1. Asphalt ShinglesShingles have to be tough to survive the scorching and bone-chilling temperatures a roof suffers. Once their roofing lifespan ends, shingles can be recycled into pavement projects such as patching potholes. Moreover, because asphalt shingles contain crude oil, they can also be repurposed as fuel for cement kilns and other operations.

2. Reclaimed WoodProvenance, beauty, and strength—these are the characteristics that make reclaimed wood products so appealing to today’s designers and consumers. Many older buildings contain weathered wood products that can be milled and processed into stunning new products, such as paneling, flooring, and countertops. Reclaimed timber may also be used for structural lumber in new building projects.

3. SteelSteel is the one of the most frequently recycled materials on the planet, for the simple reason that it doesn’t lose structural strength after being recycled. For more than 150 years, recycled steel has been used in new buildings, bridges, cars, and more. Recycled steel is less expensive to produce than virgin steel. Plus, recycling steel causes far fewer carbon emissions than extracting new steel. In 2008, scrap metal recycling was an $86 billion industry that supported 85,000 good-paying American jobs. Steel salvaging and similar recycling efforts help to offset the country’s trade deficit while replacing former manufacturing jobs.

4. DrywallSandwich gypsum between two sheets of paper and you have drywall. Its high recycling value is due to drywall’s varied recycling potentials: Gypsum scraps can be used to patch walls, to form concrete, or to create new drywall. The gypsum in drywall is beloved by gardeners, who use it to nourish plants. Finally, the paper in drywall can be recycled as well. Salvaging drywall is an Earth-friendly operation, not only because it reduces landfill volumes, but also because drywall in landfills can leak sulfate into nearby watersheds.

5. Glass and WindowsLike steel, glass can be repeatedly recycled with no loss of quality. Environmentally conscious consumers and businesses are drawn to glass because it’s inherently green—for every ton of glass that’s recycled rather than extracted, a ton of natural resources are saved. Windows salvaged from demolition sites can be recycled for any number of applications, from sandblasting to paving parking lots.
