How sustainable is
Silk
?
Silk is a protein fiber spun by silkworms. It is a renewable resource and also biodegradable. However, chemicals are used to produce conventional silk, so organic silk or Oeko-Tex certified silk is always a better option.
Because conventional silk production kills the silkworm, animal rights advocates prefer “Peace Silk”, Tussah / Ahimsa silk, which allow the moth to evacuate the cocoon before it is boiled to produce silk.
Silk has been used for textiles for thousands of years and is an amazing natural delicate material.
bergstrand material GUIDE ranking*
When sourcing silk, find preferred silks that are produced with organic means that don’t destroy the moth in the process.
Preferred
Preferred materials are considered to be the most environmentally friendly, sustainable, and ethical options for clothing production. These materials are often made from natural, renewable resources, and are processed using eco-friendly methods that have minimal impact on the environment. These materials are typically more expensive than synthetic alternatives, but are considered to be worth the extra cost due to their positive environmental and ethical impact, as well as longevity.
Approved
Approved materials may be less expensive than preferred materials, but may not be as ethical or sustainable in their production. While approved materials are not considered the best option, they may be used in clothing production as long as certain standards and guidelines are followed.
