Is wool bio degradable?

Natural fibres such as wool are biodegradable. They do not accumulate in the environment but breakdown naturally to harmless compounds.

Wool is 100% natural protein fibre. Every year sheep produce a new fleece making it a renewable fibre source. At the end of its useful life it can be returned to the soil where it will start to decompose in a very short time, where as most synthetics are extremely slow to degrade. For example, garments made out of polyester and nylon take about 40 years to degrade, whereas those made of wool take only one year. A biodegradable product can be broken down by a biological process (bacteria and fungi) into natural raw materials, carbon dioxide, water and naturally occurring minerals.
