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.

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.

Cements of the Future 2025
With the decarbonisation of cement production and the expected reduction in blastfurnace slag and fly ash quantities, unburned limestone, calcined clays, and recycled fines will gain in importance as cement main constituents. The focus will be on new, clinker-effcient cement types such as CEM II/C and CEM VI cements, whose performance allows a wide range of applications in practice. This online seminar provides an overview of the current state of development and standardisation of new cements. The possibilities and limits for practical implementation will be presented.

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.

Durability of concretes with clinker-efficient cements CEM II/C and CEM VI
EN 197-5 defined the clinker-efficient cements CEM II/C and CEM VI. Technical approvals for the application of CEM II/C cements have been issued. For a wide application, all parties involved have to develop confidence in the new products. With new findings on fresh concrete properties, hardening behaviour and durability two research projects of the VDZ Concrete Technology Department will provide an important basis for the application of these cements in the construction industry.
