The slab has been built at the Demopark of ACCIONA\u2019s Technology Center, located at the company\u2019s Central Workshops in Algete (Madrid).<\/p>\n<p>The new material is based on Holcim\u2019s own ECOPact concrete featuring ECOCycle\u00ae technology, which includes 11% recycled material in the form of recycled aggregates and, as a novel addition, shredded wind turbine blades that have reached the end of their useful life. The prototype also features ECOPlanet CEM V\/A (Q-S) 42.5N cement, which has a small carbon footprint thanks to its low clinker content, resulting in a 49% reduction in CO\u2082 emissions compared with the reference cement (sectoral EPD CEM I).<\/p>\n<p>This latest example of the circular economy in action marks a key milestone within the wider European innovation project known as BLADES2BUILD; a consortium involving both companies that aims to develop new recovery pathways for composite materials sourced from wind turbines.<\/p>\n<p>This initiative is closely aligned with ACCIONA\u2019s efforts to incorporate innovative, low environmental impact materials into its projects, championing the reuse of resources and emissions reduction to offer its clients more sustainable, efficient and innovative construction solutions in line with its decarbonization strategy.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-39194\" src=\"https:\/\/cdn-imnov.comun-pro.eu-west-1-aws.cloud-acc.net\/wp-content\/uploads\/2025\/10\/30133811\/EU_holcim_acciona.jpg\" alt=\"\" width=\"956\" height=\"131\" srcset=\"https:\/\/cdn-imnov.comun-pro.eu-west-1-aws.cloud-acc.net\/wp-content\/uploads\/2025\/10\/30133811\/EU_holcim_acciona.jpg 1014w, https:\/\/cdn-imnov.comun-pro.eu-west-1-aws.cloud-acc.net\/wp-content\/uploads\/2025\/10\/30133811\/EU_holcim_acciona-768x105.jpg 768w, https:\/\/cdn-imnov.comun-pro.eu-west-1-aws.cloud-acc.net\/wp-content\/uploads\/2025\/10\/30133811\/EU_holcim_acciona-60x8.jpg 60w, https:\/\/cdn-imnov.comun-pro.eu-west-1-aws.cloud-acc.net\/wp-content\/uploads\/2025\/10\/30133811\/EU_holcim_acciona-430x59.jpg 430w, https:\/\/cdn-imnov.comun-pro.eu-west-1-aws.cloud-acc.net\/wp-content\/uploads\/2025\/10\/30133811\/EU_holcim_acciona-725x99.jpg 725w\" sizes=\"auto, (max-width: 956px) 100vw, 956px\" \/><\/p>\n<p><em>Funded by the European Union.
