Each ton of CO2 which can be prevented reduces cost and impact on the environment. Overall, installation of energy- and emission-saving refractories additionally results in cost savings, which must not be bypassed to meet the carbon challenge.
Together with a direct reduction plant, thyssenkrupp Steel Europe builds two smelters at its Duisburg/Germany site. Tests in pilot-scale demonstrate that water quenched smelter slag is glassy and has a significant own latent hydraulic reactivity. Therefore, it is a promising new supplementary cementitious material.
With the project for utilizing waste heat from the clinker cooler exhaust at the Allmendingen site, SCHWENK demonstrates how innovative energy optimization can enable triple use of waste heat.
With its “Circular Packaging” concept, Austrian-based Starlinger & Co GmbH provides a circular and ecologically conscious system for flexible plastic packaging such as FIBCs and sacks made of woven polypropylene tapes.
The feeding of alternative fuels (AFs) is a challenging task, due to its inherent volatile material properties. Especially the vertical transport of AF particles in classical bucket elevators can lead to enormous throughput variations and associated conveying problems. This article presents an automatic optimization methodology for bucket elevators based on artificial intelligence and reinforcement learning.
From 23 – 25 July 2025, the 6th International Conference on Polycarboxylate Superplasticizers (PCE 2025) was held at Century Park Hotel in Bangkok/Thailand. The conference provided valuable insights into the basics of PCE molecular design, high-performance applications and the key role of PCEs in the ongoing “green” transition of the cement industry to low-carbon binders, especially those formulated with diverse supplementary cementitous materials (SCMs).
The oleochemical industry is rooted in renewable raw materials such as natural oils and fats, making it one of the oldest contributors to the European bioeconomy. By offering products that are both high-performing and bio-based, oleochemicals support the global transition to a sustainable and circular economy. In line with this, we are committed to developing environmentally friendly, long-lasting solutions tailored to the needs of multiple industries – including the construction sector.
The processing of copper scrap involves many precisely coordinated processes. This is the only way to ensure that the recycled copper can be used effectively later on. When it comes to level instrumentation, Montanwerke Brixlegg relies on radar technology from Vega.
Maximum landfill diversion should not be seen as a challenge in waste management but rather as a chance for a more sustainable clinker production. Only the biogenic organic components in RDF do not contribute to global warming. With the Eggersmann FUEL process not only the recyclables in MSW are converted to RDF but also the organic fraction will be an important part of high-quality alternative fuel.
The lime industry is under pressure to decarbonize like hardly any other sector. Fossil fuels drive emissions and costs upwards – and call for bold alternatives. At Albert Knoblinger GmbH & Co. KG we have taken on this challenge and, together with Köhler Kalk in Germany, implemented a pioneering plant that is making history: For the first time in Germany, lime is being produced using 100% biogenic fuel.
