The mission of the Solid Waste & Recycling
Program is to divert valuable reusable materials from the waste stream and
provide them to recycling markets, eliminating much of the trash that ends
up in landfills and incinerators.

Glass as a Building Material
Glass aggregate
is a valuable building resource. It is a dense and relatively inert
material that can be processed into many valuable applications. It has
been scientifically proven to be useful as:
»
aggregate substitute for gravel and sand in road construction.
»backfill
in ditches and around pipes
»abrasive flooring
»
counter tops and tiles
»
cement
»
turf and soil amendment
»
decorative landscaping
»
water filtration
» traction
sand
» drainage
medium
» landfill
cover
» sandblasting
»
utility bedding

Clear Solutions for Glass Recycling
MontPIRG is working to make sure glass recycling has a permanent place
in Montana. Student interns working on the glass recycling campaign
are focusing on building support from communities for solutions they hope
to take to the legislature next January.
Unlike other recyclables, glass is too costly to ship to nearby recycling
centers in Denver or Seattle. “This means that communities are forced
to be creative in how they recycle glass,” said MontPIRG intern Martin Fahrney.
“A few communities have been very innovative, but most communities don’t have
the time or the funds to invest in new recycling programs.”
So MontPIRG is working to make funds available through the Montana Department
of Transportation for the purchase of portable glass crushers.
Many communities across the country successfully use glass crushers to create
building materials.
Recycled glass is a virtually free building material that can be used
in everything from roads to backfill to insulation, if processed correctly.
“What we have here is a building resource that we are sending to the landfill
by the truckload everyday,” said Erin Heidrich, MontPIRG intern. “If
Montana were to purchase a transportable machine that could move from community
to community and process waste glass, cities wouldn’t have to struggle to
maintain glass recycling programs.”
Communities in Montana have worked to establish glass-recycling programs.
These programs have struggled due to a lack of statewide support. Now there
is a way to turn used glass into a valuable resource throughout Montana.
MontPIRG is helping to draft a bill to be introduced
in the 2003 legislative session that would provide glass pulverizers for
your use and benefit. Cities and towns across Montana can use these pulverizers
to process glass into sand and smooth gravel for use in various municipal
projects. In peer states such as Taos, New Mexico and King County, Washington
pulverized glass is already used in road construction, community water supply
filtration, and even in playgrounds.
A state wide glass recycling program will benefit communities by decreasing
costs for waste and raw material transportation, and by extending the life
of your landfill. The glass aggregate from these pulverizers is also an
environmentally friendly alternative in that it decreases air and water
pollution by replacing resources that require excavation.
