The Complete Lifecycle of Aluminum in Construction

The construction industry stands at a critical crossroads, where the traditional linear "take-make-waste" model must evolve into a sustainable circular economy. Aluminum, with its remarkable recyclability and durability, serves as the perfect example of how construction materials can complete a full lifecycle while maintaining value and performance. This comprehensive exploration delves into the complete journey of aluminum from extraction to rebirth in construction applications.
