About This Quiz

The drive is on to build homes using fewer so-called virgin materials, and builders earn points for green building when they select materials that have been used before. While it's difficult, if not impossible, to build to code using only recycled materials, many recycled items are finding their way into every stage of construction. Take this quiz to see how certain items become building materials: by being renewed, reused or recycled?
