Cement additives supporting carbon neutrality
Cement producers are reducing the clinker content in cement as one way of achieving their goals of carbon-neutral cement production. The use of chemical additives to the cement can support these efforts. By Paolo Forni and Emanuele Gotti, MAPEI Spa, Italy. Grinding additives can lower the dosage of the concrete admixture significantly, while maintaining slump (© MAPEI Spa) To ach...
Compressed air as a resource
Compressed air is a valuable resource in any industrial plant. It is critical for the proper operation of the plants and in some cases can be linked to either the success or failure of specific equipment in the plant...
ML/AI-based maintenance to enhance energy efficiency
Recently, CemAI representatives were invited to present to the United States Environmental Protection Agency’s (EPA) ENERGY STAR® division on the topic of machine learning/artificial intelligence’s (ML/AI) use in inc...
Unlocking cement plant potential with digital twins
Cement manufacturers operate in an increasingly complex environment, facing pressure to maximise production while minimising costs and environmental impact. However, leveraging data to optimise operations can be hind...
Net zero shipping strategies
As the maritime sector looks to reduce its greenhouse gas emissions, fostering collaboration between cement producers and cement carrier operators can be of benefit to both industries. Decarbonisation options for bot...
Grinding for green goals
As a key decarbonisation path, the research and application of low-carbon cement grinding technology and equipment can help reduce power consumption and improve clinker quality. Research by Sinoma International Engin...
Maintaining quality with emission limits
The trend towards more sustainable cement production and decarbonisation has resulted in increased emissions control. While this has led to challenges in terms of maintaining quality, solutions are continually being ...
Cost savings on the road to net-zero
The road to net-zero is long and cost intensive, particularly on the process side of the building materials industry. However, a quick win on this journey is often neglected: logistics and transport. In this article ...
3D printing concrete: motivations, status and outlook
While automating concrete construction is not a novel idea, its more recent adoption has been driven by a need for productivity and sustainability. But what is its future? By Timothy Wangler, ETH Zürich Institute for...
SNCR: when the equation no longer holds
There are plants where selective non-catalytic reduction (SNCR) does not achieve the expected DeNO X results for no apparent reason. Often a look at the chemical processes in the background provides a clue as to why...
CO2NTESSA’s net-zero vision
The CO 2 NTESSA project will implement an innovative carbon capture (CC) technology at NEXE’s cement plant in Našice, Croatia. The existing plant will be modified based on the polysius® pure oxyfuel process, enabling...
Business models for utilisation of non-recyclable plastics in the Indian cement industry
Co-processing of plastic and other municipal solid wastes provides a safe and cost-effective way of dealing with waste in India and supports the country’s drive to adopt a circular economy approach. By Dr Gaurav Bha...
Carbon capture optimisation: add heat, reduce risk
While a range of carbon capture (CC) technologies are available to the cement industry, not all are a suitable option in terms of cost and risk. Ramboll looks at the benefits of an integrated amine-based solution. By...
Heidelberg Materials’ journey to net-zero
Heidelberg Materials is investing in multiple projects to achieve its ambitious target of reducing its CO 2 emissions by 47 per cent by 2030. From its first carbon capture and storage (CCUS) project at the Brevik pl...
Ironing out the carbon emissions of clinker production
The use of iron-rich industrial wastes can provide one of the pathways to decarbonising the global cement industry with high-ferrite cement types embodying less CO 2 than their ordinary counterparts. By Cecilia Pesc...
Towards Germany’s first fully-decarbonised cement plant
Heidelberg Materials’ new GeZero project will completely decarbonise cement production at the Geseke plant in North Rhine-Westphalia, Germany. The first of its kind project will establish a full carbon capture and st...
