recycled content roofing
The roofing industry is developing products that reuse waste from other industries. For instance, waste from manufacturers of car hoses, shoes, tires, and other rubber products is now being directed to the manufacturing plant of EcoStar, Inc., which makes a 100% recycled lightweight rubber "slate" tile.
Another recycled product, the eco-shake®, looks like wood and contains reinforced vinyl and cellulose fiber.
