thyssenkrupp develops technology for carbon capture

The production of cement releases large quantities of carbon dioxide (CO2). Only a third of these CO2 emissions result from the combustion of fossil fuels such as coal or petroleum coke, while the biggest share is released by the calcination of limestone. Depending on quality, limestone ??the main component of cement ??consists of 35% to 44% CO2.

Luc Rudowski, Head of Innovation at thyssenkrupp Industrial Solutions, Business Unit Cement Technologies: ??educing CO2 emissions in cement production is one of the most important challenges facing the industry today. As part of our #grey2green journey we are developing technologies and solutions for sustainable cement production without losing sight of plant profitability and productivity. One example of this is the newly developed polysius? pure oxyfuel technology for optimum CO2 separation. Other solutions developed from more sustainable cement production using polysius? activated clay or polysius? booster mill, the optimal use of alternative fuels with prepol? SC, to reducing NOx emissions through Cemcat? SCR.??/p>

Oxyfuel ??pure oxygen replaces air in the kiln

The Oxyfuel technology replaces ambient air in the clinker production process with pure oxygen introduced into the front zone of the cooler. As the nitrogen content of the air is no longer present, the CO2 concentration in the kiln exhaust gas can be increased to up to 100%. This much more efficient CO2 separation serves as the basis for the downstream utilisation or storage of carbon dioxide.

However, the advantage of reducing the exhaust gas to a virtually pure CO2 stream means that there is too little gas in the preheater to operate the cyclones. In the first-generation. Dr. Georg Locher, Head of R&D: ??ith the second-generation polysius? pure oxyfuel process, exhaust gas recirculation can be eliminated, resulting in considerable savings in investment and operating costs, and making polysius? pure oxyfuel the best-in-class technology for CO2 capture. Another advantage is that existing kiln plants can also be retrofitted with this process. By using the polysius? pure oxyfuel process, our customers profit from optimised operating costs, while freeing our communities and environment from high CO2 emissions.??/p>

Research company CI4C investigating use of polysius? pure oxyfuel

The four European cement manufacturers Buzzi Unicem-Dyckerhoff, HeidelbergCement AG, SCHWENK Zement KG, and Vicat plan to investigate the industrial-scale use of Oxyfuel carbon capture technology in cement production in a demonstration plant. To this end, the research company ??I4C – Cement Innovation for Climate??was established. The aim is to capture 100% of the CO2 and use it with the help of renewable energies to produce so-called ??efuels?? i.e. climate-neutral synthetic fuels such as kerosene for the aviation industry.

Dr. Markus Sauer, Senior Proposal Manager: ??he research company CI4C and thyssenkrupp are currently investigating the use of our polysius? pure oxyfuel technology in a demonstration plant. Working with our long-standing customers, we would be delighted if we could demonstrate the efficiency of our technology for the first time on an industrial scale.

Molecor Renews OCS Europe Certification Across Spanish Plants

Certification reinforces commitment to preventing microplastic pollution

Published

Molecor has renewed its OCS Europe certification for another year across all its production facilities in Spain under the Operation Clean Sweep (OCS) voluntary initiative, reaffirming its commitment to sustainability and environmental protection. The renewal underlines the company’s continued focus on preventing the unintentional release of plastic particles during manufacturing, with particular attention to safeguarding marine ecosystems from microplastic pollution.

All Molecor plants in Spain have been compliant with OCS Europe standards for several years, implementing best practices designed to avoid pellet loss and the release of plastic particles during the production of PVC pipes and fittings. The OCS-based management system enables the company to maintain strict operational controls while aligning with evolving regulatory expectations on microplastic prevention.

The renewed certification also positions Molecor ahead of newly published European regulations. The company’s practices are aligned with Regulation (EU) 2025/2365, recently adopted by the European Parliament, which sets out requirements to prevent pellet loss and reduce microplastic pollution across industrial operations.

Extending its sustainability commitment beyond its own operations, Molecor is actively engaging its wider value chain by informing suppliers and customers of its participation in the OCS programme and encouraging responsible microplastic management practices. Through these efforts, the company contributes directly to the United Nations Sustainable Development Goals, particularly SDG 14 ‘Life below water’, reinforcing its role as a responsible industrial manufacturer committed to environmental stewardship and long-term sustainability.

Coforge Limited has recently announced the launch of Coforge Data Cosmos, an AI-enabled, cloud-native data engineering and advanced analytics platform aimed at helping enterprises convert fragmented data environments into intelligent, high-performance data ecosystems. The platform strengthens Coforge’s technology stack by introducing a foundational innovation layer that supports cloud-native, domain-specific solutions built on reusable blueprints, proprietary IP, accelerators, agentic components and industry-aligned capabilities.

Data Cosmos is designed to address persistent enterprise challenges such as data fragmentation, legacy modernisation, high operational costs, limited self-service analytics, lack of unified governance and the complexity of GenAI adoption. The platform is structured around five technology portfolios—Supernova, Nebula, Hypernova, Pulsar and Quasar—covering the full data transformation lifecycle, from legacy-to-cloud migration and governance to cloud-native data platforms, autonomous DataOps and scaled GenAI orchestration.

To accelerate speed-to-value, Coforge has introduced the Data Cosmos Toolkit, comprising over 55 IPs and accelerators and 38 AI agents powered by the Data Cosmos Engine. The platform also enables Galaxy solutions, which combine industry-specific data models with the core technology stack to deliver tailored solutions across sectors including BFS, insurance, travel, transportation and hospitality, healthcare, public sector and retail.

“With Data Cosmos, we are setting a new benchmark for how enterprises convert data complexity into competitive advantage,” said Deepak Manjarekar, Global Head – Data HBU, Coforge. “Our objective is to provide clients with a fast, adaptive and AI-ready data foundation from day one.”

Supported by a strong ecosystem of cloud and technology partners, Data Cosmos operates across multi-cloud and hybrid environments and is already being deployed in large-scale transformation programmes for global clients.

India, Sweden Launch Seven Low-Carbon Steel, Cement Projects

Joint studies to cut industrial emissions under LeadIT

India and Sweden have announced seven joint projects aimed at reducing carbon emissions in the steel and cement sectors, with funding support from India’s Department of Science and Technology and the Swedish Energy Agency.

The initiatives, launched under the LeadIT Industry Transition Partnership, bring together major Indian companies including Tata Steel, JK Cement, Ambuja Cements, Jindal Steel and Power, and Prism Johnson, alongside Swedish technology firms such as Cemvision, Kanthal and Swerim. Leading Indian academic institutions, including IIT Bombay, IIT-ISM Dhanbad, IIT Bhubaneswar and IIT Hyderabad, are also participating.

The projects will undertake pre-pilot feasibility studies on a range of low-carbon technologies. These include the use of hydrogen in steel rotary kilns, recycling steel slag for green cement production, and applying artificial intelligence to optimise concrete mix designs. Other studies will explore converting blast furnace carbon dioxide into carbon monoxide for reuse and assessing electric heating solutions for steelmaking.

India’s steel sector currently accounts for about 10–12 per cent of the country’s carbon emissions, while cement contributes nearly 6 per cent. Globally, heavy industry is responsible for roughly one-quarter of greenhouse gas emissions and consumes around one-third of total energy.

The collaboration aims to develop scalable, low-carbon industrial technologies that can support India’s net-zero emissions target by 2070. As part of the programme, Tata Steel and Cemvision will examine methods to convert steel slag into construction materials, creating a circular value chain for industrial byproducts.
