US: Keystone Cement has sought permissions to transport hazardous materials by rail to its Bath cement plant in Pennsylvania. The Express-Times newspaper has reported that the producer plans to build a six-tank farm and a railcar unloading facility at the plant, scheduled for commissioning in early 2026, to receive the materials. The Bath plant currently receives 10 – 15 tanker trucks of hazardous material daily.

Keystone Cement said "Transporting the hazardous wastes to site by the existing regional and local rail system would reduce the number of tanker trucks on the roads."

US: Colorado-based energy company NovoHydrogen plans to establish a hydrogen production facility at the Ash Grove Cement plant near Durkee, Oregon. Funded by the 2021 federal Bipartisan Infrastructure Act, the plant aims to start producing hydrogen fuel by 2028, according to CEO and founder Matt McMonagle. The hydrogen produced would be stored at the plant to be used to fuel trucks and other vehicles on-site, as well as potentially being used to power the plant. The construction of the plant will reportedly create 50 jobs.

Phillip Teintze, manager at the Durkee plant, said "The Ash Grove Cement Durkee plant is active in many opportunities to decarbonise our industry. Solutions for low carbon cement manufacturing are significantly challenging in terms of processes and expense. The Durkee plant is excited to see the development of NovoHydrogen’s efforts with the Department of Energy’s Pacific Northwest Hydrogen Hub. As hydrogen becomes environmentally and economically viable, we believe our facility could act as a distribution site, and potentially utilise hydrogen as a fuel to displace traditional fossil fuels.”

US: National Cement is upgrading its Lebec cement plant in California to make it carbon neutral. The upgrade involves a transition to limestone calcined clay cement (LC3) production. The producer will also substitute fossil fuels with locally-sourced biomass, including pistachio shells, in cement production. Lastly, a carbon capture installation will remove 950,000t/yr of CO₂ from the plant’s flue gases.

US: AMSCO Wear Products has announced its acquisition of wear parts supplier Global Partners Alliance. Following the deal, AMSCO Wear Products will also become the exclusive sales agent for Germany-based Stahlwerke Bochum, which supplies equipment including heat-treated alloy hammers, in North America.

AMSCO Wear Products vice president Sharon Morris said "We've always been committed to offering our customers the best wear-resistant castings for metals recycling, surface mining and waste-to-energy industries. When the opportunity to purchase Global Wear Products and partner directly with Stahlwerke Bochum came up, we were eager to work together. Knowing they had a great product and seeing how our values aligned, it was an easy decision.”

US: Summit Materials has entered into a memorandum of understanding (MOU) with hydrogen producer PCC Hydrogen (PCCH2). The MOU establishes an alliance to develop a fuel replacement strategy for Summit Materials’ cement production. PCCH2 will build a hydrogen plant to supply green hydrogen at a cement plant belonging to Summit Materials subsidiary Continental Cement.

Continental Cement president David Loomes said "Continental Cement has a longstanding commitment to environmental stewardship, seeking out opportunities to develop innovative practices and differentiated solutions to build a better tomorrow. Our company has signed on to the Portland Cement Association (PCA)'s Roadmap to Carbon Neutrality, with a goal of achieving carbon neutrality across the value chain by 2050. By coupling PCCH2's hydrogen production process with our cement manufacturing know-how, we are taking a bold stride towards achieving that goal, while continuing the push to cost-effective decarbonisation of cement manufacturing."

US: Holcim US has inaugurated a waste tyre processing plant at its Alpena cement plant in Michigan. The facility will process 22,000t/yr of tyres into refuse-derived fuel (RDF) for use at the cement plant. Holcim US partner Geocycle will collect, pre-process and deliver the tyres to the new facility.

Holcim US’ North regional senior vice president of manufacturing Michael Nixon said "Holcim has invested more than US$100m in eco-friendly technologies at the Alpena plant in the past 15 years. The tyre-derived fuel facility is another strong demonstration of our commitment to reducing emissions."

US: Continental Cement has ordered a Fuelflex Pyrolyzer alternative fuels combustion system from Denmark-based FLSmidth for installation at its Davenport plant in Buffalo, Iowa. The supplier says that its product offers a lower capital expenditure compared to competing systems, can control NOx emissions without the need for ammonia water and can be installed without a long shutdown period. This is the first commercial installation of the Fuelflex Pyrolyzer system following a pre-commercial installation at the Mannok cement plant in Northern Ireland, UK, in 2022.

David Loomes, the president of Continental Cement, said “We’re very excited about what the Fuelflex Pyrolyzer will do for our process.” He added, “We’re planning to achieve 55% fossil fuel replacement across the plant, utilising non-hazardous waste that would otherwise go to landfill or incinerators. The economic and environmental benefits of this technology are very significant and a key element of executing our carbon reduction commitment.” Continental Cement, a subsidiary of Summit Materials, has been incorporating waste materials as fuels for more than 30 years.

Jens Jonas Skov Larsen, Head of Capital Sales at FLSmidth, said “Mannok has called the Fuelflex Pyrolyzer a game-changer for the cement industry.” He continued, “This system effectively rearranges the order of the combustion process to make use of hot preheater meal, which is the heat source for the waste fuel pyrolysis. It’s a more efficient way of burning alternative fuels and it comes with a host of benefits, including reduced emissions and a more stable process.”

The installation at Davenport cement plant is expected to start operation in 2024. The full commercial launch for the system is scheduled by 2025. No value for the order has been disclosed.

US: Heidelberg Materials subsidiary Mason City Cement plans to invest US$4 - 5m in upgrades to its kiln line by 2026. Upon completion, the work will enable the plant to achieve an alternative fuel (AF) substitution rate of 50%.

Heidelberg Materials' North America regional vice president of government affairs and communications David Perkins said "We want to be proactive as a company and really try to lower our carbon footprint and energy intensity, while recognising we have to be competitive." He added "We're a long-term industry on the cement side because of the investment that's required to produce it."

US: National Cement Company of Alabama has reported that the new kiln line at its Ragland cement plant will reduce the plant’s CO₂ emissions by 40%. Its energy consumption will also fall by 30% as a result of the upgrade. The new line includes a 78m-high homogenisation silo, vertical crusher, five-stage preheater and automated clay storage system. AF used in the kiln will include waste tyres, woodchip and sawdust. The new kiln will help in the Ragland cement plant’s transition to 100% Portland limestone cement (PLC) production by 2023, further diminishing its carbon footprint.

Vicat CEO Guy Sidos said "Our ambition is to use AF in all our cement plants around the world. In addition to eliminating fossil fuel energy and replacing it with recycled regional waste, our investments contribute directly to local development. We are proud of the modernisation and transformation of our Ragland site, which was our very first acquisition outside France in 1974."

US: Vicat subsidiary National Cement Company of Alabama inaugurated its new US$300m production line at its Ragland cement plant on 21 July 2022. Local press has reported that the line includes a new rotary kiln, equipped for alternative fuel (AF) use.

President Spencer Weitman said “This puts us into the next 40 or 50 years. And it’s prolonged the life of the plant to move us forward into the next entry hopefully.”
