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.
Cement production has always been a complex balancing act of meeting process targets, but the level of variability in today’s plants is unprecedented. Alternative fuels vary in calorific value and moisture content from one delivery to the next. Supplementary cementitious materials (SCMs) shift raw mix chemistry in ways that are difficult to predict. All of this must still be managed while keeping clinker quality consistent and equipment running smoothly. The real Green Challenge isn’t simply reducing emissions - it’s mastering the growing operational complexity without losing efficiency or profitability.
As a partner in the “WAGEOS2SHS” (Wassergranulation von Elektroofenschlacke zu Schwarzem Hüttensand; water granulation of electric furnace slag to black granulated blast furnace slag) research project, Holcim is testing another promising approach to decarbonizing the construction industry and cross-sector circular economy.
Calectra’s power-to-heat thermal storage technology can significantly reduce process heating OPEX (33% in Germany in 2024) and combustion-related emissions (up to 100% depending on power source) for cement and lime manufacturers. It is leveraging the growing trend of low-cost, off-peak electricity availability resulting from the surge of renewables.
It is well known that the building materials industry is one of the largest emitters of greenhouse gases worldwide. While cement manufacturers can primarily reduce their process-related emissions, sand-lime brick producers can already achieve savings in raw material processing. Advanced mixing technology makes this possible.
This article presents an optimal rotary kiln for calcined clay that decouples drying and calcination. This two-stage approach reduces heat consumption, lowers footprint, minimizes off-gas treatment and enhances operational control compared to traditional single kilns, making rotary kilns an even more competitive alternative to flash calciners.
The European paper sack and sack kraft paper industry has embarked on a journey to develop a pathway towards net zero. The current focus is on identifying the main contributors to the industry’s carbon footprint and key areas for decarbonisation.
Drywall constructions are excellently suited for the purpose of structural fire protection. Structures ranging from non-load-bearing internal partition walls to suspended ceilings and shaft walls have been certified for their fire resistance capability, either by inclusion in DIN 4102-4 or through manufacturer-specific certificates such as abP, abG or ETA.
