Nereus® Bio Fibers


Nereus® Bio is an advanced additive technology designed to accelerate the breakdown of polyester under specific environmental conditions. It retains the reliable performance and durability of conventional polyester while supporting responsible end-of-life solutions.

Nereus® Bio is a next-generation formulation that enables polyester to biodegrade more rapidly in specific environments such as ocean water or landfill. It provides a controlled end-of-life option that helps limit the accumulation of persistent microplastics and contributes to reducing long-term environmental impact.

Automotive

Wide range of automotive applications, including engine compartments, headliners, and interior components. They meet the automotive industry’s requirements for quality, acoustics, safety, and environmental standards.

Home & Apparel

High-performance biodegradable hollow and solid fibers developed for the bedding and apparel industry. Suitable for needlepunch, thermobonding, and fiberfill applications—combining durability, comfort, and innovation
Staple fibers for fiberfill

Fiberfill

The three-dimensional crimp structure, combined with a hollow core, provides excellent resilience and enhances insulation in the final product. Hollow conjugated polyester fibers (HCS) and solid fibers are commonly used in fiberfill applications.

Nonwovens

Broad portfolio of Bio PET staple fibers developed for wipes used across various sectors—including electronics, printing, pharmaceuticals, cosmetics, medical care, patient hygiene, and general cleaning.
Spun yarn - open end spinning

Spinning

Polyester staple fibers suitable for worsted, open-end, and conventional ring spinning processes.

FAQ

Can Nereus® Bio be recycled?

Yes, Nereus® Bio can be chemically recycled and fits perfectly in a circular lifespan, and Nereus® Bio maintain a 95% yield rate through the chemical recycling process.

How does Nereus® Bio work with EU’s single-use plastic directive?

Polyester is a polymer, and therefore the end product could be considered as a “plastic”. This means that different measures from Single-Use Plastic Directive can be applied to your product.

Will Nereus® Bio biodegrade during usage?

Again, it’s a no. Nereus® Bio fibers in products do not biodegrade during usage. Only microplastics that leave products ending up in landfills or oceans will biodegrade, so there really is no special care required.

Does Nereus® Bio require a change in production set-up?

No, Nereus® Bio has the same characteristics and performance as regular PET fibers with the same output and same whiteness, and it blends well with natural fibers.

Will Nereus® Bio biodegrade on shelves?

No, Nereus® Bio only biodegrades in environments with naturally occurring microbes, such as landfills, oceans, and wastewater. Nereus® Bio comes in normal bales and has a normal shelf life with no need for special care or treatment during storage and transportation.

Can Nereus® Bio be used for my products?

Nereus® Bio can be added to any type of polyester and fabric fiber, from wadding, filtration, and automotive to acoustics, medical, and hygiene products.

How can we be sure it works on our set-up?

Before initiating full production, a sample is sent to 3rd party lab for an accelerated test that measures the initial behavior of the fiber. After the QC test for up to 90 days, we can verify that the technology works, and the staple fibers are approved.

Is Nereus® Bio available today?

YES! Nereus® Bio is already available from several locations worldwide, both virgin and recycled from a controlled supply chain. There is full capacity and delivery guarantee. And that’s why we can start fixing polyester right now.

Is Nereus® Bio scalable?

Yes, we are already commercial with BICO (low melting fibers), solid, and hollow fibers – and have no capacity issues.

How does Nereus® Bio work?

Polyester is a complex molecule that naturally occuring microbes have a hard time digesting, why standard polyester does not biodegrade. Nereus® Bio optimizes the polyester or fabric fiber with a simple sugar, making the fibers easier and more pleasant for microbes to digest. Essentially, we make your fiber a Boston Cream Donut for microbes.
