US: Eagle Materials’ consolidated sales rose by 13% year-on-year to US$1.45bn in the third quarter of the 2022 financial year from US$1.28bn in the corresponding quarter of the 2021 financial year. Its sales of cement rose by 12% year-on-year to US$261m, while its earnings from the segment were US$79.8m, up by 13%. Cement volumes totalled 2Mt, up by 7% from third-quarter 2021 financial year levels.
Chief executive officer and president Michael Haack said that the results reflected both continued strength in US construction activity and excellent execution by Eagle Materials as Covid-19-related supply chain challenges continued. He said “We continue to see positive demand trends across our geographic footprint, driven by increased residential construction activity and expanded infrastructure investment. These trends should support growing construction activity and contribute to attractive pricing across our heavy and light materials businesses. We enter the last quarter of our fiscal year in a position of strength, with an excellent balance sheet enabling us to continue to execute on our core strategies.”
Haack added “I’m also proud to share that, during the first nine months of our fiscal year, we achieved the best safety performance in our history, demonstrating our deep commitment to our people and their wellbeing. During the quarter, we also continued to make strides towards our environmental stewardship goals. We are now producing and selling our eco-friendly Portland limestone cement (PLC) from four Eagle cement facilities.”

PCA announces Energy and Environment Awards 2021 winners
09 December 2021US: The Portland Cement Association (PCA) has announced the winners of its Energy and Environment Awards 2021. The awards recognise cement plants’ outstanding environmental and social efforts beyond what is required.
CalPortland’s Mojave plant in California won the Energy Efficiency award for an efficiency-increasing upgrade to its vertical roller mill, which included the introduction of a bottom hopper cone on each of its cyclones and a replacement of its mill fan housing. Argos USA’s Calera plant in Alabama won the Land Stewardship award for its conversion an 8.5ha lime kiln dust stockpile into grassland. The area now forms a vibrant ecosystem including wetland habitats. The producer also installed ponds with the additional purpose of stormwater management. Titan America’s Pennsuco plant in Florida won the Overall Environmental Excellence award for its conversion of the plant’s kiln to natural gas from coal use. The upgrade has also enabled the plant to begin to substitute alternative fuel (AF) in the kiln. The Pennsuco plant plans to produce 100% Portland limestone cement (PLC) by ‘as early as 2023.’
Other awards went to Roanoke Cement’s Troutville, Virginia, plant in the Environmental Performance category and to Cemex USA’s Victorville, California, plant in the Outreach category.
PCA President and CEO Michael Ireland said “The US’s cement manufacturers continue to focus on researching and developing new and innovative ways to reduce their environmental footprint. These accomplishments and industry commitment to carbon neutrality across the entire value chain demonstrate PCA members’ dedication to energy efficiency and a more sustainable future.”
