Nereus Bio® - Let's Fix Polyester

Let’s fix polyester together

Nereus® Bio by

Any company depending on polyester knows that to future-proof the business, we must speed up the transformation of the production, to reduce the climate footprint and consumption of polyester.

Nereus® Bio technology enables polyester and fabric fibers to biodegrade* and return to nature. Join us in fixing polyester.

Polyester is no longer invincible Nereus® Bio is an additive technology that enables polyester and fabric fibers biodegrade* in the environment. A revolutionary breakthrough that offers a previously unattainable level of performance and biodegradability, reducing microplastics in our landfills and oceans, Nereus® Bio is a first-of-its-kind technology and represents a critical component to a product’s lifecycle – a safety net should the product shed during laundering or end up in a landfill. It is simply designed to return to materials found in nature.

Nereus® Bio has been specifically designed to biodegrade* in the environments where the vast majority of plastics eventually find themselves: landfills and ocean water. According to independent testing, Nereus® Bio reached 93.8% biodegradation* in 646 days when exposed to an accelerated landfill environment. At the conclusion of this test, the remaining material was found to contain no trace of plastic, leaving behind only natural, carbon based elements! And what is even better, additional independent testing concluded that the soil left behind remains perfectly suitable for plant growth.

With no time to waste, let’s fix polyester!

How Nereus® Bio returns to materials found in nature Nereus® Bio is specifically designed to reduce plastic waste in the environment and microplastics in our oceans.

Nereus® Bio has been optimized to be more attractive to naturally occurring microbes found in landfills, oceans and waste water. When Nereus® Bio is exposed to these specific surroundings, it will break down over time into natural components: water, CO2, methane, biomass and humus – a common component of potting soil. And Nereus® Bio will do so at a dramatically faster rate than standard polyester.

Microplastics Recycling alone is not enough. Polyester and fabric made from biodegradable fibers combats plastic waste at the material level.

This process breaks down polyester to its basic components so that it can be rejuvenated into a new high-performance material, without compromising its original integrity.

Nereus® Bio makes it easier for microorganisms to consume plastic, resulting in full biodegration*.

Let’s make microplastic a micro problem When left in active microbial environments such as landfill or ocean water, Nereus® Bio will hydrolyze and biodegrade.

This efficiently minimize micro plastic pollution, unlike OXO or UV degradation that creates micoplastics in the presence of oxygen and sunlight and does not biodegrade.

FAQs

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.

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.

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.

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.

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.

Is Nereus® Bio scalable?

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

Will Nereus® Bio biodegrade on shelves?

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

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.

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.

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.
