Request publicationIn the AiF project EVCAZ, the energetic and material utilisation of wastes containing carbon fibres is to be demonstrated on an industrial scale in a cement plant. The central tasks are the evaluation of the conversion success of the CF fibres, the recording of the resulting emissions and the consideration of influences on the process and the clinker quality. The findings obtained are summarised to assess health and environmental risks and to answer questions relevant to approval as a decision-making aid for cement plant operators.
The purpose of the research project is to gain the first systematic scientific findings on spalling behaviour in the event of fire and on thermo-mechanical and thermo-physical properties for concretes with the new clinker-efficient cement types and with recycled aggregates.
Redol deals with closing material cycles using the city of Zaragoza as an example. The research project focuses on solid urban waste, which is an abundant source to produce circular products. Five value chains for solid urban waste in the Aragon region will be redesigned in order to be able to produce circular products using an industrial-urban symbiosis approach.
Our training schemes introduce career starters to cement technology, taking their different engineering or scientific backgrounds into account. This course provides a one-week in-depth training session which covers all relevant aspects of the cement manufacturing process including chemistry, mineralogy and environmental aspects. Quality control and cement performance in mortar/concrete will also be addressed.
Clinker production is the most energy-intensive process step in cement manufacturing. It can represent up to 90 % of the total energy demand in a cement plant and is therefore a main focus not only with regard to cost optimisation and quality improvement of the final product, but also regarding emission control and the reduction of impacts on the environment. VDZ’s training will enable participants to obtain a deeper knowledge of the clinker production process and a better understanding of the impacts that daily decisions of plant personnel can make on the plant’s performance (quality, electrical energy use, fuel consumption and emissions).
This course covers all the 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, the training will give a detailed view of 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. A main focus will be given to the drivers and barriers of the use of alternative fuels within the burning process. Key issues will be explained and discussed with the participants. Finally, technical feasibilities, case studies and optimisation potential will be part of the training course.
The 9th International VDZ Congress will take 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 will come together to discuss the latest developments and challenges concerning the transformation of the cement industry on its way towards climate neutrality.
