UK: The Cement 2 Zero project has successfully concluded its first trial melt of recovered cement paste in an electric arc furnace at the Materials Processing Institute’s Teesside campus. The project uses the paste as flux for electric steel recycling. Cambridge Electric Cement (CEC) has demonstrated that the ‘slag’ from this process can be ground into fine clinker that, when mixed with gypsum and supplementary cementitious materials (SCMs), produces net zero CO₂ cement. The Cement 2 Zero project to produce CEC’s cement at an industrial scale launched in March 2023, with US$7.85m in funding from UK Research and Innovation. Tarmac will grind the clinker from the project’s trial melts for testing in order to obtain certification and specification as a usable cement product.

UAE: Cemex UAE and UltraTech Cement UAE have signed an agreement to collaborate on the development of waste concrete recycling in the UAE, according to Dow Jones Institutional News. The cement producers say that their partnership will help to reduce CO₂ emissions from construction, in line with the UAE’s 2050 net zero commitment.

India: JSW Cement is conducting a pilot project in the use of electric vehicles for cement transportation. The producer has introduced five Murugappa electric cement trucks into its fleet in Andhra Pradesh and Karnataka. It expects these to eliminate 150t/yr of CO₂ emissions from its logistics operations.

Daijiworld News has reported that CEO Nilesh Narwekar said “The pilot project is an important milestone in making our future much greener and more purposeful.” He added “Based on the success of these pilot trials, we will scale-up the integration of these trucks across our cement operations in India.”

Honduras: Cementos Argos Honduras has commissioned a 1.6GWh/yr solar power plant at its Choloma grinding plant in Río Blanquito. Grupo Argos’ energy subsidiary Celsia built the plant, which consists of 2160 photovoltaic modules. The La República newspaper has reported that the installation cost US$1.2m. It will supply 25% of the Choloma grinding plant’s energy consumption, and reduce its total CO₂ emissions by 23%.

Cementos Argos Honduras CEO Luis Eduardo Tovar said "This partnership marks a significant milestone in our efforts to address climate change and revitalise our ecosystems, while generating significant impact in communities with new employment and investment opportunities.”

Mexico: Cemex said that it has successfully implemented labelling showing the environmental impacts of all of its main products across its ‘most important markets.’ Depending on prevailing practices in each market, products’ packaging either displays an Environmental Product Declaration (EPD) or Cemex’s own third-party validated C_ERO₂ designation.

General director Fernando González Olivieri said “We are committed to being the leading partner in sustainable construction for our clients. In this way, our clients have environmental impact information that they can use to develop sustainable construction.” He added “We continue to expand our portfolio of sustainable products, allowing our clients to effectively design and manage the carbon footprint of their construction projects.”

The 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.

UK: James Whitelaw will take on the role of managing director in Hanson UK’s newly-established recycling business line. He will be responsible for identifying opportunities to grow organically using the company’s existing capabilities and for integrating new acquisitions.

Whitelaw has held management roles in Hanson UK since 2001 and most recently served as aggregates managing director. Former concrete managing director Brian Charleton will replace him in this role, while Gordon Napier, previously concrete regional director, joins Hanson UK’s executive team as the new concrete managing director.

Netherlands: Finland-based Coolbrook has completed the first test phase of the large-scale pilot of its RotoDynamic Heater (RDH) at the Brightlands Chemelot Campus in Geleen, Netherlands. The engineering company says that this has validated the RDH’s technical pathway up to industrial heat generation at temperatures suitable for cement plants. By developing and launching the technology, Coolbrook says that it will rely on a ‘comprehensive partnership ecosystem,’ including market leaders in technology and industry. It says that the RDH has the potential to eliminate 2.4Bnt/yr of CO₂ emissions – 30% of global industrial CO₂ emissions and 7% of all global CO₂ emissions.

CEO Joonas Rauramo said “Sharing our partners’ and customers’ sense of urgency to achieve net zero, we take determined actions to execute our strategy and progress towards the commercial launch of our electric technology. We are proceeding with first commercial agreements, while continuing to build our organisation and supply chain for industrial scale operations.”

Switzerland: Holcim has invested in CO₂ mineralisation technology developer Neustark. Neustark aims to remove 1Mt of atmospheric CO₂ by 2030 and sequester it in recycled construction and demolition waste. The company’s technology achieved Gold Standard certification as a method of CO₂ removal in March 2022. Holcim says that its investment advances its group commitment to putting clean technologies to work towards achieving net zero.

Holcim’s Europe regional head Miljan Gutovic said "At Holcim, we are working to decarbonise building for a net zero future, and Neustark's technology helps us reach this goal. After the successful demonstration of Neustark's solution in Switzerland, we are ready to scale up this carbon removal technology globally."

UK: Hanson UK has launched a recycling business line to process construction and demolition waste. The business will supply recycled materials for use in Hanson UK’s operations.

CEO Simon Willis said “Promoting circularity by recycling, reusing and reducing the use of primary raw materials is crucial to reaching net zero. The development of a separate recycling business line will allow us to provide the most sustainable products to our customers through circularity and innovation, to enable building more with less. It is another significant step towards achieving our aim of being the industry leader in the supply of sustainable, circular products.”
