Within CERNET, wine fermentation is being explored as a valuable source of biogenic carbon dioxide. While this CO₂ is traditionally released into the atmosphere, the project aims to capture and upgrade it so it can become a resource for the production of new bio-based products and ingredients. Demonstrating this approach in a commercial winery environment is essential for assessing the technical feasibility, operational performance and future replication potential of the technology.

A Collaborative Technology Development

The system has been developed through the collaboration between two CERNET partners Bodega Matarromera and CARTIF. The system integrates several purification technologies designed to obtain high-purity biogenic CO₂ while also enabling the recovery of valuable aromatic compounds naturally released during wine fermentation. These recovered compounds could create additional valorisation opportunities within winery processes.

Testing Under Real Production Conditions

The upcoming operational phase will provide the project consortium with its first opportunity to evaluate the system under real production conditions. Data collected during the campaign will help optimise performance, assess scalability and generate knowledge for the future deployment of similar solutions in wineries and other bio-based industries across Europe.

Towards Circular Carbon Solutions in the Wine Industry

This milestone represents an important achievement for CERNET's Demonstrator 3 and highlights the project's broader ambition: transforming biogenic carbon emissions from industrial activities into valuable resources that support a more circular and sustainable bioeconomy.
