Request publicationIn 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.
In der Broschüre werden Empfehlungen zur Optimierung des Naturschutzmanagements in Abbaustätten zusammengefasst. Dabei wird zwischen Maßnahmen nach Abschluss der Rohstoffgewinnung und während der Betriebsphase unterschieden. Neben Renaturierungsverfahren gehen die Verfasser auf "Wanderbiotope" und die Zusammenarbeit mit Naturschützern ein. Die Broschüre ist ein Beitrag der deutschen Zementindustrie zur Aktion "biologischevielfalt.de".

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.
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.

The effects of two-stage mixing on the early hydration and microstructure development of clinker-efficient Portland composite and composite cements as well as on the strength development and durability of concrete were determined. The aim was to determine the extent to which the performance of these cements can be improved by two-stage mixing processes.

Request publicationThe ANICA project (Advanced Indirectly Heated Carbonate Looping Process) investigated the development of a novel, indirectly heated carbonate looping process to reduce energy consumption and costs for CO₂ capture from lime and cement plants.
Research report (in German) on IGF project 21582 N, in which process chains for chemical CO₂ utilisation for the emission reduction in the cement industry were to be investigated.
VDZ's Education and Training Programme 2024/25 ranges from teaching technical basics and technical expertise to further training for managers. We offer individual, tailor-made seminars on the topics of clinker and cement production, maintenance, quality assurance, environmental protection, and concrete technology. In this new brochure you will find two new seminar topics reflecting current developments in the cement and concrete industry.

The capture of CO₂ and its subsequent use and storage are essential elements of the cement industry's decarbonisation strategy. The capture of CO₂ from the flue gas is energy-intensive and complex. It can be carried out more easily and efficiently by maximising the CO₂ concentration in the flue gas. The separation of the calcination of the limestone in the raw meal from the burning process to produce clinker phases simplifies the accumulation of CO₂ in the flue gas significantly.
