In a recent post, I filled you in on the recent history of glass recycling problems in Chattanooga. One of my concerned readers contacted me, asking me to confirm what I had written: that the glass we bring to the recycling centers in Chattanooga may not be getting recycled. I have since been able to confirm that glass brought to the recycling centers in Chattanooga IS getting recycled.
How did I find out?
The answer was not obtained through the City of Chattanooga’s Recycling Department, nor WestRock, our Materials Recovery Facility (MRF). No one from the City even referred me to the right person or company. I was able to speak to the Vice President of Marketing & Communications at Strategic Materials, Laura Hennemann, last week, and she confirmed that glass from Chattanooga’s recycling centers goes directly to their Atlanta facility and is recycled.
Strategic Materials and the Glass Recycling Coalition
Strategic Materials is the largest glass recycling company in North America, and they have nearly 50 facilities nationwide. Three of those are in Georgia. I got in touch with Hennemann by contacting the Glass Recycling Coalition (GRC), of which Strategic Materials is a member. The GRC, formed in 2016, “brings together a diverse membership of companies and organizations to make glass recycling work: glass manufacturers, haulers, processors, materials recovery facilities, capital markets, end markets and brands that use glass to showcase their products.” They encourage MRFs to become members. WestRock is not a listed member.
Strategic Materials and the Glass Recycling Coalition hope to educate everyone on glass recycling because glass is 100% recyclable. They want to educate residents and consumers, MRFs, local governments and municipalities, and solid waste haulers. They helped me so that I can help others understand the glass recycling process.
The Glass Recycling Coalition’s 2018 survey concluded that 93% of consumers still expect to be able to recycle glass, so we know it’s important to people. I don’t believe people know about the issues in recent years with glass recycling in Chattanooga. I sure didn’t until I began researching it!
Recycling is extremely complex
In general, recycling beyond the blue curbside bin is extremely complicated. It has taken me weeks to understand, and I still don’t know all of it. I also cannot summarize all of the information in one single post. Today I’ll explain our local system and how glass is processed here.
How recycling works in Chattanooga
The Public Works Department in the City of Chattanooga manages garbage and recycling curbside collection through the Solid Waste and Recycling Division. City employees operate the equipment and run the daily routes, and the City of Chattanooga owns and maintains the trucks.
We have what is termed single-stream recycling for curbside pick-up in Chattanooga. Single-stream recycling means that all recycling is mixed together in the 96-gallon blue bins, and those bins are collected by trucks who deliver the materials to our MRF, WestRock. The primary purpose of MRFs is to sort materials. WestRock takes the recycling materials, sorts them, and sells sends the materials on to the facility that purchases those materials.
WestRock is the primary MRF for much of the Southeast U.S. They are a paper recycling company first, so paper and cardboard recovery are their number one motivation when it comes to materials recovery.
I was able to confirm through the Public Works Department that the sorting from curbside used to be separated by Orange Grove, but now sorting from curbside is handled solely by WestRock. Orange Grove is still involved with the recycling centers, in that it staffs the City of Chattanooga’s five recycling centers as well as the three refuse centers.
As mentioned above, the glass that residents take to the five recycling centers in Chattanooga does get recycled! It is directly recycled by Strategic Materials in Atlanta. While residents sort glass by color at the recycling centers in Chattanooga, Strategic Materials said that this isn’t necessary because they can accept mixed color bottle glass. They have an optical sorter in their Atlanta facility, which sorts the glass by color. Chattanooga has not changed their signage or policy yet, so the separate bins at the centers remain.
Glass causes problems without the right sorting equipment
Are there solutions for the MRFs?
Despite the issues, keep trying
Glass is 100% recyclable, so don’t give up.
Glass is still a better option for waste. In a worst-case scenario, I’d rather have glass in landfills (and sometimes oceans) instead of plastic. Why? Because plastic is toxic and leaches poison that gets into water and marine life. Plastic releases chemicals known to cause cancer or other health problems. Glass does not contain these chemicals and is less harmful. So I’m going to keep purchasing products in glass over plastic every time. Especially since I don’t want chemicals from those plastics in my family’s food.
I’ll also keep taking my glass to the recycling center because I am able and willing to take the time. So I’m asking you to do the same – bring your glass to one of the five recycling centers. If you can’t do it, maybe a friend can drop yours off when they take theirs. For example, I take my in-law’s glass for them every few weeks. I’m happy to do it. What about starting a little co-op of glass recycling in your neighborhood, or at work? Everyone takes a turn, and the glass gets recycled.
