Explore Emerging Biochar Startups to Watch in 2026

We hand-picked startups to showcase in this report by filtering for their technology, founding year, location, funding, and other metrics. These emerging biochar solutions range from feedstock and clean fuel to seed coating and soil enhancer.

1. Miraia – Bio-based Oil

  • Founding Year: 2023
  • Location: Toulouse, France

Miraia is a French startup that produces bio-oil through a pyrolysis process that thermally decomposes local, sustainably sourced wood biomass in a low-oxygen environment. This method yields biochar, syngas, and bio-oil, with bio-oil serving as a renewable green fuel and a substitute for petrochemical derivatives.

By storing carbon as biochar for long-term storage, the process effectively uses biomass components without producing any fumes or odors and removes carbon dioxide. Thus, Miraia lessens dependency on fossil fuels and promotes sustainable practices by turning biomass into useful products.

2. CO2 Sync – Forest Waste to Biochar

  • Founding Year: 2024
  • Location: Charleston, Utah, USA

US-based startup CO2 Sync develops Carbo CAP-TEC technology that converts forest waste into biochar and renewable electricity. Its Carbo-FORCE pyrolysis reactor uses an auto-thermal process to transform wood chips into biochar and flue gas, while Durr’s Cyplan generator captures the released energy to produce power.

The process achieves high carbon purity in biochar and prevents CO₂ emissions. This way, it supports reforestation, lowers emissions, and delivers sustainable electricity for homes and industries.

3. Biochar Byte – Biomass Inventory Platform

  • Founding Year: 2024
  • Location: Pune, India

Biochar Byte is an Indian startup that develops industrial-scale biochar solutions to transform agricultural biomass into carbon-rich material through pyrolysis. It creates sustainable packaging raw materials while restoring soil health and sequestering carbon.

The startup integrates geospatial imaging and technology-driven logistics to collect and process crop residues, prevent open-field burning, and reduce greenhouse gas emissions. Its biochar enhances soil fertility, water retention, and microbial activity, while also serving as a long-term carbon sink that remains stable in soil.

In addition, the process generates renewable by-products such as bio-oil and syngas while contributing to circular energy systems. By combining biochar production with carbon credit generation, large-scale plantations, and digital supply chain platforms, Biochar Byte provides smallholder farmers with additional income, builds resilience against climate variability, and supports sustainable agriculture.

4. Exomad Green – Soil Enhancer

  • Founding Year: 2023
  • Location: Santa Cruz, Bolivia

Exomad Green is a Bolivian startup that produces biochar using the pyrolysis of recycled hardwood residues. Thus, it turns waste into a stable form of carbon stored in soil.

This biochar enriches the land by improving nutrient retention, water holding capacity, and overall soil structure. Its porous surface creates a habitat for beneficial microbes, which enhance nutrient cycling and support healthy plant growth.

It also regulates soil pH and reduces nutrient loss to make fields more productive over time. By using biochar, farmers and land managers achieve higher yields, stronger crops during drought, and healthier soils for the long term.

5. BCHAR – Biochar Production Automation

  • Founding Year: 2023
  • Location: Zurich, Switzerland

Swiss startup BCHAR uses pyrolysis technology to develop autonomous biochar production systems that convert agricultural waste into biochar. Each unit integrates pre-processing, pyrolysis, post-processing, and packaging into one solution. The design reduces downtime, lowers maintenance costs, and simplifies commissioning on-site.

Also, built-in automation limits manual intervention, improves safety, and eases operation. Moreover, the system recovers excess heat for energy reuse, supporting efficiency. Likewise, its integrated measurement, reporting, and verification (MRV) software tracks carbon removal and credit generation.

6. Seedrise – Seed Coating

  • Founding Year: 2023
  • Location: Berlin, Germany

German startup Seedrise offers a biochar seed coating to embed nutrients, biostimulants, and biorepellents into seeds. The coating releases these inputs gradually to enhance nutrient efficiency and reduce fertilizer use. It also stores and supplies water and nutrients during sowing, which improves soil health and reduces leaching.

Farmers benefit through lower input costs, less labour, and reduced carbon dioxide emissions.

7. SynoProtein – Biochar Feedstock

  • Founding Year: 2023
  • Location: Tonsberg, Norway

Norwegian startup SynoProtein develops a carbon-negative process that transforms forestry residues into single-cell proteins (SCP) and biochar. The process combines thermochemical pyrolysis with biological fermentation to create sustainable feed ingredients.

Biochar enriches animal feed with improved nutrition while locking carbon in a stable form. This approach adds value to low-grade by-products and reduces emissions from feed production. Aquaculture and agriculture benefit from reliable proteins and nutrient-rich biochar that support sustainable farming practices.

8. MacroCarbon – Seaweed Sequestration

  • Founding Year: 2023
  • Location: Gran Canaria, Spain

Spanish startup MacroCarbon develops large-scale seaweed aquaculture systems to produce sustainable biomass. Its integrated cultivation model uses pelagic seaweed and offshore farming infrastructure to increase biomass yields into biochar.

 

 

This solution captures atmospheric carbon, absorbs excess ocean nutrients, and generates flexible biomass for fuels, plastics, and chemicals. It reduces reliance on fossil-based resources and land farming while supporting resilient coastal economies.

9. Bamboo Genie – Clean Fuel

  • Founding Year: 2023
  • Location: Pune, India

​Bamboo Genie is an Indian startup that develops bamboo-based biochar to enrich soil and increase agricultural productivity. The company uses bamboo’s high cellulose content to create biochar with greater carbon retention.
