What services does Cullet provide?

Cullet provides glass recycling pickup in the Cleveland and Akron, Ohio metropolitan areas for:

  • Commercial: restaurants, bars, wineries, breweries, distilleries, and hospitality groups
  • Curbside: residential and community curbside collection
  • Group partnerships; drop-off access points at offices and schools
  • Special community events, weddings, music festivals, and more

Our approach keeps glass separated, processed locally, and prepared for high-quality recycling while building toward regional reuse systems.

What types of glass can be recycled?

We accept most container glass of any color, including:

  • Beer, wine, and spirits bottles
  • Water and beverage bottles
  • Food jars and containers
  • Perfume and cosmetic glass
What glass cannot be recycled?

The following materials are not compatible with container-glassrecycling:

  • Ceramics and dishware
  • Light bulbs and fluorescent tubes
  • Mirrors and window glass
  • Cookware (e.g., Pyrex)
  • Tempered or laminated glass
  • Lead crystal

These materials melt at different temperatures or contain additives thatdisrupt manufacturing.

Do I need to rinse, remove labels, or sort by color?

No. Labels and caps can remain on. Containers should be empty andreasonably free of food residue but rinsing and color sorting are not required.

Where does the glass go after collection?

Separated glass is sent to regional processors where it is:

  • Sorted (often by color)
  • Cleaned
  • Crushed into cullet

High-quality cullet is then used to manufacture new bottles and jars.Lower-quality material may be used in secondary applications for fiberglass construction and landscaping.

What is cullet?

Cullet is clean, processed recycled glass used as a manufacturing input.

It melts at lower temperatures than virgin raw materials and can replaceup to 95% of the raw inputs used in container production. Every 10% increase inrecycled glass content can reduce furnace energy use by approximately 2–3%,lowering emissions and improving efficiency.

Why is glass separation so important?

When glass is mixed into single-stream recycling, it breaks and becomescontaminated before it reaches a processor. This reduces its ability to becomenew bottles.

In the U.S., only about one-third of glass containers are recycled,largely due to contamination and system design. Countries with dedicatedseparation systems routinely exceed 80% recycling rates.

Separation is the difference between waste and manufacturing-gradematerial.

Is recycling enough?

Recycling is essential, but it is not the highest circular outcome.

Even the best recycling systems require crushing and remelting, whichconsumes energy and emissions. Recycling keeps glass in use. But it stillresets the material to raw input.

The goal is to recycle better and reuse first whenever possible.

What’s the difference between recycling and reuse?
  • Recycling crushes and remelts glass to make new containers.
  • Reuse keeps bottles intact so they can be cleaned, inspected, and refilled multiple times before remelting.

Reuse preserves the energy, labor, and material already embedded in thecontainer. It represents the highest circular value for glass.

Recycling is recovery. Reuse is preservation.

Why is reuse considered the ultimate circular goal?

Because the most sustainable bottle is the one that already exists.

When a bottle is reused:

  • It avoids energy-intensive remelting
  • It avoids raw material extraction
  • It extends the useful life of the container
  • It reduces total packaging production

In a circular system, reuse comes first. Recycling follows only when acontainer reaches the end of its usable life.

Is bottle reuse still possible in the U.S.?

Yes — but large-scale refill infrastructure largely disappeared assingle-use packaging became dominant.

Modern reuse requires rebuilding systems for:

  • Standardized bottle formats
  • Reverse logistics and collection
  • Industrial washing and sanitation
  • Inspection and quality control
  • Crate pickup and return

These systems require coordination across producers, hospitality groups,municipalities, and households.

Cullet’s long-term objective is to help reestablish reuse infrastructureregionally — so bottles remain in circulation at their highest value beforeever becoming cullet.

Why process glass locally?

Glass is heavy and expensive to transport long distances.

Local collection and processing:

  • Reduce hauling emissions
  • Lower logistics costs
  • Strengthen regional manufacturing
  • Retain economic value within communities

Circular systems work best at regional scale.

Is glass infinitely recyclable?

Yes. Glass can be recycled endlessly without losing purity or performance when recovered cleanly.

The glass bottle you recycle can go from your recycling bin back into a new bottle in as little as 30 days.

How can households and businesses participate?

Glass performs best when treated as a resource — not waste.

  • Keep containers intact where reuse is possible
  • Separate glass
  • Participate in collection
  • Support return systems
