The group’s recurring earnings before interest, taxation, depreciation and amortisation (EBIT) rose by 16% to US$643m from US$553m. The company has upgraded its outlook 2022 to a forecast of full-year net sales growth of at least 10%.
CEO Jan Jenisch said “I am very encouraged by the record start of the year, setting a solid foundation to our Strategy 2025 – Accelerating Green Growth.”
The first quarter of 2022 brought four new bolt-on acquisitions in addition to the group’s conclusion of its US$1.35bn Malarkey Roofing Products acquisition. The company says that it remains actively engaged in supporting humanitarian efforts in Ukraine.
Holcim has also published its industry-first Climate Report 2022. The report details the company’s progress towards achieving its sustainability targets under the four pillars of its Strategy 2025 – Accelerating Green Growth. Under the Accelerating Growth pillar, Holcim reached a total of 15 markets with its ECOPlanet reduced-CO2 cement range. Under Expanding Solutions & Products, it reduced the proportion of cement sales in its consolidated sales to 57% in 2021 from 60% in 2020. Its other pillars are Leading in Innovation and Sustainability and Delivering Superior Performance. In 2021, the company used 6.6Mt of recycled construction and demolition waste in its products, against a 2050 target of 10Mt.
Chief sustainability and innovation officer Magali Anderson said “On our net-zero journey, we are walking the talk at Holcim, taking clear science-driven action to win the race for climate.”
World Cement Association calls for Middle East and North African cement sector decarbonisation
22 April 2022Middle East/North Africa: The World Cement Association (WCA) has called on its members in the Middle East and North African cement sectors to take new actions towards industry decarbonisation. UAE-based consultant and WCA member A3 & Co has said that companies in the region have the potential to cut their carbon footprints by up to 30% with no new capital expenditure required. The Middle East and North Africa accounted for 15% of global cement production in 2021. In the region, only the UAE and Saudi Arabia have committed to national net zero carbon targets, for 2050 and 2060 respectively.
WCA CEO Ian Riley said “There has been a lot of discussion in Europe and North America about decarbonisation roadmaps for the cement industry and good work has been done to start on this journey. However, 90% of the world’s cement is produced and used in developing countries; to impact overall industry emissions we must include these stakeholders. Cement companies in the Middle East have some low hanging fruit to take advantage of, which will lower costs at the same time as reducing CO2 emissions. At WCA we have a number of programmes that can help them realise this opportunity."
Canada: Carbon Upcycling Technologies has secured US$6.15m in financing from a group of companies led by Clean Energy Ventures, Cemex Ventures, Amplify Capital and Oxy Low Carbon Ventures (OLCV). The investment round includes participation from Zero Carbon Partners, Purpose ESG, Clean Energy Venture Group, Fund for Sustainability and Energy, Prithvi Ventures, Bryan Trudel, and Mark and Faye McGregor. Carbon Upcycling intends to use the funding to grow its team and build its second commercial-scale facility in North America, with a production capacity of over 200t/day of its cement and concrete additive. Carbon Upcycling sequesters CO2 in secondary cementitious materials such as fly ash, which are then used in cement or concrete production.
France: CRH subsidiary Eqiom has successfully commissioned its Gennevilliers construction waste recycling pilot plant. Prior to the plant’s opening, Eqiom recycled 10,000t of construction waste in the first quarter of 2022. It is now aiming to recycle 50,000t in 2022.
The company says that its continual efforts are making the circular economy possible in the construction sector.
US: CalPortland has converted production at the 1.3Mt/yr Mojave cement plant in California to its Advancement HS, a Portland limestone cement (PLC) product. The plant will reduce its CO2 emissions by 10% on a per ton basis. The company said the move supported the Portland Cement Association’s Roadmap to Carbon Neutrality and the industry’s overall efforts to address climate change.
Germany: Mexico-based Cemex has joined a consortium with Sasol EcoFT and Enertrag that plans to use CO2 and hydrogen to produce aviation fuel. The project is part of Cemex’s Future in Action program and is part of its plan to develop a carbon neutral operation at its Rüdersdorf cement plant by 2030. The consortium will source green hydrogen generated from wind and solar energy from Enertrag. The CO2 will come from the Rüdersdorf cement plant, which will provide 100t/day CO2 in the project’s initial stages. Sasol will then contribute its technology to produce e-kerosene, which, once certified, can be blended to constitute up to 50% of jet fuel.
The Rüdersdorf carbon neutral alliance includes over 20 start-ups, universities, companies from other industries and authorities working to develop industrial-scale solutions achieve the first carbon-neutral cement plant in the world.
Enertrag is a renewable-energy company based in Brandenburg. It operates utility-scale integrated energy plants in 10 countries. Its plants produce electricity and green hydrogen from wind and solar sources.
Sasol EcoFT is part of Sasol Group. It uses its technology to produce sustainable fuels and chemicals from green hydrogen and sustainable carbon sources, via the Power-to-Liquids process.
Switzerland: The latest report from the Intergovernmental Panel on Climate Change (IPCC) has informed policymakers that the best current route to reduce carbon emissions from cement production is through the increased use secondary cementitious materials and by encouraging the development and uptake of carbon capture. Alternatively, the development of new chemistries for building materials could help the situation but this is not expected in the short to medium term.
The report noted that 12Gt of CO2 equivalent was released directly and indirectly in 2019 from buildings and emissions from cement and steel use for building construction and renovation. These emissions included indirect emissions from offsite generation of electricity and heat, direct emissions produced onsite and emissions from cement and steel used for building construction and renovation. In sections of the IPCC report yet to be finally approved the authors said, “Cement and concrete are currently overused because they are inexpensive, durable, and ubiquitous, and consumption decisions typically do not give weight to their production emissions.”
Overall, the report concluded that average annual global greenhouse gas emissions from 2010 to 2019 were at their highest levels in human history but the rate of growth had slowed. The IPCC has called on “immediate and deep emissions reductions across all sectors” for any chance for society to limit global warming to 1.5°C. To do this global greenhouse gas emissions would have to peak before 2025 at the latest and be reduced by 43% by 2030. However, even if this did occur, it would take until the end of the 21st century for the temperature threshold to be stabilised.
