It might not occur to you that a deep-sea fishing trawler can simply dump their old, worn-out fishnets over the side. After all, no one is watching them out there. And as those nets sink, they can continue to trap ocean life and stay on the ocean floor for centuries, needlessly ensnaring even more fish.

Italian textiles company Aquafil has figured out how to turn this problem into a win for the planet. Led by visionary CEO Giulio Bonazzi, the company spent years figuring out how to completely depolymerise nylon, then repolymerise it. This means they can essentially create new nylon from old, “with no loss of quality” and without the need to suck any new petroleum out of the ground. After perfecting the process, which they call Econyl, they then needed to find a readily-available source of old nylon.
