We track the progress of a carbon removal project through our certification framework. This roadmap moves from a preliminary assessment of eligibility toward full certification under the Puro Standard.
The facility has successfully completed the preliminary assessment conducted by the Puro team, meeting the minimum criteria for listing as a future supplier on Puro.earth.
The facility has passed the third-party facility audit, verifying compliance with the methodology, as well as output audit, verifying the net volume of removed carbon. The facility has been issued CORCs and continues its removal operations, as well as monitoring and reporting to Puro.earth.
Development status
We monitor a facility’s maturity as it moves toward industrial-scale operations. This status identifies whether a project is in development, under construction, or actively removing carbon from the atmosphere.
The feasibility study is ongoing. The Supplier is still collecting data to prove the concept.
The front-end engineering and design are ready and methodology compliant. There is a clear plan to monitor and measure. The LCA is up to the needed quality level or subject to small improvements. The technology has been used before. There are commercial agreements with the relevant business partners of the facility.
The facility is fully funded and is being implemented. Relevant infrastructure is being built.
The facility is operating as a carbon removal facility.

More about BioCirc Vinkel CCS K/S
BioCirc’s Bioenergy with Carbon Capture and Storage (BECCS) project is a large-scale initiative for permanent carbon dioxide removal from biomethane production. BioCirc owns and operates eight industrial-scale biogas plants across Denmark, producing around 1.7 TWh of biomethane annually. The biomethane is upgraded from biogas generated by anaerobic digestion of biogenic feedstocks such as agricultural residues, organic waste, and manure, all compliant with the sustainability and emission reduction criteria under the Danish implementation of EU Renewable Energy Directive.
In this project, five of BioCirc’s facilities - Vinkel, Vesthimmerland, Grønhøj, Favrskov, and Haderslev - will be retrofitted with carbon capture and liquefaction systems. Captured CO₂ will be transported via CO2 semi-trailers to an interim storage hub in the Port of Esbjerg. From there, it will be shipped for permanent geological storage in the Greensand Future Project - a Danish offshore CO₂ storage site in a depleted North Sea oil field at around 1,800 m depth. The project will capture and permanently store approximately 138,000 tonnes of biogenic CO₂ per year, corresponding to more than 800,000 tonnes of net carbon dioxide removals (CDR) between 2026 and 2032, after accounting for life-cycle emissions.
BioCirc’s BECCS project is among the first to combine biomethane production with permanent carbon storage under the Puro Standard. By integrating carbon capture into established biogas infrastructure, BioCirc provides a scalable and replicable model for negative emissions compatible with circular bioeconomy principles.
Through strong partnerships for equipment, storage and logistics, BioCirc ensures technical reliability and minimizes delivery risks. The project is supported by the Danish NECCS subsidy scheme. First CO₂ injection is planned for mid-2026, following completion of all permits and construction phases across the five capture sites.
1. BioCirc applies a circular approach to resource management. Feedstocks consist mainly of agricultural residues, manure, and organic waste. The digestate from biogas production is distributed to local farmers for use as organic fertilizer, supporting nutrient recycling and improved soil quality while reducing the need for synthetic fertilizers.
2. By connecting distributed biogas facilities to an offshore geological storage site, it helps build practical experience for green transition and decarbonization of the agriculture sector through CCS. The project is an important contributor to Project Greensand and forms part of Denmark’s emerging CCS infrastructure.
3. The project creates employment linked to the construction and operation of the capture plants, transport logistics, and storage activities. These opportunities contribute to economic activity and skills development in rural areas.
4. BioCirc engages with local communities through site visits, school partnerships, and support of local events and will now also display the use and benefits of carbon capture technologies.
