The ECONYL® yarn is a 100% regenerated Nylon yarn coming from pre- and post-consumer Nylon waste. This process, based in Slovenia (Ajdovscina and Ljubljana), is the only one of this kind on an industrial level and it was invented and developed by Aquafil S.p.A. (Italy).

It started more than 4 years ago and around 25 million Euros were invested in its development, starting with the regeneration of pre-consumer waste and later, the introduction of post-consumer components.

Pre-consumer waste can be production discards, industrial plastic components and oligomers, but it is with post-consumer waste that the big challenge comes in. Post-consumer waste is in fact waste that would otherwise be dumped in landfills or abandoned in nature with big environmental problems. With the ECONYL® Regeneration System these materials are recovered - which can be carpet fluff (the upper part of carpets), abandoned or spent fishing nets (from all over the world) - and regenerated, giving it new life and contributing to a cleaner environment.

The fishing nets come from agreements currently in place with the fish farming industry or from spent or abandoned nets that are recovered from the seas or collected through special projects with fisherman and fishing communities (Healthy Seas and Net-WorksTM). Most of the nets are received from Canada, USA, Norway, Greece, Turkey, Egypt, Pakistan and Thailand.

The other big stream is the one related to fluff (upper part of carpets) that is recovered from spent carpets, especially in the United States. (Aquafil USA, Cartersville-Georgia).

The ECONYL® Regeneration system is a unique chemical and mechanical process that allows to create regenerated yarn from waste keeping the same purity and characteristics of Nylon coming from virgin raw material. With this yarn, numerous textile products can be created with a double advantage for the environment. From one side - used in a smart way waste material that would otherwise remain wasted in the environment, and from the other side, precious raw materials are saved that are normally used in the production of Nylon.


For every 10,000 tons of ECONYL® caprolactam (the raw material used), these are the environmental benefits obtained:

  • Elimination of 12.6 thousand tonnes of waste

  • Saved 70 thousand barrels of crude oil

  • Avoided 42 thousand tons of CO2 equivalent emissions

  • Saved 865 thousand GJ on total process energy
