Handbags

Luxury brands are known to use rare and expensive materials to justify their prices. One of these sought after materials is alligator leather. One particular brand that is synonymous with high-end luxury would be Hermès. One of their most iconic and expensive bags ever made would be their Alligator Birkin that was priced at a staggering US$379,261 at auction.^[5] Luxury brands prefer the highest grade under belly section of the alligator, as they usually need a large piece of the hide. Lower grade alligator leather usually has scar tissue that would decrease the value of the product.

Boots or shoes

Alligator leather shoes and boots are a common sight in high-end retail stores. It also is common for the American Midwest/Cowboy market to invest in alligator Leather boots or shoes due to its durability. While high-grade leather can create exceptional quality, low-grade leather can also be pieced together to create a great product.

Clothing

Leather use for clothing dates back to 1200BC when ancient Greeks^[6] used it as a material as it was durable and helped tackle different climates. While leather is still used as a material for winter clothing, due to its rarity and exclusivity, alligator leather has become a luxury. High-end expensive brands use alligator hide for clothing items, most popular being jackets and winter wear.

Extraction of skin

Depending on what the final product will be, tanneries dissect and process that portion of the alligator. For a softer and more malleable product, tanners choose to use the underbelly and perform a "belly cut".^[7] Usually younger farm raised alligators are chosen for this process as the skin is not as tough as an adult alligator. Underbelly hide is usually used for luxury products and so therefore farm raised alligators will not have scars or marks as wild alligators may have. This is due to the fact it is not raised in the wild and therefore do not encounter situations that would cause scars or damage to the skin.

The "hornback cut" however is used more for the raised scaly appearance that products such as belt or boot makers desire. This is the top portion of the alligator. Older wild alligators are used for this process of leather.^[7]

Scraping

The raw hide is then scraped using usually a dull tool so that it does not penetrate or cut the skin. This removes the remaining flesh and fat on the hide. Once this is done the inner portion of the skin will look white.^[8] This however does not fully remove all flesh and fat. Once this is done, wash the skin to remove any blood or flesh residue that is attached to the skin. Leave to dry.^[8]

Dry salting

Once dry, a layer of salt is applied to all parts of the skin to completely dry it out. Drying out the skin will slow the process of decomposition.^[8] This process is usually done twice or three times.

Brining or pickling

Once the salting process is done, the hide is ready for brining. Brining is the chemical process that further enhances the curing process of the alligator. This is to remove any bacteria or elements that could attract bacteria, as that is what causes decomposition. To brine the hide, usually a mixture of bleach, borax and salt is added to water in a plastic drum. The alligator is then soaked in the solution for about 48 hours ^[9] to completely remove any non-tannable proteins.

Neutralizing

For optimum tanning acidity levels (pH level 4 or 5), sodium bicarbonate is added to the pickle solution. Throughout the pickling stage, the water must be a room temperature level.^[9] The hide is then returned to the plastic drum for another 20–30 minutes.^[9]

Degreasing

Degreasing is the process of removing any left over fat from the hide so that there is no chance of oil or fat stains. This can be done with a degreasing product or heavy duty washing liquid. The hide is placed in another plastic drum with the product or washing liquid and warm water.^[10]

Vegetable tanning

Vegetable tanning uses the natural tannins that are found in plants, tree bark and other natural sources. This process produces brown leather that is soft and malleable. Although it is great for products such as bookbinding or early plate armour due to its softness, when in contact with water, the leather tends to shrink in size, as it is unstable.^[11] This is one of the most environmentally friendly ways to tan leather as no additional acids or chemicals are used.^[12]

Environmental impact

The environmental impact of leather, especially at the tanning process, has a mass negative effect. The waste product of tanning can be broken down into two categories.

Health complications

The tanning industry not only causes detrimental environmental impact, it also creates many health complications for workers in countries without effective safety regulations and protection standards. Some of these countries are China, India and Bangladesh.^[11] The toxic exposure to the chemicals in tanneries causes skin and respiratory disease amongst workers due to the lack of safety equipment and training.^[19]

Tanneries that use chromium increase the chances of workers getting respiratory illnesses and can sometimes lead to lung, nasal or sinus cancer.^[11]

The raw hides are also a breeding ground for anthrax left untreated this can be a potentially deadly disease.^[20] Chromium tanning also can severely destroy skin amongst workers. Due to unprotected handling, when the skin absorbs chromium it can leave the skin dry and cracked. The acidity in the tanning and liming stages can cause erosions in the skin, which is irreversible. According to a report in 2001 estimate, around 90% of workers die before the age of 50 due to health complications in Hazaribagh, Bangladesh; a city well known for its tanning industry which has low health and safety standards. This being one city compared to the many around the world^[21]
