China: Hoffmann Green Cement, which produces clinker-free cement products has been granted a Chinese patent, No. CN 201880079822.X, for its clay-based H-EVA cement. The patent comes a year after a similar patent for its H-P2A binder.

H-EVA is a clinker-free cement that is based on an alkaline ettringitic technology. It uses activated clay and is presented in the form of a powder that can be stored in a silo. With a mechanical strength of up to 60MPa at 28 days, its strong technical performance makes it suitable for all types of concrete applications in buildings and on roads.

Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies, said "Following the granting of a first patent for our H-P2A technology, we are delighted to announce the strengthening of our intellectual property in the Chinese market with the granting of a patent for our clay-based H-EVA cement. This confirms once again our technological lead and the relevance of our low-carbon solutions".

France: Hoffmann Green Cement Technologies has won a contract to supply property developer Belin Promotion with its clinker-free cement for use in its residential property development projects up until March 2026. Dow Jones Institutional News has reported that the deal includes minimum volume commitments.

Congratulations to Lafarge France for launching the first calcined clay cement unit in Europe. The subsidiary of Holcim says that the unit, based at the integrated Saint-Pierre-la-Cour cement plant, is the first of its kind on the continent. It is using the company’s proprietary proximA Tech technology and will produce up to 500,000t/yr of cement in its ECOPlanet range. The operation is also powered with biomass alternative fuels and uses a waste recovery system to further drive down overall CO₂ emissions. Once production ramps-up the producer expects that 30% of cement from the Saint-Pierre-la-Cour plant will be from the ECOPlanet range by 2024.

The investment at Saint-Pierre-la-Cour was Euro40m. Holcim is also producing calcined clay cement at its La Malle plant in France. It received an investment of Euro6m in 2022 to produce low-carbon cements. Together, both plants are aiming to produce over 2Mt/yr of calcined clay cement by 2024. As is usual for these kinds of projects, the French government partly funded the clay calcination unit at Saint-Pierre-la-Cour as part of the ‘France Relance’ scheme investing in large-scale decarbonisation and energy efficiency initiatives.

Calcined clay cements in Europe aren’t exactly new, but Holcim’s new unit in France does appear to be the first full-scale line located at a cement plant. Research by OneStone Consulting, for example, reckons that the first flash activated clay unit expressly set up to supply the cement sector was commissioned in 1995 in Toulouse, France. More recently, Hoffmann Green Cement inaugurated its 50,000t/yr pilot plant at Bournezeau in France in 2018. This site produces cements made from flash calcined clay and blast furnace slag, although it is unclear how demand for the different products varies. A new 0.25Mt/yr plant in the Vendée department was scheduled for commissioning in the second half of 2022. Another 0.25Mt/yr plant in Dunkirk is expected to be commissioned in the second half of 2024.

Cementir Group launched its calcined clay cement product FUTURECEM in Denmark in 2021 with production via a pilot plant. It then extended this to the Benelux and French cement markets in 2022. As part of its industrial plan for 2021 - 2023 it was planning to build a clay calcination unit to support the growth of FutureCem. FLSmidth revealed in June 2021 that it had won a contract to build a 400t/day clay calcination unit for Vicat’s Xeuilley integrated cement plant. The deal was worth around Euro27m and commissioning is scheduled for 2023.

Firstly, it is interesting to see a focus on France for some of the projects above. The presence of Lafarge’s technical centre in Lyon may explain the interest for that company. However, Hoffmann Green Cement and Vicat are also active in the field. It is worth noting that France also holds a busy secondary cementitious material market with standalone operators including Ecocem, Cem’In’Eu and Hoffmann Green Cement. Secondly, despite the early start, clay calcination for cement is currently more active outside of Europe. In Africa, for example, there is at least one live full production line and a number of other projects on the way. Various other pilots and projects are also happening elsewhere around the world, often in conjunction with the limestone calcined clay cement (LC3) initiative. Where calcined clay cement production in Europe goes from here is uncertain at present as it is one solution among many for lower carbon cement products in the future. Yet, the projects that have made it so far to the commercial scale will be watched closely by the companies that have invested in them - and their competitors.

France: Hoffmann Green Cement Technologies is supplying its low-CO₂ clinker-free cement for the construction of an industrial prototype glass wool recycling plant in Chemillé-en-Anjou by Saint-Gobain subsidiary Isover. The company will supply its H-UKR cement for use in the facility’s foundations.

Hoffmann Green Cement Technologies co-founders Julien Blanchard and David Hoffmann said "This unprecedented project is totally in line with what we want to embody since the creation of Hoffmann Green: the promotion of the circular economy in the construction sector through the revalorisation of waste from industry."

UK: Hoffmann Green Cement Technologies, a French company that manufactures and distributes low-CO₂ clinker-free cement, has announced that it has signed its first partnership agreement in the UK with Cemblend, a supplier of customised cement powder mixes.

Hoffmann Green will supply Cemblend with its H-IONA, H-UKR and H-EVA clinker-free decarbonated cements for distribution to its customers in the UK and Ireland. This exclusive distribution agreement with volume commitments initially runs until the end of 2023 and is a first step towards the signature of a licensing agreement which could see Cemblend build and operate a production unit similar to Hoffmann Green's French production facilities.
Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies said, "We are pursuing the milestones of our international development with the signing of this structuring partnership in a strategic market in Europe. This first distribution contract in the UK is further proof of the attractiveness of our low-carbon solutions outside our borders. It is a first step in our cooperation process with Cemblend to build eco-responsible buildings across the Channel."

A trio of slag cement stories have been in the sector news this week with reports from Australia, France and Sri Lanka. Of note from the first two reports is a focus on supplies of slag.

The first concerns Hallett Group’s US$80m supplementary cementitious materials (SCM) project in South Australia. This will see the company process slag and fly ash sourced from sites in the region to manufacture blended cement products and standalone SCMs. These will be principally milled, blended and distributed from a site at Port Augusta. However, an additional distribution site at Port Adelaide is also planned that can both import and export the company’s products in a bid to cut down on supply chain risk, particular for its mining customers. The company says it will replace up to 1.15Mt/yr of cement when fully operational, although initial production looks set to be about a third of this based on local media reports. Commissioning of the Port Adelaide distribution hub is scheduled for May 2023, following by the Whyalla Granulator in January 2024 and the Port Augusta processing plant in June 2024. Pointedly, Hallett Group is explicit about where is plans to source its SCMs from: Nyrstar Port Pirie and, potentially, Liberty GFG.

The second slag-themed story hails from France, where Hoffmann Green Cement has acquired ABC Broyage, which operates a slag grinding plant in North Dordogne. Like the project in Australia above, Hoffmann Green is focused on its supply chain. With this acquisition it will be able to grind its own blast furnace slag instead of buying it. Raw blast furnace slag will be imported via the port of La Rochelle where the company has storage silos. It will then be ground at the former ABC Broyage site and sent on to Hoffmann Green’s H1 and H2 production sites, located at Bournezeau in the Vendée region. Finally it will use it to manufacture its H-UKR and H-IONA cement products. There is no mention of how much the acquisition is costing Hoffman Green. Instead the emphasis, according to company founders Julien Blanchard and David Hoffmann, is very much to, “strengthen our control over our supply and secure our margins in the current highly inflationary context.”

Finally, the week’s third slag-themed cement story is from Sri Lanka, where local media reports that Insee Cement has started producing Portland Composite Cement, using SCMs such as slag, at its Ruhunu grinding plant. This story follows the trend of cement producers around the world switching to greater usage of blended cements, often for sustainability reasons. Unfortunately, political events in Sri Lanka are overshadowing everything else locally, with the president having fled amid social unrest provoked by the ongoing and severe economic crisis. To this end Insee Cement has astutely also donated medical supplies this week to the intensive care unit at the Colombo National Hospital.

These slag stories are important for the cement sector can be demonstrated by a recent update to the Center for International Climate and Environmental Research - Oslo’s (CICERO) research on global CO₂ emissions from cement production. When it published its estimate for 2021 it found that overall emissions were 2.6Bnt in 2021 or just over 7% of the world’s total CO₂ output. What is worse though, is that its data suggests that cement-based emissions have steadily grown year-on-year from 1.2Bnt in 2002. Apart from a dip in 2015 they have kept on rising! This can mostly be attributed to the growth of the Chinese cement industry in the early 2000s suggesting that a tipping point may be reached in the current decade as lowering cement production CO₂ intensity finally kicks in.

Slag and other SCM-based blended cements fit in here as they are one of the ‘easiest’ ways to reduce the clinker factor of cement and concrete and thereby reduce the sector’s CO₂ levels. Hence they keep popping up on the various roadmaps and reports for the cement industry to reach net zero. The flipside of this however is that slag is becoming harder to source as the demand for granulated blast furnace slag increases and less new steel plants get built, especially in North America and Europe. Hence the focus on the supply of slag in the first two news stories above. Blended cements may be the future but getting there will be far from simple.

France: Hoffmann Green Cement Technologies has acquired ABC Broyage, which operates a slag grinding plant in North Dordogne. The producer says that ABC Broyage will import granulated blast furnace slag (GBFS) via La Rochelle and supply ground GBFS to its H1 and H2 green cement plants in Bournezeau. This will give Hoffmann Green Cement Technologies self-sufficiency in its raw materials processing.

Co-founders Julien Blanchard and David Hoffmann said “Managing our supply chain has always been one of Hoffmann Green's strategic priorities. After securing our supplies of co-products and their storage, we are now focusing on optimising their processing through the acquisition of ABC Broyage and the development of vertical integration.” Blanchard and Hoffmann noted that, besides strengthening the company’s control over its raw materials supply, ABC Broyage’s slag grinding capacity also secures its margins in the ‘current highly inflationary context.’

Switzerland: Hoffmann Green Cement Technologies has launched a new joint venture with a Switzerland-based construction industry partner. Hoffmann Green Cement Technologies will hold a minority stake in the new subsidiary, which will produce its reduced-CO₂ clinkerless cement at an upcoming plant. The producer says that the unit will apply the vertical production model of its existing H2 plant in France.

Co-founders of Hoffmann Green Cement Technologies Julien Blanchard and David Hoffmann said "After signing our first contract outside France more than a year ago, we are proud to accelerate our international development through a licensing model for Hoffmann Green technologies and processes. The opening of this first subsidiary in Switzerland proves the attractiveness of our carbon-free solution without clinker outside our borders, and constitutes a structuring step in the development of Hoffmann Green."

France: Low-CO₂ cement manufacturer Hoffmann Green Cement Technologies has signed an exclusive partnership with IBAU Hamburg to build all future Hoffmann Green Cement units.

As the general contractor for the second production site (H2) currently under construction at Bournezeau, France, IBAU Hamburg also will be responsible for the exclusive management and construction of the third production site (H3) in Dunkirk, France. It will also build international sites, to be established at a number of locations in Europe and, subsequently, outside of Europe. IBAU Hamburg will handle the entire construction process for each project, from the design stage to the completion of the unit. All of the units will be built entirely with Hoffmann Green decarbonated and clinker-free cement.

France: Hoffmann Green Cement Technologies recorded sales of Euro2.38m in 2021, more than four times its 2020 figure of Euro504m. The company’s losses before interest, taxation, depreciation and amortisation (LBITDA) declined by 27% to Euro5.23m from Euro4.13m, while its net loss fell by 9.1% to Euro5.56m from Euro6.12m.

The producer confirmed its global sales target of Euro130m and EBITDA margin target of 40% by 2026, by which time it expects to have achieved sales of 550,000t/yr of its clinker-free cement in France. This would correspond to 3% of the domestic cement market. By 2026, it aims to operate four plants abroad.
