Before I did this post, I didn't know what waste the wool industry could produce.This is what I've learned...
Wool is biodegradable, unlike most synthetic fibres, and wool clothing and processing wastes are recycled into other durable forms of textile (woolen-spun knitwear, insulation). The carbon in wool comes from the pasture and the atmosphere. Wool produces more carbon then cotton.
From the shearing shed to catwalk
Researchers in Flinders University (South Australian) have develop a clean technology to get a substance called keratin out of unwanted wool.
