Ambuja Cements to expand clinker capacity by 8Mt/yr across Bhatapara and Maratha cement plants
12 May 2023India: 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."
India: Nuvoco Vistas’ sales rose by 14% year-on-year during the 2023 financial year, to US$1.29bn. The group’s cement sales volumes were 18.8Mt, up by 5%. It recorded a profit after tax of US$1.95bn.
In 2023, Nuvoco Vistas achieved a cement alternative fuel (AF) substitution rate of 12%. Its emphasis on developing blended cements enabled it to achieve an industry-leading cement to clinker factor of 55%. It operations during the year relied on over 20% renewable energy.
India: ACC has blamed a drop in earnings in the fourth quarter of its financial year on higher fuel prices. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 15% year-on-year to US$71.9m in the quarter that ended in March 2023 from US$64.7m in the same period in 2022. However, it said that fuel prices were expected to drop due to synergies with other subsidiaries within Adani Group. It is also working on reducing operational costs by reducing its clinker factor, logistics costs and growing sales of blended cement products. It added that it had reduced its kiln fuel cost by 10% in the fourth quarter by taking the measures mentioned above and by increasing its use of alternative fuels.
The company changed its financial year to one ending in March 2023 during the reporting period. Its calculated net revenue rose by 10% year-on-year to US$2.16bn for its 2023 financial year that ended on 31 March 2023 compared to US$1.97bn in the previous 12 months. Its cement and clinker sale volumes grew by 6% to 31Mt from 29Mt.
Ajay Kapur, the chief executive officer of ACC, said “Our transformation journey fuelled by sizeable operational efficiencies, improved synergies and business excellence has led to substantial improvement in our financial performance and overall business indicators. We have a detailed blueprint on each of the cost factors and initiatives to reduce and improve.”
Lithuania: Arturas Zaremba, the head of Akmenes Cementas, has warned that government proposals to increase the import tax on coal in 2024 and the abolition of subsidies for the fuel will affect the company. The country’s parliament is also proposing scaling the import tax based on a CO2 scale, according to the Baltic Business Daily newspaper. Zaremba said that the cement producer uses 130,000t/yr of coal. However, it is currently investing Euro22m on an upgrade to its Akmenes integrated plant to allow it to switch to using a higher proportion of solid-recovered fuel. It currently has a 10% alternative fuels substitution rate using dried sewage sludge and tyres.
Zaremba said "There will be some impact because we will still have some of that coal left, but not as much as we would have had without the investment. I have not followed how much they plan to increase the excise duty, but we need to look into how much that would be in the financial terms. Any increase has an impact."
France: Ciments Calcia has announced an investment of Euro86m to further decarbonise cement production at its integrated Beaucaire plant. The subsidiary of Germany-based Heidelberg Materials has allocated a total of Euro600m towards reducing CO2 emissions from all of its operations in the country in response to a government initiative, according to The Tribune newspaper.
The current funding follows a spend of just under Euro7m on upgrades at the site, including installing a new clinker cooler that will allow for greater recovery of waste heat, and the addition of a new computer control system. Following this work, the single production line plant was restarted in early April 2023.
The next stage of investment has started with a feasibility study. If successful, a tendering process could start in the second half of 2023 with work planned to start in 2025. The company intends to renovate the plant’s electricity network, modernise the production line with a preheater and a pre-crusher and make further changes to target an alternative fuels thermal substitution rate of 75%. A third stage, involving carbon capture and utilisation and/or storage, is tentatively planned to start in 2030.
Portugal: The first batch of clinker has been manufactured on the new upgraded production line at Secil’s Outão plant. Construction and start-up teams from ThyssenKrupp Polysius reached the milestone in mid-April 2023 after a heating period of 72 hours. Germany-based ThyssenKrupp Industrial Solutions was appointed by Secil to work on the Clean Cement Line project in 2020. It said it was going to modify the existing rotary kiln and preheater tower, install a new calciner and add a new grate cooler. Once finished it will produce Portland limestone cement (PLC). It is scheduled for commissioning in mid-2023.
Italy-based CTP Team was contracted in mid-2020 to supply and install a 29MW waste heat recovery (WHR) unit for the project. It planned to use an organic rankine cycle (ORC) unit using a 7.2MW turbine supplied by Turboden.
Italy-based Bedeschi also revealed in early April 2023 that it was in the cold commissioning phase for a new pipe conveyor at the plant to handle different kinds of alternative fuels. The conveyor has a diameter of 250mm and conveying length of 350m and will transport alternative fuels at a rate of 300m3/hr.
Cemex Philippines halves CO2 emissions since 1990
18 April 2023Philippines: Cemex Philippines (CHP) says it has reduced the CO2 emissions from its subsidiaries, Solid Cement Corporation and APO Cement Corporation, by 50% between 1990 and 2022. From 2020 to 2022 CHP reduced its net CO2 emissions by 18%. The company claims this is the highest CO2 emissions reduction in the sector based on publicly released information.
Luis Franco, the president and chief executive officer of CHP, said "This milestone CO2 reduction was possible because of our team's high commitment to achieve net zero. We are on track to meet our ambition of less than 430kg of net CO2 per tonne of cement by 2030 and deliver net-zero CO2 concrete by 2050." He added that the company is confident it can reach a 67% reduction by 2030 through the continued used of alternative fuels and decarbonated raw materials.
Update on Oman, April 2023
12 April 2023Huaxin Cement completed its acquisition of a majority stake in Oman Cement this week. The China-based company estimated that the purchase price was around US$193m. Following the transaction with a subsidiary of the Oman Investment Authority, the country’s sovereign wealth fund, the cement producer now controls just under a 60% share in Oman Cement.
A key part of the deal includes Oman Cement’s integrated plant at Ruwi in the north of the country. The three-line unit has clinker and cement production capacities of 2.6Mt/yr and 3.6Mt/yr respectively. With the partial ownership share of 60% taken into account, this places the capacity purchase price at around US$124/t, a lower figure for capacity compared to other international acquisitions.
Oman Cement has a couple of new projects in the pipeline that have been mentioned on and off previously over the last year or so. These include the construction of a new 10,000t/day fourth production line, an upgrade to line 3 to 4000t/day from 3000t/day at present and plans for a new plant at the Special Economic Zone (SEZ) at Duqm. The company said it was looking for a contractor to carry out the upgrades at the Ruwi plant. However, Rashid bin Sultan al Hashmi, the chair of Oman Cement, said in the company’s annual results for 2022 that the Duqm project, operating under the name Al Sahawa Cement, had run into problems with the supply of gas for the proposed unit. Another recent development was the signing of a deal between Omani Environment Services Holding Company (Be’ah) and Oman Cement for the supply of refuse-derived fuel (RDF). As an aside, that last one may also have received a boost this week with the news that the local Environment Authority has suspended licenses for the export of used tyres from the country.
How these existing projects will fare under the new ownership remains to be seen, but Huaxin Cement has a track record for developing new cement production capacity outside of China. The cement producer describes itself as de-facto controlled by Switzerland-based Holcim although Holcim said in its annual report for 2022 that Huaxin Cement is a joint-venture. It currently operates plants in Cambodia, Kyrgyzstan, Malawi, Nepal, Tajikistan, Tanzania, Uzbekistan and Zambia and says that it has 10 additional projects in Africa, the Middle East and elsewhere in preparation for future business expansion. In 2022 it started operating a 3000t/day production line at Nepal Narayani and commenced the second stage of a project to build a 4000t/day clinker line at Maweni in Tanzania. Plus, as mentioned in our recent roundup of China-based producers, 13% of the group’s operating revenue derived from business outside of China in 2022 compared to 8% in 2021.
Other producers from outside of Oman have also been active locally in 2023. In late January 2023 India-based UltraTech Cement agreed a deal to buy a 70% stake in Duqm Cement Project International from Seven Seas for US$2.25m. The agreement covered a limestone mining lease that UltraTech Cement said was important for “raw material security.”
The other big development in the Oman cement market since we last covered the country in September 2021 was an intervention by the Capital Market Authority (CMA) on Raysut Cement. The chief financial officer resigned in November 2022 before the CMA questioned the company’s financial results for the second quarter of 2022. The CMA then replaced the board of Raysut Cement in December 2022 saying it had detected ‘material misrepresentation’ in the company’s third quarter results.
The last four months or so have marked a turning point for the local cement sector with a change in leadership for the two largest producers. Oman Cement reported strong growth in 2022 although it warned of “low priced cement being supplied by competitors.” Raysut Cement, unsurprisingly, recorded a loss in 2022. The construction market in the country is expected to grow as the economy leaves the coronavirus period behind, mounting energy prices boost national revenue and potentially some of this heads into infrastructure development. This puts the new management at both producers in a good position going forward.
