All About Leather Tanneries: Q&A with Leather Tannery Manager Nasir

What is a Leather Tannery?

A leather tannery is a facility where animal hides are processed to create leather. The process involves treating animal hides with chemicals and natural materials to covert them into durable, flexible, and non-perishable leather. Without the tanning process, raw animal skins would decompose and rot quickly when wet or dry out into a hard, brittle material. Tanning alters the protein structure of the skin (collagen) so it remains soft, durable, and resistant to decay.

What happens inside a Leather Tannery?

Inside a leather tannery, raw animal hides are processed and transformed into leather through various stages of cleaning, tanning, dyeing, and finishing. The process typically involves the following steps:

1. Soaking: The raw hides are soaked in water to remove impurities.

2. Fleshing: The hides are then de-haired and de-fleshed to prepare them for tanning.

3. Tanning: The tanning process involves treating the hides with tannins to stabilize the proteins in the leather and prevent decay. There are different methods of tanning, including vegetable tanning, chrome tanning, and synthetic tanning.

4. Dyeing: After tanning, the leather may be dyed to give it color. Different dyes and pigments can be used to achieve a variety of colors.

5. Conditioning: The leather is then softened and conditioned using oils, waxes, or other treatments to enhance its appearance and feel.

6. Finishing: Finally, the leather may undergo various finishing processes, such as buffing, embossing, or waterproofing, to further enhance its quality and appearance.

Where do Leather Tanneries get their hides?

Leather tanneries get over 99% of their hides and skins as a direct by-product of the global meat and dairy
industries. Livestock is raised for meat and milk production—not for its skin. If tanneries did not buy these hides, tens of millions of tons of animal skins would otherwise be dumped into landfills or incinerated as waste every year.

How long does leather stay in a tannery?

The duration of time a hide stays in a tannery can vary depending on the type of leather being produced and the specific tanning process being used. It can range from a few days to several weeks.

Why do Tanneries use large rotating drums?

Tanneries use large rotating drums to agitate the hides and ensure that chemicals are evenly distributed throughout the hide. This helps to speed up the tanning process and ensure that the leather is properly treated.

Where are most of the world’s leather Tanneries?

Most of the world's leather tanneries are located in countries with a long history of leather production, such as India, China, Italy, and Brazil.
