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. The group’s operating earnings before interest, taxation, depreciation and amortisation (EBITDA) also rose, by 18% to US$2.86bn.

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.”

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.”

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.”

UK: Cemex UK has launched ReadyBlock Zero, a zero carbon concrete block, on the UK market. The product joins the company’s Vertua reduced-CO₂ product range. Cemex UK achieved zero carbon production by means of offsetting. It said that ReadyBlock Zero will help builders to meet the UK’s government’s Future Homes Standard, which requires a 75 – 80% CO₂ emissions reduction in all newly built homes.

Cemex’s Europe regional urbanisation solutions director of asphalt, paving and building products Carl Platt said “We have developed the UK’s first carbon neutral concrete block to help housebuilders get ahead of the game when it comes to building low carbon homes that meet and exceed government guidelines and changes to building regulations. We want to make life easier for housebuilders to make simple sustainable choices that make large scale impacts on the often complex road to net zero. Concrete blocks are the most common structural component in the construction of UK homes, so by switching to zero carbon blocks, ReadyBlock Zero presents a huge opportunity for housebuilders to make significant carbon reductions.”

US: LafargeHolcim US has announced the successful transition of two further plants to Portland limestone cement production. The company’s 4.5Mt/yr Ste. Genevieve, Missouri, cement plant and 2.4Mt/yr Alpena, Michigan, plant have begun exclusively producing its OneCem reduced-CO2 Portland limestone cement (PLC).

LafargeHolcim US’ manufacturing North vice president Michael Nixon said "LafargeHolcim is fully engaged in making carbon reduction an urgent priority and 100% dedicated to leading the market transformation needed for climate stability." He added "To achieve net-zero commitments by midcentury, we must start now in accelerating the adoption of low-carbon building solutions to mitigate the impacts of climate change."

LafargeHolcim US successfully transitioned its Midlothian, Texas, cement plant to PLC production in 2021.

Costa Rica: Société Générale de Surveillance has awarded Holcim Costa Rica its Positive Packaging certificate for 100% packaging energy recovery in 2021. The company offset the 1500t carbon footprint of its packaging production for the year by sorting and co-processing 14,000t of paper as fuel. It sourced the paper from its customer cement bag return scheme and through municipal recycling services run by fellow Holcim subsidiary Geocycle Costa Rica.

Holcim Costa Rica sustainability coordinator Catalina Mora said “Waste management is a global challenge, so this project has a direct impact on our contribution as a company to the vision of sustainability for the country.”

UK: Building materials group Ibstock has announced its commitment to achieving a 40% CO₂ emissions reduction by 2030 and carbon neutrality by 2040. The commitment covers scope 1 and 2 emissions, building on the company’s existing sustainability roadmap commitments to create a framework of targets and critical milestones. Ibstock says that these will include investment in more efficient production processes and in high quality environmental projects to offset residual carbon. Additionally, it plans to develop a strategy to reduce indirect scope 3 CO₂ emissions in 2022. It will publish full details of all targets in its 2021 full-year results in March 2022.

During 2021, Ibstock invested Euro138m in the construction of two net zero facilities in West Midlands and West Yorkshire and procured 100% of its electricity from renewable sources. Ibstock is the parent company of Ibstock Concrete, which produces concrete roofing, walling, flooring and lintels at 14 sites across the UK.

South Korea: Researchers at Incheon National University have discovered an optimal conductive carbon fibre volume for cement-based conductive composites for use in net-zero energy buildings. The team reported that a 1% conductive carbon fibre content facilitates maximum energy generation from the movements of occupants and the weather against floors and walls. It also enables the storage of electricity at safe voltages. The product is based on triboelectric nanogenerator (TENG) technology.

The team published its results in the journal Nano Energy in November 2021.

Germany: Cemex Zement has partnered with sustainable technology supplier Orcan Energy for the establishment of a waste heat recovery (WHR) plant at its Rüdersdorf, Brandenburg, cement plant. Orcan Energy will supply six generator modules for the installation. When commissioned in mid-2022, the WHR plant will cover part of the plant’s energy consumption. The German Federal Ministry for Economic Affairs and Energy contributed 50% of funds for the project.

Europe, Middle East, Africa & Asia regional president Sergio Menendez said “Efforts to achieve carbon neutrality at our Rüdersdorf cement plant by 2030 continue apace, and this project to install a WHR system is the latest significant milestone in our journey. It further demonstrates the value of forming expert alliances to investigate and then implement innovative technologies that will ensure the decarbonisation of our operation.”

France: Vicat has reiterated its CO₂ emissions reduction target of 55% between 1990 and 2030 and reaffirmed its 2050 carbon neutrality commitment. The company says that its will invest Euro800m in transitioning to lower-CO₂ cement production between 2021 and 2030 in order to meet the 2030 target. It said that eight US and European cement plants with ‘limited decarbonisation standards’ currently generate 67% of its earnings before interest, taxation depreciation and amortisation (EBITDA).
