Major Water Project Utilizes Recycled Glass for Construction
ANCHORAGE – Solid Waste Services (SWS), Anchorage Water & Wastewater Utility (AWWU), and Central Recycling Services (CRS) have partnered to use locally produced recycled glass aggregate in AWWU’s Northern Lights Water Main Rehabilitation Project. AWWU will use 3,000 tons of the locally recycled glass in the project.
Each year in Anchorage SWS, CRS, and Alaskans for Litter Prevention and Recycling divert 1,200 tons of glass from the Anchorage Regional Landfill. CRS crushes the diverted glass into recycled aggregate at their facility in Ship Creek. The recycled glass aggregate is a Class-E bedding material, and is being used to encourage its use instead of gravel in similar construction projects.
“Glass never truly breaks down once it enters the landfill and we never reclaim that landfill airspace,” said Mark Spafford, SWS General Manager. “Diverting glass extends the life of the Anchorage Regional Landfill which keeps rates low for our customers and preserves this resource for future generations.”
“Locally recycled materials have the greatest potential to divert the waste stream into usable products. The Municipality’s leadership in developing material specifications and supporting the use of locally recycled construction materials closes the loop with a sustainable end market,” said Donna Mears, Environmental Engineer with Central Recycling Services. CRS has produced recycled glass aggregate since late 2012.
The use of recycled glass aggregate adds no cost to AWWU’s project budget. Projects such as the Northern Lights Water Main Rehabilitation develop long-term, sustainable end markets for recycled glass aggregate and expand Anchorage diversion and recycling programs.
