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.”

Oman: Oman's solid waste management entity, Be'ah, has reported progress in its strategy to transition solid waste from landfill disposal to refuse derived fuel (RDF), according to Oman Daily Observer.

In 2023, Be'ah launched initiatives focusing on transforming waste into RDF, electrical and electronic waste and green waste. The company has signed an agreement with Oman Cement Company to provide tyre derived fuel for its energy needs, eventually expanding to include RDF. A memorandum of understanding (MoU) was signed with Oman Cement during Oman Sustainability Week to explore the utilisation of RDF as an additional alternative fuel source, according to the company’s 2023 sustainability report.

Chair of Be’ah, Ahmed al Subhi, said "We take pride in our strategic resource management initiatives, having set ambitious targets for transitioning to a circular economy, including achieving 60% waste utilisation by 2025 and 80% by 2030.”

Mexico: The Secretariat of the Environment (Sedema) has reported that over 5600 tyres collected from illegal dumps in the districts of Xochimilco and Gustavo Madero have been transported to a treatment plant to be used as an alternative fuel for cement production. This initiative is part of a strategy to manage tyre waste, supported by a collaboration with Geocycle Mexico. The effort aims to address public environmental issues caused by tyre disposal in public spaces and environmentally sensitive areas, potentially leading to wildfires. Sedema also plans to expand tyre collection through the Reciclatrón Program to promote comprehensive waste management and reduce the reliance on fossil fuels and mineral extraction.

New Zealand: Golden Bay, New Zealand's sole cement producer and a division of Fletcher Building, is advancing its sustainability goals at its Portland plant near Whangārei. The plant has been incorporating old tyres and treated timber in its production process since 2021, with the Ministry for Environment helping fund US$10m of the US$15.5m to upgrade the plant for the project. The plant uses tyres to replace 55-60% of the coal required, and plans to eliminate coal use by 2030. The facility has increased its use of recycled tyres from 15,000t to 30,000t/yr and is aiming for 40,000t/yr. The government’s Tyrewise programme supports tyre recycling, with the plant also investing in an on-site shredder. Upcoming projects include substituting coal with non-recyclable materials like old carpets and plastics, targeting a 30% reduction in emissions. Construction has already started on the project and it is expected to be completed by the end of 2024, according to the New Zealand Herald.

Manufacturing manager Kelly Stevens said, "We’re diverting 100,000t/yr of waste that would’ve gone to landfill.”

Jamaica: Caribbean Cement is allocating US$8m, 20% of its planned US$40m investment in 2024, to increase sustainability efforts at its Rockfort plant. The company is aiming to become net-zero by increasing its use of alternative fuels and repurposing materials like tyres, which will also help to save on operational expenses and fuel costs, according to the company.

The repurposing of tyres, which commenced following a Government of Jamaica partnership, will remove a ‘significant’ portion of the estimated 1.5m tyres at the country’s Riverton dump, along with other materials such as pallets, which Caribbean Cement now uses as alternative fuel sources in the cement manufacturing process. With the help of its XRC3000c shredder obtained from Austria-based company UNTHA, Caribbean Cement said it has shredded more than 9000 tyres to date.

Managing director Jorge Martínez said “At the moment our first goal for the end of 2024 is to at least reach 10% alternative fuels. We will remove some of those fuels that are not renewable, substituting it with ones that are. This is part of our future in action programme. Some of these actions are also related to the reuse of some materials in the plant as we take waste materials from other industries and beach clean-ups for repurposing. We try to reuse them in any way we can.”

US: Holcim US has announced plans for a 25MW solar power plant to serve 75% of the electricity needs of its Alpena cement plant in Michigan. The company says that the installation at the Alpena plant will be the largest in the US Midwest Region. Holcim US chose NorthStar Clean Energy to build the array, which it says will eliminate 25,000t/yr of CO₂ emissions.

Other planned projects at the Alpena cement plant include an upgrade to the plant's dock in order to accommodate larger vessels and reduce the number of trips in its Great Lakes transport operations.

Holcim US' senior vice president, manufacturing, Michael Nixon said “As Holcim is showing in Alpena, the path to net-zero carbon emissions requires a blend of proactive solutions. Whether it’s using alternative fuels or implementing renewable energy from solar power, we are committed to reducing our reliance on fossil fuels — a goal that will benefit the environment as a whole and the Alpena community we have called home for more than 115 years.”

US: Holcim US has inaugurated a waste tyre processing plant at its Alpena cement plant in Michigan. The facility will process 22,000t/yr of tyres into refuse-derived fuel (RDF) for use at the cement plant. Holcim US partner Geocycle will collect, pre-process and deliver the tyres to the new facility.

Holcim US’ North regional senior vice president of manufacturing Michael Nixon said "Holcim has invested more than US$100m in eco-friendly technologies at the Alpena plant in the past 15 years. The tyre-derived fuel facility is another strong demonstration of our commitment to reducing emissions."

New Zealand: Golden Bay Cement has signed a deal with Genesis Energy for a supply of bottom ash from Huntly power plant for use in cement production at its Portland cement plant in Northland. Genesis Energy generates 20,000t/yr of bottom ash at the Huntly plant, situated in Waikato, 260km south of the Portland cement plant. The plant currently uses 15,000t/yr of fly ash from the Huntly power plant in its operations. The producer was previously investigating the use of volcanic ash in cement production in 2022. It currently uses waste tyres and wood waste as alternative fuels (AF) to produce its EcoSure low-carbon general-purpose cement.

Golden Bay Cement's general manager Gian Raffainer said "We are driven to decarbonise and achieve 30% less carbon by 2030. Contributing to waste reduction at a large scale for the benefit of all New Zealanders is incredibly exciting. It is a win-win for the environment and for Kiwis who want to use more environmentally friendly products."

Huaxin 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.

Brazil: Secil Supremo Cimentos has appointed FLSmidth to carry out a pyro process upgrade at its Adrianópolis cement plant in Paraná. The Denmark-based supplier says that it plans to carry out modifications on the plant's preheater, cooler and related auxiliary equipment. It says the new equipment will expand the plant's capacity to 3900t/day, corresponding to an annual production capacity of 1.42Mt/yr. It will also enable it to increase its alternative fuel (AF) substitution rate to 40%. Secil Supremo Cimentos' AF mix consists of shredded tyres, wood and other refuse-derived fuels.

FLSmidth's head of capital sales, Jens Jonas Skov Larsen, said “We are grateful for our continued partnership with Supremo, which has consistently invested in the latest technology. As the plant was already operating an ILC five-stage preheater from FLSmidth, it was well positioned to use AF.”
