Taiwan: Asia Cement Corporation tested its waste wind turbine blade processing capacities using 12t of blades earlier in November 2023. The cement producer had previously processed 9t of waste turbine blades for use in its plants up to the end of October 2023. Asia Cement Corporation says that the waste consists of fibre-reinforced plastic (FRP), which is 60% silicon dioxide, calcium oxide and aluminium oxide and 40% polyester. The polyester can replace fossil fuels as alternative fuel (AF) for cement plants, while the other chemical compounds can serve as supplementary cementitious materials (SCMs).
Aggregate Industries to use waste tiles as alternative raw material
24 November 2023UK: Thousands of tonnes of waste ceramics from one of the UK’s largest ceramic tile manufacturers will be recycled to make cement as part of a new initiative from Aggregate Industries. The cement producer, owned by Holcim, has agreed a four-year deal with Johnson Tiles to take 20,000t/yr of legacy waste scrap from its Stoke factory in Staffordshire. They will be transported a short distance to Aggregate Industries’ Cauldon cement plant, where they will be crushed and mixed with limestone and the other raw materials prior to entering the kiln.
Andrew Whyatt, Geocycle UK General Manager at Aggregate Industries, said “We are delighted to be working with such a potteries stalwart as Johnson Tiles in order to recycle what would otherwise be a waste product. Materials such as this offer a great alternative to excavating fresh raw materials, preserving our local natural resources, whilst offering a solution whereby 100% of the material will be upcycled into new local cement. Both companies share a drive towards sustainable manufacturing and partnerships like this are vital as Aggregate Industries aims to reclaim or recycle 3Mt/yr of materials by 2025.”
France: Lafarge France has ignited the new kiln at its Martres-Tolosane cement plant following a Euro120m upgrade. Local press has reported that the upgrade replaced the plant’s existing kilns and preheater tower with entirely new equipment. The new kiln has tripled the plant’s capacity, to 2.1Mt/yr from 0.7Mt/yr. Meanwhile, the new preheater tower will help to reduce the plant’s electricity consumption by over 20%. As a result of the upgrade, the Martres-Tolosane plant can now support an alternative fuels (AF) substitution rate of 60%, compared to 20% beforehand. Lafarge France aims to carry out further work to reach 85% AF substitution at the plant by 2027. Other planned projects include the installation of a carbon capture system.
Lafarge France chief executive officer François Petry said “We are going to create a research and innovation centre here dedicated to the capture of CO2, with the ambition of ultimately making the Martres-Tolosane plant net zero carbon.”
US: Summit Materials has entered into a memorandum of understanding (MOU) with hydrogen producer PCC Hydrogen (PCCH2). The MOU establishes an alliance to develop a fuel replacement strategy for Summit Materials’ cement production. PCCH2 will build a hydrogen plant to supply green hydrogen at a cement plant belonging to Summit Materials subsidiary Continental Cement.
Continental Cement president David Loomes said "Continental Cement has a longstanding commitment to environmental stewardship, seeking out opportunities to develop innovative practices and differentiated solutions to build a better tomorrow. Our company has signed on to the Portland Cement Association (PCA)'s Roadmap to Carbon Neutrality, with a goal of achieving carbon neutrality across the value chain by 2050. By coupling PCCH2's hydrogen production process with our cement manufacturing know-how, we are taking a bold stride towards achieving that goal, while continuing the push to cost-effective decarbonisation of cement manufacturing."
Holcim España upgrades Carboneras cement plant to achieve 70% alternative fuel substitution rate
23 October 2023Spain: Holcim España invested Euro4m in an upgrade to its 1.5Mt/yr Carboneras cement plant in Almería. Alimarket-Construction News has reported that the upgrade will raise the plant’s alternative fuel (AF) substitution rate to 70% and enable it to dispose of 50,000t/yr of waste through co-processing it as AF. Holcim España expects this to reduce its CO2 emissions by 22,000t/yr.
Zlatna Panega Cement to upgrade Zlatnopanegki cement plant
16 October 2023Bulgaria: Titan Cement subsidiary Zlatna Panega Cement plans to invest Euro11m in sustainability-enhancing upgrades to its Zlatnopanegki cement plant in Lovech Province. The work centres around a Euro7m alternative fuels (AF) upgrade, to raise the plant’s AF substitution rate to 70% from 50% in 2022. Besides this, the producer will also invest Euro4m in the construction of a solar power plant at the facility. The solar power plant is scheduled for commissioning in March 2024. General manager Adamantios Frantzis said that the plant will subsequently move on to its ‘next big project,’ consisting of a Euro35 – 50m upgrade, in 2026 – 2028.
Zlatna Panega Cement invested Euro5.7m in capital expenditure throughout 2022, more than double its investments of Euro2.6m in 2021. It is committed to interim CO2 reduction targets of 5000t/yr (Scope 1) and 3000t/yr (Scope 2 and 3), and net zero CO2 emissions by 2050.
Cement producers of the Caribbean
20 September 2023The core of the Caribbean cement industry consists of the Dominican Republic (with 5.9Mt/yr in integrated capacity), Cuba (4.7Mt/yr) and Jamaica (3.5Mt/yr). Haiti and Trinidad & Tobago also command small, single integrated plants, while there are numerous grinding plants and cement terminals along the region’s extensive coastlines. The industry has been the subject of new commercial and capital expenditure-related announcements in the past fortnight. Regarding the Caribbean’s cement producers, these developments seem to lack a single clear direction.
Caribbean market leader Cemex revealed that it was considering selling up in the region’s largest market, the Dominican Republic, on 1 September 2023. Bloomberg cited unnamed sources stating that the Mexico-based cement giant hired financial services JPMorgan Chase to explore the possible divestment of local subsidiary Cemex Dominicana. Exactly one year had passed since Cemex completed its sale of Cemex Costa Rica and Cemex El Salvador to Guatemala-based Cementos Progreso for US$329m. Sources clued in on the latest development reportedly expect Cemex Dominicana to command a selling price three times greater than the Central American divestments combined.
Cemex has discussed its scattered disposal of global assets since 2019 as a strategic realignment towards its main markets, in particular those in North America and Europe. On this understanding, the Caribbean straddles an invisible line between Cemex’s strategic core in North America and Central America on its periphery.
Just to the north of the line lies Jamaica. There, Cemex subsidiary Caribbean Cement will expand its Rockfort cement plant by 30% to 1.3Mt/yr through a US$40m upgrade, scheduled for completion in early 2025. Late last week, Caribbean Cement told investors that the upgrade will equip the plant with new equipment, including a new dosing system. The producer expects this to help the Rockfort plant to further increase its alternative fuel (AF) substitution rate. It co-processed 5.6% AF in its kiln during the first half of 2023, more than double its first-half 2022 substitution rate of 2.7%. Caribbean Cement began exporting cement to Turks and Caicos on 16 September 2023, and plans to increase its shipments there and elsewhere. Managing director Yago Castro reassured Jamaicans that Caribbean Cement would also continue to help meet domestic demand.
Currently, Caribbean Cement and fellow Jamaican producer Cement Jamaica compete in the domestic market against imports, including some cement from Dominican Republic-based Domicem. This enters the country via Buying House Cement’s Montego Bay terminal. Montego Bay Cold Storage, an affiliate of Buying House Cement, shared plans for a second, US$8m cement terminal in the city earlier in 2023. The facility is expected to help meet growing demand from residential and hospitality sector construction.
More new production capacity is soon to come online in the form of a 1.23Mt/yr grinding plant in the Dominican Republic. Cemento PANAM will own and operate the plant, while Germany-based Gebr. Pfeiffer will supply a 3750 C-4 vertical roller mill via engineering, procurement and construction contractor CBMI Construction.
In a market where the nearest cement exporter is only a short sail over the horizon, producers have to compete fiercely for their market shares, even at home. Disputes over Caribbean Community member states’ rights to protect domestic cement production have gone as high as the Caribbean Court of Justice. It ended Barbados-based Rock Hard Cement’s hopes of resuming exports to Trinidad & Tobago last year.
The Caribbean’s cement producers will be acutely aware of Cementos Argos’ planned expansion of its north-facing Cartagena, Colombia, cement export facility, hot on the heels of a previous, US$42m expansion. The South American giant says that it is targeting the US, where it anticipates an upcoming construction boom. Caribbean countries present other possible markets for producers like Cementos Argos, yet their cement industries might equally emulate any successes it enjoys in the US. Like Argos in Colombia, Jamaica’s Caribbean Cement is part of a group with an existing presence in the US. Its on-going investments in the Rockfort plant signal a readiness to catch the trade winds rapidly picking up in the Caribbean.
ACC fires kiln at new Ametha cement plant
14 September 2023India: Adani Group subsidiary ACC has started commercial clinker production from the kiln of its new Ametha cement plant in Madhya Pradesh’s Katni District. BQ Prime News has reported that the kiln line has a clinker capacity of 3.3Mt/yr. It is capable of co-processing up to 15% alternative fuel (AF). The plant is also equipped with a 1Mt/yr grinding unit and a 16.3MW waste heat recovery (WHR) plant.
The Ametha cement plant raises ACC’s installed cement and clinker capacity by 9.8% to 37Mt/yr.
Dangote Cement to raise alternative fuel substitution rate to 25%
13 September 2023Nigeria: Dangote Cement plans to raise its alternative fuel (AF) substitution rate across its Nigerian operations to 25%. The Punch newspaper has reported that the producer consumed 34,800t of AF during the first half of 2023.
Obajana cement plant head of sustainability Eseosa Ighile said “We are working towards installing AF feeding systems in all our operation lines by 2024.”
India: Heidelberg Materials subsidiary Zuari Cement has commissioned a 20t/hr alternative fuel (AF) production line at its 7.1Mt/yr Yerraguntla cement plant. The line includes an UNTHA XR3000C shredder. This will support continuous operations and turn waste to AF in a single step, according to Zuari Cement.
HeidelbergCement India technical director Vimal Jain said “We are passionate about driving environmental progress throughout our business, and the use of AF is one way to do that. But this waste-to-energy feedstock comes at a cost, which is why co-processing makes so much sense. When designing this plant, we needed to ensure versatility to allow for changing market conditions, and an investment in technology that makes commercial sense and is built to last.”
