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."

National Cement Company of Alabama’s Ragland cement plant upgrade to reduce CO2 emissions by 40%

25 July 2022

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."

Veolia North America to shred GE Renewables’ used wind turbine blades for cement materials and fuel

15 December 2020

US: Veolia North America (VNA) has signed a contract for the supply of used blades from onshore wind turbines from GE Renewables. The waste management company will process the blades to produce shredded composite materials for use in cement production, both as replacement for war materials such as sand and clay and as an alternative fuel. As a part of the agreement, blades that have been removed from turbines will be shredded at VNA’s processing facility in Missouri and then used in cement plants across the US. On average, nearly 90% of the blade material, by weight, will be reused as a repurposed engineered material for cement production.

Environmental solutions and services chief operating officer (COO) Bob Cappadona said, "By adding wind turbine blades — which are primarily made of fibreglass — to replace raw materials for cement manufacturing, we are reducing the amount of coal, sand and minerals that are needed to produce the cement.” GE Renewables and sustainability consultant Quantis said that the use of turbine blades in cement production would reduce net CO2 emissions by up to 27% and water consumption by up to 13%.

Regional law change puts a stop to Lafarge Ravena alternative fuel plans in the US

14 September 2020

US: The legislative body of Albany County, New York, has enacted a law ending the establishment of new waste burning facilities. The Times Union newspaper has named LafargeHolcim subsidiary Lafarge North America’s 2.0Mt/yr Ravena cement plant amongst facilities affected. The legislature came to its decision following public outcry after Lafarge North America announced its plans to renew its licence to burn up to 4.8Mt/yr of tyres in January 2019.

Legislator William Reinhardt said, “While most of the attention had been focused on the potential impacts of the law on facilities like Norlite and LaFarge, the real intended point of the legislation is longer term. We want clean air not only today but for the foreseeable future.”
