The debate surrounding the sustainability of leather and plastic is complex and multifaceted. On the one hand, leather is a natural product made from animal hides, often sourced as a byproduct of the food industry, reducing waste. It is long-lasting, repairable, and can biodegrade in landfills within 10 to 50 years. However, the tanning process involves chemicals that can be harmful to the environment, and the livestock industry contributes to deforestation and climate change. On the other hand, plastic, or vegan leather, is often made from polyurethane or polyvinyl chloride (PVC), which are types of plastic derived from fossil fuels. While it does not directly harm animals, plastic may not biodegrade and can release toxic chemicals into the environment during production and disposal. Additionally, the synthetic textile manufacturing process contributes to pollution and reckless resource use. Ultimately, both materials have sustainability advantages and disadvantages, and consumers must make informed choices based on their values and research.

What You'll Learn
Vegetable-tanned leather is more sustainable than plastic
The debate around the sustainability of leather and plastic is a complex one, with several factors to consider. Firstly, it is important to distinguish between real leather and faux or vegan leather, which is often made from plastic polymers such as polyvinyl chloride (PVC) or polyurethane (PU). While real leather is derived from animal skins and hides, vegan leather is synthetic and made primarily from oil, a finite fossil fuel.
When comparing vegetable-tanned leather to plastic, there are several reasons to consider vegetable-tanned leather as the more sustainable option. Firstly, vegetable-tanned leather is free from toxic substances, such as azo-dyes, nickel, PCP, and chrome VI, which are often present in plastic-based leathers. The tanning process for vegetable-tanned leather also encourages a recycled closed-loop system, as many tanneries reclaim hides from the food industry to prevent waste. In contrast, plastic-based leathers are derived from non-renewable resources and are challenging to recycle.
Vegetable-tanned leather is a natural product that will biodegrade in a typical landfill within 10 to 50 years, depending on the type of leather. On the other hand, plastic materials can take 500 or more years to break down, and even then, they may not fully biodegrade. During this extended degradation process, plastics can release toxic chemicals into the environment, contributing to pollution and posing a threat to human and ecological health.
Additionally, the production and disposal of plastic can release toxic chlorine-based chemicals, and plastic is one of the most significant sources of dioxin, a harmful pollutant. Vegetable-tanned leather, on the other hand, is often produced in countries with strict sustainability certification schemes, such as Brazil and Italy, which promote good governance in chemical and water usage, social responsibility, and environmental stewardship.
While the use of animal skins in leather production raises ethical concerns, it is important to note that most leather is a byproduct of the meat industry, reducing waste. If these animal hides were not converted into leather, they would likely be burned or sent to landfills, generating higher carbon emissions. Therefore, when considering the sustainability of leather versus plastic, it is essential to weigh the environmental impact of each material, recognizing the complexities and trade-offs involved.

Vegetable-tanned leather does not contain toxic substances
Vegetable-tanned leather is a product of animal origin, generally made from bovine, ovine or caprine hides, which are by-products of the food industry. The tanning process involves treating the hides with natural dyes and vegetable-based oils and waxes to create a soft, supple finish. This process does not use any toxic substances or heavy metals, making it safe for both the artisans and the end-users, even those with sensitive skin.
Vegetable tanning uses tannins, which are natural extracts derived from vegetable sources such as chestnut and quebracho wood, gall nuts, or tara pods. These tannins are safe for humans and the environment, and they give vegetable-tanned leather its distinct look and feel. The absence of toxic substances in the tanning process means that products made with vegetable-tanned leather are often classics that can be passed down as heirlooms for generations.
In contrast, chrome-tanned leather uses chromium, a heavy metal that is toxic to the environment. Chrome-tanned leather is also more prone to cracking, peeling, and splitting over time. Vegetable-tanned leather, on the other hand, is known for its longevity and durability, making it a more sustainable and environmentally friendly option.
The vegetable tanning process is artisanal and complex, taking up to two months to complete. This lengthy process is one of the reasons why leather is more commonly tanned with minerals like chromium, as it is cheaper and faster to produce. However, the popularity of vegetable tanning has led to the emergence of counterfeits, so buyers must be discerning when choosing vegetable-tanned leather products.
While the debate around real leather versus vegan leather is complex, vegetable-tanned leather stands out for its quality, durability, and absence of toxic substances. It is an environmentally friendly option, especially when compared to synthetic leather, which often contains plastic materials that are challenging to dispose of and recycle responsibly.

Real leather is a renewable resource
The debate around the sustainability of real leather versus plastic is complex and multifaceted. While some argue that vegan leather is more sustainable than real leather, others refute this claim, presenting evidence that real leather is a more environmentally friendly option. One key advantage of real leather is that it is a renewable and natural resource.
In contrast, faux or vegan leather is often made from synthetic materials such as polyurethane or polyvinyl chloride (PVC), both of which are types of plastic derived from fossil fuels. These synthetic materials are not renewable sources and pose challenges in terms of sustainability. The production, use, and disposal of PVC, for instance, can release toxic chlorine-based chemicals, contributing to environmental pollution. Additionally, the disposal of synthetic leather can be problematic, as it may end up in landfills and take years to degrade, releasing harmful toxins into the environment.
Real leather, on the other hand, is biodegradable and will naturally break down in a landfill within 10 to 50 years, depending on the type of leather. This natural degradation process helps reduce the environmental impact of leather compared to synthetic alternatives. Furthermore, real leather is long-lasting and repairable, extending its usable lifespan and reducing the need for frequent replacements.
While the use of animal hides in leather production raises ethical concerns, it is important to recognise that real leather can be sourced responsibly and sustainably. Large leather-producing countries like Brazil and Italy have implemented sustainability certification schemes that promote good governance in chemical and water usage, social responsibility, and environmental stewardship. Additionally, vegetable-tanned leather, a traditional Italian artisan method, offers a more sustainable and eco-friendly alternative to chrome-tanned leather, as it does not contain toxic substances and encourages a recycled closed-loop system.
In conclusion, real leather's renewable nature, derived from animal by-products, contributes to its sustainability. While vegan leather may offer ethical advantages by avoiding animal products, its synthetic alternatives often fall short in terms of renewability and environmental impact. As consumers, it is essential to make informed choices, support transparent production processes, and embrace the concept of slow fashion to minimise our ecological footprint.

Vegan leather is made from artificial or plant products
Vegan leather, also known as faux leather, is a more ethical and environmentally friendly alternative to real leather. It is often made from polyurethane, a polymer that can be made-to-order to suit a designer's needs. Vegan leather can also be made from sustainable and innovative materials such as pineapple leaves, apple peels, cork, cactus, coconut, banana plants, and other fruit waste.
Vegan leather made from plant products is gradually becoming the only real eco-friendly alternative to animal leather. It is also preferred to synthetic vegan leather, which is typically made from plastic. Pineapple leather, or Piñatex, is made from natural and polylactic acid fibres, which are biodegradable. However, Piñatex is coated with a petroleum-based resin, which means the material is not yet biodegradable. The company that produces Piñatex, Ananas Anam, is working on a bio-based coating that will hopefully make the product biodegradable in the future.
Another example of a company using plant-based vegan leather is LØCI, which makes sneakers from maize leather. Maize leather is made from corn husk, which is added to recycled textiles and processed into a material that has all the properties of extremely durable leather. LØCI's sneakers are vegan, eco-friendly, durable, water-resistant, easy to clean, and lightweight.
Vegan leather is also more ethical than real leather because it does not contribute to the excessive use of agricultural lands, deforestation, and animal deaths. Real leather relies on livestock, which is the world's largest user of agricultural resources and lands, and one of the main causes of deforestation, biodiversity loss, and climate change. Vegetable tanning, a more sustainable option for producing real leather, is not widely used.
While synthetic vegan leather is not as environmentally friendly as plant-based vegan leather, it is still more sustainable than real leather. Real leather is produced through chemical-heavy processes that are harmful to the environment, workers, and wearers.

Real leather is biodegradable
The debate around the sustainability of real leather versus plastic is a complex one, with various factors to consider. One key consideration is the biodegradability of these materials. Real leather is often touted as a more eco-friendly alternative to plastic due to its natural origins and biodegradability.
Leather is derived from animal hides or skins, which are naturally biodegradable. In fact, if these hides were not converted into leather, they would likely end up in landfills, contributing to environmental risks. However, the tanning process used to treat leather can impact its biodegradability. The tanning process alters the chemistry of leather fibres, making it more challenging for enzymes from bacteria and fungi to break them down. As a result, the biodegradability of leather depends on the specific tanning chemistry employed.
Processed leather can indeed be composted, but the speed of degradation and environmental impact vary based on the tanning methods used. Vegetable tanning, for instance, is considered a more sustainable option, although it is not widely used. Additionally, the end-of-life disposal of leather articles plays a crucial role in their biodegradability. Leather goods can be found in various environments, including landfills, effluent treatment plants, composting units, or even littered in nature, each presenting unique conditions that influence the biodegradation process.
The demand for eco-friendly leather is rising, and the leather industry is responding by driving more sustainability in the leather value chain. Biodegradability is a key aspect of this initiative. While real leather does have the potential to be biodegradable, it is important to recognise that not all leather is created equal in this regard. The tanning process and end-of-life disposal conditions significantly influence the biodegradability of leather goods.
In contrast, plastic, specifically Polyvinyl Chloride (PVC) plastic, can take over 500 years to break down in the same environment. This stark difference in degradation time highlights the importance of materials that can naturally degrade and return to the environment. While both real leather and plastic have their environmental drawbacks, the biodegradability of real leather is a significant factor in favour of its sustainability.
