The Portland Cement Association (PCA) has launched a new website to promote the US cement industry’s progress towards net zero. It’s always interesting to see the different approaches the various associations around the world take in promoting the sector especially in response to mainstream media coverage that has often taken a negative view of cement and concrete. As sustainability thinking has permeated into society the stereotype that cement production releases vast amounts of CO₂ for little gain has been a hard one to shake off. Readers can draw their own conclusions on how well the PCA site works by looking at cementprogress.com.

Make no mistake, the PCA’s new website is a marketing tool designed to bring out some of the points of its carbon zero roadmap to a wider audience. Yet it is refreshing to see a national association website attempting to tell the general public what progress the cement industry is making towards reducing its CO₂ emissions. Unfortunately, it then avoids giving out any data that presents an overview of how it’s all actually going. This may come with time though as the roadmap was only released in late 2021. One number that does stick out on the site is that the PCA uses the Environmental Protection Agency’s (EPA) carbon emissions data to calculate that the manufacture of cement accounts for 1.25% of total CO₂ emissions in the US. This is lower than the global figure of 7% that is often used from the Center for International Climate and Environmental Research - Oslo’s (CICERO) research. Both figures appear to be broadly correct based on the available data.

The real story here is to showcase the wide range of actions the PCA is taking as part of its roadmap. In the cement section, for example, the PCA is rightly able to demonstrate its recent work driving the transition to Portland Limestone Cement (PLC) production in the US. This then leads on to the usual beats of resilient construction, carbonation and a ’whole society’ approach to tackling the decarbonisation of the cement industry with suggestions that everybody from citizens to contractors to policy makers can do.

The wider context is that the big challenge facing cement advocacy groups today is that sustainability is a global issue but that such groups have generally been national or regional for most of their history. The national or regional cement associations have existed for decades serving the local needs of their members. This started to change in 1999 when the Cement Sustainability Initiative (CSI) was created with its global approach to sustainability for the sector with its data gathering and technology roadmaps. In the 2010s global media attention started to focus on the large share of CO₂ emissions the cement industry was emitting as, coincidentally, China became the world’s largest cement producer. Then in the late 2010s the two global cement associations - the Global Cement and Concrete Association (GCCA) and the World Cement Association (WCA) - emerged with the GCCA taking over what the CSI did previously.

One problem that the PCA and the other associations face is that decarbonising the cement and concrete sectors is hard to do, expensive and will take decades. Until, or if, carbon capture is suddenly conjured up at scale, all of this work is inherently seen as boring by much of the media compared to, say. young photogenic environmental activists supergluing themselves to roads. One way to fight back against this is to show progress font-and-centre and to try and take back control of the narrative. This appears to be what the PCA is trying out in a more direct fashion than usual. The risk though is that any action by an industry-backed lobbying group to show off the work it is doing will simply be labelled as greenwashing, whether it’s fair or not. Of course, some environmentalists indulge in their own reverse version of this (industry staining?) to make the powerful but simple argument about the necessity of cutting CO₂ emissions but without taking fully into account or underplaying the scale of the societal changes necessary to do so. Either way, the cement industry and its advocates have an uphill struggle on their hands in the years ahead. This may require fresh thinking about how to win over hearts and minds.

The March 2023 issue of Global Cement Magazine includes an interview with Claude Lorea from the Global Cement & Concrete Association (GCCA)

Spain: Holcim España has appointed José María Gómez as the director of its Jerez cement plant near Cadiz. Gómez previously worked as the Head of Production at the Montcada i Reixac cement plant near Barcelona. He holds over 15 years of experience with the company, including in Malaysia. He is a graduate in environmental sciences from the University of Castilla-La Mancha.

Algeria: Lafarge Algeria has appointed Redouane Djazairi as a plant manager. He has worked for the subsidiary of Holcim for nearly 20 years in a variety of quality control and performance roles. Most recently he held the position of Production Manager. The cement producer operates two integrated plants in the country, at M'Sila and Oggaz respectively.

India: Star Cement has appointed Arindam Acharya as its technical head based at Guwahati in Assam. He was worked in the cement sector for over 15 years, mostly recently holding the post of Assistant General Manager at Dalmia Cement (Bharat). Prior to this he has worked for The Ramco Cements, Ambuja Cements and UltraTech Cement. Achary holds qualification from Shivaji University and the Indian Institute of Management in Kolkata.

India: Sika India has appointed Parag Solanki as its Director of Technology. He previously worked as Vice President- R&D at ACC. Before this, Solanki held a variety of research and development roles at Sika. He also worked for UltraTech Cement and Shree Cement. Solanki holds a PhD from Jai Narain Vyas University in Jodhpur as well as a further qualification from the Indian Institute of Management in Kolkata.

Colombia: Cementos Argos has introduced a share price recovery programme at the same time it has released its financial results for 2022. It plans to spend around US$50m on a share buy-back program. Its sales revenue rose by 24% year-on-year to US$2.37bn from US$1.92bn. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 7% to US$422m from US$396m. However, its net income dropped by 14% to US$81.7m from US$95.5m due to mounting financial expenses. Its cement sales volumes fell by 3.7% to 16.2Mt in 2022 from 16.8Mt in 2021.

The group blamed the decline in cement sales volumes on problems in the Haitian market as well as lower trading volumes to the Caribbean and Central America region. Sales volumes of cement and revenue grew in the US but earnings fell. In Colombia, local cement sales volumes fell but were boosted overall by exports.

Germany: Austria-based Rohrdorfer has started up an amine-based carbon capture system at its Rohrdorf cement plant in Bavaria. The producer plans to ultimately expand the system up to a capture capacity of 1500t/day. The inauguration follows a successful continuous trial of the technology since August 2022, excluding a regular kiln maintenance period over winter. Austria-based Andritz designed the system specifically for the Rohrdorf cement plant. It yields CO₂ that is suitable for numerous applications, including in food and beverages and in intermediate products in pharmaceuticals production. The Rohrdorf cement plant also hosts a formic acid plant which uses captured CO₂.

Rohrdorfer aims to achieve carbon-neutral cement production by 2038. Alongside production-related optimisations, the producer plans to realise its aim through a future expansion to the Rohrdorfer plant’s carbon capture system and the implementation of a further carbon capture upgrade at a second cement plant in Austria.

Chile: Melón’s sales rose by 2% year-on-year to US$305m in 2022. The producer recorded a 17% drop in its cement production to 1.13Mt. Operating costs rose by 11%, with rises across raw materials, transport and utilities costs. As such, the producer reported a net loss of US$12m, compared to a net profit of US$15.3m in 2021.

Melón noted a ‘very challenging market’ with ‘active competition’ so far in 2023, including a low capacity utilisation situation in the domestic cement industry.

Thailand: Switzerland-based Maerz has commissioned a new 150t/day lime kiln at Bangkok CaO’s plant at Saraburi. The kiln is the third Parallel Flow Regenerative (PFR) unit that Maerz has supplied to the site following previous installations in 1996 and 2008. All the kilns at the plant use waste oil as a fuel.

Russia: Eurocement has changed its name to Cemros. The rebranding exercise followed an internal staff competition to come up with a new name followed by a vote from a shortlist. The new name is intended to invoke the words ‘cement’ and ‘Russia.’ It was suggested by Evgeny Lukanovsky, Alexey Lotarev and Igor Efimov.

Eurocement was acquired by Smikom in 2021 for around US$2.2bn following an auction held by Sberbank.
