Processed Glass Aggregate

Every year, recyclers collect and process thousands of tons of container glass for use in the manufacture of new glass containers. During the process some of the glass becomes broken, colors are mixed or otherwise contaminated and cannot be used in container manufacturing.

There is another option to capture a higher amount of material from recycling programs where recyclers are developing alternative markets for glass, including applications for recycled glass as a construction aggregate.

Because of the high demand in the glass recycling markets for clean, color separated glass, the economics of sorting and transportation can be substantial thus realizing the cost savings of glass aggregate applications. This provides the municipal recycling programs additional opportunities to reduce a portion of the waste stream that typically ends up in the landfill as regular solid waste. Municipalities may now add other types of glass to the recycling programs such as: stemware, mugs, plates, cups, ceramics, PYREX, glasses, and vases.

The use of recycled glass as a high performance substitute for sand and aggregates have been studied and proven to work ideally in applications of construction.

For example, with excellent drainage and permeability, glass aggregate can be used for:

Aggregate for gravel road base
Backfill for foundations
Backfill for walls
Drainage pipe bedding
Rigid Pipe bedding
Drainage blanket
Sloping material
Foundation material
The State of New Hampshire was the first in the Nation to adopt specifications allowing crushed glass as an aggregate and the NHDOT specifications are available here. (link) The State of NH is also experimenting with glass in other areas of construction.

Turnkey Recycling and Environmental Enterprises in Rochester NH now offers processed glass aggregate as an alternative material to: construction companies, Road Agents and Public Works Departments for use as an aggregate to road base materials or culvert and pipe bedding.

Waste Management of New Hampshire, Inc.- Rochester is the first Solid Waste Management Company in the State of New Hampshire to provide this collection service extending our relationships to the communities we service.
