Sorted Fiber Material from Textile Waste

FiberFlow separates mixed post-consumer textiles into clean, material-specific fractions - polyester, cotton, polyamide and more - ready to feed directly into your recycling process.

About

Recycling starts with the right Feedstock.

Post-consumer textiles arrive as mixed-fiber blends – polycotton, polyester-polyamide, and other multi-component composites. Chemical, thermo-mechanical and biological recycling processes require feedstock within tight compositional tolerances, and manual garment sorting cannot deliver that. FiberFlow separates textile waste at the fiber level, giving your process the purity and consistency it needs.

Our Products

Six Materials,
One Process

You bring the recycling expertise – we deliver the feedstock. Here is what sorted fiber fractions can enable.

Cellulose

Short-staple cotton fibers with high specific surface area. Suitable for lyocell production, enzymatic hydrolysis, and other surface-sensitive processes.

Polyester

Polyester fibers suitable for chemical depolymerization, glycolysis, and thermo-mechanical reprocessing into pellets.

Polyamide

Polyamide fibers suitable for hydrolytic and aminolytic depolymerization as well as thermo-mechanical recycling.

Acrylic

Acrylic fibers suitable for melt-spinning or chemical recycling.

Polypropylene

Polyolefin fibers suited for thermo-mechanical recycling and melt-spinning into new fiber or nonwoven applications.

Elasthane

Elastane fibers suitable for chemical recycling processes.
