Aluminum and the Sustainable Home: What You Should Know
After oxygen and silicon, aluminum is the most abundant element present in the earth’s crust, making up well over eight percents of the crust by weight. While still a non-renewable resource, we will not be running out of aluminum any time soon. Starting about a century ago, architects realized that the strong but lightweight aluminum properties made it an excellent choice for large building projects. In 1931, large parts of the Empire State Building in New York were built with aluminum, including the famous spire that reached high into the New York skyline.
