Redesigning how communities and businesses reuse and recycle glass; keep glass clean, local, and out of landfills by creating systems for source separation.

WASTE TO WORTH

Rebuilding a Broken System

In the United States, most glass enters single-stream recycling. Mixed with paper, plastics, and food waste, glass breaks in transit, becomes contaminated, its quality degrading below required standards for reuse as part of new containers.

By the time it reaches a material recovery facility, much of it is no longer usable at all —or at best is downcycled.

This is the system we are disrupting.

Cullet is built around a fundamentally different model:

Capture icon

Capture glass before it breaks or becomes contaminated

Source icon

Separate glass at the source

Local icon

Process locally

Preserve icon

Preserve manufacturing-grade quality

Extend icon

Enable reuse before recycling

The impact of today’s system is measurable. The U.S. recycles only about one-third of its glass, sending millions of tons to landfills each year—while European countries regularly exceed 80% recycling rates by relying on source separation and dedicated glass infrastructure.

In the U.S., most “recycled” glass is broken, contaminated, or discarded before it can even be crushed into cullet.

Our mission is to help transform glass recycling and reuse in the United States by building scalable systems—and shared understanding—that keep glass in circulation and out of landfills.

Cullet focuses on:

Upstream collection

Refine icon

Local processing

Prioritize icon

Reuse-first system design

Awareness icon

Education-driven behavior change

Rather than fixing broken glass downstream, we work with households and businesses to separate glass into its own stream from the start. Disciplined, systematic separation enables clean, reliable feedstock suitable for high-quality recycling and reuse.

That upstream shift changes everything: it replaces a disposal-driven system with a manufacturing-grade supply chain for glass.

Education is foundational to this shift. We work to help communities recognize glass and other municipal waste streams as untapped resources for durable materials with long-term value, not as trash. Our education efforts include:

Cullet’s long-term infrastructure model prioritizes:

Local, LEED-certified processing facilities

Reduced transport emissions

Regional manufacturing support

Local job creation

Local job creation

Because glass is heavy and costly to transport, the most effective systems are inherently local. Processing glass near where it is used and collected keeps material value in the community, supports regional manufacturing, and creates durable local jobs—while avoiding the emissions and costs of long-distance hauling.

Our vision supports two complementary outcomes.

Reuse comes first, extending the life of bottles and containers and reducing the need for energy-intensive remelting.

Recycling follows, producing high-quality cullet suitable for container-to-container glass manufacturing. Both depend on one essential principle: glass that is separated, protected, and treated as a resource.

Education enables both.
