From Recycling Nylon to Regenerating Virgin Material: ECONYL [Video]

The secret’s out on plastics recycling: generally, they get “downcycled” into a lesser material that can’t be further recycled. Getting more use out of that plastic is certainly beneficial, but they’re not recyclable in the way, say, glass and aluminum are.  That’s a problem not only because new plastics inevitably means drilling for more oil and natural gas, but also that the used material will eventually end up polluting a natural system somewhere.

We’ve seen one example already of a process meant to make recycled plastics recyclable. It turns out that recycling nylon – a “thermoplastic” – has also received an upgrade: carpet fiber manufacturer Aquafil has developed what it describes as a “regeneration” process for nylon 6. Take a look at the company’s video for its ECONYL regeneration system:

OK, “miracle” is perhaps a bit strong, but the company has created something pretty impressive here.  Global demand for fiber is expected to grow by 30% between 2010 and 2020, and without processes like this, we’re going to have drill for a lot more oil and natural gas (the feedstocks for most synthetic fibers). Given the current state of plastics recycling, that likely means a lot more plastic pollution in landfills, waterways, and oceans. So, figuring out a way to make a widely used plastic material endlessly recyclable like glass and aluminum is a definite step forward.

So far, this process is only available for nylon 6 (the slightly less-durable cousin of nylon 6,6), and involves a combination of pre-consumer and post-consumer wastes. But nylon 6 is widely used in textiles, threads, nets, and ropes, and the company has increased the amount of post-consumer “regenerated” nylon in the ECONYL product from 30% in 2012 to 50% currently… so this process has the potential to make a significant difference. Additionally, the process of creating “virgin” nylon through this system reduces the resources needed and wastes produced to make the material: ECONYL processes reduce the energy needed to produce the raw material caprolactam by 54%, and the greenhosue gas emissions released by 55%.
