Germany: Austria-based Rohrdorfer has started up an amine-based carbon capture system at its Rohrdorf cement plant in Bavaria. The producer plans to ultimately expand the system up to a capture capacity of 1500t/day. The inauguration follows a successful continuous trial of the technology since August 2022, excluding a regular kiln maintenance period over winter. Austria-based Andritz designed the system specifically for the Rohrdorf cement plant. It yields CO2 that is suitable for numerous applications, including in food and beverages and in intermediate products in pharmaceuticals production. The Rohrdorf cement plant also hosts a formic acid plant which uses captured CO2.
Rohrdorfer aims to achieve carbon-neutral cement production by 2038. Alongside production-related optimisations, the producer plans to realise its aim through a future expansion to the Rohrdorfer plant’s carbon capture system and the implementation of a further carbon capture upgrade at a second cement plant in Austria.
