Maintaining quality with emission limits19 December 2023, Published under Cement NewsThe 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 discovered. Figure 1: alite in the bottom right quadrant contains inclusions of free lime due to a high SO 3 content in the clinker (© A Harrisson) In the past couple of decades the cement industry has seen a number of changes in technology and priorities, which... |
Cost savings on the road to net-zero12 December 2023, Published under Cement NewsThe 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 INFORM explores how AI can reduce costs, lower carbon emissions and enhance customer service in cement logistics. By Dr Lars Lambrecht and Karsten Horn, INFORM GmbH, Germany. Figure 1: contributors to decarbonisation (Source: INFORM ) Even though Large Language Model... |
3D printing concrete: motivations, status and outlook11 December 2023, Published under Cement NewsWhile 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 Building Materials, Zurich, Switzerland. Figure 1: 3D printing technology enables considerable material and carbon footprint savings (right) with structures consisting of ribbed slabs, reminiscent of Pier Luigi Nervi’s designs (left) M... |
SNCR: when the equation no longer holds28 November 2023, Published under Cement NewsThere 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 successful denitrification is failing. By Karin Koglbauer, DyCarnica, Austria. Figure 1: chemical DeNOx behaviour-ammonia vs urea (© DyCarnica) Selective non-catalytic reduction (SNCR) refers to selective flue gas denitrification without a catalyst at 800-1100˚C. G... |
CO2NTESSA’s net-zero vision27 November 2023, Published under Cement NewsThe 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 it to capture more than 700,000tpa of CO 2 and a store it onshore in the Bockovci-1 saline aquifer. By NEXE Group, Croatia. The co2ntessa project will see the implementation of oxyfuel-based carbon capture at NEXE’s cement plant in Našice, Croatia (© NEXE) NEXE ... |
Business models for utilisation of non-recyclable plastics in the Indian cement industry15 November 2023, Published under Cement NewsCo-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 Bhatiani, Research Triangle Institute (RTI), India, and Dr Kåre Helge Karstensen and Palash Kumar Saha, SINTEF, Norway. Of the total amount of collected waste in India, 19 per cent is sent to landfill sites such as the Okhla landfill in Delhi (© Research Triangle Institute... |
Carbon capture optimisation: add heat, reduce risk13 November 2023, Published under Cement NewsWhile 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 Thomas Paarup Pedersen, Andrea Meroni, Christian Riber and Burcin Temel Mckenna, Ramboll, Denmark. Figure 1: simple process flow diagram of a cement plant with carbon capture, CO2 purification and liquefaction, and export. Red lines indicate heat recovery and integrati... |
Heidelberg Materials’ journey to net-zero07 November 2023, Published under Cement NewsHeidelberg 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 plant in Norway almost 20 years ago, the cement producer has developed several CCS projects using a range of technologies. By S Federhen and A Burns, Heidelberg Materials, Germany. Figure 1: by 2030 Heidelberg Materials wants to reduce its CO2 emissions by 47 per cent when ... |
Ironing out the carbon emissions of clinker production17 October 2023, Published under Cement NewsThe 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 Pesce, Aniruddha Baral, Anna Simmons and Theodore Hanein, The University of Sheffield, UK. Figure 1: estimates of potential raw meal replacement, calcium replacement, and raw materials-related CO 2 savings by using different types of iron-rich waste products in differen... |
