The Billings, Montana-based Northern Plains Resource Council is paving its headquarters parking lot with pulverized glass, reports the Billings Gazette. (Scroll past the Old Chicago news to the permeable paving note.) Geotextiles and recycled plastic rings provide the subgrade support and soil separation. Recycled glass surfacing has gained some momentum in northern states. For more on pulverized glass, check out this January 2005 column from Cynthia Andela in American Recycler at this link http://www.americanrecycler.com/0105glass.shtml
