Yarn producer Aquafil has designed the Econyl system, which enables Polyamide 6 or Nylon 6 waste to be manufactured into new Nylon 6 with no loss of quality. Key to success is the Reclaiming Programme, an essential tool to facilitate a reverse supply chain and ensure reliable materials inputs.
Aquaﬁl Group have a strong heritage in effective resource management, in making rigid fabrics for use in carpet tiles. For over twenty years, the company have been working on re-processing BCF(carpet yarn), and CEO Giulio Bonazzi says that "without realising it we have always developed technologies that are very advanced in terms of environmental concerns…and looking at business in a circular way has opened up new opportunities for innovation”. De-polymerisation through the Econyl process is the next logical step for Aquaﬁl. However, there is a tendency to overplay the link between ‘innovation’ and technology, when in fact the company are realising the beneﬁts of a closed loop model right now, without relying on radical jumps in technology, or waiting for a revolutionary ‘silver bullet’ for the textiles industry.
We realised that Nylon 6 has these peculiarities, it can be depolymerised, and once this has been done with strong puriﬁcation, then we can produce a product with exactly the same characteristics of the polymer coming from crude oil. We were lucky to be part of this system already, but we have invested money to develop technology that supports it.
As Nylon 6 is already able to be depolymerised and repolymerised with no loss of quality, the challenge has been accessing a reliable feedstock for this process. To this end, Aquaﬁl established the Econyl Reclaiming Programme, an essential tool that the company is putting in place to facilitate a reverse supply chain and ensure reliable materials inputs. The programme not only enables clients to return their end of use products, but sources a variety of products made entirely or partially of Nylon 6, such as ﬁshing nets, rigid fabrics, clothes at the end of their life cycle, or other plastic components. The company’s thinking has shifted – what used to be thought of as waste is now food for their industrial process.
