Watch NRRA’s Webinar:  Processed Glass Aggregate: A Certified Waste Derived Product

Glass collected through community recycling programs consists primarily of clear, green, and brown food or beverage containers. Decades ago it was economical to sort this glass by color, but the market price for recycled glass as cullet continues to decrease and the trend is not shifting. For this reason, many state environmental protection and/or transportation departments encourage safe and credible alternative uses of recycled glass as a replacement for other natural aggregate materials (gravel, crushed gravel, or crushed stone). NRRA’s PGA program outlines the requirements for the acceptable use of uncontaminated, mixed color, processed glass aggregate (PGA) as backfill material, drainage, subbase layers, roadway applications, embankments and foundations.  (.75 hour/NH DES credit available)
