Request publication[Translate to English:] Durch das Forschungsvorhaben sollten die Grundlagen für einen Einsatz von Mühlen zur gezielten Feinstmahlung von Zementfraktionen und zementartigen Produkten geschaffen werden.
Forschungsbericht zum IGF-Projekt 20514N, in dem die technisch-wissenschaftlichen Grundlagen einer Minderung der Quecksilberfrachten im Abgasweg von Zementdrehrohrofenanlagen durch eine sorbensunterstützte Staubausschleusung sowie Möglichkeiten der Optimierung untersucht werden sollten.
The aim of the project was to define the sensitivities of and relationships between the various influencing factors in a form applicable to plants in general.
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.
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.

Request publicationThe aim of the AiF research project was to identify the causes of the sometimes greater scatter rates in the analysis results in the case of comparison trials for the long-term tank test.
Interactions between different structured or modified methyl hydroxyethyl celluloses and cements blended with limestone, blastfurnace slag or fly ash were determined.
The aim of the project was to investigate the suitability of the Ono method for evaluation of burning conditions even on clinker burnt with alternative fuels. Furthermore the focus of the project was the development of a methodology for correlations between microscopically and mineralogically analysed clinker properties and burning conditions.
The aim of the research project was to find out why some CEM I-SR and CEM III/B-SR cements do not meet the criteria for high sulfate resistance (SR) under all conditions of the SVA test method, the common accelerated test method in Germany; although these cements show high sulfate resistance in practice.

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.
VDZ's Education and Training Programme 2023/24 ranges from the teaching of technical basics to the imparting of special technical knowledge and education courses for managers. VDZ offers individual, tailor-made seminars on the topics of clinker and cement production, maintenance, quality assurance, environmental protection and concrete technology. Almost all seminars can also be designed and implemented as inhouse seminars according to individual customer requirements. In this new brochure you will also find two new seminar topics reflecting current developments in the cement and concrete industry.
In keeping with our time-honoured tradition, this year's edition of the "Environmental data of the German cement industry" again provides an in-depth insight into the use of raw materials, energy input and the various emissions produced by German cement manufacturers. This encompasses not only the dust and dust bound constituents, but also the inorganic and organic exhaust gas compounds. A further aspect of our environmental data is information on carbon dioxide emissions, the reduction of which is a particular focal point in connection with the decarbonisation of cement production.

The "Environmental data of the German cement industry 2020" prove that cement manufacturers are facing up to the environmental challenges of our time and informing the public about them in a transparent way. The focus is on the topics of climate neutrality by 2050, saving primary raw materials, and air pollution control.
