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).

World: The governments of Canada, Germany, India, the UAE and the UK have signed a commitment to support the development of markets for low-carbon cement and concrete in their countries. The governments will create market incentives for purchasers, review and update product standards to allow low-carbon materials to be used in all safe settings and promote their use through their public sector tendering rules.

World Cement Association (WCA) chief executive officer Ian Riley said “I’m delighted to see that governments are heeding our call for urgent action to accelerate decarbonisation of the cement industry around the world, and we look forward to hearing more details from the UK, India, Germany, Canada and UAE on the steps they will take.” He added “This commitment marks a hugely significant shift in mindset that we hope will be followed by other countries in the months ahead. When it comes to hard-to-abate industries like cement, it is vital to work together with governments to create the conditions in which we can get to net zero and beyond, as quickly as possible. We cannot do this alone in time.”

India: UltraTech Cement has committed to the Global Cement and Concrete Association’s 2050 roadmap for net zero concrete. It says that in realising the commitment, it hope to contribute to building the sustainable world of tomorrow. The Roadmap also includes a sectoral commitment to cut CO₂ emissions by a further 25% by 2030.

Mexico: Cemex’s consolidated sales in the first nine months of 2021 were US$11bn, up by 5% year-on-year from US$9.4bn in the corresponding period of 2020. Its cement sales rose by 10% to 51.1Mt from 46.2Mt, while its ready-mix concrete volumes increased by 7% to 36.8Mm3 from 34Mm3. Its operating earnings before interest, taxation, depreciation and amortisation (EBITDA) totalled US$2.24bn, up by 24% from US$1.81bn. Its gross profit was US$3.63bn, up by 18% from US$3.07bn. During the period, the group reduced its debt by 33% to US$8.98bn from US$13.3bn.

Cement volumes grew in all regions in every quarter of the year except the third, when they fell by 3% in Mexico and remained level year-on-year in Europe, the Middle East, Africa and Asia. The quarter brought an end to five consecutive quarters of double-digit year-on-year growth in bagged cement sales in Mexico. Mexican bulk cement sales meanwhile ‘accelerated in line with the formal sector recovery.’ The sharpest nine-month cement volumes growth was in South, Central America and the Caribbean, where sales rose by 19% year-on-year, followed by Mexico, with a rise of 12%.

CEO Fernando González said “We are pleased to report strong top-line growth, reflecting continued growth in demand for our products, coupled with an acceleration in pricing momentum. We are confident that our pricing strategy will more than compensate for the sudden runup in input cost inflation we have experienced.” He added “We remain optimistic regarding outlook, as most of our markets are operating at high capacity utilisation and sustainable midcycle levels that will be supported by monetary and fiscal stimulus, while others are just beginning an upcycle. Regarding our Future in Action initiative, we continue to advance on our climate action goals. During the quarter, we received validation from SBTi of our 2030 decarbonisation roadmap and joined the Race to Zero initiative. Our climate action agenda is a fundamental element of our medium-term strategy not only because it creates value for stakeholders, but because it is the right thing to do for future generations.”
