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.
Holcim and others launch SMI Circularity Taskforce at COP28
04 December 2023UAE: Holcim has launched and become a founding member of the SMI Circularity Task Force in collaboration with the Sustainable Markets Initiative (SMI) and others. The SMI Circularity Taskforce aims to accelerate the development of the global circular economy, in complement to Holcim’s goal of recycling 10Mt of construction-demolition materials (CDM) by 2025, and 20Mt in Europe alone by 2030. Holcim and its partners launched the task force at the COP28 climate conference in the UAE on 4 December 2023.
Holcim chair and chief executive officer Jan Jenisch said "With our world’s rising population and urbanisation, we need to build better with less to raise living standards for all while preserving nature. Circularity is a gamechanger to make this happen at scale. At Holcim we are driving circular construction across all metropolitan areas where we operate to build cities from cities, recycling CDM into new building solutions. I am excited to be joining like-minded organisations to accelerate the shift to a more circular future together."
European Union eases up on sustainable packaging
23 November 2023Europe: The European Parliament voted in favour of multiple amendments to the European Commission’s Packaging and Packaging Waste Regulation (PPWR) on 22 November 2023. The amendments remove, modify or make non-binding the PPWR’s 2040 reuse targets. Meanwhile, 2030 targets were made adjustable to recycling rates. Total packaging volumes are still required to drop by 5% by 2030 and by 15% by 2040 in each member state.
Sustainability lobbying organisation Environmental Coalition on Standards (ECOS) described the introduction of recycling rates into a lower schema of waste targets as ‘comparing apples with pears.’ ECOS attributed the amendments to a ‘barrage’ of false claims, scaremongering and lobbying from industry players.
ECOS programme manager Mathias Falkenberg said “This decision will not sufficiently address rising plastic and packaging waste or the pollution crisis. The European Parliament has just weakened a perfectly feasible solution to tackle throwaway culture without offering an alternative. It is very frustrating that the European Commission’s progressive prevention and reuse agenda has not received full support from the Parliament today.”
ECOS founded the Alliance for Low-Carbon Cement & Concrete (ALCCC), an association of companies focused on alternative building materials production, in May 2023.
France: Holcim France has commissioned its new Saint-Laurent-de-Mûre alternative raw materials plant in Rhône Department. The unit produces cementitious paste from construction and demolition waste using Holcim’s ECOCycle upcycling process. It will source construction and demolition waste from the Lyon Metropolitan Area.
Holcim’s global head of circular construction Vincent Teissier said “Advancing such circular technologies is one of the main pillars of our sustainability strategy. This new advanced crushing unit in Saint-Laurent-de-Mûre is a major step toward using construction and demolition materials to their full value.”
James Whitelaw to head Hanson UK’s new recycling line
20 September 2023UK: 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.
Hanson UK launches construction and demolition waste recycling business
20 September 2023UK: 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.”
France: Heidelberg Materials has announced plans for its CIRCO₂BETON concrete recycling project. It intends to build an industrial-scale selective separation unit at its Achères quarry near Paris. Here it will recycle demolished concrete by crushing it and separating it into its components: sand, aggregates, and recycled concrete paste (RCP). The recycled sand and aggregates will be reincorporated into new concrete.
The RCP will be transported to the Ranville cement plant in the Normandy region. There, a reactor for enforced carbonation will be installed to carbonate the RCP by exposing it to CO₂-containing exhaust gases from the kiln. The carbonated RCP acts as a carbon sink and will replace clinker in new low-carbon cement types. The project has the potential to reduce the CO₂ emissions of the Ranville cement plant by 20%.
CIRCO₂BETON is supported by the ‘Investment for the Future’ Program coordinated by the Ecological Transition Agency (ADEME). In addition, the Île-de-France region supports the selective separation plant at Achères through its zero-waste and circular economy plan. Subject to the funding, construction of both industrial pilots is scheduled to start in 2024 with production of RCP starting in 2025. The carbonation reactor is planned to be operational by 2026.
Nicola Kimm, the chief sustainability officer at Heidelberg Materials, said ”We are investing in a pioneering large-scale project based on innovative process technologies. Selective separation and CO₂ mineralisation are important levers to reduce the carbon footprint of our products. By closing the materials loop, we prove that concrete has the potential to be the most sustainable building product over its entire life cycle from production to recycling.”
