US: The US Department of Energy (DOE) has awarded funding for two Leilac projects to conduct preliminary front-end engineering design (pre-FEED) studies, subject to final negotiations.

A project at Roanoke Cement Company in Virginia, led by Titan Group in partnership with Leilac, Amazon and Virginia Tech, received US$1.49m. It aims to capture over 500,000t/yr of CO₂ from cement Scope 1 emissions using Leilac’s technology.

A project at Mississippi Lime Company in St Louis, Missouri, in partnership with Leilac, Industrial Ally and Nuada, received US$1.5m. It seeks to achieve net-zero lime manufacturing by integrating Leilac’s CO₂ capture technology with Nuada’s carbon capture system for combustion emissions.

Calix CEO Phil Hodgson said “We look forward to concluding the grant agreements and developing these exciting projects that have the potential to demonstrate industry-leading solutions to produce both low-carbon cement and lime at commercial scale.”

The US Department of Energy (DOE) announced a US$1.6bn investment in the cement sector this week. The funding was part of a total of US$6bn for 33 projects in over 20 states to decarbonise energy-intensive industries also including chemicals and refining, iron and steel, aluminium and metals, food and beverages, glass, process heat applications and pulp and paper. The DOE was keen to link the money to “the President’s Bipartisan Infrastructure Law and Inflation Reduction Act.” Politics is never far away it seems! The projects are part of the Industrial Demonstrations Program, managed by DOE’s Office of Clean Energy Demonstrations (OCED).

Table 1 above shows the main approaches each of the projects aim to use. The two most expensive ones involve carbon capture and sequestration (CCS) at Heidelberg Materials US’ Mitchell cement plant in Indiana and National Cement’s Lebec plant in California respectively. In a complimentary press release Chris Ward, the CEO of Heidelberg Materials North America, said “This substantial federal funding investment will help create the first full-scale deployment of carbon capture and storage on a cement plant in the US.” The proposed CCS unit at the plant will capture around 2Mt/yr of CO₂ from 2030. If Ward’s forecast is accurate (and no one beats them to it), then Heidelberg Materials will likely have set up the first full-scale CCS units at cement plants in both North America and Europe. This will be a significant achievement. The National Cement project, by contrast, is a mixed bag of approaches to decarbonising cement production that follows the multi-lever approach advocated for in many of the industry net-zero roadmaps. It intends to use agricultural by-products such as pistachio shells, as alternatives fuels to lower the fuel-based emissions, calcined clay to lower the clinker factor and CCS to capture the remaining 950,000t/yr of CO₂ emissions.

The other projects either involve using calcined clay or substituting limestone with calcium silicate. The Summit Materials proposal is noteworthy because it aims to build four clay calcination units in locations in Maryland, Georgia and Texas. None of these appear to be near Summit’s (or Cementos Argos’) cement plants. This suggests that the company may be intending to use calcined clay in ready-mixed concrete production. The Roanoke Cement Company calcined clay project will be baseEuropead at its cement plant in Troutville, Virginia.

The remaining two grant recipients, Brimstone and Sublime Systems, will both test the companies’ different methods of manufacturing cement by using calcium silicate instead of limestone. Brimstone’s method produces ordinary Portland cement (OPC) and supplementary cementitious materials (SCM). The company said in July 2023 that its OPC met the ASTM C150 standards. However, the company has released less information about its actual process. Sublime Systems’ uses an electrolysis approach to create its ASTM C1157-compliant cement. It calls this ‘ambient temperature electrochemical calcination.’

Investment on the same scale of the DOE has also been happening in Europe. In July 2023, for example, the European Commission announced an investment of Euro3.6bn in clean tech projects to be funded from the proceeds of the European Union emissions trading scheme (ETS). This was the third call for large-scale projects following previous announcements of recipients in 2021 and 2022. Euro1.6bn of the third call funding went towards cement and refining projects including five cement and lime projects in Belgium, Croatia, Germany and Greece. The money granted for each of these schemes was in the region of Euro115 - 235m.

Both the US and Europe are throwing serious finance at the cement industry to try and kickstart the various pathways towards net zero. They are also doing it in different ways, with the US aiming to boost its economy by onshoring sustainable industry, and Europe hoping to fund its approach via carbon taxation. Government-driven decarbonisation investment for cement in other large countries and regions around the world appears to be lagging behind the US and Europe but these may spring up as net zero targets are set, roadmaps drawn up and government policy formulated. These places could also benefit from watching what works and does not work elsewhere first. Back in the US and Europe the next tricky part of this process will be bridging the gap between government subsidy and commercial viability.

US: The US Department of Energy has selected four cement producers to receive funding under the Bipartisan Infrastructure Law and the Inflation Reduction Act.

Heidelberg Materials US secured up to US$500m for its planned 2Mt/yr carbon capture project at the Mitchell cement plant in Indiana. National Cement also received up to US$500m, for its Lebec Net Zero limestone calcined clay cement (LC3) project in California. Summit Materials received up to US$216m for a series of clay calcination projects in Georgia, Maryland and Texas. Lastly, Roanoke Cement will receive up to US$61.7m for an LC3 project at its Troutville cement plant in Virginia.  These projects also involve developing a training, education and certification consortium in the cement sector.

Portland Cement Association (PCA) president and CEO Mike Ireland said "This funding is a welcome acknowledgement from the government that America's cement manufacturers are taking ambitious and significant steps toward reaching carbon neutrality. This will move the needle closer to achieving what industry considers the 'heavyweight' of carbon solutions: carbon capture utilisation and storage (CCUS). Once established nationwide, CCUS will greatly accelerate cement manufacturers' charge toward net zero."

Senior vice president of government affairs Sean O'Neill added “From passage of the Bipartisan Energy Act of 2020 to securing funding through the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, today's announcement is another major milestone in the cement industry's decarbonisation efforts. The PCA is committed to continuing to work with policymakers to ensure the regulatory environment facilitates rather than impedes these and future investments.

US: Roanoke Cement, part of Titan America, has held a ground-breaking ceremony for an expansion at its Chesapeake Terminal near Norfolk in Virginia. Council members, other state and local officials and Roanoke Cement team members gathered to launch the project, to build a new US$40m storage dome. In response to increasing demand for low carbon cement, the storage dome at the terminal will provide an additional 70,000t of capacity, tripling the site’s existing storage volume. The Chesapeake Terminal will see expanded truck and rail capacity as well, and the improved terminal will enable the import and distribution of other raw materials needed to produce concrete.

"This important capital improvement is another investment in anticipation of increased construction material demand for infrastructure development and other projects," said Kevin Baird, president of Titan America's Mid-Atlantic Business Unit, which includes Roanoke Cement. "Expanded storage and marine terminal upgrades permit us to make low carbon cement available for construction needs all over the region."

The company expects the expanded facility to be completed by the end of 2023, in time for the region’s 2024 construction season.

US: Green Business Certification (GBC) has recognised Titan America subsidiary Roanoke Cement’s successful implementation of its zero waste policy at the 1.5Mt/yr Troutville, Virginia plant with a Total Resource Use and Efficiency (TRUE) Gold award. In 2019 the plant won the GBC’s TRUE Silver award. Roanoke Cement environmental engineer Lindsey Layman said, “In order to elevate our TRUE Zero Waste certification, we ramped up our zero waste policy to include, for example, physical audits of waste and improving recycling practices on-site. As a result, we have created a zero-waste culture and achieved an average of 98% overall diversion from landfill and incineration of solid non-hazardous wastes.”

US: Titan America subsidiary Roanoke Cement has settled on a fine of US$3640 with the Virginia Department of Environment Quality (DEQ) for the breach of emissions regulations after a kiln gas outlet at its 1.5Mt/yr Troutville plant in Botetourt County, Virginia, recorded an average temperature of 121°C over a nine-hour period on 26 June 2019. Virginia DEQ enforcer Marvin Booth said there was ‘no documented harm to public health or the environment’ resulting from the violation.

US: The Portland Cement Association (PCA) has announced the winners of the 2019 Energy and Environment (E&E) Awards. The awards recognised environmental and community relations projects that were completed in 2018 and were presented at the 3rd Annual Cement and Concrete Fly-In.

The CalPortland Mojave cement plant in California won the Energy Efficiency award for the installation of a new classifier system for its vertical roller mill that increased energy efficiency by reducing fan power requirements. The plant also installed a control system for the finish mill that will maximise performance and help reduce wear on equipment. The classifier installation reduced the finish mill energy intensity by 1.5 to 2.0kWh/t, and the control system reduced energy intensity by 13%. In 2018 22% of the electricity consumed by the plant came from on-site renewable wind energy generation. CalPortland has implemented significant energy efficiency measures and its energy management program has been recognised by the Environmental Protection Agency Energy Star program as the Energy Star Partner of the Year for 15 years in a row.

Roanoke Cement Company and Titan America’s Troutville plant in Virginia won the Environmental Performance award for being the first cement manufacturing plant in the US to receive ISO 50001 certification for energy management of all aspects of energy procurement, design and use. The plant reduced its total electrical consumption by 10% and fossil fuels use by more than 12%. The plant has also implemented an alternative fuels program as part of its certification for the True Zero Waste Program, administered by Green Business Certification and has received silver status achieving a 96% rate of waste divergence from landfills.

Lehigh Hanson’s Permanente cement plant at Cupertino in California won the Innovation award for the installation of a water treatment system reducing concentrations of metals, including selenium, to meet permit limits. Lehigh Hanson developed a treatment system that combined ultrafiltration and reverse osmosis (UF/RO) technology in conjunction with biological treatment technology to remove metals, including selenium and dissolved solids. This ensured applicable effluent limits were met while optimising treatment capacity and efficiency. This treatment system is the first of its kind in the cement industry ensuring that effluent limits are met while, at the same time, limiting the quantity of waste needed to be managed.

Buzzi Unicem USA’s Greencastle cement plant in Indiana won the Land Stewardship award for opening a 4km smooth packed stone trail in conjunction with the not-for-profit People Pathways organisation as Phase 2 of the Putnam Nature Trail. Buzzi Unicem USA staff and People Pathways used heavy equipment for rough clearing and grading of the overgrown former railroad bed and improved and expanded the physical trail. These areas were then landscaped with trees, native prairie vegetation plugs, interpretive signage, benches, birdhouses and other features. Additional nature trail enhancements include placement of wildlife monitoring cameras along the trail, installation of nesting boxes and interpretive signage, and maintenance of the recently completed restoration of native flora installed in 2017 and 2018.

Cemex’s Lyons cement plant in Colorado won the Outreach award for volunteering work by its staff at the Rocky Mountain National Park in Boulder, Colorado, performing campground improvement activities at Glacier Basin Campground by moving rocks and fallen timber and clearing existing fire pits of ash deposits. The plant then introduced a new community outreach initiative by hosting a Manufacturing Day event, providing local students tours of the quarry and plant to increase youth interest in pursuing a vocation in skilled trades. Additionally, the plant teamed up with the Celestial Seasonings B Strong Ride for cancer care and research for an event aimed at increasing safety awareness while fundraising for two local organizations and their efforts to fight cancer.
