In ancient times, tanning was considered to be an ‘odoriferous’ trade. Tanning by ancient methods was indeed extremely foul smelling and hence most tanneries were situated in the outskirts of towns. The combined use of urine, & animal feces and the smell of decaying flesh was what made ancient tanneries so odoriferous.
The skins of dead animals were used by man even during the stone ages. Presumably as a tarpaulin or protective clothing or for the manufacture of belts or bags. Today’s leather industry however has evolved and developed just like every other profession. As with all professions, families or groups or individuals specialized in the processing of hides and skins developed over the millennia today's leather industry.
In olden times, a tannery existed in almost every place in the world. Countless buildings, streets where such activities were carried out are today named after them and serve as a reminder of the past. Many surnames of people may also have come about due to their occupation. Small tanneries are a minority in Europe these days. Most are large scale industrialised tanneries, to satisfy the global and increasing demand for leather goods.

In the earlier times, animal skins were dried and possibly smoked. But this type of preservation was no real tanning. Tanning is called the long-term preservation and irreversible process of animal skin, with or without hair with the use of tannins. Not all tanneries are equipped to carry out all the steps. Many tanneries only perform the initial part of the work and hand the rest over to a more specialized company.
In the tannery, the leather is coloured, ironed, sanded and waxed and oiled depending on the application and customer requirements.
Tanneries usually carry out their processes between slaughterhouses and the leather processing plants or leather merchants. In most cases, the tannery buys the rawhides from rawhide dealers. The prices of raw materials fluctuate, but the processing industries and leather traders want long-term stable prices. Therefore, the art of the management of a tannery is not only in the production of marketable leather, but also in making important commercial decisions. Important decisions include sourcing high-quality raw materials and establish long-term customer loyalty to the leather merchants and leather processing plants by offering a good quality product and maintaining stable prices. Increasingly, modern tanneries are also required to be transparent about their various production practices and ensuring they follow good environmental procedures in manufacturing.
