Switzerland: Holcim has acquired recycling, ready-mix concrete and aggregates company Cand-Landi Group. The company employs 250 people across its operations in Western Switzerland. Holcim plans for Cand-Landi Group to supply alternative raw materials and fuels for use at its Eclépens plant. It says that the acquisition will increase its recycling capacity of construction and demolition materials by 100,000t/yr.

Holcim CEO Miljan Gutovic said "The acquisition of the Cand-Landi Group will advance decarbonisation and circularity in Switzerland, a lighthouse market for innovation at Holcim. I look forward to welcoming all 250 employees of the Cand-Landi Group and investing in our next chapter of growth together."

Philippines: OceanaGold Philippines (OGPI) is collaborating with Holcim Philippines to assess the feasibility of using mine tailings in cement production. Holcim will begin by acquiring tailing samples from OGPI for initial testing, aligning with its ‘circular economy’ program that integrates waste materials into cement. Both companies are committed to advancing the study, pending formal partnership arrangements and necessary permits.

OGPI President Joan Adaci-Cattiling said “We’re just waiting for the permit. Right now, we’ve found a way to put plan tailings to good use.”

UK: Holcim has completed the acquisition of Land Recovery. This acquisition broadens Holcim's access to construction demolition materials, with Land Recovery having recycled over 300,000t in 2023. The deal follows the previous purchase of Sivyer Logistics.

CEO of Holcim, Miljan Gutovic, said "Land Recovery strengthens Holcim’s leading position in circular construction and advances our group target of recycling 10Mt of construction demolition materials in 2024. I look forward to welcoming all 85 employees of Land Recovery and investing in our next era of growth together."

US: Holcim’s Hagerstown plant in Maryland has increased its alternative fuels substitution rate to 45%, equivalent to 58,000t/yr of engineered fuel. This US$11m initiative utilises end-of-life materials like non-recyclable paper, plastics and fibres, sourced from commercial and industrial materials like packaging. Geocycle, a subsidiary of Holcim US, will process these materials at its new Cumberland facility, which has a capacity of up to 75,000t/yr.

Senior vice president of Manufacturing North for Holcim US, Michael Nixon, said "Expanding our alternative thermal energy use to 45% provides multiple environmental and economic benefits, from lowering the net carbon intensity of our cement to reducing our consumption of traditional fuels. Importantly, it enables us to play a role in the circular economy, offering a highly safe and ecological solution for unused materials."

US: St Marys Cement won three national awards at the Slag Cement in Sustainable Concrete Awards 2023. The producer won the awards for supplying its slag cement for the construction of Wixom Assembly Park in Wixom, Michigan; of 333 North Water in Milwaukee, Wisconsin, and of Excellerate Manufacturing in Appleton, Wisconsin.

UK: Heidelberg Materials UK has opened a new circular materials hub at its Appleford depot in Oxfordshire. The site will recycle construction waste for use in low-CO₂ building materials. The move advances the company’s strategy to conserve natural materials and support the circular economy.

Recycling managing director James Whitelaw said “Recycling, reusing and reducing the use of primary raw materials is crucial to reaching net zero. Our network of recycling hubs will allow us to provide the most sustainable products to our customers through circularity and innovation to enable building more with less.”

Indonesia: Siam Cement Group (SCG) subsidiary PT Semen Jawa used 24,000t of alternative raw materials in its cement production during the first quarter of 2024. These circular materials included bottom ash, fly ash and slag. This corresponds to 3% of its total raw material usage. Meanwhile, the producer co-processed 15,000t of alternative fuel (AF) during the quarter, representing a 20% AF substitution rate.

SCG Indonesia director Warit Jintanawan said that the developments "Not only enhance production efficiency, but also significantly reduces our carbon footprint. This is a testament to SCG's commitment to supporting Indonesia's climate goals, aiming to reduce greenhouse gas emissions by 32%, aligned with Enhanced National Determined Contributions."

India: Adani Group has announced plans to build a new cement plant, possibly at Godda, in Jharkhand’s Santhal Pargana Division. The Times of India newspaper has reported that producer recently established a 1.6GW power plant in Godda.

The group said “In keeping with our group’s expansion plans, we are conducting a feasibility study to set up a cement factory, most probably in Godda. A proposal will be sent to government soon. The proposed plant will further boost the economy of Godda and Santhal Pargana. The proposed plant will utilise fly ash from our existing power plant here as raw material. At present, the fly ash is being sent to the ACC cement plants in Jhikpani and Sindri.”

Switzerland: Carbon capture and storage (CCS) equipment developer and supplier Neustark says it plans to more than double the number of its CO₂ storage sites in Austria, France, Germany, Switzerland and the UK to 34 from 14. Neustark’s process turns mineralised captured CO₂ and existing mineral waste streams into useful limestone. Building materials producers lease Neustark’s storage sites to produce reduced-CO₂ alternatives such as recycled concrete. The sites currently have a total storage capacity of 5000t. Existing customers include Holcim.

Neustark CEO Johannes Tiefenthaler said “Neustark is scaling up rapidly, and we’re well on track to achieve our aim of permanently removing 1Mt of CO₂ by 2030. Our global goal is a series of reliable, region-specific CCS facilities that can be replicated anywhere, offering immediate sustainability benefits to local supply chains.”

Switzerland: McKinsey & Company and the World Economic Forum have recognised Holcim’s ECOCycle recycling technology for construction-demolition material (CDM) as a "Circularity Lighthouse in the Built Environment." ECOCycle technology can process 100% of CDM input into new building materials with 75% lower CO₂ emissions than traditional alternatives.

Chief sustainability officer Nollaig Forrest said “Circularity is a game changer to decarbonise buildings at scale. At Holcim we are operating over 100 ECOCycle recycling centres globally to drive circular construction. With our advanced recycling of CDM, we can already reduce the CO₂ footprint of cement by up to 40%. This is just the beginning; as we innovate and partner across the value chain to evolve building norms, we aim to accelerate the shift to circular construction in all metropolitan areas where we operate.”
