I’ve always been charmed when recycled bottles are used as eco-friendly design details, but I was blown away by the school in the Philippines constructed earlier this year using bottles. How cool! According to Good Magazine, “The bottles are filled with adobe, made from local mud which sets like concrete, and layered within a steel frame. The resulting wall…is three times stronger than one built with traditional materials (wood, bamboo, and straw)—which is no small thing in a country regularly hit by typhoons.”
