Biochar Market

Biochar sells twice from the same tonne: once as a soil product and once as a carbon removal credit, and the credit is now worth more than the char. Douglas Insights values the biochar market at USD 682.0 million in 2025 and expects USD 3.10 billion by 2035, compounding at 16.35%. The estimate is built from the bottom up: roughly 1.1 million tonnes of biochar produced commercially in 2025, at an average realised value of USD 620 per tonne combining product sales into soil amendment, construction materials, animal feed and filtration with revenue from carbon removal credits, triangulated against producer capacity, carbon removal registry records and end market data. Production grows 18.0% a year as carbon removal buyers and agricultural demand expand, while value per tonne eases 1.4% a year as production scales and credit prices soften from early premium levels. This study sits within our agricultural inputs coverage and follows the published Douglas Insights methodology.

Why did biochar become the leading source of delivered carbon removal?

Because it is one of the few ways to remove carbon dioxide from the atmosphere that works today, at meaningful scale, with verifiable permanence and relatively low cost. Biochar is made by heating biomass such as crop residues, forestry waste or manure in the absence of oxygen, a process called pyrolysis, which converts much of the carbon the plants absorbed from the air into a stable, charcoal like solid. When that biochar is added to soil or incorporated into materials such as concrete, a large share of its carbon remains locked away for centuries rather than returning to the atmosphere as the biomass would have when it decomposed. Companies seeking to offset hard to eliminate emissions have become major buyers of carbon removal, and among durable removal methods biochar has delivered far more verified tonnes than alternatives such as direct air capture, which remains expensive and small scale. Carbon removal registries have developed methodologies for measuring and verifying biochar removal, and credit revenue has become a significant part of biochar project economics, allowing producers to sell biochar at lower prices to farmers and other users. The exclusive chapter of this report models the combined economics of product and credit revenue, since both determine which projects are viable.

What does this market include?

This study covers commercially produced biochar and the revenue it generates. Soil amendment and agriculture covers biochar applied to farmland, horticulture and landscaping, including the bagged soil improvers sized in the Lawn and Garden Consumables Market report, to improve soil structure, water retention and nutrient retention, the largest end use. Carbon removal credit revenue covers the revenue producers earn by selling verified carbon removal credits representing the carbon stored in their biochar. Construction materials and concrete additives cover biochar incorporated into concrete, asphalt and building materials, where it both stores carbon and can modify material properties. Animal feed, filtration and other uses cover biochar used as a feed additive, in water and air filtration, in composting and in other applications. Charcoal for cooking and fuel, activated carbon produced for industrial purification, biomass energy without biochar output, and pyrolysis equipment sold separately sit outside the boundary. Value is measured at revenue from biochar sales and associated carbon credits.

How permanent is the carbon in biochar?

More permanent than most nature based carbon storage, though not as absolute as geological storage, and the scientific estimates of that permanence underpin the whole credit market. Biochar’s carbon is in a stable, aromatic form that resists microbial decomposition, so it breaks down very slowly. Research indicates that a large fraction of the carbon in well produced biochar persists for hundreds to thousands of years in soil, with the stability depending on production temperature and feedstock, higher temperatures generally producing more stable biochar. This durability distinguishes biochar from carbon stored in trees or soil organic matter, which can be released by fire, harvest or changes in land use, and is why buyers seeking durable removal favour it. Carbon removal methodologies account for this by crediting only the portion of carbon expected to remain stable over a defined period, applying conservative decay assumptions, and requiring testing of biochar properties. Debate continues about the precise decay rates and how to measure them, and quality varies considerably between producers, which is why certification and verification matter so much to credit value. For this market, the credibility of permanence claims directly affects the price buyers will pay for biochar removal credits.

What drives demand?

The first driver is corporate carbon removal purchasing. Technology companies and other corporations with net zero commitments buy durable carbon removal, and biochar is currently one of the most available and affordable options, making credit revenue a major growth driver.

The second driver is soil health and agriculture. Biochar can improve soil water retention and nutrient efficiency, particularly on poor soils, supporting demand from farmers, horticulture and landscaping; it competes for the same nutrient efficiency budget as the coated and inhibitor-treated products sized in our Specialty Fertiliser Coatings Market report, which grows 6.90% a year to USD 3.65 billion in 2035.

The third driver is waste biomass management. Agricultural and forestry residues that would otherwise be burned or left to decompose can be converted to biochar, offering a use for waste streams and avoiding emissions from open burning.

The fourth driver is regulatory recognition. Frameworks such as the European Union’s certification framework for carbon removals are establishing rules that could integrate biochar removal into policy and compliance markets.

What restrains the market?

Three restraints are modelled. Economics and credit dependence are the first: biochar production is often not profitable on product sales alone, so projects depend on carbon credit revenue, whose price and demand are uncertain and concentrated among a limited number of buyers. Quality and verification are second: biochar quality varies with feedstock and process, poorly made biochar may be less stable or contain contaminants, and credible measurement, reporting and verification add cost and complexity. Agronomic variability is third: the benefits of biochar in soil vary widely with soil type, climate and application method, so farmers see inconsistent results, which limits willingness to pay for biochar as a product.

Which end uses carry the revenue?

Soil amendment and agriculture lead with 44% of 2025 revenue, USD 300.1 million, the largest end use for biochar product sales, and the highest prices per tonne come from protected horticulture, where substrate costs are small against the controlled-environment capital sized in our Commercial Greenhouse Automation Market report, USD 2.89 billion in 2025. Carbon removal credit revenue holds 30%, USD 204.6 million, and grows slowest at 11.82% a year to USD 625.2 million, because the tonnes rise fast while the price per tonne softens from early premium levels. Construction materials and concrete additives account for 12%, USD 81.8 million, and grow fastest at 23.25% to USD 661.6 million, overtaking credit revenue before 2035. Animal feed, filtration and other uses contribute 14%, USD 95.5 million, growing 15.30% to USD 396.5 million. Soil amendment grows 16.79% to USD 1.42 billion and stays the largest end use throughout. Each end use is modelled through 2035 by region.

Which biochar segment grows fastest?

Construction materials and concrete additives grow fastest, at 23.25% a year against the market’s 16.35%, from USD 81.8 million to USD 661.6 million, and by 2035 they are worth more than carbon credit revenue. The reason is that concrete is the one outlet where biochar’s two revenue lines stop competing: a tonne mixed into a slab is stored somewhere a verifier can point to for the life of the structure, it does not depend on a farmer seeing an agronomic benefit, and the buyer is a materials company solving its own emissions problem rather than an offset purchaser. Soil amendment stays the largest end use throughout and grows 16.79%, feed, filtration and other uses 15.30%, and credit revenue slowest at 11.82% a year, because the model already carries value per tonne easing 1.4% a year as durable removal stops being scarce.

Where is biochar produced?

North America leads with 34% of 2025 revenue, USD 231.9 million, growing 15.1% a year, reflecting large biomass resources, active carbon removal buyers and numerous producers. Europe holds 30%, USD 204.6 million, and grows at 17.4%, supported by established biochar standards, strong carbon removal policy development and producers in Germany, the Nordic countries and elsewhere. Asia Pacific holds 26%, USD 177.3 million, at 16.4%, with large agricultural residue resources in China and India and growing interest in biochar for both soil and carbon removal. Latin America contributes USD 34.1 million at 17.0% on abundant biomass, Africa USD 20.5 million and grows fastest at 18.0% from a small base, often in smallholder and development linked projects, and the Middle East USD 13.6 million at 15.0%. Six regional models sum to the global figure, with country tables in the Excel model.

Who produces biochar?

The market consists of many producers, from large industrial facilities to small and farm scale operations. Carbon removal focused companies have built biochar projects to generate credits, often in partnership with biomass suppliers and supported by offtake agreements with corporate buyers. Equipment makers supply pyrolysis units used by producers, and some operate their own biochar projects. Carbon removal registries and marketplaces, such as those that develop methodologies and verify biochar removal, play a central role in the market’s structure, and large corporate buyers and buyer coalitions shape demand through their purchasing. Agricultural suppliers distribute biochar products to farmers and horticulture. Because the industry is young and fragmented, consolidation and the emergence of larger producers are expected. The competitive chapter profiles leading producers by capacity, feedstock, certification, credit sales and end markets.

How is biochar priced?

Average realised value is USD 620 per tonne in 2025, combining product and credit revenue in a way that varies greatly by project. Biochar sold as a soil amendment or material may fetch from modest to relatively high prices depending on quality, market and whether it is blended with other products. Carbon removal credits for biochar trade at prices per tonne of carbon dioxide removed that are well above those of conventional avoidance offsets, reflecting durability, and each tonne of biochar can represent more than two tonnes of carbon dioxide removed depending on carbon content, so credit revenue per tonne of biochar can be substantial. Early credit prices were high as buyers sought scarce durable removal, and prices are expected to moderate as supply grows, which is the main reason for the slightly negative value leg. Long term offtake agreements with corporate buyers provide revenue certainty for new projects. The pricing chapter publishes product and credit price bands by end use and certification level.

How do the scenarios diverge by 2035?

The base case carries 18.0% growth in production and a 1.4% annual decline in value per tonne for a 16.35% revenue CAGR and USD 3,099.8 million in 2035. The credit-slump scenario, in which corporate removal demand stalls and credit prices fall, sets the legs at 11.0% and minus 4.0%, landing near USD 1,280 million. The compliance-integration scenario, in which carbon removal is integrated into regulated markets and agricultural adoption grows, sets them at 23.0% and 0.0%, carrying the market past USD 5,410 million. Each 1-point change in production growth moves the 2035 figure by roughly USD 270 million. Confidence is low given dependence on carbon credit demand and the early stage of the market.

Which rules and standards apply?

Three layers matter. Carbon removal certification comes first and is central to value: methodologies from carbon removal registries and emerging government frameworks define how biochar removal is measured, what permanence is credited, and how projects are verified, determining whether credits can be sold and at what price. Product standards are second: biochar quality standards specify limits on contaminants such as heavy metals and polycyclic aromatic hydrocarbons, carbon content and stability, which govern use in agriculture and materials. Agricultural and fertiliser regulation is third: using biochar in soil, feed or fertiliser products is subject to agricultural product and waste regulation, which in some jurisdictions restricts feedstocks or requires registration. The regulatory chapter maps these requirements by jurisdiction.

What separates high value biochar projects from the rest?

Biochar projects vary enormously in quality and value, and the features that distinguish the best projects explain where the market is heading. High value projects use consistent, sustainable feedstocks that do not compete with food or cause harmful land use change, typically genuine residues and wastes. They operate pyrolysis at controlled high temperatures that produce stable biochar, capture and use the process energy rather than wasting it, and control emissions during production. They test their biochar rigorously for carbon content, stability and contaminants, obtain certification from credible registries, and track where their biochar is applied so that storage can be verified. And they place biochar into end uses where it delivers additional value, such as soils that benefit from it or materials that incorporate it durably. Projects lacking these features face difficulty selling credits to discerning buyers and may produce biochar of uncertain quality. As buyers become more sophisticated and scrutiny of carbon credits increases, value is concentrating in high quality, well verified projects, and the model reflects growth weighted toward such producers.

Douglas Exclusive: the biochar project economics model

This report models, by feedstock, scale and region, production cost including biomass, pyrolysis and certification, biochar yield and carbon content, credit revenue at varying credit prices, product revenue by end use, and resulting project margins, identifying which configurations are viable at each credit price and converting project pipelines into production and revenue by end use and region. Licence holders receive it as a maintained tab in the Excel model.

Methodology and receipts

The model is built bottom-up from tonnes: commercial biochar production capacity by region and scale, feedstock availability, carbon removal credit issuance and sales from registries, end use demand, and realised product and credit prices from producer and market disclosures, with cooking and fuel charcoal, industrial activated carbon, biomass energy without biochar and standalone equipment sales excluded. Every figure carries a numbered source and a confidence grade in the fact sheet above, and the working model ships with every licence. The next scheduled review of this study is September 2027.
