Germany: Dyckerhoff has launched Dyckerhoff Weiss Blue Star, a pozzolanic white cement CEM IV/A (P) 42.5 R product. It was approved by the German cement association, the VDZ, in mid-June 2023 and is now being manufactured at the Amöneburg plant. The lower CO₂ credentials of the new product have been promoted as it releases around 15% less CO₂ compared to CEM I cements. It is also notable for being a blended white cement.

Cement producers in Bangladesh received a surprise at the start of June 2023 when the government budget proposed increasing the duty on imported clinker. The Bangladesh Cement Manufacturers Association (BCMA) reacted this week by calling for the duty on clinker to be reduced, while also calling for the same for a non-adjustable advance income tax (AIT) applied to associated imports and sales.

During a press conference, reported upon by the Financial Express newspaper and other media, BCMA president Alamgir Kabir said that the customs duty on key raw materials for the sector had previously been around 5% of the import value. However, he argued that the new suggested increased tariff was “disproportionate” because it placed the burden at 12 - 13%. He urged the government to treat the cement sector as a "priority sector" given that it was facing higher prices generally due to the aftermath of the Covid-19 pandemic, the energy shocks from the Russian invasion of Ukraine and negative currency exchange effects.

The BCMA’s latest lobbying call may sound familiar because it follows a similar battle against import charges from late 2022. A supplementary duty was introduced in November 2022 when the National Board of Revenue (NBR) changed the way limestone was coded in response to a significant increase in imports from 2020. At the time, the price of limestone imports reportedly nearly doubled. The BCMA may have won this battle because in March 2023 the NBR withdrew its supplementary duty. It did require that importers submit to further scrutiny including an updated Import Registration Certificate and various tax related requirements.

The timing of the NBR’s decision to relax the limestone duty is telling given that the previous month or so six of the country’s seven publicly listed cement producers reported either falling profits or losses for the second half of 2022 or the year as a whole. Only LafargeHolcim Bangladesh bucked the trend with an increase year-on-year in its annual profit after tax in 2022, although it attributed this to 95% volume growth in its aggregates business.

As discussed previously a characteristic of the cement sector in Bangladesh is that the country has no domestic limestone reserves. It all has to be imported. Arusha Ahmed Khan, Shun Shing Group presented a summary of the national industry at the Global Slag Conference that took place in early June 2023 in Düsseldorf. The country has two integrated cement plants and 36 grinding mills operated by 31 companies with a total capacity of 84Mt/yr. At present around 14Mt/yr of new cement grinding production capacity is planned by UK Bangla Cement, MI Cement, Confidence Cement and Dubai Bangla with commissioning dates expected from mid-2023 to mid-2025. Khan revealed that the government switched from British to European standards in the early 2000s leading to a high level (95%) of blended cements on the market. Use of slag cements has grown as more producers commission vertical roller mills and more uptake of slag and other blended cements using secondary cementitious materials (SCM) is expected in the future.

A key vulnerability for a grinding-heavy cement sector, like the one in Bangladesh, is any burden on imports such as logistic costs, currency exchange effects and government tariffs. Sure enough each of these examples has been reported locally. The government says that its proposed higher import tariff on clinker is the first such change in a decade. Cement producers have reacted, predictably, in a negative manner. Whether the authorities go ahead with the planned increase and how well the cement sector could absorb it remains to be seen. There may never be a good time for a tax rise but the BCMA has been able to present the current period as being especially bad.

India: Ambuja Cements has placed orders with equipment suppliers for an 8Mt/yr clinker capacity expansion across two of its cement plants. The plants in question are the 2.9Mt/yr Bhatapara cement plant in Chhattisgarh and the 4.5Mt/yr Maratha cement plant in Maharashtra. Ambuja Cements will also build 42MW-worth of waste heat recovery (WHR) power capacity. The new cement capacity will be able to operate on renewable energy and use 50% alternative fuel (AF). As such, upon completion of the project, the plants will together produce 14Mt/yr of Ambuja Cements' reduced-CO₂ Blended Green Cement. The producer will fund the work through internal accruals, and expects to complete it in May 2025.

CEO Ajay Kapur said "These brownfield expansion projects are part of our strategy to double our production capacity over the next five years from the current capacity of 67.5Mt/yr. Our ongoing investments in capacity expansion and sustainability will enable us to achieve our long-term objectives, as we remain committed to delivering sustainable growth and value to our stakeholders."

US: Holcim subsidiary Geocycle has signed a multi-year contract with Louisville Gas and Electric and Kentucky Utilities to market fly ash produced by the power generation companies. Geocycle and Holcim will use to up to around 225,000t/yr of fly ash to produce blended cement products.

Sophie Wu, Head of Geocycle North America, said “In line with Geocycle’s commitment and passion for recycling and achieving a net zero future, we are honoured to partner with Louisville Gas and Electric and Kentucky Utilities to develop creative and efficient solutions that contribute to the circular economy.” She added, “Together we’ll be able develop blended cementitious materials, reduce CO₂ levels and further encourage carbon neutral construction.”

Canada: Lafarge Canada’s Brookfield plant in Nova Scotia has switched to Portland Limestone Cement (PLC) production. The unit will now manufacture the company’s OneCem PLC product. It is the cement producer’s third plant to transition to PLC production in 2022 following the Bath plant in Ontario and the Richmond plant in British Colombia.

Andrew Stewart, the Vice President of Cement at Lafarge Canada (East), said, “We have been steadily moving the needle forward when it comes to cement decarbonisation and we will continue to honour our commitment in progressing our greener portfolio in Eastern Canada over the coming years.”

Philippines: The Department of Trade and Industry (DTI) has decided to impose anti-dumping duties on cement imported from Vietnam. Trade Secretary Alfredo E Pascual said that the dumping of Ordinary Portland Cement (OPC) and Blended Cement from Vietnam posed an "imminent threat of material injury to the domestic cement industry," according to the BusinessWorld newspaper. The duties will comprise 4 – 28% of the export price of OPC and 3 – 55% of the price of Blended Cement. The DTI has identified 11 cement companies from Vietnam that will be targeted with the anti-dumping tariffs.

A report by the Tariff Commission found that 53% of the total cement imported from July 2019 to December 2020 comprised product originating from Vietnam at dumped prices. Overall the country’s OPC and Blended Cement imports rose by 11% year-on-year to 5.90Mt in 2020 and by 16.2% to 6.85Mt in 2021. Imports rose by a further 7% year-on-year to 3.50Mt in the first half of 2022 compared to an average of 3.27Mt for the same half-year periods in 2019, 2020 and 2021. The TC said, "The existence of threat of material injury to the domestic industry is imminent in the near future, as indicated by the significant rate of increase of dumped imports into the Philippines capturing substantial market share, presence of price undercutting, price depression and price suppression.”

Philippines: The Tariff Commission (TC) has ordered that new duties be applied to imported Vietnamese cement for a five-year period up to 2027. The Department of Trade and Industry concluded a dumping investigation into Vietnamese cement exports to the Philippines in mid-October 2022, according to the Manila Bulletin newspaper. It found that imports of ordinary Portland cement (OPC) and blended cement from Vietnam were not injurious to the domestic cement sector at present. However, it also found the threat of material injury to be 'imminent.' This is due to Vietnam's 'substantial' cement overcapacity, which may enable it to rapidly increase its exports. The conclusion provided the basis for the TC's latest order.

Any new duty will replace provisional 2.7 - 32% duties introduced in December 2021. Previously, strong competition reportedly prevented the measures from causing price rises. Commentators now predict that the TC's proposed measures will result in a rise in prices.

India: JK Cement’s consolidated sales were US$272m in the first quarter of its 2023 financial year, up by 33% year-on-year from US$205m. The company sold 3.56Mt of cement, up by 18% from 3.02Mt in the first quarter of the 2022 financial year. Its costs per tonne rose to US$62.32/t from US$51.32/t. This restricted the group’s earnings before interest, taxation, depreciation and amortisation (EBITDA) growth to 0.1% year-on-year, at US$50.3m, compared to US$50.2m one year previously.

JK Cement forecast 10% year-on-year cement volumes growth in the 2023 financial year as a whole. It said that it expects to accelerate its rate of sales growth from September 2022. Its focus throughout the financial year will be on capturing new markets and increasing its blended cement share.

US: Lehigh Hanson’s Lehigh Cement plant in Union Bridge, Maryland plans to fully switch from Ordinary Portland Cement (OPC) to Portland limestone cement (PLC) production by January 2023. It will manufacture its EcoCemPLC product. The company says that the Union Bridge plant is currently the company’s largest cement plant in North America.

The decision to move to PLC follows similar changes at the company’s Mason City plant in Iowa and three cement plants in Indiana. Lehigh Hanson produced over 2Mt of PLC in 2021 and it says it is set to double this figure in 2022.

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.
