US: Cemex has increased production of Portland limestone cement (PLC) at its Lyons plant in Colorado. PLC is expected to become the plant’s primary product by the summer of 2022. The blended cement has been produced at the site for over 15 years. However, Cemex says it is growing production to meet the company’s carbon reduction goals and meet increased demand for lower carbon materials.
Cemex USA has also increased PLC production at its plants in Brooksville, Florida, and Demopolis, Alabama. The start of PLC production or further increases is planned for other cement plants later in 2022.

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.
Bolivia/Mexico/US: The US District Court of Colorado has confirmed compensation of US$36.1m awarded to Bolivian investment company Compania de Inversiones Mercantiles (CIMSA) from Mexico’s Grupo Cementos de Chihuahua (GCC). The arbitration follows a dispute that started in 2011 between CIMSA and GCC about the sales of shares in the Sociedad Boliviana de Cemento (SOBOCE) to Consorcio Cemento del Sur de Perú.
GCC said that it will continue to dispute the ruling and that it would continue to fight the legal case in Bolivia. In 2015 local courts in Bolivia overturned damages imposed by the Inter-American Commercial Arbitration Commission (CIAC) upon GCC.
