What can we do with the garbage we create? People are searching for answers. Some are unique. In 1995, architect Kate Warner built a house in Martha's Vineyard, Massachusetts. She used materials most people call trash. The builders mixed concrete with ash left over from furnaces that burn trash. Then they used the mixture to make the foundation of the house. To make the frame of the house, they used wood left over from old buildings, not fresh lumber. "We ask people to recycle, but then we don't know what to do with the stuff," Warner says. "By making use of waste materials, the manufacturers of these new building materials are creating exciting new markets and completing a loop." In this loop, materials are used over and over again. Garbage becomes a natural resource. Click on Internet Activities at the left for help in completing the Chapter Review Activity on page 125 of your textbook.
