Germany: Heidelberg Materials has reported that it has increased its revenue by 13% year-on-year to Euro15.8bn during the first nine months of 2022. It said that high energy and raw material costs seen during the third quarter were only partly offset. The group’s net result for the nine-month period showed a 6.1% decline to Euro2.72bn. The decline was also due to significantly higher energy prices and increased raw material costs, which Heidelberg Materials said could only be offset partially by energy savings, cost discipline and price increases.

In the first nine months of 2022, sales volumes in all business lines declined due to consolidation and the economic impact from the Russian-Ukraine war on the European economy. Cement and clinker sales reduced by 6% to 90.0Mt, compared to 95.7Mt in the first nine months of 2021. Heidelberg Materials cited capacity reduction in North America, specifically its Western US operations, and the economic downturn in Europe as factors. Excluding consolidation effects, cement and clinker sales were down by 3.8%.

Heidelberg Materials said that it forecasts increased revenue for 2022, which will be adversely affected by increased outgoings. It expects global demand for building materials to weaken slightly on the back of higher costs and inflationary pressures.

Spain: Votorantim Cimentos Spain has completed its acquisition of Heidelberg Materials' businesses in the south of Spain. Under the deal, Votorantim Cimentos Spain gains control of FYM's 1.6Mt/yr Málaga cement plant, as well as three aggregates quarries and 11 ready-mix concrete plants in Andalusia.

Brazil-based Votorantim Cimentos' Europe, Asia and Africa CEO Jorge Wagner said “This acquisition is fully aligned with our strategy, reinforces our presence in the Iberian Peninsula to better serve our customers and creates significant synergies with our existing assets. Besides this, it will be key to accelerating our decarbonisation journey to achieve our 2030 Sustainability Commitments."

Votorantim Cimentos Spain operates six Spanish cement plants with 6Mt/yr in integrated capacity across Andalusia, the Canary Islands, Castile and León, Extremadura and Galicia.

In Australia and New Zealand, four producers operate a total of six integrated cement plants, with another 13 grinding plants situated in Australia. This relatively small regional cement industry has been on a decades-long trajectory towards ever-greater sustainability – hastened by some notable developments in recent weeks.

Oceania is among the regions most exposed to the impacts of climate change. In Australia, which ranked 16th on the GermanWatch Global Climate Risk Index 2021, destructive changes are already playing out in diverse ways.¹ Boral reported 'significant disruption' to its operations in New South Wales and southeast Queensland due to wet weather earlier in 2022. This time, the operational impact was US$17.1m; in future, such events are expected to come more often and at a higher cost.

Both the Australian cement industry and the sole New Zealand cement producer, Golden Bay Cement, have strategies aimed at restricting climate change to below the 2° scenario. Golden Bay Cement, which reduced its total CO₂ emissions by 12% over the four-year period between its 2018 and 2022 financial years, aims to achieve a 30% reduction by 2030 from the same baseline. The Australian Cement Industry Federation (CIF)'s 2050 net zero cement and concrete production roadmap consists of the following pathways: alternative cements – 7%; green hydrogen and alternative fuels substitution – 6%; carbon capture – 33%; renewable energy, transport and construction innovations – 35% and alternative concretes – 13%, with the remaining 6% accounted for by the recarbonation of set concrete.

Australia produces 5.2Mt/yr of clinker, with specific CO₂ emissions of 791kg/t of clinker, 4% below the global average of 824kg/t.² Calcination generates 55% of cement’s CO₂ emissions in the country, and fuel combustion 26%. Of the remainder, electricity (comprising 21% renewables) accounted for 12%, and distribution 7%. Australian cement production has a clinker factor of 84%, which the industry aims to reduce to 70% by 2030 and 60% by 2050. In New Zealand, Golden Bay Cement's main cement, EverSure general-purpose cement, generates CO₂ at 732kg/t of product.³ It has a clinker factor of 91%, and also contains 4% gypsum and 5% added limestone.

Alternative raw materials

Currently, Australian cement grinding mills process 3.3Mt/yr of fly ash and ground granulated blast furnace slag (GGBFS). In Southern Australia, Hallett Group plans to commission its upcoming US$13.4m Port Augusta slag cement grinding plant in 2023. The plant will use local GGBFS from refineries in nearby Port Pirie and Whyalla, and fly ash from the site of the former Port Augusta power plant, as well as being 100% renewably powered. Upon commissioning, the facility will eliminate regional CO₂ emissions of 300,000t/yr, subsequently rising to 1Mt/yr following planned expansions. Elsewhere, an Australian importer holds an exclusive licencing agreement for UK-based Innovative Ash Solutions' novel air pollution control residue (APCR)-based supplementary cementitious material, an alternative to pulverised fly ash (PFA), while Australian Graphene producer First Graphene is involved in a UK project to develop reduced-CO₂ graphene-enhanced cement.

Golden Bay Cement is investigating the introduction of New Zealand's abundant volcanic ash in its cement production.

Fuels and more

Alternative fuel (AF) substitution in Australian cement production surpassed 18% in 2020, and is set to rise to 30% by 2030 and 50% by 2050, or 60% including 10% green hydrogen. In its recent report on Australian cement industry decarbonisation, the German Cement Works Association (VDZ) noted the difficulty that Australia's cement plants face in competing against landfill sites for waste streams. It described current policy as inadequate to incentivise AF use.

Cement producer Adbri is among eight members of an all-Australian consortium currently building a green hydrogen plant at AGL Energy’s Torrens Island gas-fired power plant in South Australia.

Across the Tasman Sea, Golden Bay Cement expects to attain a 60% AF substitution rate through on-going developments in its use of waste tyres and construction wood waste at its Portland cement plant in Northland. The producer will launch its new EcoSure reduced-CO₂ (699kg/t) general-purpose cement in November 2022. In developing EcoSure cement, it co-processed 80,000t of waste, including 3m waste tyres. The company says that this has helped in its efforts to manage its costs amid high coal prices.

Carbon capture

As the largest single contributor in Australia's cement decarbonisation pathway, carbon capture is now beginning to realise its potential. Boral and carbon capture specialist Calix are due to complete a feasibility study for a commercial-scale carbon capture pilot at the Berrima, New South Wales, cement plant in June 2023.

At Cement Australia's Gladstone, Queensland, cement plant, carbon capture is set to combine with green hydrocarbon production in a US$150m circular carbon methanol production facility supplied by Mitsubishi Gas Chemical Company. From its commissioning in mid-2028, the installation will use the Gladstone plant's captured CO₂ emissions and locally sourced green hydrogen to produce 100,000t/yr of methanol.

More Australian cement plant carbon capture installations may be in the offing. Heidelberg Materials, joint parent company of Cement Australia, obtained an indefinite global licence to Calix's LEILAC technology on 28 October 2022. The Germany-based group said that the method offers effective capture with minimal operational impact.

Cement Australia said “The Gladstone region is the ideal location for growing a diverse green hydrogen sector, with abundant renewable energy sources, existing infrastructure, including port facilities, and a highly skilled workforce." It added "The green hydrogen economy is a priority for the Queensland government under the Queensland Hydrogen Industry Strategy.”

Logistics

Australian and New Zealand cement facilities' remoteness makes logistics an important area of CO₂ emissions reduction. In Australia, cement production uses a 60:40 mix of Australian and imported clinker, while imported cement accounts for 5 – 10% of local cement sales of 11.7Mt/yr.

Fremantle Ports recently broke ground on construction of its US$35.1m Kwinana, Western Australia, clinker terminal. It will supply clinker to grinding plants in the state from its commissioning in 2024. Besides increasing the speed and safety of cement production, the state government said that the facility presents 'very significant environmental benefits.'

Conclusion

Antipodean cement production is undergoing a sustainability transformation, characterised by international collaboration and alliances across industries. The current structure of industrial and energy policy makes it an uphill journey, but for Australia and New Zealand's innovating cement industries, clear goals are in sight and ever nearer within reach.

Egypt: Suez Cement has partnered with Intro Power and Utilities for the construction of a 20MW solar power plant at its Suez cement plant. From its commissioning in early-mid-2023, the installation will provide the plant with 45GWh of energy annually, 20% of its annual consumption. Suez Cement says that this will eliminate 22,000t/yr-worth of CO₂ emissions. Construction is expected to cost US$350m and commence in 2023.

Suez cement aims to achieve specific CO₂ emissions of 400kg/t of cementitious product by 2030, down by 47% from 1990 levels.

Managing director Mohamed Hegazy said “Through transitioning to renewable solar energy, we are looking at long-term economic benefits, laying the foundation for a low-carbon business and energy security, without jeopardising the health of our environment. We are proud about this new milestone and to be one of the few cement players in Egypt taking this step towards using a more affordable and cleaner energy."

Germany: KHD hosted a meeting of the research and development consortium of the ACCSESS project in Cologne on 18 and 19 October 2022. The consortium is intended to develop replicable carbon capture utilisation and storage pathways to support a net zero strategy in Europe by 2050. KHD’s involvement with the project concerns running engineering feasibility studies for the retrofit of CCUS projects at two cement plants in Europe. It is also working on the concept development for a new clinker production technology, which is optimised as a new plant for operation with downstream carbon capture technology.

Other project partners working on ACCSESS of note to the cement sector include Heidelberg Materials and the German Cement Works Association (VDZ). Project completion is scheduled for mid-2025 with KHD’s contributions to be delivered by mid-2024.

India: HeidelbergCement India recorded consolidated sales of US$61.5m during the second quarter of its 2023 financial year, down by 11% year-on-year from US$69.2m in the second quarter of the 2022 financial year. The Heidelberg Materials subsidiary's net profit in the quarter fell by 88% over the year, to US$852,000 from US$7.24m in the 2022 financial year's second quarter. The second quarter of the 2023 financial year brought a 0.3% year-on-year drop in the producer's operating expenses, to US$55.7m from US$55.9m.

France: Heidelberg Materials' subsidiary Ciments Calcia has laid the foundation stone for its construction of a Euro285m CO₂ emissions-reducing upgrade to its Airvault cement plant in Nouvelle-Aquitaine. Ciments Calcia first published its plans for the installation of a new 4000t/day production line to replace both existing lines at the Airvault plant in 2021, with commissioning scheduled for mid-2024.

Germany-based ThyssenKrupp secured the order to supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 vertical roller mill, a 10,000t raw materials tangential blending silo, a single-string, five-stage Dopol cyclone preheater with integral calciner for alternative fuels (with the possibility of conversion to oxyfuel), a Polytrack clinker cooler, a solid recovered fuel preparation line and dedusting systems for the project.

Germany: Heidelberg Materials has reaffirmed its 2030 CO₂ emissions reduction targets and submitted them to the Science-Based Targets Initiative (SBTi) for review. These include a reduction in Scope 1 emissions per tonne of cementitious material of 47% between 1990 and 2030. The initiative will now ensure that the targets conform to a 1.5°C climate change scenario.

Heidelberg Materials chair Dominik von Achten said “We have been actively supporting SBTi’s efforts to develop a 1.5°C roadmap and impactful criteria for the cement industry. With the industry's most ambitious CO₂ reduction targets and a steadily growing portfolio of CCUS projects, we are eager to continue leading the way.”

Tanzania: The Fair Competition Tribunal (FCT) has blocked an attempt by Heidelberg Materials to buy a 68% stake in Tanga Cement for around US$59m saying it was contrary to the law. The Germany-based building materials producer announced in October 2021 that it had agreed to buy Tanga Cement from South Africa-based AfriSam via various subsidiaries, according to the Citizen newspaper. The Fair Competition Commission (FCC) provisionally approved the transaction but required the buyer to keep the operations of Tanga Cement running, to continue producing and promoting the Simba Cement (Tanga Cement) brand and to keep employing the existing staff at Tanga Cement. However, Chalinze Cement Limited and the Tanzania Consumer Advocacy Society opposed the decision due to a potential reduction in market competition and successfully made an appeal to the FCT.

In a statement Tanga Cement said that Heidelberg Materials and AfriSam were, “considering how to proceed, but the FCT ruling has placed the acquisition at great risk of not being implemented.” It added that the parties were waiting for a formal ruling from the FCT and would then seek further advice on how to proceed.

Germany: Heidelberg Materials says it is considering shutting down plants in Germany due to the high cost of gas and electricity. In comments reported by Reuters chief executive officer Dominik von Achten said, "If power prices won't come down sustainably, we would have to take individual plants in Germany completely off the grid. That's what we have prepared for." He added that the company is shifting production to times and days when power prices are lower including at the weekend. However, changing staff shift patterns has required ongoing discussions with labour unions.

The building materials company expects its energy bill to rise by around half year-on-year to over Euro3bn in 2022. It has called on the German government to place a cap on energy prices despite measures the company has already taken to protect itself from soaring costs, such as using alternative fuels.
