Introducing

SUSTAINA® LOOP

Manufactured from a combination of post-industrial circular glass fibers and traditional glass input materials, SUSTAINA® Loop is just one of our efforts to protect the planet without compromising product performance.

Send us your waste

We combine glass fiber waste with traditional input materials to produce SUSTAINA® Loop. The output becomes a new glass fiber product made with the sizing of your choice such as PULSTRAND® 4100. Reach out to an expert to get started.

Designed to Power the Products You Already Know and Trust

From operational efficiency to part performance, everything stays the same.

¹Via mass balance approach

what is mass balance?

Sustainability isn’t about reinventing everything overnight. It’s about making measurable progress towards circularity.

That’s where mass balance comes in. For us, mass balance means gradually integrating circular glass fibers into our production processes while ensuring transparency and accountability. 

We’re scaling up this approach with SUSTAINA® Loop.

Discover how SUSTAINA® LOOP is made

Waste ≠ trash

The process starts with the simple recognition that glass waste is not trash.

We found a way to reclaim glass waste, so it doesn't go straight to the landfill.

Quality Ensured

The glass goes through a recovery process that ensures the right characteristics and performance.

After meticulous testing and analysis, it is ready to be remelted and transformed into fiberglass again to create our Type 30® products.

Superpower added

SUSTAINA® Loop glass fibers are then sized to match the performance and characteristics of your product of choice.

What ARE CIRCULAR GLASS FIBERS?

Circularity considers the entire life cycle of a product. When we make SUSTAINA® Loop, we aim to limit material extraction and reduce waste to landfill while maintaining performance. Circular glass fibers reintroduce customer glass waste back into the loop.

For us, it is vital that we keep every material in the loop at its highest value.

SUSTAINA®

In addition to SUSTAINA® Loop, we offer SUSTAINA® corrosion-resistant glass made with up to 100% circular content in the following products:

Sustainability has

always been our business

From the materials we design to the products we help build, sustainability informs everything we do.

In 1938, we created E-glass, which helped pave the way for some of the lightest and strongest materials on Earth.

In 1997, we launched Advantex®, a technology with enhanced corrosion resistance, and increased service life.

In the 2000s, we brought H-Glass to life, a high-modulus platform specially designed for the production of longer, lighter wind turbine blades. 

Now, it’s time for another leap in how we are addressing industry issues.
As always, together.

Because it all adds up to make a world of a difference.
