Switzerland/US: LafargeHolcim and GE Renewable Energy have signed a memorandum of understanding to research new ways to recycle of used wind turbines. The partners are seeking to use the shredded blades to produce low-CO₂ building materials. LafargeHolcim said that undertaking builds on the work of its subsidiary Geocycle, which previously began using GE’s waste wind turbine blades to produce alternative fuel (AF) for cement production. The cement producer called recycling the ‘key next step’ in line with the Circular Economy Action Plan of the European Union’s European Green Deal.

Switzerland: LafargeHolcim has announced its participation in a project aimed at increasing the height of wind turbine towers by producing larger bases on-site using 3D concrete printing technology. LafargeHolcim will supply concrete for use with Denmark-based COBOD’s 3D printing technology, while US-based GE Renewable Energy backs the project. The method enables bases to exceed the 4.5m maximum diameter necessitated by road transportation. This increases the maximum height of turbine towers by 100% to 200m from 100m, which in turn raises power generation by 33% to 20.2GWh/yr from 15.1GWh/yr.

LafargeHolcim research and development head Edelio Bermejo said, “Concrete 3D printing is a very promising technology for us, as its incredible design flexibility expands the realm of construction possibilities. Being both a user and promoter of clean energy, we are delighted to be putting our material and design expertise to work in this ground-breaking project, enabling cost efficient construction of tall wind turbine towers and accelerating access to renewable energy”
