Sheep wool

Wool is a natural, protein staple fiber that has been used to keep people warm for over 10’000 years despite European wool manufacturing only starting around 1900 BC.

Wool is obtained by shearing sheep, usually in spring or summer and as there are over 200 different breeds of sheep worldwide, quality and touch differentiate, reaching from the softest merino to the rather coarse lincoln.

Wool is often treated with extensive amounts of chemicals to remove wool grease and pests and are often bleached additionally.

Sheep flocks can have quite a negative impact on the environment due to overgrazing, excreta, and pesticide release, which are derived from sheep’s coats, where they have been sprayed on for protection. Furthermore, wool production is an energy- and chemical-intensive process.

Wool is best recycled at the end of its life cycle.

Animal cruelty is a significant issue when it comes to sheep wool. A practice often performed on sheep is mulesing. Mulesing is the practice of the brutal removal of skin around the anus for the protection from pests.
