Is leather biodegradable?

This blog post will answer the question, “Is leather biodegradable” and cover topics like the biodegradability of leather and frequently asked questions related to the topic.

Is leather biodegradable?

Yes, leather is biodegradable.

Are leather products biodegradable or not?

Yes, leather products are biodegradable.

Since collagen cells are mostly used to manufacture natural leather, the answer is yes. The majority of these cells come from animal skins and are afterward tanned to slow down and minimize the decaying process. 

That doesn’t imply it won’t decay at some point, however. Leather will ultimately disintegrate if left to decay on purpose.

Of course, not all leathers fall within this category. However, this category includes virtually entirely organic and natural leather and leather goods.

Leather is quite robust. Nearly all items manufactured of high-quality leather will last you the longest. The greatest thing is that they become better as they mature. Thus, one of the main characteristics of leather is its durability.

Can a product that lasts the longest be considered biodegradable at this point? 

Thankfully, the answer is yes. Several times, only biodegradable ingredients may be used to create leather. Leather that is natural and organic may very probably be composted and biodegradable.

The kind and chemistry of tanning used on the leather, however, nearly totally determines how biodegradable it is. Not all leathers belong under this category, despite the possibility that certain leathers are biodegradable.

How Much Time Does Leather Take to Biodegrade?

The biodegradation of leather takes time. In terms of sustainability, it is quite ineffective. In a suitable climate, regular cured leather takes 40 to 50 years to degrade. 

For leather to totally disintegrate, there are a few highly precise environmental requirements.

Theoretically, you could expose leather to direct sunshine to hasten its deterioration, but it would still take at least 30 years. To decompose into various compounds, the majority of tanned leather also requires a certain kind of bacterial presence.

Leather’s lifespan may be greatly increased by storing it in a dry place that doesn’t decay. If properly preserved, certain leather items may endure for thousands of years. When using imitation or synthetic leather, the issue is significantly worse.

In the past, individuals have tried to make leather-based items last longer. They have also seen incredible success, which is quite unfortunate for the world. Some firms have just lately begun exploring more environmentally friendly options.

On that front, there have been a few modest achievements. More durable and biodegradable leather is produced by certain companies. However, this method is quite expensive, therefore few manufacturers use it.

Why Does Leather Decompose More Slowly?

As more and more leather artifacts are discovered, it is becoming obvious that even while leather may deteriorate, it will still probably leave behind a number of rusted parts.

The majority of older leather survived because it was kept under certain guidelines, ideally in a dry area with a relative humidity of 50% and a very low oxygen content.

When calculating the durability of leather, we must also take into account still another important component. The majority of leather was tanned throughout the 19th century largely using a method called vegetable tanning. 

The lifetime of these leather varieties is much greater than that of their current equivalents thanks to one of the strongest tanning techniques.

Leather is now produced more responsibly in response to global warming and other environmental harms. It is biodegradable and robust as a result. 

It is advisable to verify with the producer about the leather’s biodegradability rating before making a purchase, albeit this only applies to certain kinds of leather.

Is synthetic leather biodegradable as well?

Man-made leather, which is sometimes sold under the names pleather, leatherette, synthetic, or vegan leather, is biodegradable like genuine leather but degrades considerably more slowly since it is constructed of polyvinyl chloride, cork, or polyurethane (PU).

Despite the fact that both natural and synthetic leather may be said to dissolve, it will take synthetic leather more than 50 years to biodegrade, decay, and return to the ground.

Other synthetic materials that are used as leather substitutes but are not UV stabilized could degrade fast.

The majority of products you will discover while shopping for bags, shoes, etc. nowadays are made of synthetic leather. The marketing approach often employed for products made of synthetic leather is one that prioritizes ethics and the environment.

How to dispose of Leather?

Even biodegradable leather disposal has negative environmental effects. Its hands are already stuffed with garbage and nuclear waste.

The worst possible approach to dispose of it would be to attempt to burn it or use it as fuel for a fire. Try composting it; that’s your best option. Even with powerful disintegrating agents, the procedure would presumably take a while.

Unfortunately, the use of synthetic pigments and other enhancing chemicals prevents their breakdown. They impede the leather’s manufacturing process as well.

Additionally, you would have to take the metal pieces out of the leather. Recycling leather is still the best method to get rid of it.

Can Leather Be Recycled?

Yes, leather can be recycled, yes. But unlike glass, it cannot be melted and reshaped. Repurposing, in my opinion, is the appropriate phrase for the procedure. 

Leather is very adaptable and, under the appropriate circumstances, will endure a very long time.

Making new leather goods is a terrific use for leather scraps. However, the leather sector is opposed to its widespread usage. That greatly affects the product’s quality. The quality of products manufactured from recycled waste suffers.

For a leather manufacturer, making it from waste is also more expensive. The whole procedure is very ineffective.

The situation is made worse by the fact that many recycling centers would not even take leather. Because of this, it may be difficult for many individuals to dispose of their leather trash. 

You may possibly identify the establishments that do take leather by doing some investigation.

Can Faux Leather Decompose?

Yes, it can decompose but takes a lot of time. 

Plastic is required for the foundation of the extensively used imitation leather. Phthalate is also necessary for the leather-like qualities of several other synthetic leather varieties. 

These two materials do not biodegrade well at all. Therefore, typical fake leather cannot be composted.

The majority of imitation leather also generates a great deal of hazardous waste during production. The pollutants harm both people and animals.

One of the main basic materials for traditional imitation leather is PVC. Dioxin is a byproduct of PVC production. Dioxin is very poisonous and persists for a very long period in the environment.

The fact that many recycling facilities reject leather items is also due to this synthetic leather. It’s difficult to tell them different from genuine leather. 

That can potentially make the arrangement useless. Faux leather won’t even disintegrate in landfills, so you can’t even dispose of it there.

Some claim that traditional imitation leather is better for the environment than genuine leather. The majority of their arguments center on the idea that it is not animal cruelty.

Marketing of this kind is very deceptive. Synthetic leathers are as bad as natural leather, if not worse.

Biodegradable Leather Replacements

Not all in the leather industry are gloomy. Alternative leather types that are very eco-friendly are constantly being developed and produced. Some of them could be expensive. They are still in the research and development phase, which mostly explains this.

However, a few suitable kinds already exist.

  • Muskin
  • Pinatex
  • AppleSkin

I will now elaborate on these.


Muskin is the alternative leather I like most. Muskin is neither leather nor is it a product of chemical synthesis.

This material is produced by growing mushrooms in leather-like shapes. Phellinus ellipsoids are the fungus that is most often utilized for this.

Huge mushrooms called Phellinus Ellipsoideus are found on the sides of enormous tree trunks. If you traveled in China, you may have even encountered this kind of fungus.

Since muskin leather is completely biodegradable, it is perhaps the best invention since bread.

Muskin is a preferable material for footwear since it has a softer texture than conventional leather. To the touch, it has an almost cork-like softness. These mushrooms are also growing quite quickly. Up to an inch may develop on them each week.


Pinatex may seem like a high-end clothing brand, but it is not. This particular leather is created with pineapple leaves. The leaves of the pineapple plant are highly flexible and rich in fiber. This makes it durable enough to take the place of leather.

A few chemical pigments are needed for the curing process. This is done to increase the completed product’s durability.

Because of this, Pinatex is only 90percent biodegradable. Nevertheless, since it decomposes quickly, it is still superior to animal hide.

Additionally, there is an endless supply of raw materials everywhere in the globe. Once the technology develops further, it may become widely used. However, this leather still needs minor modifications to increase its longevity.


Another soft material with a leathery feel is called AppleSkin. This fruit-based leather is produced using a leftover from the fruit juice business.

The dried apple waste from the food sector is used in the production of this leather. The trash is then ground into a powder and mixed with polyurethane. Cotton and polyester are also applied as a layer to the textile.

Although using polyester and polyurethane as a biodegradable substitute may sound strange, it really has a relatively low long-term carbon impact. 

The cloth can be recycled and doesn’t create any hazardous waste. Compared to typical leather, the whole process is cleaner.

Frequently Asked Questions(FAQs), “Is leather biodegradable?”

Why cannot leather biodegrade?

The intrinsic chemistry of leather fibers is altered throughout the tanning process, which is how leather is handled. The enzymes in leather find it tough to quickly degrade as a result. 

It also alters the leather’s biodegradable component, as one would expect. Though not all leathers are non-biodegradable, this is true.

Is leather biodegradable or nonbiodegradable?


Silver foil, plastic cups, and iron nails cannot decompose, while leather belts may. Between 24 and 50 years are needed for leather to totally deteriorate. 

Due to the chemicals used to tan the leather, it might take a lot longer for the leather to break down.

Does leather break down?

When high-quality leather is properly maintained, it may endure for many years, age gracefully, and develops a patina. Real leather has to be kept and moisturized since it is animal skin; otherwise, it may ultimately split and peel.

Can leather be composted?

Yes, it can be composted.

All compostable materials, including leather, should be devoid of metal. Additionally, the leather may contain oils that are harmful to composting. 

While tanning chemicals, dyes, and pigments may all decompose under certain biological circumstances, they may not be present in the backyard compost pile.

Wool: is it biodegradable?

Wool’s biodegradability is one of its best qualities as a sustainable material. Keratin, the protein found in human hair, is the main component of wool. 

Woolen material may be broken down by microorganisms in soil or water, and as a result, these microorganisms likewise decompose, maintaining a constant biological life cycle.

Are shoes made of leather biodegradable?

Yes, they are.

Leather is a completely biodegradable material by nature. The environmental effects of leather depend on how it is processed to make it acceptable for use in final items like shoes, leather goods, or upholstery.
