Germany: Cemex Zement’s Rüdersdorf, Brandenburg, cement plant is to host a new 100t/day carbon capture installation. Cemex Zement will collaborate with UK-based Carbon Clean on a front-end engineering and design (FEED) study for the project. The system will combine captured CO₂ with sustainably sourced hydrogen in order to produce green synthetic hydrocarbons. The partners aim to increase the system’s CO₂ capture capacity to 300t/day by 2026, before finally scaling it up to 2000t/day.

Europe, Middle East, Africa and Asia regional president Sergio Menendez said “This project with Carbon Clean is the latest development in Cemex’s plan to achieve carbon neutrality at the Rüdersdorf cement plant by 2030, through our pioneering carbon neutral alliance with expert industrial consortiums. Carbon capture will play a fundamental role in the efforts to succeed at this goal and ensure our operations are more sustainable.”

UK: Cemex has joined its subsidiary Cemex Ventures and Taronga Ventures in investing in construction logistics digital platform developer Voyage Control. The group said that the supplier’s product can reduce delays, waste and cost overruns through optimised delivery scheduling, and provide an overview of all transactions in real time. It currently helps to coordinate 6 million deliveries annually at 200 sites across North America, Europe and Asia.

Cemex Ventures director Gonzalo Galindo said “Cemex Ventures seeks to integrate Voyage Control with Cemex's digital assets, which will allow us to provide a better and more complete service to our clients. Now, we can collect more information, continue to promote operational efficiency and sustainable reporting and improve our health and safety criteria to reduce risks.”

Peru: Yura has appointed Fernando Rojasa as its general manager. He succeeds Julio Cáceres who was working the position on a provisional basis, according to the Gestión newspaper.

Rojas, a Costa Rican national, holds a degree in chemical engineering and a Master in Business Administration from the University of Costa Rica. He worked for Cemex for over a decade becoming the director of operations for cement and lime in Puerto Rico and then the director of sustainability optimisation for Central America and the Caribbean.

Cáceres, who worked as Yura's Commercial Management Manager for Cement, has been appointed as the new Commercial Director of Cementos, Concretos y Cal in Peru, Chile and Bolivia.

Spain: The large taxpayers unit of the Tax Agency has imposed a Euro63m fine on Cemex España for issues relating to past tax payments. The El País newspaper has reported that the fine follows an investigation of the company’s corporation tax payments between 2010 and 2014. The agency previously imposed a Euro456m fine on Cemex in 2011 for inflating its losses between 2006 and 2009.

In the two and a half years since Calix brought together cement producers across corporate and national boundaries to form the first Low Emissions Intensity Lime And Cement (LEILAC-1) consortium and commissioned a carbon capture installation at the Lixhe cement plant in Belgium on 10 May 2019, carbon capture and storage (CCS) has passed some major milestones. New installations have made Global Cement headlines from Canada (at Lehigh Cement’s Edmonton plant in November 2019) to China (at a China National Building Material (CNBM) plant in July 2021). Twelve other European cement plants now host current or planned carbon capture trials – including the first full-scale system, at HeidelbergCement’sBrevik plant in Norway. A second Calix-led project in Germany, LEILAC-2, attracted Euro16m-worth of funding from the European Union in April 2020.

The work of LEILAC-1 – backed by HeidelbergCement, Cemex, Lhoist, Tarmac and others, with Euro12m in funding – set the benchmark in innovation. Its pilot plant successfully captured 100% of 'unavoidable' process emissions by indirectly heating raw materials inside a vertical steel tube. Called direct capture, the model removes a CO₂ separation step, as our subsequent price analysis will reflect.

In October 2021, the LEILAC-1 consortium published its report of the concluded Lixhe trial. It described the three-fold key successes of the study:

1) Both limestone and raw meal may be processed;

2) CO₂ is successfully separated;

3) The energy penalty for indirect calcination is not higher than for conventional direct calcination.

Additionally, Calix’s first departure into the cement sector has demonstrated that its model exhibits no operational deterioration, does not suffer from material build-up and has no impact on the host plant when used in cement production. The plant’s clinker capacity remained the same as before the trial. Most importantly of all, the Lixhe cement plant recorded no process safety incidents throughout the duration of the trial.

The study has also put an evidence-based price tag on industrial-scale CCS at a cement plant for the first time: Euro36.84/t. Figure 1 (below) plots the full-cycle costs of three different carbon capture installations at retrofitted 1Mt/yr cement plants using 100% RDF, including projections for transport and storage. Installation 1 is an amine-based carbon capture system of the kind installed in the Brevik cement plant’s exhaust stack; Installation 2 is the Calix direct capture system and Installation 3 consists of both systems in combination. Direct capture’s costs are the lowest, while the amine retrofit and the combination installation are close behind at Euro43.68/t and Euro43.25/t respectively.

Installations 1 and 3 both entail additional energy requirements for the separation of CO₂ from flue gases and air. With the inclusion of the CO₂ produced thereby, the cost of Installation 1 rises to Euro94/t of net CO₂ emissions eliminated, more than double that of Installation 2 at Euro38.21/t. The combination of the two in Installation 3 costs Euro67.3/t, 76% more than direct capture alone. Figure 2 (below), breaks down the carbon avoidance costs for each one and compares them.

The Global Cement and Concrete Association (GCCA)’s seven-point Roadmap to Net Zero strategy puts CCS at the forefront of concrete sector decarbonisation. CCS is expected to eliminate an increasing share of global concrete’s CO₂ emissions, rising to 36% in 2050 – by then 1.37Bnt of a total 3.81Bnt. This will depend on affordability. Calix’s model has reduced the capital expenditure (CAPEX) of a carbon capture retrofit by 72% to Euro34m from Euro98m for the amine-based equivalent. When built as part of a new plant, the CAPEX further lowers to Euro27m. Both models may also be retrofitted together, for Euro99m. In future, Calix expects to install direct capture systems capable ofachieving Euro22/t of captured CO₂. By contrast, the cost of emitting 1t of CO₂ in the EU on 11 October 2021 was Euro59.15.

In what it calls the Decade to Deliver, the GCCA aims to achieve a 25% CO₂ emissions reduction in global concrete production between 2020 and 2030, in which CCS plays only a minor part of less than 5%. LEILAC-1 presents a visionof affordable carbon avoidance which complements cement companies’ 2030 CO₂ reduction aspirations.

Unlike conventional CCS methods, however, direct capture only does two thirds of a job – eliminating the emissions of calcination, but not combustion. This would appear to make it unsuited to cement’s longer-term aim of carbon neutrality by 2050 in line with the Paris Climate Accords’ 2°C warming scenario. On the other hand, direct capture is not designed to work alone. Calix recommends use of the technology in conjunction with a decarbonised fuel stream to eliminate the plant’s remaining direct emissions. This increases the price - by 47% to Euro56.05/t of CO₂ avoided for biomassand by more than double to Euro104.48/t for an E-kiln.

The Lixhe cement plant’s carbon capture story is one of a successful crossover from one industry into another: Calix previously applied the technology in the Australian magnesite sector. Realisation of the Calix carbon capture vision in the global cement industry is a challenge primarily due to the scale of the task. It will require continued collaboration between companies and with partners outside of the industry. Further than this, parliaments must continue to enact legislation to make emission mitigation the economic choice for producers.

US: Cemex USA has upgraded two Florida cement terminals, the Pensacola and Palm Beach terminals, at a cost of US$8m. The upgraded terminals will serve to increase Cemex USA’s cement supply to the region through marine shipments from its global operations. The Palm Beach terminal is also involved in the distribution of assorted cementitious materials including granulated blast furnace slag (GBFS) and fly ash for cement production.

USA executive vice president Matthew Wild said “Florida is growing rapidly, and Cemex’s strong network makes our company well-positioned to implement supply chain and operational enhancements to meet the high demand for building materials in Florida and beyond.” He added “On the cement side, increased demand has outpaced supply at times, and we expect our supply chain enhancements to help alleviate that issue.”

Mexico: Cemex has announced the release of the collateral on its debt under its main bank agreement and senior secured notes. The release follows Cemex’s reporting of two consecutive quarters with a consolidated leverage ratio of 3.75x or less.

CFO Maher A-Haffar said “We are very pleased with this momentous milestone, which is a culmination of the substantial strengthening of our capital structure and paves the way towards an investment grade rating. This will simplify our debt structure and reduce the cost of managing our debt stack.”

Mexico: Cemex CEO Fernando Gonzalez has estimated that the impacts of the Covid-19 outbreak will cost the group US$100m in 2021. Gonzalez attributed the anticipated negative effect on full-year earnings before interest, taxation, depreciation and amortisation (EBITDA) to supply chain disruptions and currency effects, especially on the Mexican Peso, as well as delays to projects globally.

Poland: Cemex Poland has established a new 50kW solar power plant at its Pruszków ready-mix concrete production plant in Masovian Voivodeship. The company says that it is planning other investments to retrofit renewable energy systems into its operations across Poland.

Materials director Michał Grys said “Cemex is actively addressing the climate challenge by decarbonising our processes. The key to realising our ambitious goals is finding and implementing new low-emission products as well as more sustainable technologies and construction solutions.” He added “Photovoltaic farms are another investment by Cemex Poland in renewable energy sources. Currently, much of the electricity used in our aggregate quarries, cement plants and many concrete plants comes from renewable sources."

Mexico: Cemex has received validation from the Science-Based Targets Initiative (SBTi) for its 2030 global CO₂ emissions reduction targets. The validation attests that the targets conform with the Paris Agreement’s well-below 2°C global warming limit. Under its Future in Action programme, Cemex aims to reduce its cement’s carbon footprint to 40% compared to 1990 levels and achieve 55% renewable energy use by 2030. The company says that it has the global cement industry’s most ambitious 2030 targets.

CEO Fernando Gonzalez said “Climate action is the biggest challenge of our times. Cemex is taking decisive action to address it by defining ambitious emissions reduction targets in line with the SBTi, and executing against those targets.” He added “We commit to continue leading the industry in climate action not only because it creates value, but more importantly because it is the right thing to do. Cemex is building a better future, and that future must be sustainable.”
