Field Trip
Confirmed field trip to Holcim Mannersdorf plant on 16 May 2025
The site of the Mannersdorf plant was first established as an industrial facility in 1894. In 1968 the plant received its first dry line, kiln No. 8, a KHD four-stage preheater line with a capacity of around 0.8Mt/yr of cement. In 1984 the plant moved to a precalciner system. In 2017 the relatively small separate line calciner was replaced by a large inline calciner to boost alternative fuel usage.
The current preheater from 1984 is a Parallel Air Serial Combustion (PASEC) system. The preheater has five stages with two strings. The kiln’s rated capacity is 2730t/day, which is around 0.9Mt/yr of clinker or 1.4Mt/yr of cement. To boost the use of alternative fuels and to improve the thermal efficiency a large inline calciner (ILC) with separate tower in front of the existing tower was erected 2016 - 2017. The ILC has a gas residence time of more than 7s. The alternative fuel rate was boosted by this to above 90% on stable days, with 100% refuse-derived fuel (RDF) at the calciner.
Holcim has announced that a major new carbon capture and sequestration project will take place at the Mannersdorf plant, Carbon2Product Austria, or C2PAT.
The first aim of the planned CCS project is to capture and store CO2, while the ultimate aim of the Carbon2Product Austria project is to create a cross-sectorial value chain, which will use the captured CO2 as a resource. In combination with green hydrogen, the captured CO2 could be transformed into renewable hydrocarbons, or as a feedstock to manufacture value-added plastics. The annual CO2 capture is expected to be around 0.75Mt, and the plant could be operational by 2030.
