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.

German cement industry on course for a carbon-free future
In the face of global climate change it will be imperative to drastically reduce greenhouse gas emissions throughout the world over the next few decades. This also applies to the cement industry. "We are well aware of our responsibility, and the industry in Germany is willing to make its contribution towards achieving climate neutrality in the future", says Christian Knell, President of the German Cement Works Association (VDZ). The new VDZ study, "Decarbonising cement and concrete: A CO₂ roadmap for the German cement industry", shows possible ways of mastering this transformation by the year 2050.

Demand for cement at a high level, outlook cautious
Speaking about the development of the German cement market, Christian Knell, president of VDZ, says "It has rarely been so difficult to make a forecast as it is this year". Since March 2020 the coronavirus pandemic has created a great deal of uncertainty amongst most people and companies in this country. So far the cement manufacturers have had no grounds for complaint, not least because favourable weather conditions helped the cement market to get off to a good start in 2020. "Despite the lockdown coming into effect in March, the demand for cement was upheld by the continuation of work on construction sites – also thanks to the quick action taken by the government", says Christian Knell, looking back on the situation.

Carbon footprint remains a challenge for the cement industry
In the past year, German cement manufacturers have invested in a large number of measures to further reduce their carbon footprint. These include both renewed efforts to improve the energy efficiency of cement production enabled by new production facilities and an additional increase in the share of alternative fuels utilising biomass. This is shown by the "Environmental Data of the German Cement Industry 2018" which is published annually by the German cement manufacturers. "We have also made significant progress this year and further improved our CO₂ performance," says Christian Knell, President of VDZ. "However, it is also clear that we are increasingly reaching our limits in reducing CO₂ emissions with existing technology. We are therefore working on new, future-oriented technologies, above all on capturing CO₂, which will allow us to continue using it or, if necessary, to store it."
