US: The Environment Protection Agency (EPA) has awarded Cemex USA's Miami cement plant its 11th consecutive Energy Star or its on-going energy efficiency and sustainability efforts.

President Jaime Muguiro said "Sustainability and conservation are ingrained in our operations and our business, so we constantly seek opportunities to decrease our energy use and reduce environmental impacts." He added "Our team at our Miami cement plant is helping to set the standard for our industry, demonstrating what can be possible, and we are proud of their ongoing environmental performance and commitment."

US: LafargeHolcim US has revealed more information about a commercial-scale carbon-capture study based at its integrated Ste. Genevieve cement plant in Missouri. The project aims to deliver a front-end engineering design (FEED) study for a carbon capture retrofit that can separate up to 95% of CO₂ emissions at the plant. The captured CO₂ will be ‘pipeline ready’ for geological storage and analysis of the project socio-economic impact will also be part of the study. The US Department of Energy’s National Energy Technology Laboratory awarded US$4m to the Prairie Research Institute at the University of Illinois to work on the project in early October 2021. LafargeHolcim and Air Liquide are also making cost share contributions.

The design will use Air Liquide’s Crycocap FG system at the cement plant. LafargeHolcim US says that it combines pressure swing adsorption capabilities with cryogenic refrigeration technologies to achieve high CO₂ capture rates with high CO₂ purity rates. Notably, for a carbon capture project, the Ste. Genevieve plant has one of the largest single clinker kilns in the world.

The second unit, for the southeast region, will be delivered in the summer of 2022 with commissioning by the spring of 2023. Both unloaders will have a rated cement handling capacity of 300t/hr for vessels up to 5000 dwt. Other features include technology for diagnostics and trouble-shooting. The customer for the order has not been disclosed.

US: Eagle Materials’ consolidated sales were US$985m in the first half of the 2022 financial year, up by 13% year-on-year from US$875m in the first half of the 2021 financial year. Its gross profit rose by 25% to US$282m from US$225m. The group recorded cement sales of US$496m, up by 4.4% from US$475m in 2020.

World: A Systems Change Lab report on the state of climate change action has warned that the global cement industry is making insufficient progress towards its 2030 climate change targets and that a step-change in action is required. It recorded the carbon intensity of global cement production at 635kgCO₂/t in 2018 with the 2030 target of no more than 370kgCO₂/t. The rate of change over the previous five years was reported as being 2.9% but an annual rate of change of 22.5% would now be required to meet the 2030 target.

It also noted that emissions intensity from the cement industry had actually increased slightly in recent years. It reached this conclusion by using a different methodology from the Getting the Numbers Right (GNR) project. Instead it estimated the global emissions intensity by using global data on process emissions and energy data from the International Energy Agency and the GNR.

The report said that the cement sector would need to go beyond traditional mitigation options such as improving energy efficiency and switching fuels to meet its climate commitments. However, carbon capture utilisation and/or storage (CCUS) and novel cements were described as costly and immature. In its view, “Decarbonisation in the long term thus will depend on significant investments in research, development, and demonstration, alongside efforts to create a demand for low-carbon cements and policies to support investment in decarbonisation technologies.” It described both strategies as, “not yet fully mature in terms of technology development, costs and scaling.” The ‘critical enablers’ it identified to help the cement sector meet its target included stricter regulations, increased demand for low-carbon cement and investment in pilot and industrial scale projects looking at novel cements.

Overall, the report said that change towards averting climate change across 40 key areas in power generation, buildings, industry, transport, land use, coastal zone management and agriculture was not happening fast enough and that none were on track to meet their respective 2030 targets. Change was happening but not at the required pace. Systems Change Lab is a collaboration between the High-Level Climate Champions, Climate Action Tracker, ClimateWorks Foundation, the Bezos Earth Fund and World Resources Institute.

France/US: Fortera has appointed Thierry Legrand as the president of its European region. The company said that the addition of a president in Europe was the first step in creating a broader presence allowing for Fortera's carbon reducing cement to be deployed on a global scale.

Legrand previously worked for Lafarge and Holcim for over 25 years in European, Asian and African markets. During this time he became the country chief executive officer (CEO) in South Africa and Malaysia before finally becoming the Project Director Logistic Europe for LafargeHolcim between 2018 and 2020. Legrand follows former LafargeHolcim CEO Eric Olsen in joining Fortera. Olsen was appointed to Fortera’s board of directors in June 2021.

US: LafargeHolcim US and ECOncrete Tech have launched a research and development collaboration to design and manufacture a fully structural concrete scour protection unit for offshore wind turbines. The unit’s specifications include seabed stabilisation and promotion of the growth of marine organisms. The collaboration includes a large-scale pilot project to evaluate the ecological performance of units in an offshore environment. The US/Canada Binational Industrial Research and Development (BIRD) Energy programme are funding the project, which will conclude in May 2024.

LafargeHolcim US commercial excellence vice president Josep Maset said “There are many paths to achieving our net zero commitment, and most require innovative partnerships and out-of-the-box thinking. The work we’re doing with ECOncrete Tech is a notable example of searching for solutions that enable increased use of renewable energy in an environmentally responsible way.”

US: The Portland Cement Association (PCA) has published a roadmap to carbon neutrality for the cement and concrete sectors by 2050. It says that the strategy document demonstrates how the US cement and concrete industry, along with its entire value chain, can address climate change, decrease greenhouse gases and eliminate barriers that are restricting environmental progress. It added that the document is a ‘major step’ towards engaging US policymakers, industry partners and non-government organisations.

“Cement and concrete have been pivotal in building resilient, durable and sustainable communities that enable people to live safe, productive and healthy lives via structures that withstand natural and man-made disasters,” said PCA President and chief executive officer, Michael Ireland. “The PCA is uniquely positioned to lead the industry-wide ambition to achieving carbon neutrality and enable our member companies and industry partners to continue building a better future.”

The PCA’s roadmap outlines a number of reduction strategies across the various phases of the built environment including production at cement plants, construction including designing and building and everyday infrastructure in use. It also recognises five main areas of opportunity: clinker; cement; concrete; construction; and carbonation (using concrete as a carbon sink).

Notably goals include a reduction of coal and petcoke use at cement plants to 10% in 2050 from 60% at present, a clinker ratio of 75% in 2050 from 90% at present and a reduction of the CO₂ intensity of concrete of 60% by 2050. The roadmap also noted the necessity of carbon capture and storage/utilisation (CCUS) for reducing CO₂ emissions from cement production. However is pointed out that there are no commercial-scale CCUS installations at any cement plant within the US, location and permitting challenges remained and that infrastructure investment would be required to deal with the captured CO2.

US: The California State Senate has voted in favour of a bill to implement the US’s most advanced statutory framework for cement industry decarbonisation by 74 votes to two. The statute provides for the implementation of lifecycle CO₂ emissions reporting for cement produced in the state at an estimated cost of US$220,000/yr. The California Air Resources Board will then implement a ‘programme developed as a result of identified strategies’ at an ‘unknown but significant cost.’ The aim of the strategy will be to facilitate a 40% reduction in cement production’s CO₂ emissions between 2019 and 2030 and the attainment of net zero cement production by 2045.

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.”
