Whether you’re looking for alternatives to wool or cashmere for environmental or ethical reasons, or because you’re interested in exploring new materials, here are some options that have the best sustainability credentials: 

To Purchase:

• Weganool™
  Weganool is a wool alternative made of Calotropis fibres blended with regenerative organic cotton. It is wild foraged and hand-processed to maintain the delicate structure of the fibre. Extraction and further processing do not involve harmful chemicals.
• Vegetable Cashmere™
  Vegetable cashmere is made from the protein-based waste from soybean cultivation, has a greater tensile strength than cashmere, and has been Certified Bluesign approved.
• Hemp
  Hemp used to make Herringbone twill is 100% organic, and is biodegradable and antibacterial. It is estimated that one hectare of hemp plants absorb 22 tonnes of CO2 from the atmosphere in a year. The CO2 is converted into carbon, making hemp the greatest converter of CO2 to biomass on Earth.

Currently in Research & Development:

• Liquidwool
  Furoid are creating in-vitro hair follicles made from collagen from the stem cells of various wool-bearing animals. The process of dyeing the wool would also happen at a cellular level, which would prevent the use of the pollutive chemicals used.
