Germany/Australia: Calix subsidiary Leilac has concluded a licence agreement with Heidelberg Materials for use of its carbon capture technology. The cement producer holds the licence indefinitely and for all operations across the globe. It said that Leilac’s technology offers effective capture of unavoidable cement plant CO₂ emissions with minimal operational impact.

Heidelberg Materials currently has one Leilac system installed at its Lixhe plant in Belgium. It expects to commence construction of a second unit at its Hanover plant in Germany in 2023. Together, the installations will be able to capture 125,000t/yr of CO₂. The producer says that both projects pave the way for future full-scale deployment of Leilac’s carbon capture model.

Australia: Cement Australia’s Gladstone cement plant in Queensland will host a study of methanol production from green hydrogen and captured CO₂. Japan-based Mitsubishi Gas Chemical Company will supply its green methanol production technology, while hydrogen and oxygen feedstocks will be sourced locally. Cement Australia and Mitsubishi Gas Chemical Company will collaborate on commercialisation of their green methanol. Cement Australia said that carbon capture and its utilisation in value added products is a strategic pillar of the company’s decarbonisation roadmap.

The cement producer 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. The green hydrogen economy is a priority for the Queensland government under the Queensland Hydrogen Industry Strategy.”

Mexico: Cemex sold 47.8Mt of cement in the first nine months of 2022, down by 5.3% year-on-year from 40.5Mt in the same period of 2021. Despite this, its consolidated revenues rose by 8%, to US$11.7bn from US$10.8bn. The group's cost of sales grew by 12% to US$8.09bn from US$7.25bn, and its operating earnings before interest, depreciation, taxation, depreciation and amortisation (EBITDA) dropped by 6.6%. Nonetheless, contributions from discontinued operations led to net income growth of 72%, to US$987m from US$574m.

Cemex said that higher prices in local currency terms drove sales growth across all of its regions. As a percentage of sales, costs grew to 70% from 68%, mainly on account of energy price rises. Operating EBITDA fell across all regions apart from Europe, the Middle East, Africa and Asia (EMEAA), where it rose by 2.5% to US$524m from US$511m. Cemex noted Europe's 'remarkable resilience' in implementing 'double-digit' price increases to increase earnings, while also crossing a threshold of 40% in CO2 emissions reduction from its 1990 baseline.

Austria: Rail logistics company ÖBB Rail Cargo Group (RCG) says that its haulage of 80,000t/yr of granulated blast furnace slag (GBFS) and clinker to and from w&p Zement's Wietersdorf cement plant in Carinthia by rail has removed 3200 trucks/yr from the road since its start in 2019. RCG's trains deliver the plant's clinker to the Peggau-Deutschfeistritz railway station in Styria, and return to the plant laden with GBFS from steel producer Voestalpine's nearby Leoben refinery.

RCG said that w&p Zement is currently working to increase its operations' reliance on rail, adding "Further innovative transport solutions are already being worked on."

Germany: Ireland-based CRH has agreed to sell its subsidiaries Opterra Zement and Opterra Beton to Thomas Gruppe. Thomas Gruppe expects to complete its acquisition of the businesses later in 2022. Opterra Zement owns the 1.4Mt/yr Karsdorf, Saxony-Anhalt, cement plant and 0.5Mt/yr Sötenich, North Rhine-Westphalia, grinding plant, the latter of which is closed. Opterra Beton operates the Neufahrn, Bavaria, ready-mix concrete batching plant.

Thomas Gruppe said "For years, we have been pursuing a steady and long-term growth course in the field of cement and precast and ready-mix concrete. In the cement segment, our competitive position improved significantly with the purchase of the Erwitte (North Rhine-Westphalia) plant in 2017. Together with the grinding plant in Dorndorf (Thuringia), we have achieved a significantly larger area coverage in Germany, and also in the Netherlands, and benefit from synergy effects." It continued "We would like to continue on this growth course. An opportunity like the one to take over the cement plant in Karsdorf does not come often. The Karsdorf plant, with its gigantic limestone deposits, its market position of well over 1Mt/yr of cement and its experienced team, enables us better to supply our customers, and to leverage improvement potential. In addition, Karsdorf is of sufficient size for us to install CO₂ separation technology in its production of clinker for the Dorndorf grinding plant." Thomas Gruppe concluded "We are convinced that cement will become a clean building material and believe in its future."

Japan: Taiheiyo Cement has agreed to buy the cement business of chemicals company Denka for an undisclosed sum. Denka operates an integrated plant in Itoigawa City, Niigata Prefecture where Taiheiyo Cement’s subsidiary Myojo Cement also operates a plant. The three companies have been working on a joint-development plant for local limestone resources since 2018. However, Denka has decided to leave the cement market due to poor local demand and the necessity of upgrades at its plant from 2025 onwards.

From April 2023 cement sold from Denka’s Omi plant will carry the Taiheiyo Cement brand name. Taiheiyo Cement and Myojo Cement have also agreed to continue supplying Denka’s other businesses, such as carbide production, with limestone from 2025. Denka will send by-products and other waste streams to the cement producer. Finally, Taiheiyo Cement, Myojo Cement and Denka will carry on developing the local limestone resources near to Itoigawa City.

US: The Global Cement and Concrete Association (GCCA) has signed an international partnership agreement with the American Concrete Institute (ACI). Under the agreement, the partners will collaboratively develop and disseminate information on concrete production and its use in construction, with a view to advancing best practices in sustainability.

The ACI said "ACI cooperates closely with our international partners, benefitting everyone in the global concrete community. ACI looks forward to working with the GCCA towards a future where everyone has the knowledge needed to use the latest concrete technologies effectively to meet the demands of a changing world."

South Africa: Saudi Arabia-based ACWA Power and Industrial Development Corporation of South Africa (IDC South Africa) have partnered to explore the development of green hydrogen infrastructure opportunities in South Africa. Together, they will aim to accelerate the country's transition into a green hydrogen economy across industries including cement production. ACWA Power projected the potential value of developments at US$10bn.

South Africa is committed to achieving net zero CO₂ emissions by 2050.

ACWA Power's vice chair and chief executive officer Paddy Padmanathan said "As a company that is driving the energy transition, ACWA Power is proud to work closely with the IDC, with whom we share a robust working history, and today we are delighted to take our collaboration further. I am confident that our expertise in developing mega-scale green hydrogen projects in other geographies will enable us to successfully create a new avenue of sustainable energy generation - one that will pave the path to further progress.”

Pakistan: Bestway Cement has ignited the 7200t/day kiln at its new Mianwali integrated cement plant in Punjab Province. The plant has 20MW of dedicated solar power capacity and 9MW of waste heat recovery (WHR) power capacity.

Spain: Brazil-based Votorantim Cimentos' Córdoba, Niebla and La Araña cement plants in Andalusia are at the centre of a planned Euro1bn decarbonisation project by the company. Votorantim Cimentos will publish details of its plans, which include renewably powered green hydrogen and biofuels production, in early 2023.

Votorantim Cimentos Europe, Asia and Africa CEO Jorge Wagner said "We need agility with the administration, because the investments are stratospheric and long-term. We want to obtain subsidies, taking advantage of European funds." He concluded "We have the opportunity to carry out a very beautiful project in Andalusia and beat the Americans."
