HeidelbergCement’s latest sustainability target has been to reduce the ‘cement’ footprint from its own name. From this week it has become Heildelberg Materials. Of the top ten global cement producers in Global Cement Magazine’s roundup in the December 2021 issue only three now have the word ‘cement’ in their names.

In Heildelberg Materials’ own words, the “new brand identity underlines the company's pioneering role on the path to carbon neutrality and digitalisation in the building materials industry.” Chair Dominik von Achten then goes on to explain that the company is proud of its cement business but its range of services goes far beyond cement. This is certainly true but in 2021 the cement business generated 44% of the group’s revenue. 19% came from aggregates, 25% from ready-mixed concrete plus asphalt and the remaining 12% from services and other lines.

Yet, Heidelberg Materials is also a leader in driving innovation in carbon capture, utilisation and storage (CCUS) for the cement sector with a full production line capture unit planned for commissioning in 2024 at the Brevik plant in Norway. When it opens it will be the only full scale CCUS unit at a cement plant anywhere in the world. The group further plans to reduce the CO₂ footprint of its cementitious products to below 500kg/t CO₂ by 2030 and aims to generate half of its revenue from low-carbon products. These are not small achievements or ambitions.

Meanwhile, Holcim completed the divestment of its Indian business to Adani Group this week for US$6.4bn. For Holcim the move marks a milestone in the reshaping of its business away from developing markets and the diversification on its product lines into light (and more sustainable) building materials. So why would a company like Adani Group move into the cement sector when multinationals are getting out?

Money is the obvious answer and the one group owner Gautam Adani raised at a speech marking his latest mega-acquisition. He said, “Our entry into this business is happening at a time when India is on the cusp of one of the greatest economic surges seen in the modern world.” He expects his new cement arm to become the most profitable cement producer in the country although his competitors may have other ideas. As well as operational efficiency, Adani also plans to inject US$2.5bn into the business as part of plans to increase its production capacity to 140Mt/yr in the next five years, from around 70Mt/yr at present. However, the financial press in India and elsewhere has wondered how much debt Adani Group can cope with and whether it will consolidate its latest acquisitions or simply use them to buy into even more sectors. Time will tell.

Lastly, it should be noted that Adani Group’s new rival UltraTech Cement has targeted a production capacity of 154Mt/yr by 2025. Any growth in the Indian market will clearly be contested. It is also worth noting that the latter company has retained ‘cement’ in its name. For now at least.

Germany: The former HeidelbergCement launched its new name and branding as Heidelberg Materialsat a group level on 20 September 2022. The new two-word moniker underlines the cement producer's pioneering role on the path to building materials digitisation and carbon neutrality. 'Materials' stands for its innovative portfolio of sustainable and intelligent building materials, as well as digital solutions. The group's subsidiaries will also change their names to Heidelberg Materials from the beginning of 2023. Among the first to undergo the transformation will be US-based Lehigh Hanson, which will become Heidelberg Materials in early 2023.

Managing board chair Dominik von Achten said “We are proud of our cement business, but the company's range of services goes far beyond cement. Today, and even more in the future.Our future is sustainable. Our future is digital. Customer demands, markets and competitors are changing rapidly. Opportunities and challenges go beyond country borders; communication is becoming increasingly global. Differentiation opportunities arise." Concerning the company's cement business, von Achten said "We will be the first company in the world to offer carbon-free cement at large scale as early as 2024. We are vigorously driving forward the scaling of our CCUS activities: by 2030, we will reduce our CO₂ emissions by 10Mt/yr with the projects we have already launched. "

Denmark: Lime and chalk producer Dankalk has ordered a three-tube dryer type TRT 3150/5,0 from Germany-based Gebr. Pfeiffer. The order replaces a previous dryer also supplied by Gebr. Pfeiffer. Dankalk manufactures lime products for agricultural purposes, products for waste incineration plants and chemical auxiliaries and polymers for industrial wastewater treatment and environmental processes.

Zimbabwe: Government capital controls are delaying the handover of a new vertical cement mill ordered from China-based CBMI to Lafarge Zimbabwe. The cement producer still owes the supplier US$5.2m but has been unable to make the payment due to economic measures the government has taken to avoid depreciation of the local currency, according to the The Insider newspaper. The subsidiary of Switzerland-based Holcim is unable to obtain a certificate of completion from the supplier until the transaction has been completed. CBMI handled the order and Germany-based Gebr. Pfeiffer supplied the mill. The outstanding debt to CBMI may also delay Holcim’s deal to sell Lafarge Zimbabwe to Fossil Mining, which was announced in June 2022.

Europe: RHI Magnesita is heading a European Union Horizon project called ReSoURCE. The project seeks to develop a sensor-based refractory waste sorting and powder handling system. It involves academic partners in Austria, Germany, Ireland, Norway and the UK. The European Health and Digital Executive Agency (HADEA) supplied Euro6m in funding for the study, while the UK government supplied Euro1m. Global refractory waste generation is currently 28Mt/yr.

RHI Magnesita chief executive officer Stefan Borgas said “On average, 60% of all spent refractories generated by refractory-consuming industries go to landfill, while only 30% are recycled. With the ReSoURCE project, we aim to increase it up to 75%. This means we can achieve significant savings of CO₂ emissions per annum. With this research project, we have the chance to make a difference in the world.”

Pakistan: Germany-based Menzel Elektromotoren has revealed work on a replacement motor it has built for an unnamed cement plant in Pakistan. As part of the project it has designed a motor to fit a limited installation space that could drive the unit’s raw mill, another cement mill or a fan.

The engineering company’s solution was a compact slip ring motor in frame size 710 with the cooling system tailored to fit around a steel girder in the cement plant. To accommodate the existing couplings in two different sizes, Menzel designed the replacement motor with two shaft ends with different diameters. The motor output is configured to ensure efficient continuous operation in each of the three applications. The machine has a rated output of 4600kW and a rated voltage of 6300V. It complies with protection class IP55. At the customer's request, it was designed in cooling type IC 666, with permanent external ventilation of the inner and outer cooling circuit. Before delivery, Menzel also ran a load test in its in-house test field with the end-user attending via video streaming.

South Korea: Ssangyong Cement has ordered equipment from Germany-based KHD Humboldt Wedag as part of an upgrade to clinker production line five of the Donghae plant. The scope of supply for the contract includes: a Pyroclon R type calciner with Pyrotop mixing chamber; a Pyrorotor type alternative fuel combustion reactor; a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage four cyclones with new high-efficiency cyclones for calciner connection and an overall pressure drop reduction; a new kiln inlet chamber with orifice, kiln hood and tertiary air ducts; and a new Pyrofloor PFC 738AW type cooler with a Pyrocrusher PRC 420-4ES.

This project will be the fourth Pyrorotor installation at the Donghae plant. KHD’s scope includes the engineering and supply of mechanical equipment for the clinker production as well as electrical equipment for the overall modernisation of the production process. The project scope is the same as the modernisation contract of line four of Donghae plant, which was signed in February 2021 and currently is in commissioning. The commissioning of the modernised line five is scheduled for the fourth quarter of 2023.

South Korea: Halla Cement has awarded a supply and engineering contract to Germany-based KHD Humboldt Wedag for an upgrade of line 2 at Okke plant. KHD will supply a new Pyroclon R type calciner, with a Pyrotop type mixing chamber, and a 4.2m x 15m Pyrorotor type combustion reactor. Other equipment being provided includes: a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage five cyclones with new high-efficiency cyclones; and a new kiln inlet chamber with orifice. Erection and commissioning of the modernised production line is scheduled for the first quarter of 2024.

This latest project marks the second installation of a Pyrorotor at Halla Cement’s Okke plant. The installation of line 3 at the site is currently ongoing with commissioning scheduled for the first quarter of 2023. Overall, this will be KHD’s ninth installation of a Pyrorotor in South Korea.

The Pyrorotor has been promoted to cement plants as a way of using low-quality alternative fuels with minimal pre-processing. It offers a thermal substitution rate of over 85% and will also allow the Okke plant to reduce its NO_x emissions. The installation of the new Pyroclon R type calciner and the high-efficiency cyclones in the lowest preheater stages will also provide the production line with an increase in efficiency due to an overall pressure drop reduction in the entire preheater.

India: Adani Cement Industries has ordered a MVR 3750 C-4 type vertical roller mill from Germany-based Gebr. Pfeiffer for a new 165t/hr cement grinding plant it plans to build at Dahej in Gujarat. The order also includes an integrated SLS 4000 VC type classifier and a drive with a rated power of 3090kW. The subsidiary of Adani Group will produce fly ash-pozzolan mixed cement at the site.

Gebr. Pfeiffer’s local subsidiary, Gebr. Pfeiffer (India), will act as the general contractor for the project and will provide plant engineering. The commissioning of the new mill is planned for the period before the rainy season in the summer of 2023.
