Cemex chief participates in First Movers Coalition panel at COP27
09 November 2022Egypt: Cemex’s chief executive officer (CEO) Fernando A González was part of the First Movers Coalition panel at the 2022 United Nations Climate Change Conference (COP27) in Sharm El Sheikh on 8 November 2022. He participated alongside the World Economic Forum’s president Borge Brende, Microsoft president Brad Smith, ReNew chair and managing director Sumant Sinha, Volvo Group chief purchasing officer Andrea Fuder and US Special Climate Envoy John Kerry.
Cemex is a founding member of the First Movers Coalition, a partnership between the World Economic Forum and the US Office of the Special Presidential Envoy for Climate, John Kerry. It is the only buyers’ club working to scale new technologies across the heavy industry and heavy-duty transport sectors.
As a First Movers Coalition member, Cemex committed to making 32% of its heavy-duty transport purchases zero emissions by 2030. This commitment aligns with the company’s ambitious goals of reducing transport carbon emissions by 30% by 2030 and becoming net zero by 2050, part of its Future in Action program to achieve sustainable excellence and become a net zero CO2 company.
This commitment is particularly challenging, as zero-emission heavy-duty transport is presently unavailable at scale. At the panel, Fernando A Gonzalez talked about how collaboration and innovation are at the core of his company’s efforts. Cemex is already piloting fully electric concrete mixer trucks with partners like Volvo. It is also investing in transition technologies such as natural gas, replacing 200 diesel trucks with this lower-emission alternative in 2022.
Cemex will a host a discussion panel called Working Together to Decarbonise the Construction Value Chain, to be moderated by Thomas Guillot, chief executive of the Global Cement and Concrete Association (GCCA), on 10 November 2022. The panelists will include Diane Hoskins (Gensler Co), Aniruddha Sharma (Carbon Clean), Hubertus Meinecke (BCG) and Adair Turner (Energy Transitions Commission), in addition to Cemex’s Fernando A González.
Slashing cement's CO2 emissions Down Under
02 November 2022In 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.

GCCA signs memorandum of understanding with UCLG Africa
31 August 2022Gabon: The Global Cement and Concrete Association (GCCA) and the United Cities and Local Government of Africa (UCLG Africa) have signed a memorandum of understanding (MOU) at Africa Climate Week 2022 that is intended to collaboration towards decarbonising cement and concrete industries in Africa. The MOU was signed by UCLG Africa’s Secretary General Jean-Pierre Elong-Mbassi and the GCCA’s Director of Concrete and Sustainable Construction Andrew Minson. The agreement was made during Africa Climate Week 2022 in Gabon and sets out how both parties will work together to strengthen stakeholder advocacy towards net zero and encourage local governments to take policy action towards decarbonisation targets.
Through this agreement the two organisations will work together towards building sustainable and resilient cities, with a focus on an initial first five pilot cities to scope out opportunities and challenges. The two parties will jointly organise events that strengthen advocacy for the involvement of local governments in decarbonisation. Both parties will also aim to help make low carbon cement manufacturing more attractive to investors in Africa, as well as stimulate demand for low-carbon concrete products and to cultivate a positive environment for circular and Net Zero manufacturing across Africa.
To reach these objectives, both parties will work to ensure African cities have more capacity to embrace innovative cement products and that these cities can be mobilised effectively to join the Net Zero by 2050 efforts. GCCA and UCLG Africa will also look to build stakeholder support for multi-level governance in urban planning and housing across Africa.
Colombia: Federación Interamericana del Cemento (FICEM) and the Global Cement and Concrete Association (GCCA) have announced their next steps to accelerate the decarbonisation of cement production in Latin America and the Caribbean. The partners have named Colombia as the region’s first Net Zero Accelerator host country. The initiative works to identify barriers to decarbonisation and to recommend policy changes to make an immediate impact. Along with fellow Net Zero Accelerator host countries Egypt, India and Thailand, Colombia brings the total coverage of the initiative to 10% of global cement capacity.
GCCA chief executive officer Thomas Guillot said “The urgency of addressing climate change becomes clearer every day. Last year, our industry made a breakthrough Net Zero global commitment to reduce our carbon footprint, and we are now driving action in Latin America to make real change in one of the regions predicted to use the most concrete and cement in the coming decades. Our Roadmap Accelerator programme, previewed today by our members and affiliate (FICEM) at Latin America and the Caribbean Climate Week, highlights the tailored policies and tools we will use to ensure that Net Zero concrete and cement is achieved by 2050.”
Holcim Deutschland’s Lägerdorf cement plant to receive oxyfuel kiln and carbon capture system
18 July 2022Germany: Holcim Deutschland announced a planned upgrade to its Lägerdorf cement plant’s kiln on 14 July 2022. The producer will install a second generation oxyfuel kiln, which uses an air separation unit to supply oxygen directly, emitting CO2-rich flue gas. A new carbon capture system will supply captured CO2 to a synthetic hydrocarbons plant, which will produce methanol for other industrial applications. The upgrade will result in the capture of 1.2Mt/yr
of CO2 emissions and make Lägerdorf one of the world’s first carbon neutral cement plants, according to Holcim Deutschland.
The project, called Carbon2Business, was among four cement plant projects and 13 other EU-wide projects to win a share of a US$1.81bn EU Innovation Fund funding pot. CEO Thorsten Hahn acknowledged that the awarding of funds was ‘good news for Holcim and all partners working with us to decarbonise cement.’ He said “Climate change means cement change.”
