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.”

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.

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.”

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.”

Belgium: The European cement association, Cembureau, has asked the Europen Union (EU) to provide a regulatory framework to support the work of the European cement industry in co-processing waste composite materials as alternative raw materials. The materials in question consist of glass, carbon or other fibres and polymer matrices. The association called on the EU to recognise co-processing as ‘recycling’ under the EU Waste Framework Directive, to establish waste composite materials collection schemes and phase out landfilling, and to introduce dedicated waste codes for the materials. Cembureau said that the last of these proposals would help to increase visibility and attract investments.

Cembureau set out its proposals in a joint statement with resins associations Cefic UP/VE and Cefic Epoxy Europe, boating association EBI, composite materials association EuCIA, glass fibre association Glass Fibre Europe and wind energy association WindEurope.

Finland: Tana Oy has appointed Kalle Saarimaa as its chief executive officer with effect from 1 June 2023.

Saarimaa is currently working as the Senior Vice President for Circular Solutions at Fortum Oyj. However, he has been a member of the board of Tana Oy since 2021. Prior to working for Fortum Oyj he held posts with Ekokem and Walki Oy. He is also active in Finnish and European waste management organisations and as a board member of circular economy companies.

Tana sells products to the recycling and landfill sectors such as shredders, compactors, screeners, sifters and more.

India: The municipal corporation of Kolkata, West Bengal, has enacted regulations requiring landowners to send construction waste from projects on their property to construction and demolition waste recycling facilities. The Telegraph newspaper has reported that the new regulations apply to all construction, demolition and repairs work on plots of land larger than 0.24 hectares. The city authorities have built a 183,000t/yr recycling plant in New Town, Greater Kolkata, to support the increased volumes.

India: More than 75 representatives from academic institutions and businesses from across the world are attending the Innovandi Global Cement and Concrete Research Network (GCCRN) Spring Week taking place in New Delhi. The GCCRN has brought together 450 researchers and scientists from more than 40 universities and institutions, including the EPFL in Switzerland, South East University in China, University of Toronto in Canada, the Indian Institute of Technology Delhi, the University of Cape Town, Imperial College London in the UK, as well as 35 cement and concrete manufacturers and their suppliers. The focus of the conference is to work towards reaching net-zero CO₂ concrete production, including sourcing and improving alternatives to clinker, work on calcined clays, concrete recycling – plus its carbonation and durability - as well as kiln electrification and carbon capture, usage and storage (CCUS).

Claude Loréa, the Innovation and ESG Director at the Global Cement and Concrete Association (GCCA), said “Global Innovation collaboration and research will help unlock our industry’s decarbonisation mission. Spring Week is the key date in the GCCA’s Innovandi calendar. It provides an opportunity for our partners to meet face-to-face, exchange ideas, run workshops, and measure progress on key research projects in line with our industry’s 2050 Net Zero Roadmap. Our industry and our key partners are stepping up to the challenge and it’s fantastic to see the progress on some of the 75 PhD candidates supported by the GCCRN.”

The event is also updating attendees about progress made by projects involved with the Innovandi Open Challenge. This initiative matches start-ups with GCCA member companies from around the world, to help scale up research and technical innovation. Two of the six start-ups selected in 2022 at the first ever Innovandi Open Challenge, which focused mainly on carbon capture and utilisation, have already gone to pilot stage. Applications for the second challenge, which focuses on low carbon concrete, close on 15 May 2023.

The GCCRN was set up by the GCCA, a lobbying group representing more than 80% of the world’s cement and concrete manufacturers outside of China. All GCCA member companies are committed to decarbonising the industry by the mid-21st Century, in line with the GCCA’s Concrete Future 2050 Net Zero Roadmap.
