Holcim completes acquisition of Cand-Landi Group
27 June 2024Switzerland: 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."
Switzerland: Neustark has raised US$69m in a growth equity round to scale up its carbon dioxide removal technology. The funding, led by Decarbonisation Partners—a collaboration between BlackRock and Temasek—will support Neustark's aim to permanently remove 1Mt of CO₂ by 2030. Climate tech growth investor Blume Equity also joined the round, alongside existing backers Holcim, Siemens Financial Services, Verve Ventures and ACE Ventures.
Neustark has developed a technology that captures biogenic CO₂ at its source and utilises it in building materials through an accelerated mineralisation process. This method is currently applied at 19 carbon capture and storage plants in Switzerland, Austria, Liechtenstein and Germany, with 40 more under construction across Europe.
Johannes Tiefenthaler, co-CEO and founder at Neustark, said “We turn the world’s largest waste stream, demolition concrete, into a carbon sink. In the past year, we have already deployed our unique solution at 19 sites. This growth investment will take us into the next exciting phase of our mission, helping us to further scale our impact across Europe, enter new markets in North America and Asia Pacific, and develop new solutions to store even more CO2 in mineral waste streams.”
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."
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.”
Netherlands: EMC Cement and HES International plan to build a 1.2Mt/yr plant in Amsterdam to produce an alternative cement that contains 70% volcanic ash. The cement will also include recycled concrete fines. Production will be carbon neutral and consume 90% less energy than traditional ordinary Portland cement production. The Amsterdam plant is scheduled for commissioning by early 2026.
EMC Cement CEO Atle Lygren said "Our EMC Technology, by replacing 70% of Portland cement clinker, enables significant climate action without the need for costly carbon capture and storage, aligning with the demands of the United Nations Framework Convention on Climate Change and the Intergovernmental Panel on Climate Change."
Germany: Heidelberg Materials has secured a patent for a new method for producing Portland composite cement (PCC) using calcined clay and recycled waste cement. GlobalData News has reported that the process involves grinding clay with quartz and feldspar and calcining the clay, before mixing it with the cement. The PCC’s cement content varies from 30% to 80%, while its calcined clay content varies from 10% to 70%.
Holcim announces over 15 upcoming acquisitions in 2024
18 January 2024Switzerland: Holcim says that it aims to conclude 15 - 20 new acquisitions in 2024, and potentially ‘many more.’ The value of individual deals ranges from US$5.78 – 115m, but might possibly exceed US$230m. Holcim says that it is focussing on growing its construction waste recycling business in Belgium, France, Germany and the UK, as well as its aggregates business in Eastern Europe.
Holcim’s ECOCycle construction-demolition material recycling technology named Circularity Lighthouse
17 January 2024Switzerland: 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.”
Neustark sees potential in German market
04 January 2024Germany: Switzerland-based CO2 mineralisation technology developer Neustark says that it sees major potential for recycling concrete from construction and demolition waste (CDW) to produce carbon-negative products using its process in Germany. Neustark inaugurated its first German plant, and 12th overall, at Marzahn in Berlin in late 2023. Capital Online News has reported that the start-up estimates that Germany generates 60Mt/yr of CDW concrete, but only recycles 600,000t/yr (1%). This contrasts with international CDW concrete recycling rates as high as 15% in Switzerland and the US.
The start-up, founded at the Federal Institute of Technology Zurich in 2019, currently absorbs 10kg/t of CO2 in its recycled materials, but aims to reach 60kg/t. Its investors include Holcim.
Heidelberg Materials Mineralik and UM Recycling start demolition and construction waste partnership
27 December 2023Germany: Heidelberg Materials Mineralik has started a partnership with UM Recycling to use demolition and construction waste in the production of cement and concrete in the greater Frankfurt Area. UM Recycling, a subsidiary of Antal Group, specialises in the disposal and recycling of construction waste and other materials.
George Antal, the owner of the Antal Group, said “After more than 15 years of active work in the dismantling industry, we are looking forward to working with our partner Heidelberg Materials to transform mineral waste into a product for use in concrete and cement, thereby making a valuable contribution to holistic building material recycling."
Heidelberg Materials operates several ready-mixed concrete plants around Frankfurt and runs a cement grinding plant at Mainz.
