Systematic application of IR spectroscopy to strengthen the circular economy in the construction industry

In this research project, IR spectroscopy is to be evaluated in combination with mathematical tools (chemometrics) as an analytical method for the targeted characterisation of silicate, primarily X-ray amorphous materials and for the reliable determination of the composition of material mixtures with X-ray amorphous materials (e.g. ternary cements with calcined clay or recycling flour, among others). Then the findings on the methodology and evaluation routines developed for cement are to be evaluated with regard to their transferability to silicate aggregates for determining alkali sensitivity.

CaLby2030 – Calcium Looping to capture CO2 from industrial processes by 2030

In CaLby2030, the deployment of Calcium Looping technology (CaL) using Circulating Fluidised Bed reactors (CFB) in the cement industry will be investigated, aiming at efficient CO₂-Capture without compromising clinker production or product quality. A technology scale-up will be also evaluated in a German cement plant by exploring different retrofit possibilities. Besides the cement sector, the deployment of CFB-CaL technology in other relevant sectors will also be investigated.

Process engineering investigation of the energetic-material utilisation of wastes containing carbon fibres in cement plants - EVCAZ

In 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.

Firing Alternative Fuels 2025

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.

Development of a method to improve clinker cooling and to increase energy efficiency in cement rotary kilns by using infrared cameras

In the research project, infrared cameras are used to record the surface temperature of the clinker bed in the clinker cooler. Together with calculated enthalpy flows, this allows control room personnel to identify the operating condition of the cooler. This is used in operational tests to optimise the heat transfer in the clinker cooler by controlling the drive system and adjusting the cooling air distribution.
