TRÆ in Aarhus, Denmark, is built in part from reused construction waste. Designed by Lendager Architects for Kilden & Hindby and PFA Ejendomme, in collaboration with MOE Consulting Engineers and Kaj Ove Madsen, Aarhus Municipality and Realdania, it is due to be completed 2024. Reuse and recycling innovations in the facade include the use of decommissioned composite wind turbine blades for solar shielding, aluminium roof plates for the facade, wooden cassettes, wood insulation, low-carbon concrete and insulation from waste textiles. The reused aluminium facade comes from two different renovation projects, where they had been discarded, plus water-damaged panels from a supplier. Standing 78 m high, the structure is steel, concrete and timber. All materials have been thoroughly tested so that they continue to meet the requirements and regulations.
