Recovery of raw material for nylon

Q: What is your technology?

Econyl Regeneration System is an industrial process for the production of nylon 6 from 100% regenerated caprolactam, planned and implemented by Aquafil.

Q: How does it work?

Econyl was introduced in 2011 to produce Econyl caprolactam from pre- and post-consumer waste

such as fishing nets, fluff and plastic components through an internally developed chemical and mechanical process.

Q: Where would it ideally be used?

Econyl fibre can be used in many applications: textile flooring; car mats; plastic components such as dashboards and door handles; and clothing.

Q: How is it different?

With endless regeneration possibilities, it is able to drastically cut the production of new waste and the consumption of fossil fuels.

Q: What are the benefits?

Econyl Regeneration System enables the production of high-quality regenerated caprolactam while minimising environmental impact. Every year, around four million tonnes of nylon 6 products are made and most of them end up in incinerators or landfill.

Q: Cost?

The first Econyl plant was opened in May 2011 in Ljubljana, Slovenia, with a total investment of more than e17m (£13.8m) and after four years of development, design and construction.

Q: Any savings?

One tonne of caprolactam is produced with about seven oil barrels, so the economic and environmental savings generated from 10,000 tonnes of regenerated Econyl caprolactam can be quantified as around 70,000 oil barrels.

Q: What about maintenance?

Aquafil has created different in-house teams that operate for the maintenance of our Econyl plant.

Q: How is it future-proofed?

Econyl is fully compliant with present legislation and strongly oriented towards the future, going beyond the standards set for the industry. Aquafil has also created the Econyl Reclaiming Program with the aim of expanding the network of collection of waste materials to feed the process.

Q: How many tonnes have you sold and where?

In the first half-year of 2012, we sold about six million tonnes of Econyl products.
