US: Ireland-based Ecocem has appointed Mike Donovan as Technical Director for its US business operations. He will be responsible for overseeing key aspects of Ecocem’s business in the US, with a focus on widespread commercial adoption of the company’s low-carbon cement technologies, including ACT, by the US market.

Donovan most recently developed and brought a new natural pozzolan to market with Geofortis. He started his career in concrete in the 1980s working at companies including as Sherman Industries, Blue Circle Cement Tarmac and Central Concrete Supply (US Concrete). He is a graduate in civil engineering from the University of Texas at Austin.

A couple of stories have popped up this week regarding restrictions on cement imports. First, authorities in Taiwan have launched an anti-dumping investigation into Vietnamese cement. Secondly, and perhaps more surprisingly given its growing economy, the authorities in Kyrgyzstan are planning to ban overland imports of cement from within Central Asia. More on that later…

First, to the Far East, where Taiwan’s Trade Remedies Authority has launched an anti-dumping investigation into cement and clinker imported from Vietnam. It will assess imports covering the year from 1 July 2023 to 30 June 2024 and target seven specific Vietnamese cement producers among others. The Vietnamese companies are mandatory respondents – they will be compelled to answer investigators’ questions.

Vietnamese cement has long been among the cheapest in the region due to the country’s drive to hit production targets, rather than simply meeting demand. The situation has resulted in a vast amount of cement available for export. This, coupled to Vietnam’s long, indented coastline, makes it easy to ship cement overseas.

Even with export volumes falling by 1.2% year-on-year to 31.3Mt in 2023, around a third of Vietnam’s capacity, this is a massive volume of cement - and it’s only getting cheaper. The average export value of Vietnamese cement and clinker fell from US$46-48/t at the start of 2023 to just US$31-32/t in May 2024, a decline of 30-35%. These changes have been due, in part, to an increase in tax on clinker exports from 5% to 10% on 1 January 2023 and an anti-dumping investigation launched by the Philippines in March 2023. Falling prices and volumes represent a ‘double-whammy’ for producers, several of which have announced that they made losses in the first half of 2024. Vicem’s top management said that challenges also arose at home due to a reduced demand following limited civil engineering projects and a stagnant real estate market.

It is easy to see why Taiwanese cement producers may feel threatened by the prospect of greater volumes of cheap cement on their doorstep. Taiwan only made 4.9Mt/yr of cement in the first half of 2024. With domestic prices in the region of US$65-70/t according to Cement Network, this provides a very attractive margin of US$33-39/t for Vietnamese producers to export to Taiwan. It will be interesting to see how far the country’s authorities are willing to go to protect the country’s producers and whether any anti-dumping policies lead to further falls in the landed volumes of Vietnamese cement.

Meanwhile, 4600km to the west, Kyrgyzstan has announced that it will enforce a six-month road import ban on several types of cement including Portland cement, alumina cement and slag cement. The ban, affecting both cement and clinker, will take effect on 1 October 2024 and last for six months. According to the State Statistical Committee of Kyrgyzstan, the country saw a 76% year-on-year increase in cement imports – mainly from Iran, Kazakhstan, China and Uzbekistan - between January 2024 and May 2024. The total import volume over the five months was 125,737t. For a country that made just 1Mt over the same period, this is a major change.

The overland import ban is more of a surprise than the Taiwan / Vietnam situation, as Kyrgyzstan recently reported that the North of the country was experiencing a ‘construction boom’ and cement shortages. However, two new plants due to start production in the coming months could help the country out... unless it too would like to export its newly-developed cement production capacity.

And here we arrive at a ‘classic’ impasse. From Pakistani cement in South Africa, to price arguments in West Africa, import bans in Central Asia and Vietnamese cement in Philippines and Taiwan, more and more exporters are finding that their markets are already self-sufficient in cement, with the US perhaps the notable exception. Soon there will be nowhere left for cement to be exported to. Are we at peak cement?

UK: UK-based startup Cocoon has raised €4.9m in pre-seed funding to develop technology that repurposes byproducts from electrified steel furnaces into a ‘near-identical replacement’ for blast furnace slag, according to the company. The modular technology integrates into existing steel-making processes without disrupting operations or requiring high capital expenditure, reports UK Tech News. Cocoon targets a 50% replacement of cement in concrete, aiming to reduce emissions for producers. Initial tests are underway at a steel plant in northern England, followed by another in the US.

Cocoon CEO Eliot Brooks said "We’re turning a byproduct with little use into a valuable product that the market badly needs and can be easily integrated into existing supply chains. By repairing a broken link in the circular economy, Cocoon provides steel makers with a new revenue stream while meeting the low-carbon material needs of the concrete industry. For every 1t of Cocoon’s slag-based cementitious material used, 1t of CO₂ can be avoided."

Brooks hopes Cocoon's climate technology will be integrated into a pilot plant by late 2025.

UK: A steel and cement co-recycling process developed at the University of Cambridge has received US$2.9m in seed funding. Cambridge Electric Cement is utilising slag produced during the steelmaking process, which uses electric arc furnaces instead of blast furnaces, as clinker for cement. The researchers are conducting a US$8.4m trial called Cement 2 Zero to test the production process, aiming to produce 110t of recycled cement during the two-year program.

US: St Marys Cement won three national awards at the Slag Cement in Sustainable Concrete Awards 2023. The producer won the awards for supplying its slag cement for the construction of Wixom Assembly Park in Wixom, Michigan; of 333 North Water in Milwaukee, Wisconsin, and of Excellerate Manufacturing in Appleton, Wisconsin.

US: Eagle Materials and Heidelberg Materials North America, through their joint venture Texas Lehigh Cement Company, will start up a new slag cement facility. The facility will be located in Houston, Texas and will start production in the summer of 2024. When completed, it will have a production capacity of 500,000t/yr. This is in addition to Texas Lehigh’s cement plant in Buda, Texas.

Netherlands: Ireland-based Ecocem has agreed a deal with Overslagbedrijf Moerdijk (OBM) to expand production and storage capacity at the company’s Moerdijk slag cement grinding plant. The project is intended to allow the unit to both produce and store the company’s advanced cement technology (ACT) product. It will quadruple the storage capacity for key materials at the site up to 40,000t. Ecocem has signed a long-term agreement to lease the site from OBM, who will manage the handling and storing materials on Ecocem’s behalf.

This expansion of the Moerdijk plant is part of Ecocem’s plans to expand its manufacturing and storage capacity to support the commercialisation of ACT across all its plants. It follows the expansion of its Dunkirk plant in France, which was announced in June 2023. These expansion plans will be supported by licencing and partnership strategies to accelerate availability and adoption of scalable low clinker cement at speed.

Conor O’Riain, Managing Director (Europe), at Ecocem, said: “We are increasing our capacity at all of our locations and our deal with OBM is a hugely important aspect of our expansion strategy. It will accelerate our ability to manufacture ACT our low clinker cement technology and make it available commercially by 2026. At the same time, we are actively pursuing licensing and partnership agreements in the construction industry to ensure the benefits of this technology are shared widely and we accelerate progress to Net Zero.”

In February 2024 Ecocem said that its ACT technology received an ETA (European Technical Assessment), which provides the technology with a route to full commercialisation by 2026.

Finland: Boliden says it has a developed a 95% reduced-CO₂ alternative cement production process based on the use of slag. Nordic Daily News has reported that the process has received verification from ‘established players in the cement industry.’ A preliminary study is underway, wherein Boliden will establish a 250,000t/yr production plant. Additionally, the process extracts usable metal from slag.

Ireland/France: Ecocem will showcase its Advanced Cement Technology (ACT) at the Buildings and Climate Global Forum in Paris on 7-8 March 2024. The French Government and United Nations Environment Programme (UNEP) will host the event, supported by the Global Alliance for Buildings and Construction (Global ABC). It aims to advance the climate outcomes of the United Nations Climate Change Conference (COP28) in 2023. Ecocem joins global policy-makers, industry stakeholders and international organisations as the event’s sole international cement technology company exhibitor.

Managing director Donal O'Riain said "The Buildings and Climate Global Forum is happening at a crucial moment for the planet. Urgent and deep decarbonisation of construction materials is essential to achieving the 2015 Paris Agreement targets.” He continued “Ecocem’s ACT low carbon technology can decarbonise the cement sector on a trajectory consistent with 1.5°C of global warming, the first major industry sector to achieve this feat. But we must now mobilise resolutely, rapidly and globally to deploy this technology. The first ambition should be a 50% reduction in CO₂ emissions from cement by 2030. Technology is no longer the barrier."

US: The Department of Transportation has announced a US$5m initiative to investigate the use of steel slag in cement and concrete. This will take the form of a collaboration between the Department of Transportation and a selected US-based steel producer and university partner. The initiative seeks to reduce CO₂ emissions in the production of building materials. Prospective participants may view the grant opportunity here.

Transport secretary Pete Buttigieg said "We're proud to make this funding available to help develop the next generation of construction materials so that the future of our transport infrastructure is more resilient, more sustainable and made in America.”

Robert Hampshire, deputy assistant secretary for research and technology and chief science officer, said “This funding initiative will develop and advance innovative materials and technologies that support the nation’s goals to decarbonise the transportation sector by 2050, strengthen resilience of the nation’s transportation infrastructure, and address adverse environmental impacts created by the transportation system.”
