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 nylon 66 fiber decomposes in about 50-100 years. NYLEO® 4EARTH® with enhanced biodegradability decomposes in under five years.

As all the industries embrace sustainable development concerns, regulatory push and economic pull are driving manufacturers to seek ways to reduce their impacts on the environment and decreasing the amount of waste left to future generations.  

The pollution generated by the textile industry has a huge impact on the planet. In recent years, the average number of items of clothing purchased annually by individuals has increased drastically, ultimately leading to major environmental problems, such as water, air and solid waste pollution.  

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, using the Amni Soul Eco® technology* from the Solvay Group, NYLEO® 4EARTH®, 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 best choice offering an enhanced biodegradability to safeguard the environment while maintaining  all the standard characteristics of nylon 6.6 such as durability, long life, high tenacity, soft touch and abrasion resistance to your final applications.​  

Spinning, drawing, knitting, dyeing, finishing, NYLEO® 4EARTH® can undergo different 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 5 years when disposed of in landfills, compared to more than 50 years for traditional nylon 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). ​ 

In 5 years, more than 90% of the fiber is converted into Biogas. Residues are biomass.​ 

In well controlled landfills, methane is not released directly in the atmosphere, but burned or reused for power generation. 

Key applications and key industries

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

As 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 impacts on nature and making the world better for future generations.
