    Holcim UK circular construction push: recycling strategy and targets for engineers

    Holcim UK circular construction push: recycling strategy and targets for engineers

    First reported on The Construction Index

    30 Second Briefing

    Holcim UK has promoted former northern aggregates regional director Shaun Elliott to managing director for recycling, tasking him with maximising recycling performance and integrating it across the business. The company now operates eight recycling centres after acquiring PJ Thory, Gemmix, Pro Minimix and Thames Materials, expanding capacity to process construction and demolition materials into certified secondary aggregates and cementitious products. Globally, Holcim is targeting annual recycling of 20 million tonnes of CDM by 2030, lifting cement recycled content to 30% and using 70 million tonnes of waste and by-products as alternative fuels and raw materials.

    Technical Brief

    • Recycling centres are configured to convert CDM into high-quality, certified secondary aggregates and cementitious products.
    • Certification implies compliance with existing aggregate and cement standards, enabling structural and pavement-grade reuse rather than downcycling.
    • Integration of recycling into aggregates, ready-mix and logistics units should streamline CDM feedstock sourcing and outbound product distribution.
    • Stated ambition that “every tonne” delivers “maximum value” points to tighter yield control and reduced landfill residues.
    • Emphasis on “technology, assets and expertise” indicates existing fixed-plant crushing, screening and possibly advanced separation for contaminants.

    Our Take

    Holcim UK’s M&A activity around PJ Thory, Gemmix and Pro Minimix, combined with a 20 Mt/y CDM recycling target, signals a push to internalise both primary aggregates and secondary/recycled feedstock streams rather than relying on third‑party recyclers in the UK cement and concrete supply chain.

    The 30% recycled-content target for cement by 2030 aligns with Holcim UK’s later public advocacy for mandatory EPDs, suggesting they are positioning to monetise lower embodied-carbon mixes once disclosure becomes a regulatory requirement on UK projects.

    Within our Materials coverage, cement is one of the few commodities where corporate circularity targets (like Holcim’s 70 Mt waste and by-product recycling goal) are being paired with acquisitions of local recycling and secondary aggregate assets, which may pressure smaller UK independents that lack similar vertical integration options.

    Polypipe Aylesford automation: process, quality and staffing shifts for engineers

    Plastic pipe manufacturer Polypipe Building Services has invested £1.5m in automation, £3m in moulding machinery and £2.5m in extrusion technology at its 24-hour, five-day Aylesford plant, moving key lines to fully automated operation. Six-axis and Cartesian robots now handle production and packaging, while an IV4 AI vision camera counts parts and flags dimensional variation, ovality and moulding defects before dispatch. Operator loading has shifted from one operator per machine to typically one per four machines, with staff redeployed and further automation planned in the fabrication department.

    Breedon completes Irish acquisition: supply chain and materials lens for engineers

    Breedon has completed its acquisition of Booth Precast Products in Abbeyleix, County Laois, adding a long-established sand and gravel quarry and processing plant that has supplied the Irish construction market for over 25 years. The deal, agreed in December 2025 and cleared by the Republic of Ireland’s Competition Authority, secures additional mineral reserves to serve the growing Dublin market. Integration of Booth’s concrete operations gives Breedon Ireland a more vertically integrated aggregates-to-concrete supply chain for regional infrastructure and building projects.

    UK Concrete Show 2026 seminar line-up: decarbonisation and QA/QC focus for engineers

    The UK Concrete Show 2026 at Birmingham’s NEC on 25–26 March will run a seminar programme centred on decarbonisation, materials innovation, digital monitoring, performance verification, and skills development for concrete producers and specifiers. Sessions will address low‑carbon binders and mix designs, sensor‑based monitoring of pours and in‑service structures, and verification of performance against evolving standards. The focus on skills suggests practical content for contractors, precast manufacturers, and designers needing to integrate new materials and digital QA/QC into existing workflows.
