Products made out of synthetic fibres can take 30 – 40 years to degrade, while wool degrades in a fraction of that time. This is because wool is made of keratin, a natural protein similar to the protein that makes up human hair, which can be broken down naturally without causing an environmental hazard.
Natural fibres biodegrade naturally in soils and aquatic systems, so they don’t accumulate in landfill and oceans. So whilst wool will still shed fibres during washing, these fibres will break down naturally, without causing any harmful effects to the environment.
Wool will also reduce waste to landfill as it decomposes in soil in a matter of months or years, slowly releasing valuable nutrients back into the earth
