When you hear about broken bottles being strewn all over the road, it hardly seems like a friendly place for driving. But if you’re in Montana, driving over broken glass is commonplace, as more and more roads are using recycled glass to add improved consistency and appearance to the pavement. This according to PERC Reports, which notes that cities like Livingston have recently purchased pulverizers that turn discarded glass into a cullet, which is the course material that resembles gravel. And rather than tear up the landscape to get pavement dirt, the Montana Department of Transportation can now use 900 tons of glass bottles to help re-pave roads like it did recently to a Jefferson County Highway. Such use for glass seems like a sharp idea, indeed.
