Colombia: LafargeHolcim subsidiary Holcim Colombia has launched Eco, a cement bag label detailing products’ CO₂ emissions reduction by comparison to Ordinary Portland Cement (OPC), on its Boyacá Súper Fuerte and Holcim Maestro cements. The La República newspaper has reported that the labels signal the company’s commitment to the Business Ambition for 1.5°C anti-climate change initiative.

Executive president Marco Maccarelli said that the launch is one more step on company’s path towards Net Zero and sustainable construction, engaging the entire value chain.

Mexico: Holcim Mexico has launched its Holcim Supra range of cements. The company says that products contain a unique three-in-one technology for water repellence, construction optimisation and protection against environmental agents. It says that the use of Holcim Supra cements gives buildings greater sustainability compared to normal ordinary Portland cement (OPC).

Commercial Director Francisco Shwortshik said, “The new Holcim Supra Cement family are the latest in the market in innovation, with integrated three-in-one technology especially developed to protect buildings by reducing the passage of moisture in concrete. In addition to maintaining the attributes of the current
Holcim cement and mortar, they contribute to sustainable building by reducing CO₂ emissions by up to 13% in the process of construction, which makes it an eco-friendly product.”

Chief executive officer Jaime Hill Tinoco said, "Innovation is key to reaching our goal of zero net emissions; this is why at Holcim México we have the strongest research and development organisation in the industry to present and promote consistently high-quality materials and solutions for our clients across the country - like Holcim Supra, a family of unique products on the market that will change Mexico’s way of building.”

Andrew Minson from the Global Cement and Concrete Association (GCCA) kicked off this week’s Virtual Global Concrete Conference with an overview of concrete’s role in the association’s 2050 climate ambition. The association announced in September 2020 that it was starting work on this roadmap for publication in the second half of 2021, just in time for the 2021 United Nations Climate Change Conference, currently schedule to take place in Glasgow, Scotland in November 2021. Minson ran through the topic, providing an overview of concrete’s intrinsic sustainable features and the policy levers the association is considering for its forthcoming roadmap.

One point from circular economy aspects of the plan included design for dis-assembly (DfD) and long life, loose fit modes of thinking around how a building using concrete should be conceived, designed, built, used and - crucially – reused. Long life, loose fit, low energy (to use its original name) was promoted by the Welsh architect Alex Gordon from the early 1970s. It covered themes of sustainability, flexibility and energy efficiency for building design ahead of both the 1970s oil crisis and the current climate one. DfD emerged in the 1990s as a way of thinking about a building’s demolition at the start and working from there. Deconstruction or demolition is prepared for through planning and design. It allows components and materials to be removed more easily, facilitating their subsequent reuse. So, components and materials can be removed more easily allowing their subsequent reuse and elements such as columns, walls, beams, and slabs can be disassembled to facilitate this. Last year Global Cement Weekly explored a similar path with the ideas of Dutch architect and commentator Thomas Rau (GCW348) and his concept of building materials as a service, following on from the Building Information Modelling (BIM) system, and the suggestion that companies simply rent (!) building materials from their manufacturers to encourage whole life thinking.

Just how much concrete the world uses each year is a question beyond the scope of this article, given its range of applications and diversity of users. For example, the Cement Sustainability Initiative (CSI) estimated 25Bnt in 2009. Later, the International Organization for Standardization (ISO) technical committee for concrete, reinforced concrete and pre-stressed concrete placed the figure at around 33Bnt in 2016. It is worth considering how and where concrete is actually used. The chart above from the European Ready Mixed Concrete Organisation (ERMCO) shows how its members used concrete in 2018. Note that use in buildings comprised the biggest share, nearly two thirds, but that the rest included infrastructure, pavements, roads and more. Lifecycle thinking and its various offshoots can apply to all of these applications. Yet it’s easier to imagine a concrete building shell being reused within its lifespan than, say, a bridge or a road. Concrete used in infrastructure seems more suitable for re-use further down the waste hierarchy, such as recycling as an aggregate.

A few final thoughts to consider are that both Cemex and gypsum wallboard manufacturer Etex have invested in modular and/or offsite construction companies in January 2021. Both targets were relatively small companies suggesting growing interest in these sectors by larger players. Offsite building construction suits lifecycle thinking well because the modular components start off being built elsewhere before installation. Factoring in what happens afterwards should be relatively easy and expandable at scale. Finally, LafargeHolcim announced this week that it is acquiring two ready-mix concrete and aggregate suppliers in France and Italy that will give it 35 concrete plants in the region.

Sustainability places lifecycle thinking into mainstream building practice and some methods and tools will inevitably make it into any policy framework the GCCA will recommend. Whether some or all of the ideas above hang around remains to be seen but lifecycle thinking in some form or another is here already and not going anywhere.

Germany: Holcim Deutschland has signed a contract supplying its Lägerdorf and Höver integrated cement plants with 30,000MWh of offshore wind power. The electricity will be supplied by Ane Energy from a number of wind farms.

Uganda: Hima Cement has introduced Kafluu, a chatbot-led initiative that lets customers order products via WhatsApp. The subsidiary of LafargeHolcim says that customers can use the platform 24 hours a day, 7 days a week to manage their orders and transactions. The automated chatbot software guides customers through the ordering process, gathering specifics like the product type, number of bags, delivery site and payment options. Payment is available via MTN MoMo Pay or bank transfer.

“We are always looking to improve the customer experience and Kafluu is able to respond quickly and effectively, enabling customers to place orders, make payments and input their delivery information with ease,” says Israel Tinkasimiire, the Hima Cement Sales Director.

The initiative is being piloted in Mbarara first before rollout in the rest of the country.

France: Mexico-based Cemex has sold 24 concrete plants and an aggregates quarry in southeast France to Switzerland-based LafargeHolcim. Finalisation of the deal is expected in April 2021 and no approval by competition bodies is required. No value for the sale has been disclosed. The group said that the divestment is part of its strategy of focused portfolio development into high-growth markets.

France: LafargeHolcim subsidiary Lafarge France has completed the renovation of its 70m³/hr Larrieu concrete plant in Toulouse, Haute-Garonne Department. The renovated facility is equipped with six cement silos, two of which are dedicated to low-carbon cements for the production of ECOPact low-carbon concrete. It also has eight aggregate hoppers, including one dedicated to recycled concrete aggregates, and two mixer loading stations with forward truck access for safety. The total cost of the upgrade was Euro3m.

Haute-Garonne sector head Vincent Pelloquin praised the project’s speed and ability to rebuild the concrete plant in the middle of the coronavirus pandemic.

Lafarge France is presently engaged in a systematic modernisation of its concrete plants.

US: Switzerland-based LafargeHolcim has become a founder member of the MIT Climate and Sustainability Consortium with the Massachusetts Institute of Technology (MIT). The group says that the consortium aims to accelerate climate action through innovation. It says that it will represent the building materials industry in working with MIT’s research team to develop ‘scalable solutions’ to tackle climate change. It joins 12 other companies, including Apple, Boeing and IBM.

Chief executive officer Jan Jenisch said, “I am committed to building a net zero future, driving innovative and sustainable building solutions that work for people and the planet. With the urgency of today’s climate crisis, no single organisation can tackle it alone. That’s why I am proud to be joining MIT’s alliance of like-minded industry leaders and academic partners to scale up our climate action together.”

Ghana/Nigeria: LafargeHolcim subsidiary Lafarge Africa plans to sell its 35% subsidiary Continental Blue Investment (CBI) Ghana. CBI Ghana runs the Supacem brand from the Tema Free Zone near Accra. It reportedly started building a cement grinding plant at the site in 2017 for a cost of US$55m.

Canada: LafargeHolcim subsidiary Lafarge Canada, Svante and France-based Total have completed Phase 2 of the CO₂MENT carbon capture and storage (CCS) project at Lafarge Canada’s Richmond cement plant. The completed phase consisted of construction and installation of the CO₂MENT technology to capture and filter the flue gas. Lafarge Canada said that Phase 3, scheduled for construction over the next three years, will include the installation of a liquefaction unit, the development of an expansion project to further reduce emissions and a business case review for further expansion across the Lafarge network

Western Canada president and chief executive officer Brad Kohl said “This has been a turbulent year for business and people due to the Covid-19 pandemic with many large scale projects being put on hold, but the perseverance that the people working at the Richmond cement plant continue to show is evident in the success of Project CO₂MENT.” He added “To continue leading change in the building materials industry means we are always looking to partner with like-minded thought leaders such as Svante and Total. This partnership is showcasing our drive towards a net-zero future, and we are seeing this vision become a reality right now with the completion of this phase.”
