Holcim 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.

Australia: James Hardie Industries has published its 2021 Sustainability Report, entitled Building Sustainable Communities. The report outlines the group’s sustainable future, commitments and progress to date in four key areas, namely Communities, Environment, Innovation and Zero Harm. The framework uses measurable goals, such as a 40% greenhouse gas reduction between 2019 and 2030, a 5% increase in gender diversity in management positions between 2020 and 2024 and an increase in the proportion of revenues covered by environmental product declarations to 80% from 26% in the 2021 financial year. Formalised in the 2021 financial year, the sustainability strategy is integrated with James Hardie’s global strategy for value creation and operational performance.

Chief executive officer Jack Truong said “Our commitment to building better, more sustainable communities starts by building better homes, with the homebuilding materials of the future.” He added “Our commitment to a sustainable future extends to our James Hardie community, the local communities in which we operate and across the largest shared community of all, our global ecosystem. At James Hardie, we are transforming the way the world builds by offering better, safer and more sustainable products.”

World: Switzerland-based Holcim has launched its ECOPlanet reduced-CO₂ cement range in six European markets and Canada. The range offers at least 30% lower emissions than Ordinary Portland Cement (OPC). It includes one cement produced using recycled construction and demolition waste.

Chief executive officer Jan Jenisch said “Driving the circular economy, our ECOPlanet range includes the world’s first cement with 20% recycled construction and demolition waste inside, advancing our net zero vision in a nature-positive way. With the world’s population rising and rapid urbanisation, solutions like ECOPlanet are critical to enable greener cities and smarter infrastructure, building more with less.”

The group plans to introduce the range to 15 countries by 2022 and double its market presence in 2023.

Germany: HeidelbergCement has signed the Science-Based Targets Initiative’s (SBTi) Business Ambition for 1.5°C commitment and joined the United Nations (UN) Framework Convention on Climate Change Race to Zero campaign. The former entails a commitment to limiting global warming to 1.5°C and achieving net zero carbon emissions by 2050. Race to Zero membership entails a positive commitment to beginning the transition to a decarbonised economy before the UN Climate Change Conference of the Parties in November 2021.

Chair Dominik von Achten said “As one of the world's leading building materials producers, we are continuously increasing our efforts in the global fight against climate change. We are working on all levels to reach climate neutrality – within our operations as well as through associations and initiatives such as the Race To Zero campaign. Every effort brings us closer to our goal.”

UK: 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.”

There has been a significant investment in the South Korean cement industry this week with the news that Hanil Hyundai Cement has ordered a steam-based waste heat recovery (WHR) system from Japan-based Kawasaki Heavy Industries. The 22.6MW system will be used on two of the production lines at the Yeongwol plant in Gangwon Province. The supplier says that installation is expected to generate about 30% of the energy the plant needs and save around 10,000t/yr of CO₂ in the process. Delivery is scheduled for late 2022.

This order may be the first investment following the announcement in late June 2021 that the state-owned Korea Development Bank had pledged around US$870m towards supporting the cement sector in making carbon reduction upgrades by 2025. These are intended to include moving away from burning fossil fuels in cement production and increasing the use of recycling materials. At the time of the agreement between the bank and the Korea Cement Association (KCA), Hanil Hyundai Cement noted that the local alternative fuels substitution rate was 24% compared to 46% in the European Union and 68% in Germany.

By European or American standards South Korea kept its coronavirus cases under control in 2020. A robust testing and contract tracing regime (K-Quarantine) managed to prevent the country enforcing stricter measures until late in 2020. A fourth wave of infections, currently underway in July 2021, due to the more contagious Delta variant, has started to change this. Despite being able to keep its economy open though, the construction sector still took a hit although not as bad as initially feared.

Cement production fell by 6% year-on-year to 47.5Mt in 2020 from 50.6Mt in 2019 following a downward trend since 2017. The KCA expected worse after a poor third quarter in 2020 when it was preparing for shipments to fall below the level last seen in the midst of the International Monetary Fund (IMF) crisis in the late 1990s. On top of this the industry was also potentially facing a new tax on production towards the end of 2020. One large local producer, Ssangyong C&E, reported a 5% year-on-year drop in sales to US$864m in 2020 from US$910m in 2019. However, it managed to increase its operating profit over the same period. So far in 2021 the sector faced supply shortages in the spring. The KSA blamed the winter plant maintenance schedule and a lack of railway wagons and trucks.

The timing of the Korea Development Bank investment in the cement sector is interesting given the movement on the European Union carbon border adjustment mechanism. Cement exports seem unlikely to be affected but business lobbyists like the Federation of Korean Industries are well aware of the effects schemes like this might have upon commodities like steel and aluminium in the first phase and then the implications for car production later on. Target markets for cement exports such as the US, Peru, Chile and the Philippines might all become vulnerable should carbon-based trade restrictions become more prevalent. Of course export markets remain vulnerable to more usual hindrances. For example, in March 2021 the Philippines extended its safeguard measures on cement imports to various countries including South Korea.

Following a round of market consolidation in the late 2010s, the South Korean cement sector now appears to be entering a phase of sustainable realignment. In late May 2021 Prime Minister Moon Jae-in announced plans to hasten the country’s carbon reduction targets ahead of the United Nations Climate Change Conference scheduled for November 2021, including a carbon tax. With cement production on a downward trend since 2017 and the coronavirus crisis far from gone it will be instructive to see how far the intervention of the Korea Development Bank will go.

Belgium: The European cement association Cembureau says that the European Union’s (EU) upcoming ‘Fit for 55’ emissions legislation must provide an enabling regulatory framework for the cement industry’s carbon neutrality roadmap. Key issues of concern to the association are the prevention of carbon leakage, the retention of free allocation and a carbon border adjustment mechanism (CBAM) until 2030 and the need for a ‘coherent package’ to boost the uptake of low-carbon technologies. It said that the industry supports the European Green Deal and the major challenge of delivering deep emissions cuts by 2030.

Chief executive officer Koen Coppenholle said “Whilst we welcome that the CBAM will seek to bridge the widening gap in carbon costs between EU and non-EU countries, the proposed phase-out of free allocation and the absence of export rebates would cause significant risks to investments.” He added “The decision not to include indirect emissions at this stage is also regrettable.”

Germany: A consortium of Mexico-based Cemex subsidiary Cemex Deutschland, Uckerwerk Energietechnik subsidiary Enertrag and hydrogen specialist Sunfire has announced a cement industry decarbonisation project called Concrete Chemicals. The project will see sequestered CO₂ combined with hydrogen to produce hydrocarbons for use as cement fuel. The consortium has submitted a funding application to the German Ministry for Environment, Nature Conservation and Nuclear Safety for a trial at Cemex’s Rüdersdorf, Brandenburg, cement plant. This would help in the realisation of the plant’s 2030 carbon neutrality target. Alongside a 5000t/yr demonstration plant, the site will have a green hydrogen plant, supplied by Sunfire. When commissioned in 2025, the plant will produce synthetic fuels and other hydrocarbon fractions. The consortium is also investigating a methanol synthesis route using synthetic gas.

Europe, Middle East and Africa regional president Sergio Menendez said “We support the urgency of action to address the climate challenge and have committed to a 55% reduction in CO2 from our 1990 baseline in our European operations by 2030. Together with our industry partners, we can collectively transform ourselves into a CO₂-neutral world. Concrete Chemicals is a promising project.”

Greece: Titan Cement has received the validation of the Science-Based Targets Initiative (SBTi) for its CO₂ emissions reduction targets. The validation confirms that the company’s targets are in line with a well-below 2°climate change scenario.

The group aims to reduce Scope 1 emissions per tonne of cementitious product by 21% by 2030 from 2020, and to reduce Scope 2 emissions by 42% within the same parameters. Additionally, it has committed to drive down the CO₂ footprint of its operations and products with the aim of delivering 100% carbon-neutral concrete by 2050. Methods include increasing the use of alternative fuels, accelerating efficiency-improving initiatives, developing low-carbon products, and adopting innovative technologies and solutions. The company says that it will also monitor and independently verify its supply chain emissions.

It said “Through the participation in European and international consortia, as well as through collaborations in research and development, Titan Group will continue to develop low-carbon cementitious products and pilot carbon capture technologies in its plants, actively contributing to the industry’s ambition for a carbon-neutral future.”

Canada: Progressive Planet and sustainable construction company ZS2 have signed a letter of intent to collaborate on green cement technologies development. The pozzolan-based cement producer will supply ZS2 with 10,000t/yr of natural pozzolan, beginning in late 2021. It will also purchase US$300,000-worth of shares in ZS2. The companies will also explore sequestering CO₂ in magnesium-based cements.

ZS2 chief executive officer Scott Jenkins said "The technical collaboration between PLAN and ZS2 continues to grow. The potential to reduce the carbon footprint of innovative cement products is significant with the combination of our mutual research and commercialisation to date. ZS2's growing portfolio of high performance, fire-resistant and sustainable building technologies will be greatly enhanced by our expanding partnership, and we are extremely excited about our shared future potential."
