It’s people! They really should name the product “soylent wool” 😀
Wendelin Stark would like a new sweater. It’s cold in Zürich, where he lives, so he’d like a really warm one. Preferably one as cozy as cashmere.
Before long, Stark may be wearing one of his own invention, crafted with an ultra-soft wool-like yarn spun from all the stuff that’s left after an animal’s been slaughtered and processed. His team at the Functional Materials Laboratory at ETH Zürich, where he’s a professor, has spent four years creating such a fabric, and recently created a working prototype—of a mitten.
My preferred use for animal by-products is petroleum production. There was news years ago about someone who’d pioneered a contraption to produce petroleum/oil from chicken carcasses, wanting to employ them near chicken farms. I doubt it would be enough volume to fuel vehicles, but given the hurdles that the gelatin wool still has to address – petroleum production for textiles that already work would be a better use of resources to me. We are more dependent on petroleum products than we’d like to admit.
