Spain: Cementos Molins has processed 75,000t of waste into alternative raw materials for use in its cement production since opening its Barcelona alternative raw materials plant in September 2022. The plant has a production capacity of 200,000t/yr. It produces the materials from construction and demolition waste and various industrial by-products.

Cementos Molins’ director of corporate development and sustainability, Carlos Martínez, said “Our commitment to the environment is intrinsically linked to our business model, which is based on the development of sustainable and innovative materials.” He continued “We provide a second life to industrial and construction waste that would otherwise end up in landfills, generating high-quality sustainable products from them. The plant has enabled all our cements to incorporate alternative raw materials in their production process. Furthermore, we are working to reduce the carbon footprint of all our concretes, ensuring that, in the short term, all of them include recycled aggregates in their manufacture."

UK: Cemex UK says that it has collected 130,000t of by-pass dust (BPD) from its Rugby cement plant in Warwickshire since 2015. The producer supplies the BPD to the agriculture sector, where it can replace traditional fertilisers and lime due to its high lime and potassium content. Additionally, Cemex UK has sponsored research into this and other circular economic uses of BPD, including an on-going study which claimed the Carbon Journey Award at the Eco Innovation North West Awards 2023.

Cemex’s Europe regional head of sustainability Paul Fletcher said “We are very proud of our partnership with Silverwoods and the considerable positive impact their innovation and expertise has had on our ability to reuse BPD for other applications. We believe it leads the way in our industry and presents real potential to be adapted elsewhere across our operations. Not only does it benefit the environment by reducing the amount of materials that need to be disposed of, but it generates a product that has a value for farmers and helps cut the use of traditional materials.” He added “This partnership demonstrates that to deliver true circularity, more industrial by-products, including those from different sectors of the economy, need to be used as secondary resources, rather than primarily be seen as waste. If this is to be achieved, a new perspective is needed to boost circular economy practices, with regulations and permitting supporting this proactively.”

US: Heidelberg Materials is rumoured to have hired advisors for a possible attempt to acquire Summit Materials. Bloomberg has reported that the company made two approaches to Summit Materials ‘in recent weeks.’ Meanwhile, the Colorado-based producer revealed in a statement that it has rejected two takeover bids from an unnamed party, the more recent on 18 October 2023.

Summit Materials previously agreed to merge with Cementos Argos subsidiary Argos USA in early September 2023.

Romania: Holcim Romania has successfully upgraded pyroprocessing and cement grinding equipment at its Câmpulung cement plant in Argeș County. Germany-based KHD Humboldt Wedag supplied equipment for the upgrade. For the plant’s pyroprocessing line, this included a downcomer duct, water injection system and induced draught fan, as well as an upgrade to the clinker cooler. Meanwhile, the grinding line has received a new SKS Z 2500 dynamic separator, cyclones, process ducts and separator fan. The supplier says that the upgrade has increased the Câmpulung plant’s clinker capacity and the efficiency of its operations. The work took 14 months to complete from the signing of the contract in mid-2023.

Croatia: Nexe Group has completed a US$3.3m upgrade to its Našice cement plant. SeeNews has reported that the project consisted of efficiency-increasing upgrades to the plant and other buildings at the site, and the construction of a solar power plant. The producer says that this will reduce the 600,000t/yr-capacity cement plant’s total energy consumption by 1.56GWh/yr.

The Našice cement plant is the site of an on-going expansion and carbon capture system installation project.

Mexico: The government says that if US-based Vulcan Materials continues to reject offers for land in Quintana Roo on which its Calica-Sac-Tun quarry is situated, then it will designate the land Protected Natural Area status. Reuters has reported that the government has previously offered US$328 – 383m for the property. Vulcan Materials has mounted on-going legal challenges worth US$1.9bn against the Mexican government over the previous closure of its operations.

Spain: 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.

Germany: Heidelberg Materials preliminary reported a 4% year-on-year decline in its sales during the third quarter of 2023, to Euro 5.6bn. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 17% to Euro1.39bn from Euro1.28bn. The group succeeded in raising its profit in the quarter, by 24% year-on-year to Euro1.08bn.

India: Udaipur Cement Works commissions second kiln line at its Udaipur cement plant in Rajasthan. Reuters has reported that the new line doubles the plant’s clinker capacity to 3Mt/yr.

India: Sagar Cements reported sales worth US$136m in the first half of the 2024 financial year. This corresponds to a year-on-year rise of 9.1% from US$124m in the first half of the previous financial year. The producer recorded a loss for the period of US$6.31m, down by 3.9% from US$6.57m. This was in spite of a 7.8% rise in its total costs, to US$148m.
