  • Tire Shredding: The Best Alternative

    From cars and trucks to planes, tractors, and forklifts, tires are used for a wide variety of vehicles. And those tires don’t last forever. Regardless of how many miles a tire travels, it should not be used longer than ten years past its manufacture date, as the rubber will grow brittle and can crack. This isn’t usually a problem, though, since most tires are replaced within three or ...

  • Landfills: considering the alternative

    The economic side of landfill management isn’t easy. Essentially there is a “product” being sold— airspace. Revenue is generated through tipping fees charged per ton. The more garbage taken in, the more income earned. From that perspective, selling space is good. However, as more garbage is taken in, less space remains and the landfill’s lifespan decreases. ...
