Georgia: Hunnewell Cement, a subsidiary of HeidelbergCement Georgia, has launched a new project to use tyres as an alternative fuel at its Kaspi cement plant, with support from the Georgian government. The project has a budget of US$2.1m, and is expected to create additional job opportunities. It marks a shift from the use of coal and natural gas at the plant, to ‘significantly’ reduce environmental impact and contribute to sustainable development.

Economy minister Levan Davitashvili said "Our goal is to minimise environmental pollution from ‘waste’ while promoting economic development and creating added value.”

Energy has been the theme for a couple of cement news stories of note from Egypt this week. The first concerns the government’s impending plan to centralise distribution of mazut (heavy fuel oil) to cement plants to help them cope with ongoing power shortages. Earlier in the week Cemex signed a deal with the Assiut Governorate to operate a second municipal solid refuse processing unit in the country. The company’s first Regenera facility, in Mahala, started operations in May 2024. Another story from mid-September 2024, along the same theme, covered the inauguration of an 18MW waste heat recovery (WHR) unit at Heidelberg Materials Egypt's Helwan Cement plant.

The wider story is that the country has faced so-called load shedding, or power rationing, since mid-2023 due to falling gas production, rising energy demand and negative currency exchange effects making it harder to buy fuel imports. The power cuts were extended in duration in July 2024 due to a heat wave. The government then said in late September 2024 that it is making investments to prevent domestic power cuts in 2025.

The cement stories mentioned above show some of the ways cement companies cut their energy costs. Two potential ways of doing this are to increase the use of alternative fuels (AF), such as municipal solid waste, or to install a WHR unit. Titan Cement, for example, reported AF thermal substitution rates of above 40% in Alexandria and above 30% in Beni Suef in the first half of 2024. The local press hasn’t reported power shortages amongst the country’s cement producers, but the plans to control the distribution of mazut suggest that either ‘something’ has happened or the government is trying to avoid ‘something.’ Readers may recall that producers have periodically faced step changes in power supplies over the years. In the mid-2010s, for example, lots of plants switched from heavy fuel oil and gas to coal. The energy price fluctuations following the start of the Russia - Ukraine war in 2022 then saw the price of coal rise.

However, what the foreign-owned producers have complained about in the first half of 2024 is the declining exchange rate of the Egyptian Pound. Cementir, Cemex and Titan Cement all noted this. However, Titan reckoned that International Monetary Fund and European Union investment had actually eased the economic situation in the first half of the year leading to an increase in the number of large construction projects.

One effect of the currency problems upon the cement market has been a focus on exports. At the start of September 2024 the Federation of Egyptian Industries said that national cement consumption in 2024 was expected to drop by 4% year-on-year to 45Mt. However, exports were projected to rise to 15Mt. The first and second most popular destinations so far in 2024 have been the Ivory Coast and Ghana. Yet, exports to Libya, the third biggest external market, may have had the biggest effect. These have been blamed for creating a shortage of trucks that was causing delays to the local construction sector. The round-journey from Egypt to Libya can take up to 12 days. This has left building sites bereft of raw material deliveries because all the trucks are elsewhere! Vicat acknowledged the growing importance of imports for its business in Egypt in its half-year report for 2024. It said that ‘sluggish’ domestic market conditions “were more than offset by growth in cement and clinker volumes for export to the Mediterranean and Africa regions.”

The wider picture of the cement sector in Egypt remains one of overcapacity with integrated capacity estimated above 70Mt/yr. The government introduced cement production quotas in mid-2021 and this stabilised prices (and profits). The recent state of the local economy may have strained this, but the latest round of external investment appears to have buoyed things for now. Although the effects of the Israeli military action in Lebanon may have unforeseen consequences upon neighbouring markets. In the meantime, cutting energy costs and growing exports offer two ways for producers to raise their profits.

Egypt: Cemex has signed an agreement with Assiut Governorate to operate its second Regenera facility in Egypt. This facility processes about 7,000t/month of municipal solid refuse, treating it to generate alternative fuels before compost production, thereby ensuring minimal residual materials go to landfill. The Assiut agreement follows the first Regenera facility in Mahala, which began operations in May 2024. Cemex has invested over US$2.5m in an alternative fuel dryer at the Assiut plant.

US: Colorado-based energy company NovoHydrogen plans to establish a hydrogen production facility at the Ash Grove Cement plant near Durkee, Oregon. Funded by the 2021 federal Bipartisan Infrastructure Act, the plant aims to start producing hydrogen fuel by 2028, according to CEO and founder Matt McMonagle. The hydrogen produced would be stored at the plant to be used to fuel trucks and other vehicles on-site, as well as potentially being used to power the plant. The construction of the plant will reportedly create 50 jobs.

Phillip Teintze, manager at the Durkee plant, said "The Ash Grove Cement Durkee plant is active in many opportunities to decarbonise our industry. Solutions for low carbon cement manufacturing are significantly challenging in terms of processes and expense. The Durkee plant is excited to see the development of NovoHydrogen’s efforts with the Department of Energy’s Pacific Northwest Hydrogen Hub. As hydrogen becomes environmentally and economically viable, we believe our facility could act as a distribution site, and potentially utilise hydrogen as a fuel to displace traditional fossil fuels.”

Egypt: Cemex has won a place on Fortune's 2024 Change the World list for its sustainable business practices. This recognition, the fourth for Cemex, highlights its collaboration with VeryNile to clean the Nile River and develop sustainable solutions for discarded materials. Supported by the Ministry of the Environment, VeryNile focuses on removing inorganic matter from the Nile, upcycling plastics, and converting non-recyclable materials into alternative fuel for Cemex's Assiut cement plant. This initiative not only reduces pollution but also improves water quality for the local community and provides alternative employment for 150 local fishermen and women affected by contamination of the Nile.

CEO of Cemex Fernando González said "We are once again honoured by Fortune's recognition of our sustainable business model, which aligns environmental conservation with social empowerment. The VeryNile initiative exemplifies how companies can collaborate with NGOs and society to change the world for the better."

Bolivia: The Viacha cement plant, operated by Sociedad Boliviana de Cemento (Soboce), has launched a pilot to co-process discarded electrical and electronic equipment into alternative fuels. This initiative, developed in coordination with the Ministry of Environment and Water, involves the management of 133t of materials. The process includes converting discarded plastics with brominated flame retardants into energy for the plant.

CEO of Soboce, Francisco Shwortshik, said "Viacha has all the licenses and environmental authorisations for the co-processing of alternative fuels. Today we are witnessing a historic milestone for the industry, because it marks the beginning of the era of alternative fuels, as a sustainable environmental solution for the country."

Canada: Geocycle and Lafarge Canada, together with the Department of Natural Resources Canada, have opened a new low-carbon fuel plant at the Lafarge Canada Brookfield cement plant in Nova Scotia. The facility, which cost over US$7.5m and received US$2.6m in federal funding, will convert 14,000t/yr of discarded materials headed for landfill into low-carbon fuels, reducing the plant's reliance on fossil fuels and its carbon emissions by over 12,000t/yr. The materials to be repurposed include plastic and construction and demolition materials. The cement created at the facility will be used to make concrete for construction projects in the local area and is expected to create jobs for the local community.

President and CEO of Lafarge Canada (East) David Redfern said "Cement is a vital component of infrastructure projects that contribute to economic growth. By implementing sustainable and innovative solutions to reduce our environmental impact, we're serving the needs of our customers and the communities in which we operate both now and in the future. Our continued collaboration with Geocycle Canada reinforces our commitment to invest and advance circular construction in Canada."

Head of Geocycle North America Sophie Wu said "At Geocycle, our solutions are circular by design. We are happy to take another significant step in our ongoing partnership with Lafarge Canada. This is a great example of our work toward the decarbonisation of the construction industry in Canada."

One surprise at the end of August 2024 was that Türkiye-based Çimsa has agreed to buy a majority stake in Ireland-based Mannok. The subsidiary of Sabancı Holding signed a deal to acquire just under a 95% stake in Mannok Holdings based on an enterprise value of Euro330m for 100% of the shares. The final purchase price will be determined later in the process, as will a potential completion date subject to the usual regulatory approvals.

Çimsa has described the deal as its “third major global initiative in the past three years” following expansions in the US and Spain. Çimsa started production at its 0.3Mt/yr white cement grinding plant in Houston, Texas in 2019. It is currently planning to set-up a 0.6Mt/yr grey cement grinding plant, also in Houston, with operation expected to start by the end of 2024. Its Spain-based business received a boost in mid-2021 when it purchased the Buñol white cement plant in Valencia from Cemex. Outside of Türkiye the company also operates a few terminals in Germany and Italy. Of interest to this article it established a subsidiary for sales in the UK in mid-2023.

Mannok was previously known as Quinn Group before it was rebranded in 2020. In addition to cement the company sells a range of construction products including PIR (polyisocyanurate) insulation, aircrete thermal blocks, roof tiles and precast concrete. The company is headquartered at Derrylin in Fermanagh, Northern Ireland in the UK but it operates in both Ireland and the UK. It runs a 1.4Mt/yr integrated plant at Ballyconnell, County Cavan in Ireland, just across the border from Derrylin. With the 17th Global CemFuels Conference scheduled to take place next week in Dublin, it is worth noting that this cement plant had a recent upgrade of interest to the alternative fuels sector. In 2023 the company said that it had installed the world’s first FLSmidth Fuelflex Pyrolyzer at a cement plant following an earlier pilot of the system back in 2018. It is used to replace coal with solid recovered fuels (SRF) in the pre-calcination stage of cement production. Later in 2023 Mannok said that the equipment was reducing its CO₂ emissions by 58,000t/yr.

As reported in the October 2023 issue of Global Cement Magazine, cement from the Ballyconnell plant is sold in both Ireland and the UK. In 2022, 35% of its sales were in Ireland, 30% in Northern Ireland and the remaining 35% in the rest of the UK. The company uses a storage unit at Warrenport in Northern Ireland to despatch cement to a 8400t cement storage and distribution at Rochester in Southern England.

Çimsa said that the acquisition is intended to help it to increase the share of its revenue in foreign currencies to over 70%. It is not a revelation that Çimsa might want to do this given the parlous state of the economy in Türkiye since 2018. Interest rates are high and the Turkish Lira has lost value. Çimsa raised the issues this has caused in its 2023 annual report. These include higher costs for imported goods and services such as energy, equipment and engineering services. In 2023 the company reported that 57% of its sales consisted of foreign currency-based revenue. The same year exports represented just under 40% of the company’s total revenue. Overall, Çimsa’s revenue fell slightly year-on-year in 2023, in part due to the divestment of a cement plant and other assets, but earnings rose significantly.

Buying Mannok gives Çimsa another route into the European Union (EU), via Ireland, and the UK. Crucially, this gives its first integrated grey cement production site outside of Türkiye. Both of these things are especially useful for an export-focused company facing increasing hurdles to sales in the guise of the EU Emissions Trading Scheme. It also helps the business to further hedge against negative currency exchange effects back home in Türkiye. So ‘Sláinte’ to Çimsa and Mannok, and good luck.

The 17th Global CemFuels Conference & Exhibition takes place in Dublin, Ireland on 18 - 19 September 2024

Canada: Ash Grove Mississauga cement plant has entered a proposal with the Ministry of Environment Conservation and Parks to burn alternative fuels. This includes materials such as construction and demolition materials, paper fibre, wood, plastic and industrial rubber, according to the Insauga newspaper. Local residents have expressed concerns about potential toxicity and environmental impacts due to emissions from the plant entering the atmosphere. The association reportedly objected to a previous application allowing higher emissions levels at the plant. Ash Grove will address these concerns in a public meeting scheduled for 12 September 2024.

Spain: Votorantim Cimentos will construct a solid recovered fuel (SRF) production plant at its subsidiary Cementos Cosmos’ plant in Oural, aiming to produce up to 0.15Mt/yr of alternative fuel, reports Digital Economia newspaper. The facility, spanning 5800m², will utilise non-recyclable industrial byproducts and various discarded materials from the local community such as plastic, paper and wood, to partially fuel the combustion in its cement kilns. The plant, currently in the public exhibition phase, will start production at 60% capacity, producing 85,000t/yr of alternative fuel. Plans include ramping up to full capacity to produce roughly 0.15Mt/yr. The new plant will create 15 jobs.

Votorantim Cimentos has not detailed the investment in the new facility, although the budget presented to the local council amounts to €12m.
