Achieving climate neutrality in the cement and lime industries poses a particular challenge, given that the majority of CO₂ emissions are caused by raw material-related emissions from the decompo-sition of limestone. The capture and storage of CO₂ (carbon capture and storage, CCS) is therefore pivotal in enabling these industries to achieve climate neutrality. The selection of a suitable capture technology is contingent on site and plant-specific conditions. In many cases, multiple production lines or products exist which generate substantial CO₂ emissions.

The working plan of the Research Institute of the Cement Industry was aimed at systematic investigation of the mix formulation and workability of a nano-based cement-bound adhesive.

In the IGF (Cooperative Industrial Research) project the framework conditions for a possible performance test method for evaluating the alkali reactivity of concrete was calibrated on the basis of the requirements of the German regulations.

The aim of this research project was the laboratory and industrial production and testing of cements that contain levels of limestone above the maximum content described in DIN EN 197-1.

With us, you can expand your knowledge around the production of cement and lime, as well as in the area of concrete technology. As a competent partner, we have been offering our customers individual qualification solutions since 2010. In addition to German-language online courses, we also offer English- and Russian-language courses and other services.

In this training you will become familiar with all relevant aspects concerning the use of alternative fuels in cement plants. Starting with the main political drivers such as the circular economy and the European waste fuel strategy, you will get a detailed insight into the current state-of-the-art-situation with regard to the use of alternative fuels in the EU. In this context, pre-treatment and suitable quality control of alternative fuels will be also explained and presented to you. You will focus on all the relevant aspects of the use of alternative fuels in the burning process (e.g. drivers and barriers of their use, available process technology and latest developments) and discuss them in the sessions. You will acquire knowledge about technical feasibility and optimisation potential, and have the possibility to discuss case studies.

VDZ’s online seminar “Strategies for the decarbonisation of the cement industry” aims to train technical staff that will be involved in the development and implementation of decarbonisation strategies in the cement industry in the coming decades. As a participant, you will gain a broader perspective on the challenges, opportunities, uncertainties and technical solutions available to achieve the ambitious goal of net zero CO₂ emissions in the future. Starting with energy efficiency and utilisation of alternative fuels, you will learn about state-of-the-art technologies, technical limitations, identification of improvement potential and industrial case studies. You will also get an insight into the current regulatory framework and how the implementation of CBAM might influence investment strategies in cement plants in Europe and beyond over the next decade. You will look ahead and discuss innovative CO₂ reduction possibilities, such as calcined clays, use of artificial intelligence (AI) and CCUS. Calcined clays will be presented from a technology and materials perspective. You will also learn about different CC technologies and their operating principles, TRL evolution prospects and associated technological risks, selection criteria and critical techno-economic requirements. At the end of the online seminar, you will understand the fundamentals of machine learning and how AI can be used for process parameter prediction in the present, as well as for the development of autonomous systems for process control in carbon capture cement plants in the future.

The 9ᵗʰ International VDZ Congress took place in Düsseldorf on 6 – 8 November 2024. The VDZ Congress is the international scientific forum for the cement industry and its suppliers. Delegates from all over the world discuss the latest developments concerning the transformation of the industry on its way towards climate neutrality.
