VDZ represented at the 16th International Congress on the Chemistry of Cement (ICCC) 2023 in Bangkok
The 16th International Congress on the Chemistry of Cement (ICCC) 2023 in Bangkok is in full swing. Dr Martin Schneider was pleased to give a keynote speech on the cement plant of tomorrow which was met with great interest from the participants. Aiming at net-zero CO₂ emissions by 2050, the cement and concrete sector is going through its biggest transformation ever. Cement plants will have to implement all CO₂ abatement and saving measures – both conventional and breakthrough – to the best extent possible.

Shaft kiln for calcining raw meal for clinker production in the cement industry - an efficient technology for concentrating CO₂ in the waste gas
The capture of CO₂ and its subsequent use and storage are essential elements of the cement industry's decarbonisation strategy. The capture of CO₂ from the flue gas is energy-intensive and complex. It can be carried out more easily and efficiently by maximizing the CO₂ concentration in the flue gas. The separation of the calcination of the limestone in the raw meal from the burning process to produce clinker phases simplifies the accumulation of CO₂ in the flue gas significantly.

7 - 8 March 2023: Public Workshop on Carbon Capture for the Cement and Lime Industry hosted by AC²OCem and ANICA
The abatement of CO₂ emissions from industry processes is recognised as a key challenge for achieving carbon neutrality by 2050. During the past three years carbon capture options for the cement and lime industry have been further developed in the ACT- funded international research projects AC²OCem and ANICA. The consortia of AC²OCem and ANICA now invite all interested people to a public workshop on carbon capture technologies which is organised by VDZ on 7 - 8 March 2023.

Resources of the future for cement and concrete
Alongside climate and species protection, the preservation of natural resources is one of the major ecological challenges of our times. The production of cement and concrete is an area of particular relevance in this respect, accounting for roughly one fifth of the primary raw materials used in Germany. "We are well aware of the enormous demand arising from our industry and are prepared to take responsibility for an even more careful use of natural resources", explains Christian Knell, President of the German Cement Works Association (VDZ). The new VDZ study "Resources of the future for cement and concrete – Potential and action strategies" describes a possible 2050 scenario aimed at further reducing primary raw material utilisation.

Environmental data of the German cement industry 2021 published
The "Environmental data of the German cement industry 2021", which has just been published, provides an in-depth insight into the use of raw materials, energy input and the various emissions produced by German cement manufacturers. This encompasses not only the dust and dust bound constituents, but also the inorganic and organic exhaust gas compounds. A further aspect is information on carbon dioxide emissions, the reduction of which is a particular focal point in connection with the decarbonisation of cement production.

Less energy use through optimisation and new ways of comminution
60% of the electrical energy comsumed in cement production is used for comminution. In order to reduce this amount, VDZ is engaged in researching new ways of comminution and optimising existing grinding plants. You can find more information in the following video.

A process-integrated method for calcining clays
The use of calcined clays as a main component of cement or as an additive to concrete is becoming increasingly important and of interest from an economic and ecological point of view. Standards such as the European Cement Standard EN 197 already today provide for the use of calcined clays (as natural tempered pozzolan) as a main component of cement. Depending on their chemical and mineralogical composition, the clays used must in principal be heated to temperatures of over 600 °C in order to achieve their pozzolanic potential. VDZ has developed a new process for this purpose, which we are pleased to present to you in the attached document.
