US: Block-Lite plans to install a system to cure concrete blocks using direct air capture (DAC)-sourced CO₂ at its Flagstaff, Arizona, concrete block plant. The upgrade will implement CarbonBuilt’s low-CO₂ concrete production technology and AirCapture’s modular DAC technology, across five or six capture units. Direct air capture will thus remove 500 – 600t/yr of CO₂ from the atmosphere, while process changes will reduce CO₂ emissions from the Flagstaff plant by over 2000t/yr. The project has attracted fundraising from the 4 Corners Carbon Coalition (4CCC), with a goal of US$50,000. The Arizon Daily Sun newspaper has reported that Block-Lite plans to supply its first shipment of low-CO₂ blocks to a 50-home development by Habitat for Humanity in Flagstaff.

US: The Environmental Protection Agency (EPA) has announced that 10 cements plants have received its Energy Star certification in 2022 from a total of 86 manufacturing plants across all industries. The certification is awarded to the top 25% performers in energy efficiency in each sector. The EPA cited examples of how Titan America’s Troutville plant in Virginia and its Medley plant in Florida had converted production to Portland Limestone Cement (PLC), and achieved a 12% reduction in electricity use and an 18% reduction in CO2 emissions, respectively, thanks to improved energy management. It also mentioned Cemex’s Miami plant in Florida, which increased its energy performance in 2022 by modifying a finish mill, optimising the ball charge on the largest mill and identifying and correcting potential energy losses while also increasing the production of PLC.

Cement plants awarded the Energy Star certification in 2022 include: Drake Cement’s Paulden plant and Salt River Materials Group’ Clarkdale plant in Arizona; GCC’s Pueblo plant in Colorado, Cemex’s Miami plant and Titan America’s Medley plant in Florida; Argos USA’s Harleyville plant in South Carolina; GCC’s Rapid City plant in South Dakota; Buzzi Unicem USA’s Chattanooga plant in Tennessee; Titan America’s Troutville plant in Virginia; and Ash Grove Cement’s Seattle plant in Washington.

US: Bulk material handling equipment supplier MDG America says that it delivered four chain bucket elevators for Drake Cement's upgrade of its Paulden cement plant in Arizona. Drake Cement installed a new vertical mill grinding plant for cement, granulated blast furnace slag (GBFS) and raw materials grinding at the 0.7Mt/yr integrated plant. The supplier says that two of the elevators will work in a pair, conveying material from a feeder belt, while a third will convey it to the new mill. The fourth elevator will then collect the material for further grinding and metal discharge.

Drake cement secured approval to mine pozzolan for use in the Paulden's plants cement production at Bill Williams Mountain earlier in October 2022. As part of minimising the future mine's impacts, Drake Cement has offered to help the US Forestry Service to thin local woodland as part of local anti-fire management efforts.

Cemento Yura said it was considering expanding cement and lime production this week. The announcement, made in an interview to business newspaper Gestión, follows a strong second quarter for the subsidiary of Grupo Gloria with clinker production volumes jumping up by 36% year-on-year to 0.51Mt. Overall for the half-year its clinker and cement production rose by 12.8% year-on-year to 0.86Mt and 12.7% to 1.47Mt. The success was attributed to consistent demand from the domestic sector as well as various large-scale mining projects. Julio Cáceres, the commercial director for its Cement, Concrete and Lime Division in Peru, Chile and Bolivia, wouldn’t say where the company was considering heading next, other than that remarking that it was attentive to new markets.

As Cáceres’ job title implies Cemento Yura also operates cement plants outside of Peru. At home it runs one integrated plant in the south of the country near to Arequipa as well as a lime plant at Juliaca. Outside of Peru though it also runs two integrated plants and a grinding unit in Bolivia, via its Sociedad Boliviana de Cemento (SOBOCE) subsidiary, and two integrated plants in Ecuador, via its Union Cementera Nacional (UCEM) subsidiary. The company also has assorted concrete assets. The international aspect to Cemento Yura’s business is interesting given that the larger cement producers in Peru are dominant in different parts of the country with Cementos Pacasmayo in the north, UNACEM (Unión Andina de Cementos) in the centre around Lima and Cemento Yura in the south. Notably, UNACEM also runs a plant in Ecuador and one in Arizona, US. It is also worth mentioning that competition issues have been reported in the local market previously. In mid-2021 Peru’s competition authority, the National Institute of the Defense of Competition and Intellectual Property Protection (INDECOPI), investigated Cemento Yura.

Cemento Yura’s rise in clinker production in the second quarter of 2022 is worth considering because in a previous interview with the local press Humberto Nadal, the chief executive officer of Cementos Pacasmayo, said that importing clinker had become more expensive in 2021. Subsequently, the company started a US$70m upgrade at its Pacasmayo plant to increase its production capacity by 0.6Mt/yr. In its second quarter financial results for 2022 Cementos Pacasmayo directly credited a 27% increase in its earnings on higher operating profits arising from decreasing costs by using less imported clinker. Sure enough data from Association of Cement Producers (ASOCEM) shows that both cement and clinker imports started to fall in October 2021 and have mostly followed a downward trend since then. Clinker imports fell by 41% year-on-year to 0.66Mt from January to August 2022 compared to the same period in 2021.

Looking at the wider picture in Peru, cement production has stayed fairly consistent since 2014 at around 10Mt/yr. An upward trend probably started in 2019 but then the Covid-19 pandemic cut it off in the first half of 2022 before the market surged back in the second half of that year. 2021 was a good year with production peaking at 12.9Mt. So far the first eight months of 2022 have seen production rise by 5.3% year-on-year to 8.64Mt.

In summary, cement production is rising in Peru, importing clinker appears to have become more expensive for at least one of the producers and some of the larger local companies are investing in new production capacity, considering it or thinking about acquisitions elsewhere. Local clinker producers appear to be in a good place; clinker importers, or those reliant on it, not so much.

US: The Nevada Department of Transportation has approved the use of Portland limestone cement (PLC) for road construction and repairs. The department expects the move to reduce CO₂ emissions by 4000t/yr. It uses 45,000t/yr of cement in its projects. Local press has reported that transport contributed 35% of Nevada’s CO₂ emissions in 2022, making it the largest single source.

US: Drake Cement & Materials has inaugurated a new finish mill at its integrated plant at Paulden in Arizona. Chief executive officer Enrique Rozas and Ricardo Rizo Patron, the chairman of parent company Skanon Investments, attended the event. Drake Cement & Materials is a subsidiary of Peru-based UNACEM.

US: The state governments of Arizona, Maryland and Vermont have approved the use of Portland limestone cement (PLC) in public construction projects. The rule changes bring the total number of states in which PLC may be used in this way to 44.

The Portland Cement Association (PCA) has welcomed the decision. The association said "Widespread acceptance of PLC marks a significant step to reducing the carbon footprint of concrete construction and advancing the goals laid out in the PCA Roadmap to Carbon Neutrality."

US: The Environmental Protection Agency (EPA) has awarded its Energy Star certification to cement plants belonging to two Titan America subsidiaries. Titan Florida’s Pennsuco, Florida, cement plant has secured its 14th consecutive Energy Star, while Roanoke Cement’s Troutville, Virginia, cement has secured its 15th consecutive Energy Star.

Other cement plants to receive Energy Stars in 2022 included two Argos USA plants (Calera, Alabama, and Harleyville, South Carolina), two GCC plants (Pueblo, Colorado, and Rapid City, South Dakota), Buzzi Unicem’s Chattanooga, Tennessee, plant and three plants in Arizona: CalPortland’s Rillito plant, Drake Cement’s Paulden plant and Salt River Materials Group’s Clarkdale plant.

Mexico: Cemex says that it plans to restart Line 2 at its CPN cement plant in Sonora State. The line has a capacity of 0.8Mt/yr. Cemex will invest US$29m in restarting it, bringing its total recent investments in the CPN plant to US$44m. It previously invested US$15m in a restart of the plant’s 1Mt/yr Line 1 in 2021. When operational in mid-late 2022, Line 2 will join the existing line in supplying cement to Arizona, California and Nevada in the US.

Cemex USA president Jaime Muguiro said “Many cement customers in the western US have been impacted by tight supply constraints for several months, and at Cemex, we are proactively looking for opportunities to further alleviate those conditions and enrich customer experiences by enhancing how we operate while utilising our global reach.” He continued “Customers require more cement to keep pace with the region’s growth, and we want to ensure they have stable and steady access to the high-quality materials that are essential to meet their needs.”

US: Hanson Aggregates has purchased 577ha of land near Buckeye, Arizona. The Phoenix Business Journal newspaper has reported that the company will use the land to produce ready-mix concrete and rock products and. Martin Marietta Materials agreed to acquire Germany-based HeidelbergCement’s US West regional business, which included Hanson Aggregates, in May 2021 for US$2.3bn.
