But how can fur be sustainable when tanned and collared? The production of the fur has been mentioned earlier, and can be nothing other than a sustainable process. The tanning and coloring are gentle processes and techniques that preserve the quality and strength of the fur. The main chemicals used are actually rather familiar, these are water, salt, alum, sawdust, cornstarch, lanolin and other natural ingredients. Regulations and environmental controls ensures that there are no harmful effluents. An important factor in terms of sustainability is the production and use. Because some animals are produced only for their pelts. Fx minks is a great example. Farmers in EU is striving towards complete animal use. The skin is used for clothes and the rest is used for either cosmetics, biodiesel or other recycling purposes. The same is the case with fx. Rabbits. Rabbit fur is also farmed, but mainly for the purpose of food. Instead of throwing the pelt away it is used to make fur products of, which enable farmers to use 100% of the animal for sustainable purposes.
