More and more manufacturers are concerned about sustainability and the circular economy, with the aim to reduce their impact on the environment through better waste management. Based on the observation that the textile value chain is a major contributor to landfills, where most clothing ends its life, DOMO has developed NYLEO® 4EARTH®, a new fiber with enhanced biodegradation when landfilled. A traditional polyamide 66 fiber decomposes in about 50-100 years. NYLEO® 4EARTH® with enhanced biodegradability decomposes in under five years.

The pollution generated by the textile industry has a huge impact on the planet. 

According to the Ellen Mac Arthur Foundation, more than 70% of end-of-life clothing is landfilled or incinerated. Based on this observation, DOMO has developed NYLEO® 4EARTH®, using the Amni Soul Eco® technology* from the Solvay Group, which demonstrates enhanced biodegradation when landfilled. In anaerobic landfills, its unique composition allows bacteria to gain access to and digest the waste materials, thus accelerating the biodegradation process. 

*Amni Soul Eco® technology is part of a new generation of sustainable fibers manufactured using environmentally-friendly processes. 

Key benefits of NYLEO® 4EARTH® polyamide 6.6 fibers

NYLEO® 4EARTH is the right choice for both the environment and your products. By offering enhanced biodegradability to safeguard the environment while maintaining all the standard characteristics of polyamide 6.6, including durability, long life, high tenacity, soft touch and abrasion resistance, it’s the optimal solution for your final applications.

Whether it is spinning, drawing, knitting, dyeing or finishing, NYLEO® 4EARTH® can undergo many types of processing and is the perfect solution to create high-quality and eco-friendly products respecting the environment.

Why you should choose NYLEO® 4EARTH®

NYLEO® 4EARTH® reduces the environmental impact of polyamide fiber based-products to levels never before achieved.  

As demonstrated by independent laboratory biodegradation tests in accordance with D5511-12 (anaerobic - high solids biodegradability), NYLEO® EARTH® fibers biodegrade in around five years when disposed of in landfills, compared to more than 50 years for traditional polyamide 6.6 fibers. ​ 

Biodagradation of NYLEO® 4EARTH®

Like other biodegradable products, once landfilled, NYLEO® 4EARTH® polyamide 6.6 fiber with enhanced biodegradability breaks down into organic matter (biomass) and biogas (methane). ​ 

Within five years, more than 90% of the fiber is converted into biogas, with the remainder as biomass residues.​ Moreover, in well controlled landfills, methane is not released directly into the atmosphere, but burned or reused for power generation.

Key applications and industries

DOMO’s goal with NYLEO® 4EARTH® is to provide sustainable and added-value solutions for the textile, flock, nonwovens and carpet markets which are increasingly mindful of production ethics and eco-sustainable approaches.  

To be more sustainable, manufacturers will need to redesign production to make it easier to manage the end-of-life of products and waste.

The revolutionary NYLEO® 4EARTH® technology provides a new industrial perspective reducing to a minimum the impact on nature and making the world a better place for future generations.
