ACE Glass Aggregates, also known as ACEFGA, was founded with a clear purpose: to turn waste glass into sustainable building materials while cutting landfill waste and helping build a cleaner future. At the center of that mission is the company’s primary product, ultra-lightweight foamed glass aggregate, or UL-FGA.

UL-FGA is manufactured from recycled post-consumer glass through a high-temperature expansion process. The result is a closed-cell, pumice-like material that is lightweight, moisture resistant, insulating, and structurally stable. Rather than allowing discarded glass to be stockpiled or sent to landfills, ACEFGA gives that material a second life in infrastructure and construction projects.

The company’s origins were driven by both sustainability and market demand. Years ago, the founder, Courtney, Little, began looking for meaningful ways to recycle glass beyond traditional disposal or storage methods. That search led to Austria, where advanced foamed glass aggregate manufacturing technology had already been proven and used successfully in Europe.

From that experience, ACEFGA recognized a major opportunity in the United States. As infrastructure owners, engineers, departments of transportation, and contractors look for more sustainable and high-performance materials, foamed glass aggregate offers an alternative that meets both environmental and engineering needs.

Demand has grown steadily because UL-FGA provides several advantages over traditional materials. It is

• lighter in weight,
• easier to transport,
• moisture resistant,
• insulating,
• environmentally sustainable, and
• structurally stable.

These qualities make it especially attractive for projects where reducing load, improving drainage, or simplifying installation can have a major impact on cost and performance.

While traditional aggregates may sometimes appear less expensive upfront, foamed glass aggregate can create substantial project savings. Its lighter weight can reduce structural loads, lower transportation costs, improve drainage and insulation, and speed up installation. In some cases, UL-FGA can eliminate the need for more expensive engineered alternatives entirely.

One example is the I-30 project in North Little Rock, where UL-FGA was used to cover utilities. Other solutions would have required structural concrete encasement or bridge construction. By using UL-FGA, the project team found a more cost-effective solution that saved significant time and money.

ACEFGA is seeing strong interest in a wide range of specialty applications, including

• roadway and highway base construction,
• lightweight fill, geotechnical stabilization,
• retaining wall backfill,
• drainage systems,
• roofing systems,
• green infrastructure,
• flood mitigation, and
• sustainable commercial construction.

ACEFGA’s foamed glass aggregate is designed primarily for performance rather than appearance. Its value lies in its engineering benefits, sustainability, and ability to solve difficult construction challenges.

Looking ahead, ACEFGA sees foamed glass aggregate moving well beyond a niche market. As the construction industry places greater emphasis on sustainable infrastructure, lower-carbon materials, landfill diversion, and circular economy practices, adoption of recycled glass aggregate is expected to grow nationwide. Similar technologies have been used in Europe for decades, and the U.S. market is now beginning to scale.

By transforming post-consumer glass into a lightweight, durable, and sustainable building material, ACE Glass Aggregates is helping redefine what waste can become — and giving contractors, engineers, and infrastructure owners a practical tool for building smarter, cleaner, and more efficiently.
