Recycled Wool
Recycled wool is also very sustainable option. Apart from diverting used wool garments from landfills, it saves a considerable amount of water, reduces land use for sheep grazing and avoids the use of chemicals for dyeing.
Recycled wool contributes to a reduction of air, water, and soil pollution.
Few certification labels exist to ensure consumers that wool is really recycled, such as Global Recycled Standard (GRS).
