Byproducts

Several by-products occur during the production of grain and split leather. These by-products are partly further processed by BOXMARK or sold to various industries as processed products.

The Split Neck

The so-called split neck comes from the bend production which again is processed to split leather. BOXMARK mainly sells this split neck for sausage skin production on a collagen fiber basis.

The Split Belly

The so-called split belly, which is primarily used for gelatine production, is another by-product that comes from butting split skin.
