TAIL-END TECHNOLOGIES

As part of our ambitious decarbonisation strategy, we are focusing not only on integrated oxyfuel technology but also on tail-end technologies for CO₂ capture. These have the advantage that they can be flexibly connected to existing plants and thus integrated into existing facilities. Our site in Brocēni, Latvia, serves as a central test base for this purpose.

CapsolGo®

The container-based CapsolGo® pilot plant uses the hot potassium carbonate (HPC) process for CO₂ capture. It was successfully commissioned in early 2025, initially at the Akmenės Cementas plant in Lithuania. After completion of the first test phase, the plant was relocated to Brocēni in May 2025, where it has been in operation ever since. A key element of the ongoing test phase in Brocēni is the newly developed hot gas cleaning plant. It treats the flue gas in a targeted manner by removing dust particles prior to CO₂ capture – with the aim of also reducing sulphur and nitrogen oxides in the future. The test phase will run until the end of 2025. During this period, comprehensive operating data will be collected, including water consumption, CO₂ concentrations, temperature profiles and the efficiency of exhaust gas cleaning. These findings will form an important basis for the further development of our decarbonisation strategy.

Svante

In addition to the CapsolGo® campaign, the CO₂ capture technology developed by Canadian company Svante has also been undergoing testing in Brocēni since August 2025. This technology uses metal-organic frameworks (MOFs), which absorb CO₂ molecules like a large sponge. The physical process is characterised by high energy efficiency and ease of use. The technology has already proven itself in the oil and gas industry and is now also being tested under real conditions in a cement plant.
