Following our Green Challenge issue, issue 8/2025 is another issue of special significance to us: this will be the last time that ZKG is published by Bauverlag and with us as your editorial team. We would therefore like to take this opportunity to express our sincere thank.

Rotary kilns are essential for cement production – as is the case at the Duna-Dráva Cement plant in Vác, northern Hungary, which belongs to the Heidelberg Materials Group. After a roller bearing on the kiln failed, the existing gear ring was severely damaged and had to be replaced.

Pakistan’s cement industry recovered in FY 2025 from the downturn in the last three years. However, the industry is fragmented and divided into North and South. This market review will provide the latest production data, the main players in the market and their production shares.

With the foreseeable end of coal-fired power generation, a key raw material for calcium sulfate binders, flue gas desulfurization gypsum (FGD gypsum), will no longer be available. In order to avoid having to fill the resulting gap exclusively with natural gypsum, gypsum recycling will play a significantly greater role in the future.

Heidelberg Materials has started delivering evoZero, the world’s first near-zero carbon captured cement, to customers across Europe. Based on carbon capture and storage (CCS) at Heidelberg Materi als. Furthermore, evoZero supports the construction of the new Skøyen Station in Oslo/Norway and the German 3D-printing project DREIHAUS.

The ongoing battle against dust in bulk material handling is a continuous challenge. The location and number of belt cleaners required, based on production volume and application on a conveyor system, are closely tied to safety, emissions, and operating costs. A common design challenge is positioning belt cleaners in the optimal locations.

The whole world is talking about artificial intelligence and that it is the quantum leap for all industries. Also for the cement industry?
