From the Fundación Arquia Blog, architect Miren León, a specialist in sustainable design and energy efficiency, brings us an article calling for the reuse of construction materials through "upcycling," a method that helps reduce waste and mitigate the life-cycle impact of buildings.

Although many may have forgotten it today, RE-using is second nature to us. We have all reused shoeboxes, cans, or jars for a purpose different from their original intent: from "creating" new toys or decorative objects to storing marbles or childhood treasures. Since we have all done this on a small scale, why is it so difficult to do it on an urban scale?
