South Korea: Seven cement producers have agreed to produce 3.77Mt of cement in the second quarter of 2022, up by 36% quarter-on-quarter from first-quarter 2022 levels, to alleviate a shortage. 380,000t of cement which would previously have been exported will now supply the domestic market instead. The Yonhap News Agency has reported that bituminous coal supply issues have hampered the domestic cement industry's ability to increase its production in line with demand growth. In the first quarter of 2022, South Korea's coal imports consisted of 54% Russian coal and 46% Australian coal, compared to 75% Russian and 25% Australian coal in 2021.

The government plans to invest US$764m between 2023 and 2030 in improving the sustainability of South Korean cement production, including moving it away from reliance on coal through increased alternative fuel use.

US: The California Department of Transportation (CalTrans) has approved the use of Portland limestone cement (PLC) in its projects. The California Nevada Cement Association (CNCA) says that the move has the potential to eliminate 25,500t/yr of CO₂ emissions.

The CNCA plans to achieve cement and concrete carbon neutrality by 2045 through three priority actions. These are investment in promising and critical long-term technologies (crucially carbon capture, utilisation and storage (CCUS) technologies), increased alternative fuel (AF) substitution and the acceptance of PLC for CalTrans projects. Thus, the latest CalTrans decision marks the establishment of one pillar of the CNCA’s ambitious plan for net zero.

Mexico: Cemex has published its 2021 Integrated Report. Under the report’s Climate Action section, Cemex recorded a 4.7% year-on-year decrease in its CO₂ emissions per tonne of cementitious material. Alternative fuel (AF) substitution rose to 29%, while its products’ average clinker factor fell to 75%. It was the first company to complete a global roll-out of its reduced-CO₂ cement and concrete range (Vertua). It established Science-Based Targets Initiative (SBTi)-verified well below 2°C 2030 climate action goals and joined the UN’s Race to Zero and the Business Ambition for 1.5°C coalition. It also became a founding member of the World Economic Forum’s First Movers Coalition for zero-carbon economic development.

The year also brought major Sustainability and Circular Economy milestones, including managing 57 times the volume of waste it sent to landfill, positively impacting 25m lives through its Social Impact Strategy and processing 61% of global sales through its Cemex Go digital sales platform. For the second consecutive year, its Net Promotor Score was 68, ‘substantially above’ the construction and engineering industry average.

Indonesia: Entsorga has dispatched two Spider bridge cranes and two Pelican feeding and dosing systems for the construction of two new solid recovered fuel (SRF) storage, feeding and dosing systems at Indocement Tunggal Prakarsa’s 11.9Mt/yr Citeureup cement plant in Bogor Regency. The systems will have a total capacity of 50t/hr. An advanced supervision system will monitor and control their 24-hour operation. The Italy-based supplier says that both lines are highly automated and will reduce both CO₂ emissions and fuel consumption.

CEO Francesco Galanzino “The systems will help the cement plant to maintain its 2030 sustainability commitments, in line with the policies of HeidelbergCement who is a real first mover in the path toward sustainability. Such project it is a very important step in a Country where environmental policies are in their early stage.”

Nigeria: Dangote Cement’s revenue grew by 33.8% year-on-year to US$3.33bn in 2021 from US$2.49bn in 2020. Its sales volumes rose by 13.8% to 29.3Mt from 25.7Mt driven by a strong domestic market, although international volume growth was strong. Earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 43.2% to US$1.65bn from US$1.15bn.

“Over the last two years, we have finalised the deployment of 6Mt new capacity in Nigeria. Looking ahead, we are now focused on a less capital-intensive expansion cycle, which includes building grinding plants across West and Central Africa to leverage and strengthen Dangote Cement’s regional integration. We are on track to deploy grinding capacity in Cote d’Ivoire and Ghana. In addition, our Alternative Fuel Project is at an advanced stage which aims to leverage waste management solutions, reduce CO₂ emissions, and source material locally. This year, we co-processed 89,000t of waste representing a 60% increase over 2020,” said chief executive officer Michel Puchercos.

The group noted that Cement demand in Nigeria was sustained by increasing housing infrastructure, commercial construction, and government projects including major highways, roads, and railways. In May 2021 it re-started exporting clinker from its Onne and Apapa terminals and delivered seven clinker shipments with a total volume of 197,000t in 2021. It also exported 706,000t in 2021 by road to Togo and Niger. Internationally, the group said that it performed well but it also faced challenges in Cameroon, Ghana and Sierra Leone, where freight costs had increased substantially, causing volatility in the landing cost of cement and clinker.

Indonesia: Semen Indonesia has blamed falling earnings in 2021 on increased competition, production overcapacity and mounting coal prices. Its revenue fell slightly to US$2.43bn. However, its earnings before interest, taxation, depreciation and amortisation (EBITDA) dropped by 9.3% year-on-year to US$572m in 2021 from US$630m in 2020. Its sales volumes were driven by international sales, with domestic sales remaining stable at 32.2Mt. Foreign sales grew by 7.7% to 8.3Mt. Overall sales volumes increased by 1.6% to 40.5Mt from 39.8Mt.

In order to tackle its fuel costs the company says it has increased its use of alternative fuels, both biomass and non-biomass, and is optimising its coal consumption index by maintaining stable coal quality. It has also integrated coal procurement into the group to help better secure competitive pricing, supply and quality.

Turkey: Çimsa Çimento revenue grew by 80% year-on-year to Euro240m in 2021 from Euro133m in 2020. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 46% to Euro41.4m from Euro28.5m. The subsidiary of Sabancı Holding says that 54% of its sales in 2021 came from foreign sales. However, it noted that its production energy costs increased by 94%. It also reported that its alternative fuels substitution rate hit 15%.

“In July 2021 we took over the Buñol Factory in Valencia, Spain with Cimsa Sabancı Cement. With the addition of the Buñol Factory to our production and distribution network, we have strengthened our export network and expanded our sphere of influence in Europe, North Africa and South America,” said chief executive officer Umut Zenar. With the acquisition of the white cement plant in Spain, Çimsa Çimento says it has become one of the largest white cement producers in the world.

Germany: Australia-based FCT Combustion has successfully delivered a new Turbu-Flex burner to replace the existing burner at HeidelbergCement’s Hanover, Lower Saxony, cement plant. FCT Combustion will also supply burner accessories and add-ons, an igniter, a flame sensor, fans, blowers and spare parts. The project aims to improve combustion control and maximise alternative fuel (AF) use in the plant’s cement production.

US: Lafarge North America has reported that its Paulding, Ohio, plant achieved 99% alternative fuel (AF) substitution in its cement production, up from 95% in past years. The operator said that the fuel change saved 205,000t of CO₂ emissions in 2021.

Australia: Boral plans to install chlorine bypass technology at its Berrima cement plant in New South Wales. The Illawara Mercury newspaper has reported that the installation will help the plant to double its alternative fuel (AF) substitution rate to 100%. This is one of the ways in which the producer aims to reduce its Scope One and Two emissions by 46% between 2020 and 2030.

In mid-February 2022, Boral acquired new land at the site of its Dunmore quarry, also in New South Wales.
