Germany: The Federal Cartel Office has approved the takeover of Heinrich Teufel by Holcim Deutschland. The subsidiary of Switzerland-based Holcim said it had agreed to acquire the ready-mix concrete and aggregates in July 2021. The purchase is intended to increase the company’s presence in southern Germany.
Low carbon cements go global
28 July 2021Holcim has started to unify its low carbon cement product range this week with the launch of its ECOPlanet label globally. The products are already available in Germany, Romania, Canada, Switzerland, Spain, France and Italy. The plan is to extend this to 15 countries by the end of 2021 and then to double its ‘market presence’ by the end of 2022.
The headline news is that the range will include what Holcim says is the world’s first cement product with 20% recycled construction and demolition waste. This appears to be an improvement on the group’s Susteno cement products that use fine fractions from concrete and demolition waste. This product is currently sold in Switzerland where it is advertised as saving 10% of CO2 emissions compared to a standard cement product. Both Holcim and HeidelbergCement already sell concrete products that use the coarse waste from building demolition. Other than this, Holcim says that the range will also include cements that contain calcined clay. In June 2021 subsidiary Lafarge France announced that it would produce a cement product under the ECOPlanet banner using kaolin clay with its proprietary ProximA Tech process at its integrated La Malle cement plant in Bouc-Bel-Air.
We will have to wait and see how far Holcim goes in standardisng the range between different countries. Yet, judging from what the countries that are already selling ECOPlanet are doing, it looks like it will be a variety of blended cements. At present, for example, Holcim Germany offers four products in the ECOPlanet range. These are all slag cements, with three having effective CO2 reductions of up to 70% and the fourth, ECOPlanet Zero, reaching 100% through a carbon offsetting scheme in conjunction with MoorFutures. Holcim Italy also launched a product in the range called ECOPlanet Prime using calcined clay in June 2021.
Incidentally, LafargeHolcim US announced a research project this week with the US Army about using demolition waste. It’s going to start working with the US Army Corps of Engineers’ Engineer Research and Development Center and Geocycle to look at how construction and demolition materials from military installations can be used for energy recovery and mineral recycling. Group resources at Geocycle’s Holly Hill Research Center in South Carolina, US and Holcim’s Global Innovation Center in Lyon, France will be used in the scheme.
Other low carbon cement products are available of course. Holcim is far from alone in launching low CO2 cement and concrete products. Yet the use of worldwide brand names is different. Cemex is doing something similar with the global rollout of its Vertua concrete products. It first launched Vertua in France in 2018 before going global in 2020. Holcim started to launch ECOPact Concrete in 2019. Now, Holcim has gone further by doing the same thing with cement. Given how localised cement and concrete products are, it will be instructive to see how global branding for low carbon cementitious products helps these companies. For instance, who is the target audience? It could be eco-minded self-build customers or project specifiers or government departments or industry lobbyists. Or perhaps it is simply another marketing channel to reinforce the sector’s sustainable offerings.
The other point worth considering is when will the multinational cement producers start selling sustainable cements and concretes in less rich parts of the world? While Holcim was playing with blended cements and marketing this week, Dangote Cement said that it was ready to start commissioning its new 6Mt/yr integrated plant at Okpella, Edo State in Nigeria. Another 5Mt/yr plant is also on the way in the country from Madugu Cement. It has just signed a contract for China-based Sinoma International Engineering Company to build it. When Holcim and the other cement companies start selling low carbon cements in places like Nigeria then the rise of these products will be complete.

28 July 2021Mexico: GCC’s sales rose by 9.7% year-on-year to US$466m in the first half of 2021 from US$424m in the same period in 2020. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 15.3% to US$147m from US$127m. Cement sales volumes grew by 3.2% and 11.5% in the US and Mexico respectively. Concrete sales volumes fell by 21.1% in the US but grew by 22.8% in Mexico.
“Cement demand is stronger than pre-pandemic levels and construction activity is expected to remain robust throughout the year. Every kiln at GCC is up and running,” said Enrique Escalante, GCC’s chief executive officer.
France: Cemex France has supplied 40,000m3 to the site of the now completed Paris Duo Towers in Paris, Île-de-France. The company also provided construction waste removal services through its multimodal transport network. The producer said that the strong commitment of its technical teams ensured the success of the operation. It said that excellent communication between its various departments and the concrete production teams enabled ‘smooth and consistent’ concrete deliveries.
Cemex UK launches sustainability professional development course for concrete specifiers
22 July 2021UK: Mexico-based Cemex subsidiary Cemex UK has launched ‘Concrete – Focus on Sustainability,’ a Royal Institute of British Architects (RIBA) accredited continuing professional development (CPD) course for specifiers. The course tackles the key issues for accomplishing building projects’ sustainability goals when using concrete. It covers various industry initiatives and technologies designed to aid these goals.
National product support and CPD coordinator Mat Saunders said “The conversation around sustainability is currently at the forefront of the minds of everyone globally, and as an organisation we have a responsibility to contribute to that discourse in a positive manner. This is why we felt that educating industry professionals on what cement and concrete technology can do to help specifiers, clients and contractors meet their sustainability targets, while still using concrete to build safe, efficient, beautiful structures that we all live and work in, was paramount. Even at this early stage the course has been wildly popular, and we anticipate a significant uptake over the rest of 2021 and beyond.”
Germany: Former HeidelbergCement executive director Rainer Nobis’ Illustrated History of Cement and Concrete is now available in hardback online. The book traces the development of artificially produced building materials over 12,000 years, describing both the technical sequence of events and the political and economic environments in which they took place.
An unnamed reviewer said "The book is outstanding and comes at the right time. It has never been more necessary to recall the positive contribution of cement and concrete to mankind or to make it explainable. [Nobis] has more than succeeded!"
US: ForneyVault has partnered with Command Alkon to improve the quality control process for a mutual customer, Titan Virginia Ready-Mix. The concrete producer, a subsidiary of Greece-based Titan Group, previously relied on both suppliers’ products separately. Now, ForneyVault has integrated Command Alkon ‘s quality control technology into its own data collection software. It says that the integration will benefit the concrete producer’s testing capabilities. Titan Virginia uses Command Alkon’s CommandQC software product to validate the quality for its own internal ready-mix concrete products.
Command Alkon software product owner James Shilstone said “Forney’s decision to place their data in the cloud makes it easy to interface with CommandQC. Sharing data between the two programmes eliminates the need for double entry and makes the test results available to the QC manager more quickly.” ForneyVault vice president, platform development Scott Grumski added “Integration with Command Alkon’s software allows Titan’s quality control technician to lose the clipboard and pencil... The integration partnership reduces risk and advances compliance for Titan’s quality assurance programme.”
Holcim to buy Heinrich Teufel
07 July 2021Germany: Switzerland-based Holcim has agreed to acquire ready-mix concrete and aggregates producer Heinrich Teufel. The Strassburg, Baden-Württemberg-based company employs 160 people across its operations in southern Germany. No value for the purchase has been disclosed and the transaction will be subject to regulatory approval.
Europe, Middle East and Africa regional head Miljan Gutovic said "The acquisition of Heinrich Teufel will strengthen our footprint in southern Germany in aggregates and ready-mixed concrete. We were especially impressed by their shared commitment to advancing the circular economy. We look forward to warmly welcoming the Heinrich Teufel colleagues joining our team.”
Canada: Lafarge Canada has signed a non-binding memorandum of understanding with carbon utilisation company, Carbon Upcycling Technologies. The agreement allows for the potential integration of Carbon Upcycling’s CO2-embedded concrete additive into Lafarge operations and will explore opportunities to expand Carbon Upcycling’s operating capacity by developing larger processing facilities.
Carbon Upcycling produces an additive that makes concrete both stronger and more sustainable with the ability to reduce the carbon footprint of concrete by up to 25% on a lifecycle basis. Carbon Upcycling’s involvement into construction materials began in 2018 through its participation in the LafargeHolcim Accelerator program, which aimed to accelerate the growth of innovations in the building materials industry.
The deal aligns with Lafarge's Net-Zero 2030 pledge to accelerate green construction and combat the climate change crisis with low carbon concrete and circular economy solutions, and Carbon Upcycling goal to reduce overall CO2 emissions by 600Mt by 2030.
France: Cemex France has inaugurated a multi-service green building materials outlet and recycling centre at Genevilliers in Paris, Île-de-France. The company says that the facility will stock its reduced-CO2 Vertua concrete range. It will also receive construction waste, excavated earth and rubble for use in concrete production or resale as aggregates. The company will offer complete traceability of waste received, and non-recyclable waste will be used in quarry restoration.
France North director of materials Alain Plantier said, "Developing construction in high-growth urban locations requires circular economy solutions which mitigate climate change and save natural resources while improving the wellbeing of inhabitants." He added “Cemex is uniquely positioned to provide integrated solutions for building and maintaining more sustainable and resilient cities, and this new site demonstrates this perfectly. Clients in Paris need low-carbon construction solutions which perform throughout their life cycle. Working together with our clients, this site will help to reduce the carbon footprint of new projects in line with Cemex’s Future In Action strategy – committed to net zero CO2.”
