Eco-aggregates: A new product for capturing CO2
Thanks to the technology and innovation by O.C.O Technology Limited, a company specializing in carbon capture, sustainable construction products, and waste treatment, we can capture and use the CO2 generated in our industrial processes to produce an eco-aggregate that the construction industry uses as a raw material in its manufacturing processes.
This eco-aggregate, which is produced using the ashes from the incineration of municipal solid waste (MSW) along with captured CO2, generates an important environmental benefit for society in addition to promoting the circular economy and industrial symbiosis with the construction sector.
What is the CO2 mineralization project?
At Repsol, together with our partner O.C.O Technology Limited, we’re going to start building a plant in the vicinity of our Petronor facilities to incorporate O.C.O technology for the manufacture of aggregates (gravel) produced from CO2 captured at the Petronor refinery and ashes. Aggregates are the raw material used by the construction industry to manufacture concrete and roads, among other uses.
These eco-aggregates promote the reuse of waste such as ashes by converting them into new raw materials that we reintroduce back into production cycles. The use of eco-aggregates will help reduce the consumption of natural aggregates.

Petronor incorporates a new plant for producing negative carbon aggregates into its processes
The new plant will start up in mid-2024, and it will use the technology developed by our partner O.C.O Technology Limited to reintroduce captured CO2 into the refinery along with other types of waste to subsequently be used as raw material.
With this plant, we continue to make progress towards our Company's goal of reaching net zero emissions by 2050 through the capture of CO2, one of the levers defined for this purpose.
Project selected by the EU Innovation Fund 2020
The European Commission's Innovation Fund provides funding to the most innovative projects aimed at developing low-carbon technologies that are in a phase close to a pre-commercial scale. The Commission will only fund 32 projects out of the 230 that were submitted to the European office in 2020. The construction of this plant is one of the projects chosen to receive a €3.2 million grant.
This project has been funded by the European Commission's EU Innovation Fund 2020. Project 101038931 – AGGREGACO2.
