Austria: Zementwerk Hatschek's Gmunden cement plant eliminated 3800t of CO₂ emissions from its local area during 2022 through its contribution to municipal heating. Zementwerk Hatschek, a subsidiary of Rohrdorfer, heats local households using recovered heat from the Gmunden cement plant's waste heat recover (WHR) system.

A delegation of cement plant representatives and local officials from Baden-Württemberg, Germany, visited the plant to learn about its WHR and heat supply systems on 20 January 2022.

Plant manager Peter Fürhapter said "Municipal heating based on our waste heat contributes to CO₂ reduction in Upper Austria, helping us to achieve our CO₂ reduction goals under the Paris Climate Agreement." He added "We are pleased that with this forward-looking project we are a model for similar projects in Europe."

Germany: Rohrdorfer and Austria-based Andritz Group are in the process of installing a 2t/day CO₂ separation plant on the roof of the former’s Rohrdorf cement plant in Bavaria. The pilot plant will capture CO₂ from the plant’s emissions for use by the regional chemicals industry. The Ingenieur newspaper has reported that it will cost Euro3m and is scheduled for commissioning before June 2022. It is the first installation of its kind at a German cement plant.

Rohrdorfer’s plant and process engineering manager Helmut Leibinger said “We must begin to see CO₂ as a product of value rather than a problem. With CO₂ as a carbon source, Germany can protect the climate and at the same time become less dependent on oil and natural gas. In addition, value creation and jobs will remain in the country.”

Austria: Rohrdorfer Group has awarded an engineering, procurement and construction (EPC) contract to Humboldt Wedag, a subsidiary of KHD, for the modernisation of the kiln line at its cement plant operations in Gmunden. The upgrade will enable the flexible usage of a wide range of waste fractionally pre-treated derived fuels on a high substitution rate.

The modernisation project comprises the design and supply of KHD’s world´s first ever Pyrorotor Calciner Technology, as well as the replacement of the existing satellite cooler with a new generation Pyrofloor PFC2 clinker cooler. The existing three station rotary kiln will be fitted with a new kiln drive and a new kiln hood as well as kiln inlet and outlet.

With the installation of the new Pyrorotor Calciner Technology from KHD the Gmunden plant will be able to burn very coarse waste derived fuels including whole rubber tires, which will lead to drastically reduced requirements in regard to waste pre-treatment. Therefore, the kiln modification will also emphasise on pollutant emission reduction.

The contract includes: three new preheater cyclones; a new preheater ID-fan; a tertiary air duct; a Pyrotop compact calciner mixing chamber; Pyrorotor Calciner burning chamber technology, a Pyroclon Calciner Burning System; a new kiln bypass unit; a multi-fuel Pyro-Jet kiln burner for primary and secondary fuels; a new kiln drive and kiln hood; a Pyrofloor PFC2 clinker cooler equipped with a Pyrocrusher roller type clinker crusher; and Simulex plant simulation software.

KHD services include the dismantling of existing equipment parts as well as the engineering, design, supply and erection of new equipment including commissioning services. Commissioning of the new system is scheduled for April 2019.

Europe: Cemex has completed the sale of its business operations in Austria and Hungary to Germany's Rohrdorfer Group for about Euro160m.

Cemex's Austrian operations, which comprise 24 aggregate quarries and 34 ready-mix plants, reported Euro219m in net sales in 2014. The operations in Hungary include five aggregate quarries and 34 ready-mix facilities and had net sales of some Euro42.7m in 2014.

Cemex hired Bank of America Merrill Lynch, Citigroup, BNP Paribas and Morgan Stanley & Co International plc to act as financial advisors in this transaction. The proceeds from the sale will be used mainly to finance general corporate purposes and to pay off debt.

Europe: Cemex has signed an agreement for the sale of its operations in Austria, Hungary, Croatia, Bosnia and Herzegovina, Montenegro and Serbia.

Its assets in Croatia, Bosnia and Herzegovina, Montenegro and Serbia will be sold to Duna-Dráva Cement (HeidelbergCement) for approximately Euro231m. The assets mainly consist of three cement plants (approximately 1.66Mt of cement sold in 2014), two aggregate quarries (approximately 0.16Mt of aggregates sold in 2014) and seven ready-mix plants (approximately 0.25Mm³ of ready mix sold in 2014). Cemex's operations in Croatia, including Bosnia and Herzegovina, Montenegro and Serbia had net sales of approximately Euro124m in 2014.

Its assets in Austria and Hungary will be sold to Rohrdorfer Group for approximately Euro160m. The Austrian operations consist of 24 aggregate quarries (approximately 6.47Mt of aggregates sold in 2014) and 34 ready-mix plants (approximately 1.60Mm³ of ready-mix sold in 2014). Cemex's operations in Austria had net sales of approximately Euro217m in 2014. The Hungarian operations being divested consist of five aggregate quarries (approximately 1.36Mt of aggregates sold in 2014) and 34 ready-mix plants (approximately 0.46Mm³ of ready-mix sold in 2014). Cemex's operations in Hungary had net sales of approximately Euro42.2m in 2014.

The proceeds obtained from the transactions will be used mainly for debt reduction and for general corporate purposes. The closing of the transactions is subject to the satisfaction of standard conditions for this type of transaction, which includes authorisation by regulators.
