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... |
Towards Germany’s first fully-decarbonised cement plant10 October 2023, Published under Cement NewsHeidelberg 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 storage value chain for an inland site and is expected to capture 700,000tpa of CO 2 from 2029. Here, the company outlines the project’s scope and set-up for full-scale carbon capture. By Heidelberg Materials, Germany. Construction of Heidelberg Materials’ GeZero CCUS proje... |

Unlocking the power of waste heat25 September 2023, Published under Cement NewsWaste heat is the largest unused energy resource in the world. Harnessing this untapped potential can be a game-changer. A flexible and proven technology, modular organic-Rankine cycle (ORC) waste heat recovery turns waste heat into electricity while improving business performance, reducing CO 2 emissions, and enhancing overall sustainability in energy-intensive cement production immediately. Through new technologies, ORC modules can now also be used for medium-sized and smaller plants. By ... |
Geopolymer cements to address the GHG challenge11 September 2023, Published under Cement NewsMineral carbonation is being explored within the cement and concrete industry to chemically convert CO 2 emissions into stable minerals leading to permanent CO 2 storage within cementitious materials. Teesside University, UK, is collaborating with nine other industrial partners to decarbonise the cement industry through innovative technology that supports the industrial-scale production of carbon-neutral geopolymer cement through the use of historical industrial by-products and wastes. By ... |
