US: Argos USA has announced the upcoming transition of its Roberta, Alabama, cement plant to Portland limestone cement (PLC) Type IL production. By mid-2022, the company plans to produce 100% PLC at the 1.7Mt/yr plant. Its Durham, Statesville and Wilmington cement terminals in North Carolina will also transition to the exclusive distribution of PLC. The Roberta plant will directly serve customers in Alabama, Florida, Georgia and Mississippi.

Argos USA has also launched PLC production at its Harleyville, South Carolina, Newberry, Florida, and Martinsburg, West Virginia, cement plants. It aims to begin producing PLC at all of its cement plants nationally by 2024.

CEO Bill Wagner said "We are excited to announce the transition of the Roberta plant to 100% (PLC) Type IL. With this transition, we continue to support our customers and the industry on its road to lower greenhouse gas emissions. With PLC, we are supplying a more environmentally friendly building solution for our customers, engineered to deliver an outstanding quality and performance while lowering our carbon footprint.”

Mexico: Cemex recorded consolidated net sales of US$14.5bn in 2021, up by 14% year-on-year. Sales rose by 10% to US$4.83bn in Europe, Middle East, Africa and Asia, by 9% to US$4.36bn in the US, by 23% to US$3.47bn in Mexico and by 16% to US$1.57bn in South, Central America and the Caribbean.

CEO Fernando González said “We are very pleased to report exceptional financial and strategic performance during 2021, despite the unprecedented challenges from Covid-19 and cost inflation.” He continued “In 2021, under our Future in Action programme, we accelerated our climate action ambition, establishing more aggressive 2030 decarbonisation goals as well as a detailed plant-by-plant roadmap to reach the targets. With our enhanced roadmap in place, we achieved our lowest carbon emission level on record and our largest annual year-on-year decline. And we pushed the boundaries on innovation, introducing new sustainable products and developing breakthrough decarbonisation technologies. Our performance gives me great confidence that we can reach not only our 2030 climate goal but also our Net Zero ambition.”

Pakistan: Power Cement has received the International Standards Organisation (ISO)’s ISO 50001:2018 certification for the energy performance of its management systems.

The producer said “We are on a never-ending quest to improve the environment for future generations by promoting the usage of sustainable energy.”

Colombia: Cemex Colombia has recorded accumulated sales of 500,000m3 of its Vertua reduced-CO₂ concrete. It aims to achieve net zero CO₂ emissions by 2050.

President Alejandro Ramírez said “Our Vertua concrete sales volume is excellent news for the country. It demonstrates that a sustainable vision of construction is being consolidated in Colombia, conscious of its decisive contribution to global climate action.”

Saudi Arabia: Qanbar Ready Mix has run its first trial mix of concrete using Canada-based CarbonCure’s CO2 utilisation technology. The Eastern Province-based ready-mixed concrete producer conducted a full-scale plant trial in late December 2021 in Ras Al Khair Industrial City, according to Gulf Construction. Employees, customers from Saudi Aramco and engineers were present at the event. Concrete supplied from Qanbar Ready Mix’s batching plants will be used to supply projects at the King Salman International Complex for Maritime Industries and Services.

Mexico: Holcim Mexico has replaced 11% of its concrete truck fleet with 61 new natural gas and Euro V diesel-fuelled Sinotruk vehicles worth US$6.2m. The company says that some of the trucks run on 100% natural gas, reducing both their CO₂ and particulate emissions by 25%. Parent company Holcim hopes eventually to roll out Sinotruk vehicles throughout operations in its Latin American region. Each truck has an 8m3-greater capacity than Holcim Mexico’s previous models, and also generates less noise.

Spain: Cemex’s Mósteles clinker pilot batch production unit at IMDEA Energy Institute in Madrid Autonomous Community has produced its first batch of solar-heated clinker. The unit uses Switzerland-based Synhelion solar radiation technology. The technology uses a solar receiver and gaseous heat transfer fluid to heat raw materials.

Cemex chief executive officer Fernando Gonzalez said “The production of the first solar clinker is an exciting milestone for this transformational technology. It is proof of our commitment to deliver tangible outcomes through innovation to achieve our goal of delivering only net-zero CO₂ concrete by 2050.” He concluded “Cemex is building a better future, and that future must be sustainable.”

India: Dalmia Cement (Bharat) has commissioned a 14.7MW solar power plant at its 1.3Mt/yr Kapilas grinding plant in Odisha. The producer says that the new power plant multiplies its total solar power capacity in Cuttack District by six to 17.1MW from 2.4MW.

The company said "Furthering Dalmia Cement (Bharat)'s sustainability goal of becoming carbon negative by 2040, this initiative will enhance the plant's energy efficiencies."

Japan: Sumitomo Osaka Cement started using an internal carbon pricing system for capital investments from January 2022. It is intended to create economic incentives for emission reductions and promote low-carbon investment. The starting price will be around Euro39/t of CO₂. The measure follows the company’s introduction of its 2050 carbon neutral goals and policies in late 2020.

Italy: Holcim has signed a collaboration agreement with energy company Eni for the development of ENI’s magnesium silicate-based carbon utilisation technology. The reaction of the magnesium silicate with captured CO₂ emissions yields a product which Holcim hopes to use in its cement production.

Holcim Innovation Center head Edelio Bermejo said “Reaching net zero in cement manufacturing will require the deployment of carbon capture, utilisation and storage technologies at scale. ENI’s solution is very promising, and we are happy to explore its potential as it could take us all one step further on our decarbonisation journey.”
