Biochar Project Development: From Biomass to Verified Carbon Removal

Biochar is gaining recognition as one of the most practical pathways for durable carbon removal. It can transform agricultural residues, forestry byproducts, and other eligible biomass into a stable, carbon-rich material with commercial and environmental value.

However, producing biochar does not automatically create a credible carbon credit project.

A biochar project becomes a credible carbon asset when it can demonstrate that its feedstock, technology, carbon accounting, monitoring systems, environmental safeguards, and commercial model can withstand independent review.

This is where carbon project development becomes essential.

A properly developed project establishes how carbon removal will be quantified, monitored, validated, verified, registered, and ultimately converted into high-integrity carbon credits. It also helps project owners determine whether the opportunity is technically viable and financially credible before significant capital is committed.

What Is Biochar?

Biochar is a porous, carbon-rich material created by heating biomass in an oxygen-limited environment through a process called pyrolysis.

Potential feedstocks may include:

• Agricultural residues

• Forestry residues

• Wood-processing byproducts

• Crop residues

• Certain organic waste streams

• Purpose-grown biomass, where permitted by the applicable methodology

During normal decomposition or combustion, much of the carbon contained in biomass is returned to the atmosphere. Pyrolysis converts a portion of this biomass carbon into a more stable form that decomposes much more slowly.

When the resulting biochar is placed into an eligible long-term application, part of the carbon originally absorbed from the atmosphere can remain stored for decades or centuries.

The exact durability assigned to a project depends on the biochar’s characteristics, production conditions, testing methods, storage pathway, and the requirements of the selected carbon standard.

How Biochar Removes Carbon from the Atmosphere

Plants remove carbon dioxide from the atmosphere through photosynthesis and store that carbon within their tissues.

Without intervention, most of this carbon eventually returns to the atmosphere through decomposition, fire, or combustion. A biochar project interrupts part of this cycle.

The general carbon removal pathway is:

1. Plants absorb carbon dioxide from the atmosphere.

2. Biomass containing that carbon is collected.

3. The biomass is converted into biochar through controlled pyrolysis.

4. The biochar is tested to determine its carbon content and stability.

5. The biochar is placed into an eligible long-term application.

6. Project emissions are calculated and deducted.

7. The remaining net carbon removal is independently verified.

The project must account for more than the amount of biochar produced.

Carbon accounting may include feedstock collection, preprocessing, transportation, electricity consumption, fuel use, production emissions, methane emissions, biochar yield, carbon stability, product transportation, and final use.

The result is a calculation of net carbon dioxide removal rather than gross biochar production.

Biochar Production Is Not the Same as Carbon Credit Generation

One of the most important distinctions for prospective project developers is that biochar production and carbon credit generation are not the same activity.

A facility may produce a useful biochar product without meeting the requirements of a carbon credit methodology.

Carbon certification introduces additional requirements related to eligibility, additionality, quantification, traceability, environmental safety, monitoring, and third-party assurance.

A project may encounter difficulties if:

• The biomass feedstock is not eligible

• Feedstock ownership or sourcing cannot be demonstrated

• Production data is incomplete

• Process emissions are not properly measured

• Biochar quality varies significantly between batches

• Carbon stability cannot be supported through laboratory testing

• The final use of the biochar cannot be documented

• The project cannot demonstrate additionality

• The technology does not generate audit-ready operating data

• Carbon ownership rights are unclear or disputed

Current biochar methodologies place considerable emphasis on the final destination of the biochar.

Production records must be connected to downstream records demonstrating where, when, and how the biochar was used.

Without reliable evidence of an eligible final use, biochar that may otherwise meet quality requirements might not generate carbon credits.

The Value of Developing a Biochar Carbon Credit Project

A well-structured carbon project can create value beyond the sale of the physical biochar product.

Carbon Revenue

Verified carbon credits may provide an additional revenue stream based on the net tonnes of carbon dioxide removed.

This revenue can improve project economics, support facility expansion, strengthen financing discussions, and provide income that is separate from biochar product sales.

Carbon revenue should not be treated as guaranteed revenue.

It depends on project eligibility, verified production, methodology requirements, credit prices, transaction costs, buyer demand, and the timing of issuance.

A feasibility study should test these variables before carbon revenue is incorporated into financial forecasts.

Improved Use of Biomass Residues

Biochar projects can create productive uses for biomass that may otherwise be burned, landfilled, left to decompose, or managed as a low-value residue.

This can create opportunities for:

• Agricultural operations

• Forestry companies

• Sawmills

• Municipalities

• Food processors

• Land managers

• Biomass aggregators

• Waste management companies

The value of the opportunity depends on whether the biomass is eligible, sustainably sourced, available at sufficient scale, and economically transportable.

Multiple Potential Revenue Streams

A biochar facility may generate value from several sources, including:

• Carbon credit sales

• Biochar product sales

• Biomass processing or tipping fees

• Renewable heat

• Electricity generation

• Syngas utilization

• Waste management services

• Agricultural products

• Construction materials

• Environmental remediation applications

Not every project will have access to all of these opportunities.

A strong commercial model identifies which revenue streams are realistic and avoids relying on speculative assumptions.

Environmental and Agricultural Benefits

Depending on the feedstock, production process, biochar properties, soil conditions, and application method, biochar may support:

• Water retention

• Nutrient retention

• Soil structure

• Drainage and aeration

• Agricultural resilience

• Reduced fertilizer requirements

• Land restoration

• Environmental remediation

These outcomes are not automatic and should be evaluated for the specific biochar product and intended application.

Stronger Investment Readiness

A project supported by a credible feasibility study, carbon model, monitoring plan, and certification strategy is better positioned for discussions with:

• Investors

• Lenders

• Government funders

• Technology providers

• Biomass suppliers

• Indigenous and local communities

• Agricultural partners

• Carbon credit buyers

• Corporate offtakers

Project development does not eliminate technical or commercial risk.

It identifies those risks, determines how they can be managed, and creates a defensible foundation for decision-making.

What Makes a Biochar Carbon Project Credible?

A credible project must connect the physical operation to a reliable carbon accounting system.

Several components are particularly important.

Feedstock Eligibility and Supply

The project must establish what biomass will be used, where it originates, how it is currently managed, who owns it, and whether it is eligible under the selected methodology.

The assessment should examine:

• Annual available volume

• Moisture content

• Seasonal variation

• Contamination risk

• Alternative uses

• Collection requirements

• Transportation distance

• Long-term supply agreements

• Sustainability requirements

• Chain-of-custody documentation

A project designed around an unreliable or ineligible feedstock supply may be unable to achieve its production or carbon removal forecasts.

Technology and Operating Performance

The production technology must be capable of consistently converting the selected feedstock into biochar while controlling energy use and emissions.

Important considerations include:

• Production capacity

• Operating temperature

• Residence time

• Process control

• Biochar yield

• Energy balance

• Air emissions

• Methane management

• Product consistency

• Data collection capabilities

• Equipment uptime

• Maintenance requirements

The project must also demonstrate that monitoring instruments are properly selected, calibrated, maintained, and capable of producing reliable information for verification.

Biochar Quality and Carbon Stability

The amount of creditable carbon removal depends partly on the characteristics of the biochar.

Laboratory testing may be required to evaluate parameters such as:

• Dry mass

• Organic carbon content

• Hydrogen-to-organic-carbon ratio

• Moisture

• Ash content

• Contaminants

• Carbon stability

• Product safety

• Physical properties

• Batch consistency

Testing requirements vary between standards and methodologies.

Sampling procedures, laboratory qualifications, testing frequency, and chain-of-custody requirements should be established before regular production begins.

Eligible End Use and Storage

Biochar must reach an eligible application that maintains its carbon storage potential.

Depending on the methodology, eligible uses may include:

• Agricultural soils

• Grasslands

• Landscaping materials

• Compost blends

• Construction products

• Concrete

• Asphalt

• Other approved long-term applications

Projects must maintain records connecting production batches with their final uses.

This evidence may include:

• Delivery records

• Customer declarations

• Invoices

• Application records

• Geographic information

• Photographs

• Product blending records

• Construction records

• Other proof of final use

Without reliable end-use documentation, otherwise eligible biochar may not generate credits.

Additionality

A carbon project must normally demonstrate that the credited carbon removal would not occur under the baseline scenario without carbon finance or another recognized project intervention.

Additionality requirements vary by program.

They may include:

• Regulatory surplus

• Investment analysis

• Common-practice analysis

• Barrier analysis

• Financial additionality

• Technology adoption analysis

Project economics should therefore be evaluated carefully and supported by reasonable, documented assumptions.

Environmental and Social Safeguards

A high-integrity carbon project must consider impacts beyond carbon.

The project may need to address:

• Air quality

• Water use

• Wastewater

• Noise

• Dust

• Feedstock sustainability

• Worker health and safety

• Community impacts

• Land rights

• Indigenous rights

• Biodiversity

• Applicable permits and regulations

The purpose of carbon certification is not simply to maximize credited tonnes.

It is to support credible climate outcomes without creating unacceptable environmental or social harm.

Monitoring, Reporting, and Verification

Monitoring, reporting, and verification, commonly referred to as MRV, is the evidence system behind a carbon project.

MRV may include:

• Feedstock receipts and sourcing records

• Feedstock moisture measurements

• Production volumes

• Operating temperatures

• Fuel and electricity use

• Biochar yields

• Laboratory reports

• Transportation records

• Emission measurements

• Biochar sales and distribution records

• End-use evidence

• Equipment calibration

• Data quality controls

• Corrective-action procedures

The evidence trail should begin before the first crediting period.

Attempting to reconstruct incomplete records after production has occurred can create significant verification risk.

PeriCarbon’s project development approach therefore treats MRV as part of the facility’s operational design rather than as an administrative exercise added later.

Biochar Carbon Standards and Methodologies

Several carbon programs have developed pathways for biochar carbon removal.

Examples include:

• Puro.earth’s Biochar Methodology

• Verra’s VM0044 Biochar Utilization in Soil and Non-Soil Applications

• Isometric’s Biochar Production and Storage Protocol

• Other regional or program-specific carbon standards

The appropriate pathway depends on:

• Project location

• Feedstock type

• Production technology

• Facility scale

• End use

• Carbon durability

• Additionality

• Buyer expectations

• Monitoring capabilities

• Commercial strategy

Different standards apply different rules for eligibility, carbon persistence, monitoring, testing, issuance, and verification.

Methodology selection should therefore occur early, before equipment, contracts, data systems, and end-use arrangements become difficult to change.

The Biochar Carbon Project Development Process

A strong biochar carbon project typically progresses through several stages.

Stage 1: Initial Project Screening

The initial screening determines whether there appears to be a realistic carbon development opportunity.

This stage reviews:

• Proposed feedstock

• Technology

• Project location

• Production status

• Intended end use

• Operating scale

• Ownership structure

• Available project information

The objective is to identify major eligibility barriers before undertaking a detailed study.

Stage 2: Feasibility Study

The feasibility study examines whether the project can work technically, financially, operationally, and under an applicable carbon methodology.

A comprehensive assessment should address:

• Feedstock eligibility and supply

• Technology performance

• Expected biochar production

• Preliminary carbon removal potential

• Applicable methodologies

• Additionality

• End-use eligibility

• MRV requirements

• Environmental considerations

• Project development costs

• Validation and verification costs

• Potential carbon revenue

• Key risks and data gaps

The purpose of this stage is not to guarantee carbon credits.

It is to provide a decision-ready foundation for determining whether the project should proceed.

Stage 3: Methodology and Certification Strategy

Once the opportunity has been evaluated, the project selects its preferred standard, methodology, registry, verification pathway, and crediting structure.

This stage should clarify:

• Applicability conditions

• Project boundary

• Baseline scenario

• Additionality requirements

• Monitoring requirements

• Laboratory requirements

• End-use requirements

• Crediting period

• Verification frequency

• Registry and issuance costs

Stage 4: Project Design and Documentation

The project design translates the physical operation into a formal carbon project.

Documentation may include:

• Project description

• Ownership and carbon rights

• Baseline assessment

• Additionality demonstration

• Project boundary

• Quantification approach

• Monitoring plan

• Data management procedures

• Quality assurance procedures

• Environmental and social safeguards

• Risk assessment

• Stakeholder information

The exact documentation will depend on the selected program.

Stage 5: MRV System Development

The project must establish systems for collecting, storing, reviewing, and protecting the information required for future verification.

Whenever possible, MRV requirements should be incorporated directly into production systems and operating procedures.

This may involve:

• Meters and sensors

• Laboratory testing schedules

• Digital records

• Batch identifiers

• Customer documentation

• Chain-of-custody systems

• Internal quality controls

• Data backup procedures

• Staff training

Stage 6: Validation and Registration

An approved independent validation and verification body reviews the project design.

The reviewer assesses whether the project complies with the selected standard and methodology.

Questions, findings, or corrective actions may need to be addressed before registration can be completed.

Stage 7: Implementation and Monitoring

The project operates according to its registered design and monitoring plan.

During this stage, the project collects evidence covering:

• Feedstock

• Production

• Emissions

• Energy consumption

• Biochar quality

• Distribution

• Final use

Stage 8: Verification

An independent verifier reviews the monitoring report and supporting evidence.

The verifier determines whether the reported net carbon removal is accurate, complete, conservative, and compliant with the methodology.

Stage 9: Credit Issuance

Following successful verification and program approval, eligible net removals may be issued as carbon credits or carbon removal certificates.

Credits can then be sold, transferred, or retired according to the rules of the applicable registry and the terms of any buyer agreement.

How to Get Started

A prospective biochar project developer should begin by answering several foundational questions:

1. What biomass will be used?

2. How much biomass is available each year?

3. Where does the biomass come from?

4. How is the biomass currently managed?

5. Has a production technology been selected?

6. Is the facility already operating?

7. What data does the technology collect?

8. How much biochar is expected to be produced?

9. Has the biochar been laboratory tested?

10. Where will the biochar be used?

11. Can its final use be documented?

12. Who owns the biomass, biochar, and carbon rights?

13. What permits are required?

14. What revenue streams are expected?

15. Is carbon finance necessary for the project to proceed or expand?

Even preliminary answers can help determine whether the project is ready for a feasibility assessment.

How PeriCarbon Supports Biochar Project Development

PeriCarbon supports organizations seeking to evaluate and develop credible biochar carbon projects.

Our objective is to help project owners understand what is credible, what remains uncertain, and what must be strengthened before advancing into certification.

Building a Credible Carbon Asset

Biochar has the potential to connect biomass management, durable carbon removal, renewable energy, agriculture, and the circular economy.

Realizing that potential requires more than producing a carbon-rich material.

It requires a project that can demonstrate eligible feedstock, controlled production, accurate carbon accounting, reliable monitoring, environmentally responsible end use, and independent verification.

Early project development can help prevent significant investments from being made around weak assumptions, incomplete data systems, unsuitable methodologies, or unrealistic carbon revenue expectations.

For organizations considering a biochar facility or evaluating the carbon potential of an existing operation, the first step is a structured feasibility assessment.
