Leather is made up of animal skin and hide; it is biodegradable. Leather is processed through a tanning process that permanently transforms the chemistry of leather fibers, which makes it difficult for the enzymes in leather to break down easily.

A substance that is capable of being decomposed by living organisms or bacteria and avoiding pollution is biodegradable.
Biodegradation is the decomposition of organic matter by bacteria, fungi, and other microorganisms. Biodegradation is a natural process, which differentiates it from composting.
Why natural leather is biodegradable?
Most organic and natural leathers are biodegradable because they are primarily made from collagen cells. A large number of these cells are derived from animal hides and then tanned to limit and decrease the decay process. Thus, it doesn’t mean it won’t decay at any time. If you purposely leave leather to decay, it will ultimately decompose.
Leather is durable, and their products will last a long time. The long-lasting feature is one of the key features of leather. Now, can an item that lasts for a long time be deemed biodegradable? The answer is yes.
The biodegradability of the leather almost depends on the sort and chemistry of the tanning process.
Is artificial leather biodegradable?
The biodegradability of vegan leather depends on the making process and the raw materials used. Unluckily, most vegan leather is made from plastic or PU, both of which are nonbiodegradable and remain in the environment for many years. Some plant-based options may also come onto the eco-friendly market. One of the most common forms of plant-based leather is made up of mycelium cells. And the fabric made from mushrooms is like leather in its texture.
Why does leather not decompose?
The hide is packed in salt to keep it from spoiling. So the salt reduces the moisture, which prevents decomposition.
Is leather a pollutant?
The leather tanning process uses animal waste, it also uses numerous chemicals to turn raw material into a finished item. Leather industries use resources and emit pollutants that are harmful and dangerous to the environment.
What makes leather biodegradable?
Although general leather is biodegradable, it takes a very long time to decompose, almost 25 to 50 years. Natural leather will decompose into powder faster if left in wet conditions like buried in the soil. Decomposition is also dependent on environmental factors like oxygen levels, UV rays, and the microbial environment.
If leather is well-tanned and kept in conditions that do not allow it to rot, it may last a long time. Natural leather items that are so old have been found by archaeologists.
With some leather products surviving, there is also evidence that natural leather has decomposed, leaving behind rusted metal accessories.
Now, most natural leather is chemically tanned, which makes it last longer and also prolongs its biodegradability.
Biodegradability and leather production
Chrome-tanned leather is made by a chemical method with the use of highly toxic materials that can predispose workers to the leather industry. Its tanning process has been criticized for the chemicals, it uses like formaldehyde, coal-tar derivatives, and water pollutants.
Water waste from leather tanneries, if not processed properly, can find its way to the general public and cause disease. Environmentalists are more concerned about synthetic leather than natural leather products. For the production of artificial leather, PVCs used emit chlorine gas and dioxins during the burst and incineration cycles are important for production.
The process for manufacturing artificial leather depends on the petroleum industry; petroleum materials can find their way into the soil as the product biodegrades slowly.
Natural leather is not clear because it also requires adhesive and is mostly plastic-based and is made using fossil fuels.
Polyurethane is also common and can be an alternative to some extent, although it is not a decomposable substance.
Biodegradable leather or vegan leather.
01. Apple Leather
Apples are also being looked for leather. Although we are used to fruit-based materials such as pineapple peels, banana peels, and orange peels, the use of apples for leather is breathtaking. It is quite exciting that biodegradable and environmentally friendly improvements are being developed for the world’s gems.
They can be utilized to create sustainable leather products, including wallets, bags, and wristlets.
02. Lab-Grown Leather
Lab-grown leather and cell culture meat development as an option for real leather and the meat industry to prevent the killing of animals. Another objective is to have leather biodegradable, eco-friendly substances. A New Jersey-based lab, Modern Meadow, is a company that explores the sheet of collagen protein growth that makes the basis of leather material. The company is working hard to bring its bio-fabricated substance to market.
03. Pineapple Leather, Pinatex
Pinatex, a new organic form of artificial leather created from pineapple leaves is earning popularity in the leather and fashion industries. It weighs about a quarter of what natural leather weighs, with its glamorous textures and pigments. It is durable, soft, pliable, and very easy to care for.
It is created without the requirement for additional pesticides, water, or fertilizer. The leaves are produced as a byproduct of a pineapple farm. Shoes, bags, and other things on the market today were created from pineapple leaves, and they are eco-friendly and biodegradable.
Muskin leather comes from mushrooms; it is essentially a mushroom that has grown into the form of leather. The muskin grows rapidly. You can get an inch in a week, 2 by 3 parts in a month, and a full size in over 2 months.
To make it, the required size and shape of mushrooms are taken from mushroom caps, which are then tanned using all-natural, chemical-free, non-toxic substances.
Because of its chemical-free nature, it is outstanding for products that have direct contact with the skin, such as wristlets, watch straps, hats, and others.
It is so great for ending bacterial growth and has a strong absorption capacity. Some of the qualities of this leather are that it is very breathable, soft, water-repellent, and biodegradable.
