These days, ethical shoppers may often come across products that are made of ‘Vegan Leather’. Now most of us know what a Vegan is… someone who doesn’t eat any animal-based products only plant based products. But most of us have grown up with things made from Leather… the preserved hide (skin) of all sorts of animals. Now, the question is ‘What is Vegan leather?’
Can you have Vegan Leather?
Ever since humans have hunted animals for food they have found ways to try and keep the skin so that they could use it for clothes or make things for them to use. At first, they just used the dried skin but they found out that it was rock-hard and went rotten pretty quickly. So they had to find a way to keep it soft and last
Back as early as 3000BC, the Sumerians were tanning leather in a very lengthy and stinky process (I will spare you the horrid details but it did involve soaking the hide in urine and rubbing it with pigeon poop…ewwwwww!). The final step was to boil up tree bark to release all the tannin – hence the word ‘tanning’ – and then use this murky brew to boil the skin for hours and hours and make…leather. And folks used the leather for all sorts of things: clothes, bags, shoes, ropes, water bottles… even armour and helmets. These days, apart from using all sorts of chemicals instead of tree bark (and skipping the bits with the pee and pigeon poop) the process of making leather has stayed pretty much the same for centuries.
Leather continues to be used all over the world, and high-quality leather is pretty expensive… especially if it is made from the skins of rare or exotic animals like snakes, minks, and even sharks.
So…What is Vegan Leather made of?
During the Second World War, animal hides were hard to get in many parts of the world, so some smart people started looking around for alternatives – something that looked like leather and felt like leather… without the need for killing any animals. The Germans started making all sorts of things out of a form of processed paper pulp that they called Presstoff, and it worked pretty well except it couldn’t get wet or it would fall apart.
Then in the 1960s, the Dupont company in the USA came up with a range of products made with a fabric base bonded with a soft textured finish made from PolyVinylChloride (PVC). These products had all sorts of names and were used all over the world to make a wide variety of products: clothing, bags, seat covers, furnishings, even covering books. Soon made by many different companies, these ‘fake’ leathers were certainly adaptable (they could be made in almost any colour and in an endless array of textures), and they were quite cheap to make….but they were pretty costly in terms of their damage to the environment.
The Future for Vegan Leather
One problem with many of these PVC products was that the toxic chemicals used in their manufacture (often based on oil and petrol) meant the process of making them was the source of a lot of pollution and, at the end of their life, these products couldn’t be recycled and they often wouldn’t decompose. So whilst they may have been saving animals from the harm they were doing harm to the planet! These days most of the Vegan Leathers are made with polyurethane, which is much less toxic
For years people have been experimenting with all sorts of ways to produce ‘leather-like’ products using plant-based products. They have had some success, but they always require strong chemicals to be used in the production process. For many people who are choosing the Vegan lifestyle as a way of protecting the planet and the natural environment, this is a factor that makes them avoid all kinds of leather… animal-based or plant-based. But lately there have been some very interesting developments in bio-science, where people are actually ‘growing leather’.
Can you Really Grow Leather?
A young American company, Modern Meadow (modern.meadow.com) , has commercialized some recent research and now says they can ‘grow’ leather in a lab! They use a strain of yeast that, when it is fed, produces collagen. Now collagen is not just the thing that movie-stars get injected into their lips (and all sorts of other saggy places) but it is basically what natural animal leather is made from.
So using this special yeast they can grow sheets of …errrm…Vegan Leather!. It looks like leather, it is strong like leather, it feels like leather and they say….yep…. it even smells like leather!
Take a look at their info on their website: https://www.cnbc.com/2018/03/09/modern-meadow-and-evonik-are-brewing-leather-in-a-lab.html
So, now and in the future we could be wearing and using all sorts of completely natural, and plant-based, products made from Vegan Leather.
This could be the alternative option for us – consumers who care about the animal welfare and the planet.
