You know how it goes – we South Africans like a bit of braaiing, a cold drink, and finding creative ways to repurpose the things that would normally end up in the trash. Well, Eddie Wang, a guy from Taiwan, is taking that to a whole new level by turning discarded oyster shells into a fancy new fabric called Seawool.
Growing up in Yunlin, a town known for its oyster farming, Eddie noticed that locals were using oyster shells as insulation for their homes. They’d burn the shells and use the residue on the walls to keep their homes cool in summer and warm in winter. Intrigued, Eddie, who already ran a textile company, began experimenting with turning those shells into something usable – a fabric that feels like wool, but without the wool.
Fast forward to 2013, and Eddie’s company, Creative Tech Textile, cracked the code: a fabric made from ground-up oyster shells mixed with recycled plastic bottles. This “magical yarn” has become a hit with outdoor and sustainable clothing brands in Europe and the U.S.
Here’s where it gets interesting for us – Taiwan, which has an insatiable appetite for oysters (we’re talking 200,000 tonnes a year), discards about 160,000 tonnes of shells annually. These shells used to cause a stink (literally), but Eddie and other innovators are turning that waste into something profitable, with his Seawool generating over $6 million a year.
Now, the oyster shells are ground into tiny beads, combined with recycled plastic, and voila – you get Seawool, a fabric that’s not just eco-friendly but also low-carbon because it doesn’t require water to make. It’s pretty much the green dream, wrapped in a jacket or sweater.
Even Taiwan Sugar Corporation (yes, sugar) is getting in on the action, grinding up shells to make incense sticks that burn cleaner and with fewer harmful chemicals.
From waste to gold – Eddie Wang and his Seawool are proving that the best things in life really do come from the sea… and a little bit of creativity.
