The Impossibility of Producing Vegan Leather

/in /by

In recent years, the term “vegan leather” has gained significant traction in the fashion and textile industries as an alternative to traditional animal-derived leather. Marketed as a cruelty-free and environmentally friendly option, vegan leather appeals to a growing demographic of consumers seeking ethical and sustainable products.

However, despite its popularity and the advances in material science, the production of vegan leather presents substantial challenges that call into question the viability of the term itself. This essay explores why producing vegan leather is fraught with difficulties, examining the materials used, the environmental implications, and the fundamental issues underlying the production process.

So What is Vegan Leather?

Definitions and Types
Vegan leather is a term used to describe synthetic or alternative materials designed to mimic the appearance and texture of traditional animal leather. The primary goal is to provide an ethical and environmentally friendly option without using animal hides. Vegan leather comes in several forms:

  • Polyurethane (PU) Leather:Made from a polymer coating applied to a base fabric, such as polyester.
  • Polyvinyl Chloride (PVC) Leather:Produced from a plastic coating that gives it a leather-like finish.
  • Bio-based Leathers:Lighter alternative to steel, providing similar protection.
  • Metatarsal Boots:These include materials derived from plant-based sources, such as pineapple leaves (Piñatex), apple peels, or mushrooms (MycoLeather).

Each type of vegan leather has its own production process, benefits, and limitations, but they all face significant challenges that contribute to the argument that vegan leather is essentially impossible to produce sustainably.

The Production Challenges of Vegan Leather

Synthetic Alternatives: PU and PVC
Polyurethane (PU) Leather
PU leather is a popular alternative due to its similarity to genuine leather and its lower cost. However, its production is not without problems:

  • Chemical Composition:PU leather involves the use of chemicals such as diisocyanates, solvents, and plasticizers. These chemicals are not only hazardous to human health but also contribute to environmental pollution during production.
  • Environmental Impact:Despite being marketed as eco-friendly, the manufacturing process of PU leather is resource-intensive. It requires significant amounts of energy and produces greenhouse gases. The production of PU also involves toxic emissions that can affect air and water quality.
  • Durability Issues:PU leather often lacks the durability and breathability of genuine leather, leading to concerns about its long-term sustainability.

Polyvinyl Chloride (PVC) Leather
PVC leather is another common synthetic alternative, but it also poses several challenges:

  • Toxicity:The production of PVC leather involves the use of chlorine and other harmful chemicals, which can result in the release of dioxins and phthalates. These substances are known to be harmful to both human health and the environment.
  • Environmental Concerns: PVC is not biodegradable and can persist in the environment for hundreds of years. Its production also involves high energy consumption and significant CO2 emissions.
  • Limited Recyclability:PVC leather is challenging to recycle due to the complex chemical composition, which further exacerbates its environmental impact.

Bio-based Alternatives: Piñatex, Apple Leather, and MycoLeather
Piñatex (Pineapple Leaf Fiber)
Piñatex is derived from the fibers of pineapple leaves and is often touted as a sustainable option. However, it faces several issues:

  • Resource-Intensive Production:While the raw material is a byproduct of pineapple farming, the production process of Piñatex involves extensive chemical treatments to enhance durability and flexibility. These chemicals can be harmful and negate some of the environmental benefits.
  • Limited Supply:The availability of pineapple leaves may not be sufficient to meet the growing demand for Piñatex, leading to potential supply chain issues and increased environmental pressure.
  • Performance Limitations:Piñatex often falls short in terms of durability and flexibility compared to traditional leather, which may limit its practical

Apple Leather
Apple leather is made from apple pomace, a byproduct of apple juice production. Despite its promising aspects, it has several limitations:

  • Processing Complexity: The production of apple leather involves combining apple fibers with synthetic binders and coatings, which can introduce additional environmental and health concerns.
  • Durability Concerns:Apple leather’s performance can be inconsistent, particularly regarding its longevity and resistance to wear and tear.

MycoLeather (Mushroom Leather)
MycoLeather is produced from fungal mycelium and offers a biodegradable alternative. However, it faces challenges such as:

  • Scalability:Producing MycoLeather on a large scale remains a significant challenge. The cultivation process requires controlled conditions and may not yet be able to meet the demand for large-scale production.
  • Processing Needs:The production process involves specific treatments to ensure durability and aesthetic qualities, which can introduce additional environmental impacts.
  • Cost Issues:The current cost of MycoLeather is relatively high, which may limit its adoption in mainstream markets.

What are the Environmental Implications of Vegan Leather Production?

Resource Use and Energy Consumption
The production of both synthetic and bio-based vegan leathers requires substantial amounts of resources and energy. The extraction of raw materials, the manufacturing process, and the transportation of finished products all contribute to environmental degradation. For example, the production of PU and PVC leather involves significant energy use, contributing to carbon emissions. Similarly, while bio-based materials like Piñatex and MycoLeather utilize renewable resources, their processing can be energy-intensive and involve chemicals that impact the environment.
Waste and End-of-Life Considerations
One of the critical challenges of vegan leather is its end-of-life disposal:

  • Synthetic Vegan Leathers:Materials like PU and PVC are not biodegradable and can persist in landfills for extended periods. Their disposal can lead to environmental pollution, as they release toxins into the soil and water.
  • Bio-based Vegan Leathers:While bio-based options like MycoLeather and Piñatex are designed to be more environmentally friendly, their actual degradation processes depend on specific conditions. If not properly managed, they may still contribute to landfill waste.

Ethical Considerations and Consumer Perceptions

Ethical Implications
While vegan leather is marketed as a cruelty-free alternative, the production processes involved can raise ethical concerns:

  • Chemical Use:The use of hazardous chemicals in synthetic vegan leathers raises questions about the safety of workers involved in production and the impact on surrounding communities.
  • Animal Welfare:Some argue that even though vegan leather avoids the use of animal products, the environmental and ethical issues associated with its production can undermine the broader goals of animal welfare.

Consumer Perceptions and Misconceptions
The term “vegan leather” can be misleading, as it implies a product that is both environmentally friendly and ethical. However, the reality is more complex:

  • Greenwashing:Companies may use the vegan leather label to market their products as sustainable without addressing the underlying environmental issues. This can mislead consumers who are seeking genuinely eco-friendly options.
  • Informed Choices:Educating consumers about the true environmental and ethical implications of vegan leather is crucial for making informed purchasing decisions.

Future Directions and Potential Solutions

Advances in Material Science
To address the challenges associated with vegan leather, advancements in material science are essential:

  • Developing Sustainable Alternatives:Research into new materials that offer both ethical and environmental benefits could lead to more viable vegan leather options. For example, innovations in algae-based materials or fully biodegradable composites may provide more sustainable solutions.
  • Improving Recycling Technologies:Enhancing the recyclability of synthetic vegan leathers could mitigate some of their environmental impacts. Developing closed-loop recycling systems and improving waste management practices are crucial for reducing the overall footprint.

Industry and Consumer Responsibility
Addressing the challenges of vegan leather production requires collaboration between the industry and consumers:

  • Industry Initiatives:Companies should focus on transparent practices, investing in research and development to create genuinely sustainable products. They should also work on improving the environmental impact of their supply chains.
  • Consumer Awareness:Raising awareness about the complexities of vegan leather and encouraging consumers to make informed choices can drive demand for more sustainable and ethical alternatives.

So What Now For Vegan Leather?

The production of vegan leather presents significant challenges that question the feasibility of its claim to be a truly sustainable and ethical alternative to traditional leather. While vegan leather offers some advantages, such as avoiding animal cruelty, it also involves substantial environmental and ethical issues related to the materials used, production processes, and end-of-life disposal. As the demand for ethical and eco-friendly products continues to rise, it is crucial for the industry to address these challenges through innovation, transparency, and improved practices. Only through a concerted effort to develop genuinely sustainable alternatives and educate consumers can the promise of vegan leather be realized in a meaningful way.

Leather a quick understanding : From Start (in the field) to Finish (out of the shoe box)

/in /by

Why is leather used for safety boots?

Leather is a durable and flexible material that is made from the hides or skins of animals such as buffalo, cows, goats, sheep, and pigs. It is often used in the fashion industry to make shoes, bags, belts, jackets, and other accessories. Leather is valued for its toughness, resistance to wear and tear, and aesthetic appeal. With proper care, leather products can last for many years and even improve in appearance with age. It is one of the oldest raw materials known to mankind.

How do you get from an animal hide to a skin?

The process of turning animal hides into footwear involves several steps, including cleaning, tanning, and finishing.

What’s the first process in getting the leather?

The initial process of removing an animal hide to make leather involves several steps. First, the animal is slaughtered and the hide is removed. The hide is then soaked in water to remove any blood, debris or dirt. It is then treated with a chemical solution to remove any remaining flesh and hair. Next, the hide is stretched and dried to prepare it for tanning.

Tanning is the process of treating the hide with chemicals to prevent decay and preserve the leather. Once tanned, the leather can be dyed, cut, and shaped to create various products.

What happens after tanning of the leather?

After tanning, the hides are treated with finishing agents to make them soft and pliable, and then they are cut and sewn into the shape of shoes. Finally, the shoes are finished with details like laces, buckles, and soles before being boxed up and shipped off to our stores.

Why is buffalo leather better than cow leather in safety footwear?

Buffalo leather is stronger than cow leather because buffalo hide has a unique fiber structure that makes the leather more dense and durable. Additionally, buffalo leather tends to have fewer natural defects than cow leather, giving it an overall higher quality. This is why we use it is the main component in our high quality safety boots and safety shoes.

Is foot safety being taking more seriously?

Absolutely! Safety is being taking more seriously across the planet. And so it should be! According to a report by Grand View Research, the global safety footwear market was valued at USD 5.7 billion in 2018 and is expected to reach USD 8.2 billion by 2025! This indicates a steady and growing demand for safety footwear worldwide.

Leather : The Various “Grades” and What You NEED to Know!

/in /by

What Is Genuine Leather?

(What Animal Hides or Skins Are Used?)

Make no mistake (and it’s an eye-opening fact for many to sometimes hear) if you are walking in a pair of genuine leather shoes… those leather uppers once walked around themselves. Leather is an animal skin (or hide), predominantly bovine – from a cow or buffalo in the sense of safety footwear. It is a NATURAL material. The largest suppliers globally of safety footwear leathers are India and China. But they are also available from Brazil. The greatest “Leather City” is found in India (known as the leather capital), which has been producing since the early 19th century where British forces made their base. With the cow being a sacred animal in India, buffalo hides make up the majority of the skins available for purchase and converting. Cow is however available in certain states.

Why Do We Use Leather?

Leather is used because it can be cut and shaped with ease. It is strong, light, very supple but most importantly – it breathes! Despite massive leaps and developments is synthetic materials – predominantly for sports shoes, leather remains very popular due to durability and comfort when wearing for long hours.

Are There Different Grades Of Leather?

An animal hide is very thick, and can be broken down into layers (often colloquially called; grades). A cross section of an animal hide will show you the outer layer which was covered by hair – all the way to the inner flesh layer closest to the inside organs. Between that lies the full grain / top grain and split. All are classified as genuine leather.

What Is Bonded Leather?

But what part of the genuine leather are you getting? And that’s what you need to know. After the split, you end up with bonded leather. Bonded leather is comprised of very little genuine leather; more flakes of leather held together with a form of polyurethane of latex for bond (and can comprise of as little as 10% leather flakes).

Which Is The Best Type Of Leather?

Now obviously the part that held the skin and hair is exceptionally strong – the epidermis layer. This would comprise of the full grain / top grain. This layer has been exposed to everything from the elements (wind, hail and rain) to fly bites, bee stings and barbed wire fencing cuts. It’s the animals protective layer looking after the insides.

What Is Full Grain Leather? and What Is Split Leather?

In order to have leathers one can work with – cut and shape – you need to reduce the thickness of the leather once it’s off the animal. Once removed it will swell to around 4mm/6mm in substance. And this is why it needs to be split into the various layers (grades). When one splits the leather – try picture peeling bark off a tree. The splitting process then feeds the thick leather between two heavy and giant metal rollers which are turning and pulling the skin inwards – which have settings to move the rollers closer together or further apart (depending on thickness required). On entering the rollers at rapid speed, the leather skin is met on the other side by a super sharp blade running the length of the rollers – which divides (or splits) the leather skin into separate layers. Ah! The puzzle pieces are falling into place now. The picture is becoming clearer. The top layer is the full grain. What’s left underneath forms the start of the split. Some skins can be split again. This is often where the split is thinned and the fibres and flakes are removed. Those final pieces are compacted and joined with latex to create bonded leather. This is really the closest one gets to a synthetic material whilst still using the word “leather”.

When Should I Use Spilt Leather?

Splits are still incredibly useful and valuable – and are often corrected, to create a finished surface which still looks similar to a top grain quality leather. These are used predominantly on Econo type styles. Others used in areas on the shoe and boot which will be under less strain or impact, as a more natural suede (tongue, trim or panel).

How Thick Is Safety Footwear Leather?

Leathers can range anywhere from 0.8mm upwards. But for safety footwear uppers we need something more robust and hard wearing. Leathers need to range from entry level 1.6mm/1.8mm up to 2.0/2.2mm for the very top end footwear. Thinner leathers can be used for the comfort collar lining and tongue.

Why Are Different Types Of Leather So Expensive?

And this is where the price variations come into play between econo styles and heavy duty styles. The best hides are reserved for the best styles. As you create a boot with features to withstand harsher work environments, you use stronger (more resistant) leathers. And the Full Grain / Top Grain is the highest quality leather available.

Through the tanning and finishing process, which takes the actual skin on a journey of treatment and colouring we end up with the workable product which is then cut into panels and stitched together to create the wonderful uppers you see on your shoes and boots. The less panels, the more expensive the boots. The more natural looking and feeling of the upper – the higher the grade of the leather. The softer and more flexible, the better the quality. And watch out for those “plumping up” their thin 1.2/1.4mm leather uppers with synthetic EVA type materials. Often easily seen if you look at the raw edges of the stitched panels. Make sure you are getting what you paid for! Breathability is the most important for comfort!

How Do I know If It Is Genuine Leather?

AND… Always look for the LEATHER LOGO, which is an image of an animal skin laying flat on the ground depicting the full hide spread out. No head, no legs, belly and no tail.
