Sunflower shell is a by-product that occurs during the extraction of sunflower seeds before they are oiled or turned into flour products.
Sunflower shell, which is a light and bulky product, is often used as a fuel in oil mills due to its cost and transportation problems.
In addition, thanks to the high cellulose it contains, it is used as a filling material and roughage in the feed industry.
Sunflower shells can also be used in poultry and fish feeds.
