The KOdeCO net zero project aims to make Holcim’s Koromačno plant the first to produce net-zero cement in Croatia and the Mediterranean. It will establish a first-of-its-kind, end-to-end carbon capture and storage value chain between the plant and storage under the Mediterranean. 

Adopting a highly scalable low-risk solution, the project uses renewable electricity which enables 20% electricity savings, higher efficiency, circularity of condensate and reduced water consumption. 

With a vision for the Koromačno plant to be net-zero by 2028, the project aims to capture and store around 366,000 tons of CO2 per year. The project’s decarbonization efforts led to it being selected for an EU Innovation Fund grant in 2023 as well as the Just Transition Fund.

The technology behind the project

The project will capture CO2 through absorption end-of-pipe technology. It will use Air Liquide’s Cryocap™ FG non-intrusive carbon capture and liquefaction technology, which is adapted to the direct capture of clinker production flue gas. 

The Koromačno plant will provide intermediate storage to prepare liquefied CO2 to be loaded onto vessels and then permanently stored under the Mediterranean. 

The project will also integrate first-of-their-kind water treatment and desalination plants to further decrease Koromačno’s environmental footprint with the aim of becoming a zero fresh water usage site.

The advantage of the project is that we’re located at sea, so it reduces the logistic aspects and enables us to use seawater as a cooling medium for the cement manufacturing process.

More on Holcim's net-zero journey

Go4ECOPlanet will install a unique facility to capture 100% of CO₂ emissions generated during the production of clinker – the key ingredient in cement production.

In Belgium, the GO4ZERO project will deploy an innovative carbon capture technology at our plant in Obourg, and transport CO2 for offshore storage under the North Sea.

eCapt-Rhône: Creating the first CO2 capture facility at a white cement plant

The eCapt-Rhône project uses renewable hydrogen production and CO2 captured from Holcim’s cement plant in Le Teil to generate e-methanol. 

OLYMPUS is a flagship project in Holcim’s European decarbonization roadmap. It will lead to the development of storage capacity in southern Europe.

The Carbon2Business project at our cement plant in Lägerdorf, Germany aims to capture more than 1.2 million tons of CO2 emissions annually.
