Mexico: Grupo Cementos de Chihuahua’s (GCC) sales fell in the first quarter of 2019 due to lower cement and concrete volumes in the US. Sales volumes rose in Mexico and the group described a ‘favourable pricing environment’ in both markets. Its net sales dropped by 1.9% year-on-year to US$163m from US$167m. Cement sales volumes fell by 7.3% in the US but they rose by 3.8% in Mexico. Earnings before interest, taxation, deprecation and amortisation (EBITDA) fell by 16% to US$38.3m from US$45.6m.

“The US operations slowed, with severe inclement weather continuing into the first quarter. However, there is a strong backlog and we are picking up the pace as the weather conditions improve,” said Enrique Escalante, GCC’s chief executive officer (CEO). He added that Chihuahua in Mexico continued to perform well driven by mining shipments, industrial maquiladora plants and warehouse construction and middle-income housing starts.

US: Eagle Materials are started a strategic review of its portfolio of businesses including heavy materials, light materials, and oil and gas proppants.

US: Lehigh Cement and Argos USA have agreed to pay a US$1.5m fine for alleged Clean Air Act violations at the Martinsburg cement plant in West Virginia. Argos has owned the plant since December 2016 and Lehigh Cement was the previous owner. The violations occurred from 2013 to 2016. Neither Lehigh Cement nor Argos USA admitted liability for the alleged violations as part of the settlement.

The Environmental Protection Agency (EPA) cited the companies for various Clean Air Act violations based on responses to EPA information requests and data collected and reported under the plant’s permit. These included exceeding particulate matter emissions, non-compliance with opacity testing, failing to comply with requirements for operating a kiln with dioxin/furan emission limits, failing to perform required stack testing on a kiln’s exhaust in a timely manner and other violations.

US: Illinois State University has been awarded a US$15,000 grant by the Environmental Protection Agency (EPA) to research the use of recycled glass as a substitute for Ordinary Portland Cement and fly ash in controlled low-strength material (CLSM). CLSM, also called flowable fill, is a cement-based construction material commonly used for backfilling trenches or other excavations, as well as soil-stabilisation. It can be produced at any ready-mix concrete plant by mixing cement, fly ash, sand and water in the correct proportions.

Project lead Pranshoo Solanki said that preliminary results are promising, and show that required flow and strength can be met by replacing cement and fly ash with recycled glass powder.

The EPA grant is for phase one of the recycled glass project for research at the laboratory scale. Funding for phase two will then be sought to test the product in real-world trials.

US: US Concrete has appointed Ronnie Pruitt as its president and chief operating officer. Pruitt will continue to report to chairman and chief executive officer (CEO) William J Sandbrook and, in this expanded role, will take over many corporate functions that support the company's operational business units.

Prior to joining US Concrete, he served as Vice President of Martin Marietta Materials and as Vice President of Cement Production and Vice President of Sales and Marketing of Texas Industries (TXI).

US: Cemex USA has been awarded the 2019 Energy Star Partner of the Year by the Environment Protection Agency (EPA) for its efforts in energy management. It was presented with the award by the EPA and the US Department of Energy at a ceremony in Washington, DC.

“At Cemex, sustainability is key to our vision of building a better future, embedded in our core business strategy and day-to-day operations,” said Cemex USA President Ignacio Madridejos. “We strive to conserve energy where possible with energy management initiatives, and many of our operations have received repeated recognition for their efforts. Cemex is also incorporating the use of more alternative fuels.”

Colombia: Cemex Colombia has reached a deal with the Attorney General allowing it to operate its Maceo cement plant in Antioquia. Under the terms of the government-brokered agreement Cemex will lease the land from CI Calizas y Minerales for around US$15,000/yr, according to the El Espectador newspaper. The lease has a duration of 21 years and this can be extended by another 10 years.

In 2016 Cemex fired several senior staff members in relation to the Maceo project and its subsidiary’s chief executive resigned. This followed an internal audit and investigation into payments worth around US$20.5m made to a non-governmental third party in connection with the acquisition of the land, mining rights and benefits of the tax free zone for the project. The US Department of Justice is also investigating the project.

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.
