“Glass Recycling Options, Processing and Markets: Santa Fe and Las Cruces Case Studies”

Danita Boettner, P.E. Santa Fe Solid Waste Management Agency & Keysha Burton South Central Solid Waste Authority

Santa Fe Solid Waste Management Agency

• City of Santa Fe purchased glass crusher (2003), Agency took over

(2007)

• Majority of glass received from City of Santa Fe (curbside collection)

and County Collection Centers, and BuRRT Recycling Collection Center, and others.

• Crushed glass markets/beneficial uses:
• Growstone, Inc., ABQ
• Landscaping (Commercial/Residential)
• Landfill protective/drainage layer (Caja del Rio Landfill Cell 5B Construction)
• Pipe trench bedding material (Caja del Rio Landfill Gas Collection System)

Solid Waste Assessment & Management Study – Louis Berger

• Continue to research markets for recycling glass
• Evaluate replacement of the glass crusher
• Consider outsourcing the material received

Pilot Study – Outsourcing (2015)

• Determined what processors may be in the region
• Strategic Material (Phoenix, AZ)
• Purchased Gaylord boxes with lids; pallets.
• Bid out transportation of 40,000 – 50,000 lbs (20 - 25 tons)
• April and December 2015
• $1,250/trip (backhaul)
• Loaded Gaylord boxes with small loader; moved with forklift.
• 4 hours, using two employees.
• Realized $30/ton rebate on material processed

Glass Processing Alternatives Evaluation

• Baseline
• Maintain Current Equipment and Material Processed by Agency
• Scenario 1
• New Glass Crusher Purchased and Material Processed by Agency
• Scenario 2
• All Glass Received is Outsourced to Strategic Materials

What did we learn?

• The Gaylord boxes used/purchased were too thin walled. Need

thicker walls (↑$$)

• Fuel Prices are considered to be at a low. Cost of program would be

impacted by increased fuel prices. (↑$$)

• Seeing a reduction in tonnage received (↑$$)
• Full scale program would likely result in logistical issues.
• Relies on being part of a backhaul.
• Focus on preventative maintenance on glass crushers (↓$$).
• Very abrasive material.
• Have wear parts on hand at all times.
• Minimize downtime.
• Likely will not need as large of a machine, as was thought (↓$$)

What are we doing now?

• Continue to crush glass with current machine (2003)
• Material is provided free of charge to residents for

landscaping .

• Material is rounded, therefore, safe to use around pets and children.
• Growstone is no longer an end market for the material, at

this time.

• City of Albuquerque has a new system in place.
• Any material not sold or used by local residents, will be

beneficially used as protective cover/drainage layer material.

• Continue to evaluate our processing programs to reduce

costs (long term).

SCSWA Glass Recycling Program

• Program launch date April 27, 2014
• Glass Gator demonstrations
• Began collecting glass from public
• Two drop-off locations:
• 2855 W. Amador Avenue
• 555 S. Sonoma Ranch Blvd.
• Color separated:
• Blue, Green, Amber and Clear
• Glass Pulverizer Scheduled to be delivered in

late July

• Capable of processing 5 ton/hour
• Expecting between 1500 – 2000 tons/year
• Target is collecting approximately 1000 lbs./day

Concerns from Customers

What can be placed in SCSWA Glass Containers?

• Glass jars and bottles separated by color - ONLY
• No glass vases, glass drinking cups, window glass,

Pyrex, light bulbs or test tubes.

• No lids of any kind

Do you have to clean out glass bottles before recycling?

• This is a recommended to make things easier on

the handlers. If glass has sugar remains, it becomes sticky when it dries and is more prone to attract bugs. Why is glass not being collected curbside?

• Friedman Recycling Company runs the curbside

recycling program. They do not accept glass because it causes damage to their sorting machines.

Is Glass Cullet Dangerous?

• 3/8 inch and finer glass will

not have rough edges due to the screening process.

• It is considered just as safe

as rock or gravel.

Some Concerns with Glass Recycling

• Contamination and color

mixing

• Residents frequently place the

wrong color into compartments

• r place items that are not glass

bottles and jars into containers.

• Inability to service glass as a

part of commercial programs.

• Glass sand (1/8” aggregate)

unpopular with residents; limited outbound movement

SCSWA’s Glass Program Keys to Success

• Worked with Target store to

discontinue acceptance of glass.

• Branded media and outreach for

the program.

Current Uses and Available Markets

• SCSWA offers crushed glass

free of charge to residents.

• Most residents use the cullet

for landscaping.

• Landscaping for parks and

public use

• Total tons collected and

beneficially used:

Year Tonnage Collected Lbs. Collected 2014 100 200,000 2015 232 464,000 2016 270 540,000

Residential Landscaping

Commercial Landscaping

Why and RFP for Crushed Glass?

• Potential economic development and review of

alternative markets.

• Pipe bedding
• Foam glass (Growstone/Foam Insulation)
• Landfill daily cover
• Sand Blasting
• Material management during low season
• Interest from commercial communities for crushed

cullet.

• Avoid use of cullet as alternative daily cover for

Corralitos.

• Alternative outlet for material once large

landscaping projects conclude.

Things to Consider for RFP

• Collection and Material Removal

Needs

• Vendor vs. SCSWA staff handling and

collection process

• Equipment needs: super sacks vs. trailer

collection; loaders, forklift, tarping, etc.

• Time frame for service
• Limit material quantity
• Controlled weigh-in and weigh-out

Commercial Interest: Sandblasting

• Benefits of the RFP included working with local sandblasting

company.

• Company previously imported sand from Utah.
• SCSWA provides approximately 10 tons per month of 1/8”

aggregate glass sand to vendor.

• Only 10% of the 1/8” aggregate is small enough for sandblasting.
• Vendor saves on the cost of the aggregate and importing, but has to

grind glass sand to meet need.
