Evolving the well-established

Available in English

The 9th International VDZ Congress is just around the corner: From 6 to 8 November 2024 - for the first time since the COVID-19 pandemic - the VDZ Congress will provide a forum for global exchange in the cement industry. The focus in 2024 will be on key topics in cement process technology and the decarbonisation of the entire cement and concrete value chain. In the following interview, Dr Martin Schneider, Chief Executive of VDZ, explains what the biggest challenges and bright spots in the industry are at the moment, what contribution VDZ‘s CO₂ Roadmap will make to climate neutrality in the industry, and what key topics participants can look forward to at the 9th International VDZ Congress.

Partial oxyfuel - Separate calcination of raw meal to concentrate CO₂ in the exhaust gas

Available in German and English

The capture of CO₂ and its subsequent use and storage are key elements of the cement industry's decarbonisation strategy. The separation of CO₂ from waste gas is an energy-intensive and complex process. This process can be made simpler and more efficient by achieving the highest possible CO₂ concentration in the flue gas. If the calcination of the raw meal is separated from the actual clinker burning process, this considerably facilitates the concentration of CO₂ in the flue gas and reduces the "contamination" of the CO₂ with (false) air.

Naturschutz und Zementindustrie - Projektteil 2: Literaturstudie

Available in German

In der Studie wird neben einschlägiger Fachliteratur auch unveröffentlichtes Material erstmals systematisch ausgewertet. Insgesamt wird auf rund 600 Literaturstellen Bezug genommen. Eine zusammenfassende naturschutzfachliche Bewertung zeigt, dass nicht nur ehemalige, sondern auch betriebene Abbaustätten zum Artenschutz beitragen. Das Vorkommen seltener bzw. gefährdeter Tier- und Pflanzenarten ist vor allem auf die Strukturvielfalt und die Refugialfunktion der Abbauareale zurückzuführen.

Naturschutz und Zementindustrie - Projektteil 1: Auswertung einer Umfrage

Available in German

Die Umfrage bezieht sich auf alle integrierten Zementwerke in Deutschland. Die Auswertung zeigt u. a., dass auf rund 54 % der ehemaligen Abbauflächen die Folgenutzung "Naturschutz" umgesetzt wird. Demgegenüber dominiert bei der Vornutzung der Ackerbau, d. h. eine intensive Form der Landwirtschaft. Neben weiteren Daten zum Verhältnis von Rohstoffgewinnung und Naturschutz enthält die Broschüre auch Angaben zu Abbaumengen, zum Flächenbedarf und zur räumlichen Verteilung der Abbaustätten.

Competitive electricity costs – prerequisite for the production of cement in Germany

Available in German and English

In Germany, the costs of supporting renewable energies are spread out by means of reallocation to the power consumer in accordance with the renewable energies act (EEG). Firms with high electricity consumption can be partly relieved of this if they fulfil the strict quantitative and qualitative requirements of the EEG‘s special equalisation scheme. The aim of the scheme is to protect companies that use a lot of power due to the nature of their processes from losing their competitiveness vis-à-vis competing locations in other countries inside and outside of Europe. Recently there has been much heated discussion on the amount and distribution of costs under the EEG. Alongside the promotion of renewable energies, the relief of power-intensive firms has been subject to criticism. The present study by EEFA-Forschungsinstitut GmbH & Co. KG, Münster empirically investigates the international competition situation of the German cement industry in this context. The focus of the analysis is on the intensity of power costs for cement manufacture, the exposure of cement companies to international competition – both inside and outside of Europe – and the significance of EEG relief for the preservation of cement production and employment in Germany. The latter is evaluated in view of the expected effects of a potential increase in power costs on the sector and the German economy as a whole.
