Update on Egypt, April 2022

13 April 2022

Vicat’s plans to buy another 42% stake in Sinai Cement became public this week. Once completed, the France-based company should own 98% of the Egyptian company, based on previously published ownership figures. The announcement heralds a rapprochement in the relationship between the cement producer and the Egyptian government.

Last year Vicat raised a case against the government with the International Centre for Settlement of Investment Disputes (ICSID) over an argument about how it could invest in Sinai Cement as a foreign company. All seems forgiven and forgotten now with a settlement agreement signed in March 2022 between Rania el Mashat, the Minister of International Cooperation on behalf of the Egyptian government, and Guy Sidos, the chairman and chief executive officer of Vicat Group. Local press reported that the government is trying to attract more direct foreign investment. Sinai Cement reported a loss attributable to its parent company of around US$19.1m in 2021, down from a loss of US$30.3m in 2020. However, its sales rose by 63% year-on-year to US$78m.

Sinai Cement has some specific operating issues related to its geographic position in the Sinai Peninsula and ongoing security concerns. Yet its mixed fortunes also sum up some of the continuing challenges the Egyptian cement industry is facing. After years of overcapacity, the government introduced reduced cement production quotas in July 2021 and this is mostly perceived to have improved prices in the second half of the year. Vicat described the arrangement as having capped the local market at 65% of its production capacity and it said that prices recovered ‘significantly’ as a result in the second half of 2021. Cemex’s regional chief Carlos Gonzalez told local press that the move had given plants “A glimmer of hope for the return of balance to the cement market.” The company has also announced a US$20m local investment backing up this view. Not all the foreign multinational companies entirely agreed, with HeidelbergCement reporting a ‘sharp’ decline in sales volumes although chief executive officer Dominik von Achten did describe the country as ‘coming back’ in an earnings call about his company’s financial results in 2021. Solomon Baumgartner Aviles, the chief executive officer of Lafarge Egypt, was also cooler about the production cap in a press interview in October 2021, describing it as too early to assess how well the cap was working and noting that the gap between supply and demand was still large.

Vicat said in its annual report for 2021 that, “Provided no further adverse geopolitical, health or security developments occur, the current climate is unlikely to jeopardise the prospects of an improvement in the subsidiary’s profitability, which should begin to gradually occur.” The geopolitical bit was timely given that Russia’s war in Ukraine started on 24 February 2022. It also targets the latest problem hitting Egyptian cement producers: energy costs. The head of Arabian Cement told Enterprise Press that initially some producers had opted to temporarily stop production and use stocks instead to attempt to try and wait until the energy price volatility ended. However, it stayed high so the cost of cement has gone up generally. Producers are now trying to switch to using a high ratio of natural gas, such as 10%, but this is dependent on the government letting them.

The Egyptian government, for its part, is facing a decision whether to supply subsidised gas for domestic industry or to export to Europe. The backstory here is that Egyptian cement producers are facing yet another step change in fuel supply. In the mid-2010s lots of plants switched from heavy fuel oil and gas to coal. High international coal prices could be heralding another change.

Alongside this the value of Egypt’s cement exports rose by 151% year-on-year to US$456m in 2021 from US$182m in 2020. The Cement Division of the Federation of Egyptian Industries has attributed this to growth mainly on the African market. This trend continued in January and February 2022 with cement exports up by 141% year-on-year to US$104m from US$43m. The main destinations were Ghana, Cameroon, Ivory Coast and Libya.

HeidelbergCement summed up the current state of the Egyptian cement market in its 2021 annual report as follows “The development of the Egyptian cement market continues to be determined by government intervention.” What happens next is very much in the hands of the state as it decides whether to extend the production cap, which fuels to subsidise, whether to allow exports and where to invest in infrastructure projects. One variation on this theme may be local decarbonisation targets. At the end of March 2022 the Global Cement and Concrete Association (GCCA) launched a series of Net Zero Accelerator initiatives, including one in Egypt. How a country that produces more cement than it needs reduces its CO2 emissions presents another challenge for manufacturers and the government to grapple with.

Financing revealed for Power Cement’s solar project

13 April 2022

Pakistan: Meezan Bank, an Islamic bank, and Burj Solar Energy (BSE) have announced the completion of a US$5m syndicated Islamic finance facility for BSE's portfolio of renewable distributed power generation in Pakistan.

A first tranche of US$3.2m will be used to finance the construction of a 7MW solar power plant for Power Cement on the Karachi-Hyderabad Motorway. The solar power plant will be rented to Power Cement under a 20-year equipment rental agreement to supply the company's cement plant in Nooriabad. It will generate 220GWh solar units for 20 years and, in addition to reducing cost of electricity, will offset 112,000t of CO2 emissions. The project is expected to start generating power in July 2022.

Intergovernmental Panel on Climate Change report calls on cement industry to promote use of secondary cementitious materials and encourage carbon capture

07 April 2022

Switzerland: The latest report from the Intergovernmental Panel on Climate Change (IPCC) has informed policymakers that the best current route to reduce carbon emissions from cement production is through the increased use secondary cementitious materials and by encouraging the development and uptake of carbon capture. Alternatively, the development of new chemistries for building materials could help the situation but this is not expected in the short to medium term.

The report noted that 12Gt of CO2 equivalent was released directly and indirectly in 2019 from buildings and emissions from cement and steel use for building construction and renovation. These emissions included indirect emissions from offsite generation of electricity and heat, direct emissions produced onsite and emissions from cement and steel used for building construction and renovation. In sections of the IPCC report yet to be finally approved the authors said, “Cement and concrete are currently overused because they are inexpensive, durable, and ubiquitous, and consumption decisions typically do not give weight to their production emissions.”

Overall, the report concluded that average annual global greenhouse gas emissions from 2010 to 2019 were at their highest levels in human history but the rate of growth had slowed. The IPCC has called on “immediate and deep emissions reductions across all sectors” for any chance for society to limit global warming to 1.5°C. To do this global greenhouse gas emissions would have to peak before 2025 at the latest and be reduced by 43% by 2030. However, even if this did occur, it would take until the end of the 21st century for the temperature threshold to be stabilised.

Calcined clay projects in Africa

06 April 2022

African cement producers have confirmed their interest in calcined clay over the last month with two new projects. The big one was announced last week when FLSmidth revealed that it had received an order from CBI Ghana. This follows the launch of a Limestone Calcined Clay (LC3) project in Malawi in mid-March 2022 in conjunction with Lafarge Cement Malawi.

FLSmidth says that its order includes the world’s largest gas suspension calciner system and a complete grinding station. The kit will be installed at CBI Ghana’s plant near Accra in the south of the country. The new clay calciner system is expected to substitute 30 - 40% of the clinker in the final product, resulting in a reduction of up to 40% CO2/t of blended cement compared to Ordinary Portland Cement (OPC). Overall the equipment manufacturers reckon that the grinding plant will reduce its CO2 emissions by 20% compared to its current output. There has been no indication of how much the order costs but CBI Ghana expects energy and fuel savings, as well as lower overheads from clinker imports.

The public announcement of the Ghana project was also foreshadowed by the visit of Professor Karen Scrivener to the Ghana Standards Authority in February 2022. This was significant because Scrivener is the head of the Laboratory of Construction Materials at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and has been one of the key instigators of the LC3 initiative since the early 2000s. Other calcined clay cements are available such as Futurecem or polysius activated clay (see below) but LC3 is arguably the most famous given its promotion in developing countries.

The Malawi project is at a much earlier stage. The government launched the public private partnership LC3 project in mid-March 2022 in conjunction with Lafarge Cement Malawi and Terrastone, a brick manufacturer. The Ministry of Mining is currently developing a memorandum of understanding with the Gesellschaft für Internationale Zusammenarbeit (GIZ), a Germany-based development agency. India-based Tara Engineering has also been linked to the scheme.

One thing to note about the Malawi project is that it is the first calcined clay project in the cement industry based in East Africa. All the other African ones are based in West Africa. The other two projects in this region are run by Turkey-based Oyak Çimento and its subsidiary Cimpor. The first of these is a 0.3Mt/yr calcined clay and a 2400t/day cement grinding production line that was commissioned in mid-2020. This plant is based at Abidjan in Ivory Coast. The second is a new plant that Germany-based ThyssenKrupp Industrial Solutions is building for Oyak Çimento at Kribi in Cameroon. This unit has a 720t/day calcined clay and a 2400t/day cement production capacity and it will use the supplier’s ‘polysius activated clay’ technology. ThyssenKrupp’s involvement came to light in early 2020 and commissioning was scheduled for late 2021. However, no update on the state of the project has been issued so far in 2022.

As the above examples show, Sub-Saharan Africa has at least one live calcined clay plant, two plants are being built and there’s one more at the development stage. This puts the region neck-and-neck with Europe, which has a similar mixture of current and developing projects. This column has been covering the wider trend of the growing usage of various types of blended cements recently, particularly in Europe and the US, with slag cements, Portland Limestone Cement (PLC) and more. With PLC, for example, note the transition of another two North American cement plants to PLC this week alone. As for calcined clay cement, it is fascinating to see the focus move to a different part of the world. Several commentators have predicted that the future looks set to be dominated by blended cements using whichever supplementary cementitious material (SCM) is most available for each plant. The growth in calcined clay confirms this view.

South Korean cement production to increase in second quarter of 2022

06 April 2022

South Korea: Seven cement producers have agreed to produce 3.77Mt of cement in the second quarter of 2022, up by 36% quarter-on-quarter from first-quarter 2022 levels, to alleviate a shortage. 380,000t of cement which would previously have been exported will now supply the domestic market instead. The Yonhap News Agency has reported that bituminous coal supply issues have hampered the domestic cement industry's ability to increase its production in line with demand growth. In the first quarter of 2022, South Korea's coal imports consisted of 54% Russian coal and 46% Australian coal, compared to 75% Russian and 25% Australian coal in 2021.

The government plans to invest US$764m between 2023 and 2030 in improving the sustainability of South Korean cement production, including moving it away from reliance on coal through increased alternative fuel use.

HeidelbergCement, Felleskjøpet AGRI and Egil Ulvan Rederi to build the world's first zero-emission bulk carrier

06 April 2022

Norway: HeidelbergCement, agricultural cooperative Felleskjøpet AGRI and shipping company Egil Ulvan Rederi plan to build what they say will be the world's first zero-emission bulk carrier. The project has also received support of around Euro12m from the Norwegian government-owned sustainability company Enova. The vessel is scheduled for completion and commissioning in 2024. Once operational the ship will be used to transport aggregates products for HeidelbergCement and grain for Felleskjøpet between west Norway and east Norway using hydrogen powered transport.

Egil Ulvan Rederi was selected following a tendering process in 2021. The ship is intended to be highly energy efficient, using rotor sails and has a streamlined design to reduce energy consumption. It will be powered by hydrogen from Norwegian energy supplier Statkraft but will also have small auxiliary batteries and a fuel cell on board to maximize flexibility.

Giv Brantenberg, general manager HeidelbergCement Northern Europe, said “The project addresses emissions from the transport part of our value chain. It is unique, ambitious and future-orientated. It is fully in line with HeidelbergCement Group's target to be the leading actor in our industry on the path to carbon neutrality." HeidelbergCement estimates that the carbon footprint of the aggregates products can be reduced by 50 - 60% by using the zero emission vessel, as transport accounts for a significant part of the total carbon footprint of these products.
