Imagine a project promoter in Punjab sitting with quotations for a biochar plant.
He has access to crop residue. Land is available. The machinery supplier is promising continuous production. The financial model looks attractive because it includes revenue from biochar sales and carbon credits.
On paper, the project appears ready.
Then the investor asks a simple question:
“Who is going to buy 10 or 20 tonnes of biochar from us every day?”
The room becomes quiet.
This is where many biomass projects become difficult. Setting up machinery is only one part of the business. A commercially successful biochar plant needs 4 things working together:
India has strong potential for biochar because the country generates large quantities of agricultural residues from crops such as rice, wheat, cotton, sugarcane, maize and several plantation crops. At the same time, international companies are increasingly purchasing durable carbon removals from projects that convert biomass into stable biochar.
This combination has created a new business opportunity.
But biochar should not be treated as a commodity where a plant can simply produce first and find customers later.
Before investing, the promoter needs to understand the biochar plant market in India, actual demand, potential buyers, product specifications, carbon credit opportunities and offtake structure.
Biochar is produced by heating biomass under limited oxygen conditions, generally through pyrolysis or gasification.
Instead of allowing biomass to completely burn, part of the carbon contained in the biomass is converted into a stable carbon-rich solid material.
This creates 2 possible commercial opportunities.
The first is selling physical biochar.
The second is generating verified carbon removal from the carbon stored in the biochar.
These 2 markets are related, but they are not the same.
A farmer may purchase biochar because it helps improve certain soil properties.
A compost company may purchase it as an ingredient.
A carbon buyer may pay for verified tonnes of carbon dioxide removed from the atmosphere and stored through biochar.
This distinction is important while preparing a feasibility study or DPR.
A plant may produce 5,000 tonnes of biochar annually, but that does not mean it automatically produces 5,000 carbon credits.
Carbon removal depends on feedstock, production process, stable carbon content, lifecycle emissions, end use, methodology and verification.
India has one major advantage – biomass availability.
Agricultural residues are generated across large farming belts every year. Depending on the region, feedstock can include:
However, availability on paper and availability at the plant gate are 2 very different things.
A feasibility study should calculate how much biomass can actually be collected within a practical transportation radius.
For example, assume a plant requires 50 tonnes of biomass per day and operates for 300 days per year.
Annual biomass requirement becomes:
50 tonnes x 300 days = 15,000 tonnes per year
The promoter therefore needs considerably more than 15,000 tonnes of theoretical residue availability because some material may already be used for fodder, fuel, briquettes, pellets, boilers or other applications.
Seasonality also matters.
A crop residue may be available heavily for only 2 or 3 months, while the biochar plant may need to operate throughout the year.
This means feedstock storage and multi-feedstock capability can become important parts of project design.
The physical biochar market is developing across agriculture, horticulture, soil improvement and selected industrial applications.
Agriculture is currently one of the easiest markets for investors to understand, but it is not always the easiest market to monetise.
Farmers are generally price sensitive.
A biochar project cannot assume that farmers will purchase large quantities simply because biochar has environmental benefits.
The farmer usually wants a measurable commercial outcome.
That may include:
Performance may vary depending on soil conditions, crop, biochar characteristics and application rate.
Therefore, pilot testing is important.
Selling biochar at ₹X per kilogram based only on internet quotations can create a weak DPR. Retail prices, packaged biochar prices and bulk industrial prices can be completely different.
A 1 kg packaged gardening product and a 20 tonne bulk truckload should never be treated as the same market.
A biochar plant can potentially target several categories of buyers.
Large farms and progressive farmers can become users where biochar provides measurable agronomic benefits.
However, bulk adoption generally needs field demonstrations.
A project should ideally identify crops where biochar application has a clear economic reason.
FPOs can create a more scalable route than selling separately to hundreds of farmers.
One FPO may represent hundreds or even thousands of farmers.
This can reduce customer acquisition and distribution costs.
Nurseries, greenhouse operators, floriculture projects and horticulture businesses may use biochar in specialised growing media.
These buyers may accept higher value products where performance is established.
Biochar can potentially be blended into compost or other soil improvement products.
For this market, the buyer may focus on parameters such as:
Companies already selling soil conditioners, organic inputs or biological products may offer a distribution channel.
Instead of building a new farmer network, the biochar producer can potentially become a B2B supplier.
This is becoming one of the most important buyer categories.
Here, the project is not simply selling physical biochar.
The commercial product becomes verified carbon dioxide removal.
The traditional biochar model depended mainly on selling the physical material.
The newer model can have 2 revenue streams:
Revenue 1 – Physical biochar sale
Revenue 2 – Verified carbon removal
International carbon buyers are showing increasing interest in biochar because the carbon stored in appropriately produced and used biochar can remain stable for long periods.
Several large technology companies have already entered long-term carbon removal agreements involving Indian biochar projects.
One publicly announced India-related agreement involved 100,000 tonnes of biochar carbon removal through 2030.
Another Indian project announced a carbon removal agreement covering more than 100,000 tonnes over approximately 3 years and plans involving around 18 industrial reactors.
Another Indian industrial biochar project announced an approximately 180,000 tonne carbon removal offtake.
These numbers show that India is no longer only discussing biochar at laboratory scale.
Commercial carbon removal projects are being developed.
But these examples should not be misunderstood.
A newly established 5 TPD or 10 TPD plant should not assume that Google, Microsoft or another multinational company will automatically become its buyer.
Large carbon buyers normally expect strong monitoring, verification, traceability and long-term delivery capability.
This is one of the most common mistakes in biochar feasibility reports.
Suppose the plant produces:
3,000 tonnes of physical biochar per year
The promoter cannot simply multiply 3,000 tonnes by a carbon credit price.
Carbon credits are generally measured in tonnes of carbon dioxide equivalent removed.
The amount depends on several factors, including:
In August 2026, one market assessment for Indian biochar carbon removal was around USD 130 per tonne of CO2 equivalent.
This should be viewed as a market reference, not guaranteed project revenue.
Carbon removal prices can vary considerably depending on quality, delivery year, contract length, project credibility, methodology and buyer requirements.
The financial model should therefore contain at least 3 cases:
Case 1 – Physical biochar revenue only
Case 2 – Physical biochar plus conservative carbon revenue
Case 3 – Physical biochar plus contracted carbon offtake
This gives the investor a better understanding of project risk.
A promoter should not wait until production begins and then ask:
“How can we generate carbon credits?”
By that stage, it may already be too late to reconstruct some of the required information.
Carbon removal programmes can require detailed records related to biomass procurement, transportation, plant performance, energy consumption and biochar application.
A project may need traceability similar to:
Farm residue collection – Transport – Biomass storage – Pyrolysis batch – Biochar testing – Dispatch – Final application – Monitoring – Verification – Carbon credit issuance
If the plant produces 10 tonnes of biochar today, the project may need to show exactly where the biomass came from and where the final biochar went.
This makes digital recordkeeping important.
India has developed the Carbon Credit Trading Scheme and approved multiple offset methodologies.
As of 2026, around 12 approved offset methodologies had been listed across areas including energy, agriculture, forestry, industrial processes and waste management.
However, investors should be careful about directly assuming that every biochar plant can generate credits through India’s domestic carbon market.
A dedicated and clearly applicable biochar methodology should be confirmed before including domestic carbon credit revenue in a bankable DPR.
At present, many Indian biochar projects exploring carbon removal are evaluating international voluntary carbon market frameworks.
Therefore, carbon revenue should be treated as a separate project development workstream.
An offtake agreement is an arrangement where a buyer agrees to purchase future production or future verified carbon removals under agreed commercial conditions.
For a biochar project, there can be 3 main types.
A buyer agrees to purchase physical biochar.
The contract may specify:
For example, a compost company may agree to purchase 200 tonnes per month.
That gives the project annual visibility for approximately:
200 x 12 = 2,400 tonnes
This can significantly strengthen the physical sales side of the project.
A carbon buyer agrees to purchase future verified carbon removals.
The agreement may define:
This type of contract can provide stronger revenue visibility than spot carbon credit sales.
A project may have one buyer for physical biochar and another buyer for carbon removal.
This can be an attractive structure.
For example:
A soil amendment company takes the physical material.
A carbon removal buyer purchases the verified climate benefit.
The project therefore does not need one organisation to purchase both products.
Consider a proposed plant located near an agricultural cluster in North India.
The promoter plans to process crop residues collected within approximately 50 to 100 km of the facility.
The proposed feedstock requirement is 40 tonnes per day.
Assume the plant operates for 300 days annually.
Annual biomass requirement becomes:
40 tonnes x 300 days = 12,000 tonnes
If the process generates approximately 25 percent biochar by mass, the theoretical annual biochar output could be approximately:
12,000 x 25 percent = 3,000 tonnes
The promoter initially plans to sell all 3,000 tonnes to farmers.
That looks simple on Excel.
But selling 3,000 tonnes means selling approximately 250 tonnes every month.
If one farmer purchases 2 tonnes annually, the company could require around:
3,000 / 2 = 1,500 farmer customers
That creates a major sales and distribution challenge.
Instead, the project restructures the market strategy.
It targets:
Now the physical market becomes more diversified.
At the same time, the project evaluates whether its production process and final applications can qualify under an accepted carbon removal methodology.
This is a much stronger commercial model than producing 3,000 tonnes first and hoping the market appears later.
A serious carbon buyer will usually look much deeper than the machinery brochure.
The buyer may evaluate whether the project represents genuine additional carbon removal.
Important areas can include:
This makes technology selection important.
A lower cost reactor is not necessarily the better reactor if it cannot provide stable process control or appropriate monitoring data.
There is no universal percentage.
However, an investor should ideally avoid building a plant where 100 percent of output remains uncommitted.
For example, if planned production is 5,000 tonnes per year, the project may try to develop:
A project with 3 serious buyers is generally commercially safer than a project depending entirely on 1 customer.
Buyer concentration should therefore be included in the risk analysis.
Biochar looks attractive because it combines waste utilisation, agriculture and carbon removal.
But projects still face commercial risks.
Biomass that appears to be waste today can become valuable tomorrow.
Pellet plants, briquette plants, boilers and CBG projects may compete for the same feedstock.
Low-density agricultural residue can become expensive to transport.
A 150 km supply radius may materially change project economics compared with a 30 km or 50 km radius.
Some crop residues may only be available during a limited harvesting period.
Storage infrastructure may therefore become necessary.
Physical biochar markets may take time to develop.
Agricultural customers usually want trial results before adopting a new input.
Carbon removal revenue depends on methodology, verification and market demand.
Credit issuance can take time.
Biochar quality can vary if reactor conditions are inconsistent.
A project designed only around maximum biomass throughput may fail to produce the specification demanded by premium buyers.
A proper biochar feasibility study should not start with machinery quotations.
It should start with the market.
At minimum, the promoter should evaluate:
The final DPR should be prepared only after these assumptions are reasonably validated.
A commercial biochar plant may require multiple approvals depending on its capacity, process, fuel system, emissions, land location and state.
Typical project planning may involve:
The exact approval requirement depends on the proposed technology and the concerned State Pollution Control Board.
Therefore, land purchase and machinery ordering should ideally happen after basic regulatory feasibility has been checked.
Biochar can become an attractive business in India where 4 conditions are available together.
First – Low cost and reliable biomass.
Second – Appropriate conversion technology.
Third – Real physical product demand.
Fourth – A credible carbon removal pathway.
A project becomes much weaker when the business plan depends entirely on carbon credits.
A stronger plant should ideally remain commercially understandable even if carbon revenue is delayed.
Carbon removal income can then improve project returns instead of becoming the only reason the plant survives.
The biochar plant market in India is moving beyond small agricultural demonstrations.
International carbon removal contracts involving Indian projects exceeding 50,000 tonnes, 100,000 tonnes and even 180,000 tonnes of future carbon removal indicate that serious capital and corporate buyers are entering this sector.
At the same time, those numbers should not make new investors overconfident.
A successful biochar business starts much earlier than plant commissioning.
The promoter needs to answer 5 questions:
If these questions are answered before machinery procurement, the project has a much stronger foundation.
If they are answered after commissioning, the promoter may own an operating plant without owning a reliable market.
For investors planning a biochar project in India, the best first step is therefore not machinery selection.
It is a feedstock, market, buyer, carbon eligibility and offtake feasibility study.
Green Permits can assist with market assessment, buyer identification, feedstock analysis, feasibility study, DPR preparation, plant capacity planning, environmental approvals and project implementation strategy.
