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

In this research project, IR spectroscopy in combination with mathematical tools (chemometrics) is going to be evaluated as an analytical method for the characterisation of silica based materials, primarily X-ray amorphous materials, with regard to the reliable determination of the composition of material mixtures with X-ray amorphous materials (e.g. ternary cements with calcined clay and/or recycled concrete fines). In a next step, the findings on the analytical method and evaluation routines developed for cement are going to be evaluated with regard to their transferability to siliceous aggregates for estimating its alkali sensitivity.

REDOL - Aragon's REgional Hub for circularity: Demonstration Of Local industrial-urban symbiosis initiatives

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.

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.

Investigation and optimisation of the dynamic operating characteristics of the oxyfuel-operated cement clinker burning process for CO₂ capture

The oxyfuel technology is to be investigated qualitatively using a dynamic process simulation. This will provide a basis for the control and optimization of oxyfuel systems, resulting in a faster rollout of this crucial technology for CO₂ reduction.

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.

Automised Classification and Assessment of Alternative Fuels

The aim of the project is to investigate Machine Learning models for the characterisation of alternative fuels in the cement production. For this purpose, a public-accessible database (with fuel characteristics and images) is set-up and different machine learning models will be trained on that data, the algorithms will be tested on their robustness and suggestions for the classification of the fuel quality and its visualisation in the control room will be made.
