Carbon negative aggregates specialist O.C.O Technology (O.C.O) and Repsol-Petronor have joined forces to develop Europe’s first commercial plant to develop carbon negative aggregates.
The project will use O.C.O’s patented Accelerated Carbonation Technology (ACT) process that will allow for the treatment of various types of raw material with waste carbon dioxide (CO2) from Repsol-Petronor’s refineries.
This treatment process will produce a carbon negative artificial aggregate - Manufactured LimeStone (M-LS) - that has permanently captured CO2 and will be used in the construction sector.
O.C.O claims that the technology behind the process will allow for the treatment of around 22,000 tonnes of waste every year, cutting an estimated 2,200 tonnes of carbon emissions annually.
Speaking about the agreement, Stephen Roscoe, Technical Director, O.C.O Technology, said, “Developing this European facility in partnership with Repsol-Petronor is a significant development for O.C.O and one we are very excited about.”
“Partnerships of this calibre demonstrate O.C.O’s strength as a market leader in carbon capture technology and show the huge potential that our ACT process has within different industry sectors.”
Funded by the European Commission’s Innovation Fund, the project was one of only 32 successful funding applicants out of 230 submissions, underlining the company’s credentials on the European carbon reduction stage.
O.C.O is also working with Mitsubishi Corporation (Mitsubishi) to assess the opportunity for carbonating new waste materials, in particular a project which will utilise ACT for the carbonation of slag waste from steel processing plants.
The Japanese manufacturing giant chose O.C.O as one of only four global companies – and the only one in the UK – to join its Green Concrete Consortium, a group of organisations dedicated to the design and creation of turning CO2 into carbon negative concrete and aggregates.
Expected to be completed by mid-2024, the project will see its new facility built near Petronor in Spain.
