Background
The Rohordorf plant is the flagship cement manufacturing facility for Rohordorf group. The plant has a history of pursuing carbon-reduction technologies, starting with the use of secondary fuels dating back to 1996. In 2022, a 2 tonne per day CO2 separation pilot plant was installed on the roof of the plant to capture CO2 for use by the regional chemicals industry, which was followed, in 2023, by an amine-based carbon capture system with the goal of expanding the system up to a capture capacity of 1500 tonnes of CO2 per day. In 2024, the plant commissioned a pilot clay tempering unit with the goal of utilizing tempered clay in cement production, which was followed by 50t/day clay calcination unit installed later in the year. Owner, Rohrdorfer Zement, estimates that, through the use of calcined clay, a reduction to the plant’s CO2 emissions by 16 – 18%, or by 30% if it achieves carbon neutral clay tempering through the use of green hydrogen. Additionally in 2024, the plant installed a photovoltaic array consisting of 1000 modules, which covers around 2000 square meters and has a peak output of 400kW. These innovations fall in line with Rohrdorfer's company-wide goal to achieve carbon-neutral cement production by 2038.
