Ellensburg Glass Recycling Cooperative
Crushing it!
ERGC is looking for changemakers!
Have a business that can use glass materials?
ERGC needs entrepreneurs that can use our products in their craft. We are in the process of sieving our New Sand into 5 grades.
These different grades of sand and our grades of Shrub Steppe Sea Glass have many commercial uses: filtration, art, sandblasting, abrasive surfacing, terrazzo, bedding, fill, sand replacement, and filler (to name a few). With further innovation building materials and mineral extraction is possible.
Join us in expanding glass recycling in Kittitas County.

ASTM Standards
ASTM is an organization that publishes standards for many different materials. On their website you will find hyperlinked tests that have been the ASTM certified. Once a procedure makes it to this list it is safe to assume an accepted result. This allows users confidence in knowing that it is a safe process to be duplicated.
There is a lot of information for non-container glass on this link, but there are many glass categories as well. Click the link below to find out more.
Federal Standards
Here are some links to federal standards and guidelines for using recycled glass. The Federal Highway Administration Research and Technology Coordinating, Developing, and Delivering Highway Transportation Innovations is a document that is much shorter than it sounds. About 2 pages long, it discusses applicability of glass in roadways.
The other link takes you to the Environmental Protection Agency's Comprehensive Procurement Guidelines (CPG) for Miscellaneous Products webpage. Here it has a variety of materials, Blasting Grit being one that can use 100% recycled glass in line with appropriate sieve size and cleanliness standards.
State Standards
There is all sorts of information in the Washington State Department of Transportation: Standard Specifications for Road, Bridge, and Municipal Construction 2021, but you may have to dig to find information on using recycled glass. Division 9-Materials outlines material requirements. 9-03.21 explains specifications on using Recycled Materials, and glass is addressed in "9-03.21(1)D Recycled Glass" (glass cullet).
There is also a chart "9-03.21(1)F Table on Maximum Allowable percent (By Weight) of Recycled Materials" explaining public projects and to what percentage these materials must be mixed with raw materials.
