For buyers
Carbon removal you can trace to its source
Durable removals from one plant in southern Sweden, certified under the Rainbow Standard and backed by lab data for each credited batch.
01 / What you get
Four things behind every tonne
Certified removals
Issued under the Rainbow Standard at the 100-year permanence tier and recorded in its public registry, so your claim points to a specific project.
Measured biochar
Each production batch behind our removals is analysed by Eurofins, an independent lab, and reviewed by the Rainbow verifier.
One traceable source
One plant and one feedstock: screenings from Skånefrö’s seed production.
Benefits beyond carbon
In farmland, biochar can help soil hold water and nutrients, and part of the process heat goes into district heating.
02 / Fit
A good fit if this sounds like your organisation
- You have a net-zero or climate-positive target and emissions you cannot yet avoid.
- You want durable removals in your portfolio, not avoided emissions somewhere else.
- You want a European producer with a plant you can point to on a map.
How buying works
- Tell us what you need. Volume, timing and any reporting framework you follow. A rough figure is enough to start.
- Get a proposal. We reply with availability, price and the verification documents behind the removals.
- Receive certified removals. Removals are issued under the Rainbow Standard and documented in its public registry.

Project summary
- Seller
- ECOERA AB, org.nr 556719-4922
- Method
- Biochar carbon removal (pyrolysis of seed-screening pellets)
- Feedstock
- Pelletised seed-screening residues from Skånefrö’s seed production
- Baseline
- Without the project, the pellets are burned in a furnace for heat
- Process
- Pyrolysis at about 500 °C, about 100 minutes
- H/Corg ratio
- 0.186 (2024 batch) and 0.195 (2025 batch), Rainbow verification based on Eurofins analyses
- Removal standard
- Rainbow Standard, project RIV-2025-PROJ-118
- Permanence tier
- 100 years under the Rainbow methodology (H/Corg below 0.7)
- Biochar certification
- European Biochar Certificate for individual batches; the certificate is held by Skånefrö AB
- Production site
- ECOERA Millennium 1, Hammenhög, Skåne, Sweden
- Operator
- Bioagro Energy Österlen AB runs the plant; ECOERA manages the carbon removal. Skånefrö owns about a third of ECOERA
- Technology
- PYREG P500 and P1500 pyrolysis systems
- Carbon storage
- Applied to soil, mostly in Sweden: farmland and green spaces, football pitches, building foundations
- Track record
- Biochar carbon removal since 2009; 1,530 Puro.earth credits for removals from 2019 to 2024, all retired

Measured values against their limits
Molar ratio of hydrogen to organic carbon. Lower means more stable carbon; the limit for certified biochar is 0.7. The 2024 batch measured 0.186.
SourcesRainbow verification, based on Eurofins batch analyses
What exactly am I buying?
Tonnes of CO₂ that have been taken out of the atmosphere by crops and stored as biochar carbon. The removals are certified under the Rainbow Standard at the 100-year permanence tier and recorded in its registry.
How long does the carbon stay stored?
Our removals are certified at the Rainbow Standard’s 100-year permanence tier, which requires a hydrogen-to-carbon ratio below 0.7; our 2024 and 2025 batches measured 0.186 and 0.195. The science points much further: peer-reviewed modelling gives inertinite-rich biochar a half-life of more than 100,000 years. We have not yet measured the inertinite content of our own biochar; that measurement is planned.
How is it verified?
Each production batch is analysed by Eurofins, an independent lab. The carbon removal is validated and verified by an independent verifier under the Rainbow Standard, where the project and its credits are listed publicly.
What does it cost?
The price depends on volume and delivery period. Send us what you need and we will reply with a proposal.
Can we buy for several years ahead?
Tell us which years you want to cover and we will tell you what we can deliver.
Where does the biochar go?
Into soil, mostly in Sweden: farmland and urban green spaces, football pitches and the ground beneath new buildings.
Is the biochar safe to put in soil?
Each production batch credited under the Rainbow Standard has been analysed by Eurofins for heavy metals and other contaminants and was within the Rainbow methodology’s limits. Ask us for the analyses.
