Organic yarns are ecofriendly as they are produced according to industry standards which require sustainable green practices in their production.
Organic wool must be harvested from animals that are hormone free and fed on organic feed. These animals must not be dipped in insecticides to rid them of pests or be crowded on over-grazed pastures.
In 2005, Canada and the United States produced 19, 152 pounds of organic wool. Think of all the sweaters you could knit!
Organic cotton is grown without the use of earth damaging chemicals, pesticides, herbicides and fertilizers. These growing practices leave the soil nutrient rich and water resources uncontaminated. India produces about half of the world's organic cotton. Syria, Turkey and China are also large producers.
Bamboo and soy yarns are the newer entrants into the world of ecofriendly fibers. The bamboo plant is known for its rapid growth after harvest which lessens the need for fertilizers and pesticides. However, the harvesting of bamboo is not regulated and the process of turning it into fiber uses harsh chemicals.
Soy yarn is produced from the waste products of tofu making which is why it is seen as an ecofriendly yarn. However, there are environmental issues with the production of soybeans.
Then there is the issue of the dyes used to color these yarns. Buy yarns in the color naturally produced by the the animal or the plant. You may also buy yarns dyed with environmentally friendly dyes.
Yes, these ecofriendly yarns are more expensive and may be seen as a luxury. But, choosing wisely for your yarn stash helps mother earth. Happy yarn shopping.
