LafargeHolcim US to convert Midlothian plant to Portland Limestone Cement production
15 September 2021US: LafargeHolcim US says that the integrated 2Mt/yr Midlothian plant in Texas will become the first cement plant in the country to fully convert to Portland Limestone Cement (PLC) production. The unit will switch to producing the company’s OneCem product, a blended cement manufactured with up to 15% of finely ground limestone. The move is intended to help LafargeHolcim US and its customers meet sustainable construction goals and lower carbon emissions.
“This is an important, but not unique, step for us. We were the first to produce OneCem, a PLC product, in one of the fastest-growing metro areas in the country, and fuel our industry’s step towards a zero carbon future,” said Patrick Cleary, senior vice president of sales, LafargeHolcim US Cement.
The company is promoting OneCem as an alternative to Ordinary Portland Cement in terms of concrete workability, set time, durability and strength development. It can be incorporated into a broad spectrum of applications that will support foundational structures. The product is available in the Western and Southern regions of the US and the company plans to ‘rapidly’ expand production.

Sustainable Energy Solutions partners with FLSmidth for Cryogenic Carbon Capture system adaptation and commercialisation
10 September 2021US/Denmark: Chart Industries subsidiary Sustainable Energy Solutions has chosen FLSmidth to help adapt and commercialise its Cryogenic Carbon Capture carbon capture and storage (CCS) system for the global cement industry. The system captures and stores CO2 from flue gas as a liquid. FLSmidth says that it will use its global reach and process knowledge to accelerate the commercialisation of Cryogenic Carbon Capture and optimise its design for cement plants. It believes the technology can cut 90% of process CO2 emissions at half the cost and energy consumption of current CCS processes.
FLSmidth cement president Carsten Riisberg Lund said “The cement industry is pursuing all options to reduce its environmental footprint, and CCS is a necessary technology to achieve this goal. Through this agreement with Chart, we lay the foundation for the scale-up and deployment of Cryogenic Carbon Capture technology with our customers. The technology developed by Chart is expected to become the most competitive at scale.” He added “This agreement is a significant leap forward in our joint efforts to enable our customers to reduce their environmental footprint.”
