion.

-Improve water retention.

-Enhance soil organic matter.

Farmers see higher yields, lower risks, and additional carbon revenue—a model that aligns with soil carbon criteria while benefiting communities.

India’s Role in Scaling Soil Carbon

Globally, soil carbon is seen as one of the most scalable and affordable CDR solutions. For India:

-The sheer scale of agriculture makes it a climate opportunity.

-Programs like National Mission for Sustainable Agriculture can align with soil carbon.

-Carbon finance can create new rural economies.

The challenge is ensuring projects are high-quality, transparent, and durable. That’s the gap Anaxee fills.

Conclusion: Soil Carbon as India’s Climate and Rural Opportunity

Soil carbon is more than a climate tool—it’s a bridge between global carbon markets and local livelihoods. Done right, it improves soils, strengthens food systems, and rewards farmers while delivering credible removals.

But the “done right” is key. Without robust MRV, durability, and justice, soil carbon risks becoming another failed promise. With frameworks like the 2025 Criteria for High-Quality CDR, we now have the roadmap.

Anaxee is bringing that roadmap to life in India—combining tech, trust, and last-mile execution to ensure soil carbon projects are globally credible and locally transformative.

The future of climate action lies beneath our feet. It’s time we nurture it.

High-Quality Carbon Dioxide Removal: Why It Matters and How Anaxee is Delivering It in India

Introduction: Why Carbon Removal Matters Now

The climate clock is ticking. The IPCC’s AR6 report is clear: reducing emissions alone will not keep us under the 1.5°C threshold. Alongside decarbonization, the world must actively remove between 100–1000 billion tonnes of CO₂ by 2100. That means by 2050, we need 5–10 billion tonnes of carbon removed annually.

But not all carbon removal is created equal. Many projects claim removals, yet face problems—weak baselines, double counting, lack of monitoring, or poor durability. This is why the 2025 Criteria for High-Quality Carbon Dioxide Removal was published—to set clear principles that ensure credibility, durability, and justice in the CDR industry.

For India, where millions depend on land, forests, and agriculture, ensuring quality in carbon projects is not just about climate—it is about livelihoods, ecosystems, and trust. And that’s where Anaxee steps in.

2. What Makes CDR “High-Quality”?

The 2025 criteria highlight seven essential pillars that define quality in carbon removal projects:

Social and Environmental Justice – projects must avoid harms and deliver fair benefits to local communities.
Environmental Integrity – protecting biodiversity, soil health, and water.
Additionality and Baselines – removals must be real and beyond business-as-usual.
Measurement, Monitoring, Reporting, Verification (MRV) – science-based, transparent, and third-party verified.
Durability – ensuring captured carbon stays out of the atmosphere for decades or centuries.
Leakage Control – avoiding displacement of emissions elsewhere.
Effective Project Management – governance, transparency, and accountability.

Without these principles, carbon projects risk becoming “paper credits”—numbers that look good for corporate reporting but fail to deliver real climate impact.

3. Nature-Based vs. Engineered CDR

The report covers both nature-based (forestation, mangroves, soil carbon, agroforestry, rock weathering) and engineered methods (direct air capture, mineralization, biomass with storage).

-Nature-based solutions (NbS): cost-effective, co-benefits like biodiversity and livelihoods, but challenges in durability and MRV.

-Engineered solutions: durable storage, but expensive and limited in scale today.

In India, the immediate opportunity lies in NbS—where rural landowners, farmers, and communities can participate, provided projects follow high-quality criteria.

4. The Risk of Low-Quality Carbon Projects

A growing criticism of carbon markets is the prevalence of low-quality credits:

-Plantations in wrong ecosystems (biodiversity loss).

-Short-term projects that collapse after a few years.

-Lack of consent or benefit-sharing with communities.

-Inflated baselines that exaggerate impact.

Such failures create reputational risk for buyers and resentment among communities. Worse, they delay real climate action. That’s why frameworks like the 2025 Criteria matter—they separate meaningful carbon removals from greenwashing.

5. How Anaxee Adds Value in High-Quality CDR

Anaxee is positioning itself as India’s Climate Execution Engine, ensuring projects meet the highest global benchmarks. Here’s how:

-Last-Mile Reach: With 40,000+ Digital Runners across 26 states, Anaxee mobilizes rural communities at scale for afforestation, soil carbon, and agroforestry projects.

-dMRV Tools: In-house apps, geotagging, and AI-driven verification ensure transparent and traceable monitoring of every tree, farm, and intervention.

-Community-Centered Models: Farmers and landowners are direct beneficiaries—through revenue share, training, and alternative livelihoods.

-Transparency & Compliance: Projects align with Verra (VM0047, ARR, Soil Carbon), Gold Standard, and now emerging high-quality CDR criteria.

-Durability Assurance: Long-term contracts, diversified project portfolios, and adaptive management mitigate reversal risks.

In short, Anaxee bridges the gap between global buyers demanding quality and local communities implementing projects on the ground.

6. India’s Role in the Global CDR Market

Globally, companies like Microsoft are already purchasing millions of tonnes of removals, For India, this creates an economic opportunity:

-Farmers and rural communities can access carbon finance.

-Corporates can meet CCTS (Carbon Credit Trading Scheme) compliance and voluntary commitments.

-India can position itself as a hub for NbS carbon credits, provided the projects are high-quality.

Anaxee’s role is to ensure India’s carbon projects are not just cheap offsets, but globally credible removals that meet durability, MRV, and justice standards.

7. The Road Ahead: Scaling Quality, Not Just Quantity

Scaling CDR is not just about planting millions of trees—it’s about doing it right. The future of the carbon market depends on trust. That means:

-Buyers must demand high-quality removals only.

-Developers must invest in dMRV and transparent reporting.

-Communities must be equal partners in the climate economy.

Anaxee’s Climate Command Centre, community-first models, and tech-driven transparency offer a template for how India can scale CDR without repeating past mistakes.

8. Conclusion

High-quality carbon removal is no longer optional—it is the foundation of credible climate action. The 2025 criteria give the world a common yardstick. For India, the challenge is turning these principles into practice at scale.

Anaxee is already doing this—by combining tech, trust, and last-mile reach to deliver projects that remove carbon, support communities, and stand up to global scrutiny.

Types of Carbon Projects: Archetypes, Cashflows, and Financing Models

Types of Carbon Projects and Their Investment Archetypes

Introduction

Carbon projects are not one-size-fits-all. They vary in design, cost, timelines, and financing needs depending on whether they remove carbon from the atmosphere or prevent emissions in the first place. For investors and developers, understanding these differences is essential. The Carbon Finance Playbook highlights how each project archetype carries a unique cashflow model, risk profile, and capital requirement. In this blog, we’ll break down the most common types of carbon projects in emerging markets, explain their archetypes, and explore how financing strategies are tailored to each one.

Carbon Project Categories: Removal vs Avoidance

Infographic comparing carbon project categories — removal projects that extract existing carbon through methods like tree planting and direct air capture, and avoidance projects that reduce future emissions through forest protection and renewable energy.

At a high level, projects fall into two buckets:

Carbon Removal Projects: These actively take carbon out of the atmosphere and store it long-term. Examples include reforestation, biochar, and blue carbon projects. They often require heavy upfront investment but deliver robust long-term carbon benefits.
Carbon Avoidance Projects: These prevent emissions that would otherwise occur. Examples include REDD+ forest protection, improved cookstoves, and solar irrigation pumps. They tend to have lower upfront costs but rely on monitoring to prove avoided emissions.

Both categories are crucial for meeting global climate goals, and each has different implications for capital raising.

Common Types of Carbon Projects

1. REDD+ (Reducing Emissions from Deforestation and Degradation)

-What it is: Protects existing forests by working with local communities or governments to prevent logging and land-use change. -Why it matters: Tropical forests are massive carbon sinks. Preventing deforestation avoids huge emissions. -Financing needs: Relatively low upfront costs (10–20% of total) but long-term operating expenses (community payments, patrols, monitoring). -Revenue model: Steady issuance of credits over 20 years; break-even in 3–7 years.

2. ARR (Afforestation, Reforestation, Revegetation)

-What it is: Planting trees or restoring degraded land. -Why it matters: Removes carbon and supports biodiversity. -Financing needs: High upfront investment (50–80% in first 5 years) for nurseries, labor, and land. -Revenue model: Credits ramp up in years 5–15 as trees grow. Break-even usually 8–15 years.

3. Blue Carbon

-What it is: Protecting or restoring coastal ecosystems such as mangroves and tidal marshes. -Why it matters: These ecosystems store carbon at much higher densities than terrestrial forests. -Financing needs: Similar to ARR, with significant costs for restoration and long-term monitoring. -Revenue model: Generates premium-priced credits due to high co-benefits like storm protection and fisheries support.

4. Cookstoves

-What it is: Distributing efficient cookstoves that reduce firewood or charcoal use. -Why it matters: Avoids emissions, improves health, and reduces deforestation. -Financing needs: Moderate upfront costs for production and distribution. -Revenue model: Credits issued immediately after adoption; steady flow tied to usage.

5. Solar Irrigation

An Anaxee field worker photographs a ground-mounted solar panel array in a lush farm, documenting a solar-agriculture pilot in rural India.

-What it is: Replacing diesel pumps with solar-powered systems. -Why it matters: Cuts emissions and boosts resilience for smallholder farmers. -Financing needs: High per-unit cost, but scalable with carbon subsidies. -Revenue model: Carbon credits lower the retail price, expanding adoption.

6. Biochar and Enhanced Rock Weathering

-What it is: Capturing carbon in biomass (biochar) or minerals (rock weathering). -Why it matters: Offers long-term or permanent storage. -Financing needs: Capital-intensive with significant R&D and infrastructure costs. -Revenue model: Premium credits, but smaller market compared to REDD+ and ARR.

Archetypes of Carbon Projects

The Playbook identifies three major investment archetypes:

Archetype 1: Capital-Light Projects (Avoided Emissions)

-Examples: REDD+, improved cookstoves. –Cashflows: Relatively quick credit issuance (1–2 years), steady revenues. – Investment profile: Low upfront capital, shorter payback (3–7 years).

Archetype 2: Capital-Intensive Projects (Carbon Removal)

-Examples: Reforestation, blue carbon restoration. -Cashflows: Credits ramp up after 4–7 years as biomass grows. -Investment profile: High upfront costs, long payback (8–15 years).

Archetype 3: Product-Linked Projects (Carbon Subsidies)

-Examples: Cookstoves, solar irrigation. –Cashflows: Revenue from both product sales and carbon credits. –Investment profile: Flexible funding models; credits reduce upfront price for customers, widening adoption.

Cashflow Profiles and Break-Even Timelines

–Avoided Emissions Projects: Consistent year-to-year credit generation; revenue depends on baseline deforestation or energy use avoided. –Restoration Projects: “S-curve” credit generation, peaking in mid-years of project life. –Product Subsidy Projects: Mixed streams from sales and credits; scalability depends on demand elasticity.

Financing Models for Carbon Projects

Pre-Sale of Credits: Developers sell credits at a discount to raise upfront capital.
Strategic Investors: Corporates that need credits invest in projects directly.
Blended Finance: Mixing grants and concessional capital with private money to reduce risk.
Insurance Products: Guarantee credit delivery and reduce investor concerns.

Why Archetypes Matter for Investors

Each archetype dictates: -Time to cashflow positivity. -Risk exposure (political, environmental, price volatility). -Financing structure (equity, debt, grants). For instance: -REDD+ projects are attractive for early credit generation but face political and reputational risks. -Reforestation projects deliver higher integrity and premium credits but require patience. -Cookstove projects scale fast but need careful monitoring of usage.

Conclusion

Carbon projects come in many shapes and sizes, from protecting forests to distributing clean energy products. Understanding whether a project is capital-light, capital-intensive, or product-linked is essential for both developers and investors. The right financing model can accelerate implementation, reduce risks, and ensure both climate and community benefits. In short: no two carbon projects are the same. Investors and developers who understand these archetypes can build smarter partnerships and unlock the true potential of carbon finance in emerging markets.

The Biochar Value Chain: From Waste Biomass to Climate Solutions

The Biochar Value Chain: From Waste to Climate Solution

Introduction

When people talk about carbon removal, the conversation often focuses on futuristic machines or billion-dollar projects. But one of the most effective tools is already around us: biochar.

What makes biochar special is not only its ability to store carbon for centuries but also the way it connects farmers, industries, and local communities in a chain that turns waste into value. This “biochar value chain” starts with biomass residues and ends with climate benefits, soil improvement, and new income streams.

In this blog, we’ll unpack the biochar value chain step by step — from feedstock to pyrolysis to applications — and show why it is becoming one of the most scalable climate solutions of our time.

1. Understanding the Biochar Value Chain

At its core, the biochar value chain links together:

Feedstock sourcing – agricultural residues, forestry waste, animal manure, food processing leftovers.
Conversion process – mainly pyrolysis, which transforms biomass into biochar plus co-products.
Applications – biochar used in soils, construction, water purification, animal feed, and more.
Carbon finance – projects earn carbon credits for the carbon they lock away.

This chain is flexible. In some places, it is small-scale, community-driven with simple kilns. In others, it is highly industrial, producing thousands of tons annually.

2. Feedstock: Turning Waste into Opportunity

Person feeding agricultural residues into a pyrolysis unit for biochar production in an outdoor field setup.

Biochar projects begin with feedstock — the raw biomass. Not all feedstock is equal, and sustainability is crucial.

🌾 Types of Feedstock

-Agricultural residues: rice husks, maize stalks, sugarcane bagasse.

-Forestry residues: wood chips, sawdust, pruning waste.

-Animal waste: manure, poultry litter.

-Food processing residues: shells, husks, fruit pits.

-Other waste streams: sewage sludge, organic municipal waste.

♻️ Why Feedstock Matters

-If biochar is made from waste biomass, it creates a double benefit: preventing methane emissions from open decomposition while locking carbon.

-If made from purpose-grown crops, it risks competing with food production or land use. That’s why most high-quality projects stick to true waste materials.

🌍 Sustainability Concerns

Feedstock must be traceable, free from contaminants, and not diverted from other uses (like animal fodder or energy). Good projects document every stage of sourcing.

3. Pyrolysis: The Heart of Biochar Production

Once feedstock is collected, it undergoes pyrolysis. This is where the real transformation happens.

🔥 What is Pyrolysis?

A thermochemical process that heats biomass at 500–700°C in a low-oxygen environment. The result is:

-Biochar (solid carbon)

-Bio-oil (liquid fuel)

-Syngas/biogas (usable gas energy)

-Heat and electricity (in advanced systems)

🛠️ Types of Pyrolysis Technologies

-Low-tech / artisanal kilns (like Kon-Tiki kilns, soil pits, micro-gasifier stoves).

- ✅ Advantages: Cheap, accessible, creates rural jobs.
- ❌ Challenges: Lower efficiency, harder to measure methane emissions.

-High-tech / industrial pyrolysis (fixed-bed, rotary kilns, auger reactors).

- ✅ Advantages: High efficiency, precise monitoring, by-product utilization.
- ❌ Challenges: Requires big investment and stable feedstock supply.

⚖️ Striking a Balance

Some mid-tech systems blend artisanal and industrial methods, offering flexibility without huge infrastructure costs. This makes pyrolysis adaptable across geographies.

4. The Variety of Biochar Applications

The end use of biochar is where the value chain becomes diverse and exciting. Unlike other carbon removal technologies that only store carbon, biochar has multiple functional uses.

🌱 Agriculture

-Improves soil fertility, crop yields, and water retention.

-Reduces fertilizer demand.

💧 Water & Waste

-Filters heavy metals and pollutants.

-Used in wastewater treatment.

-Helps with mine remediation and erosion control.

🏗️ Construction & Industry

-Strengthens concrete and asphalt.

-Provides insulation and reduces cement demand.

🐄 Livestock & Food Chain

-Added to animal feed to improve digestion and reduce methane emissions.

-Used in food packaging as a safe additive.

🌍 Circular Economy

Every application adds new revenue streams. For example, selling biochar for soil amendments creates local markets, while industrial applications attract global buyers.

5. By-Products: Beyond Biochar

Biochar production doesn’t stop at the solid product. Depending on the technology, valuable co-products emerge:

-Syngas and heat for electricity or cooking.

-Bio-oil as a renewable fuel.

-Wood vinegar and other chemicals for agriculture.

In some cases, these co-products can make the entire operation self-sustaining — even powering the pyrolysis plant itself.

6. Adding Carbon Finance to the Chain

The big game-changer for the biochar value chain is the voluntary carbon market. By proving that carbon is locked away permanently, projects can issue carbon credits.

📜 Registries and Methodologies

-Verra (VM0044 Biochar Utilization)

-Puro.earth (Biochar Standard)

-Isometric

-CSI Artisan & Global Biochar C-Sink

These methodologies set strict rules: feedstock eligibility, production monitoring, end-use verification. Buyers pay for the carbon removal value of biochar, often at higher prices than typical avoidance credits.

7. Socio-Economic Impact of the Biochar Chain

For many regions in the Global South, biochar is not just about climate — it is about livelihoods.

-Creates rural jobs in biomass collection and pyrolysis.

-Provides farmers with affordable soil amendments.

-Brings women and marginalized groups into production networks.

-Supports community resilience against climate shocks.

Case studies (like Carboneers in India, Ghana, and Nepal) show how biochar projects can increase household incomes by 500% or more while delivering verified climate impact.

8. Challenges in the Value Chain

Like any system, the biochar chain faces hurdles:

-Supply chain risks – securing consistent feedstock.

-Monitoring issues – especially in decentralized artisanal projects.

-Market mismatch – suppliers need $180/ton, buyers want $130/ton.

-Awareness gap – many industries and policymakers still underestimate biochar’s potential.

Solutions include stronger digital MRV tools, cooperative models for smallholders, and long-term offtake contracts that give producers stability.

9. Why the Biochar Value Chain Matters

Unlike other CDR methods that rely solely on technology, the biochar value chain:

-Links waste to value.

-Combines climate action with economic development.

-Offers co-benefits across food, water, and energy.

-Is scalable now, not decades from now.

This makes it one of the most practical pathways to combine carbon removal with sustainable development goals (SDGs).

Conclusion

The biochar value chain is more than a process. It is a system of connections — from farmers managing crop residues, to engineers running pyrolysis reactors, to buyers of carbon credits, and communities benefiting from healthier soils and new incomes.

At every stage, biochar delivers multiple wins: locking carbon, improving ecosystems, generating jobs, and creating renewable by-products.

As the world looks for scalable, durable carbon removal strategies, the biochar value chain shows that solutions can be both high-impact and accessible.

In short: biochar doesn’t just remove carbon. It transforms waste into opportunity and connects climate goals with human well-being.

Rock Weathering: A Natural Climate Solution Transforming Carbon Removal

Introduction: Why We Need to Look Beneath Our Feet

As climate change accelerates, the urgency to remove carbon dioxide (CO₂) from the atmosphere has intensified. Governments, companies, and climate scientists are searching for scalable, affordable, and permanent solutions. Among nature-based and tech-assisted methods, one solution that’s gaining traction yet remains under-discussed is “rock weathering.” This naturally occurring geological process may not sound revolutionary, but its potential to sequester billions of tonnes of carbon is drawing serious attention.

India, too, with its vast basaltic formations and mineral-rich terrain, is uniquely positioned to lead in the application of this method — especially with the emergence of Article 6 mechanisms and India’s own Carbon Credit Trading Scheme (CCTS). But before we get to the market opportunities, let’s understand what rock weathering actually is.

1. What is Rock Weathering?

Rock weathering is the natural process by which rocks break down over time due to exposure to air, water, and biological activity. When it comes to climate, we are specifically interested in a sub-type called “chemical weathering” — particularly of silicate minerals.

Here’s how it works:

-Silicate rocks (like basalt or olivine) react with atmospheric CO₂ and rainwater.

-This forms bicarbonates, which are eventually washed into the oceans.

-Over thousands of years, the bicarbonates turn into carbonates and are stored in marine sediments — effectively locking away CO₂.

This process has been regulating Earth’s climate for millions of years, but it operates on geological timeframes. What’s new is the idea of “enhanced weathering.”

2. Enhanced Weathering: Speeding Up a Natural Process

Enhanced weathering is a climate intervention technique that aims to accelerate this natural CO₂ removal process by:

-Crushing silicate rocks to increase surface area

-Spreading them over farmland, grasslands, or degraded land

-Letting rainfall and soil processes do the rest

One of the key advantages is that this method is permanent, meaning the captured carbon doesn’t get released back into the atmosphere like in many short-term offset projects. And it does not require massive infrastructure.

Think of it as turning crushed rock into a carbon sponge.

3. The Science Behind It

The chemical formula for the reaction is often simplified like this:

This means one molecule of silicate binds with one molecule of CO₂ to form solid calcium carbonate and silica.

Some popular rocks for this purpose include:

-Olivine – Found in dunite, highly reactive with CO₂

-Basalt – Abundant in India’s Deccan Plateau

-Peridotite – Found in ophiolites, very high in magnesium silicates

The key is the reaction kinetics — how fast the rocks weather in a given climate and soil condition. Humid tropical environments like India offer excellent conditions for faster weathering.

4. Agronomic Co-benefits: More Than Just Carbon

Interestingly, this approach doesn’t just sequester carbon. It also improves soil health:

-Reduces soil acidity – A natural liming effect, particularly helpful in acidic soils

-Adds nutrients – Basalt contains potassium, calcium, and magnesium

-Improves water retention – Microporous crushed rock increases soil capacity

-Boosts crop yields – Some early studies show 5–10% increase in output

This makes it ideal for integrating with agricultural programs, especially in smallholder farming systems like India’s. Enhanced rock weathering could serve dual purposes: climate mitigation and rural soil rejuvenation.

5. Potential in India: A Hidden Advantage

India’s geology offers one of the largest contiguous basalt formations in the world — the Deccan Traps, spanning Maharashtra, Madhya Pradesh, Gujarat, and parts of Telangana and Karnataka. These rocks are not just abundant but also underutilized.

Why India is Strategically Positioned:

Factor	India’s Advantage
Rock Availability	Extensive basalt from Deccan Trap
Climate Suitability	Monsoonal rains, warm temperatures
Agricultural Integration	Smallholder farms, acidic soils in many regions
Labor Force	Rural outreach potential for spreading material
Policy Environment	CCTS and Voluntary Carbon Market reforms

If India scales this approach regionally, it could create a climate-positive agri-revolution.

6. Rock Weathering vs. Other Carbon Removal Methods

Let’s compare rock weathering with some other popular carbon removal approaches:

Approach	Cost (USD/tCO₂)	Permanence	Co-benefits	Maturity
Rock Weathering	$50–$150	1,000+ yrs	Soil, yield	Emerging
Biochar	$30–$120	100–500 yrs	Soil fertility	Mature
DAC (Direct Air Capture)	$600–$1000+	1,000+ yrs	None	Nascent
Afforestation	$10–$50	Decades	Biodiversity	Mature
Soil Carbon	$15–$50	Short-term	Agronomic benefits	Mature

What stands out is the permanence of rock weathering — it offers high-integrity carbon removal without the risk of reversal.

7. Current Research and Pilot Projects

Globally, organizations like UNDO (UK), Project Vesta (US), and Lithos Carbon (US) are conducting large-scale field trials. Some early learnings include:

-Fine particle size increases weathering speed

-Optimal pH and microbial activity boost CO₂ capture

-Yield gains create additional incentives for farmers

In India, few pilots are underway — mostly in Karnataka and Maharashtra, often piggybacking on regenerative agriculture or CSR programs. The current bottleneck? Lack of awareness, field-level deployment partners, and MRV (Monitoring, Reporting, Verification) frameworks.

This is where outreach-focused organizations like Anaxee can play a crucial role.

8. MRV for Rock Weathering: The Tech Challenge

Measuring how much CO₂ has been captured through rock weathering isn’t straightforward. It requires:

-Soil and water sampling – Bicarbonate concentrations, pH shifts

-Isotope tracing – Carbon isotopes to confirm geological origin

-Modeling weathering rates – Using geochemical software like PHREEQC

-Remote sensing and AI – For monitoring deployment and crop impact

Emerging dMRV platforms can help digitize this — using drone surveys, soil sensors, and machine learning to predict and verify CO₂ sequestration.

9. Policy and Carbon Market Integration

Enhanced rock weathering is already recognized by:

-IPCC as a negative emissions technology

-Puro.earth as a certifiable carbon removal methodology

-Verra is in the process of developing weathering protocols

-CCTS (India) can enable voluntary issuance in a co-benefit-linked framework

As India’s carbon market matures under Article 6.2 and 6.4, early projects in rock weathering can be positioned for future trading. Particularly if India adopts a separate track for durable carbon removals — as seen in the EU and US.

10. Risks and Criticism: A Balanced View

No solution is perfect. Rock weathering faces challenges:

-Dust inhalation – Crushed rocks need safe handling protocols

-Energy use – Crushing rocks consumes energy; needs renewable power

-Ecological impact – Mining new rock could harm ecosystems

-Measurement uncertainty – Requires sophisticated MRV, still evolving

Mitigation involves using mine tailings, renewable-powered crushing, and targeting degraded land for spreading.

11. What’s Next: The Road to Scale

Here’s how this can move from pilot to large-scale deployment in India:

Mapping basalt deposits – Government geological surveys + remote sensing
Farmer partnerships – Particularly in acidic-soil districts
Integration with CSR/NbS – Projects by corporates looking for removals
MRV stack development – With tech partners and carbon platforms
Carbon credit registration – Either with Verra, Gold Standard, or future Indian registries

Anaxee, with its rural last-mile capabilities and tech-enabled tracking, is well placed to be an execution partner in this new frontier.

Conclusion: Turning Rocks into a Climate Asset

Rock weathering represents the fusion of deep-time geology with cutting-edge climate science. It’s quiet, solid, and permanent- just like the rocks themselves. And it could turn India’s volcanic past into a climate-secure future.

As the carbon market shifts toward durable removals, enhanced rock weathering offers India a rare opportunity: to lead the world by deploying a homegrown, natural climate solution — quite literally — from the ground up.
