What vegan leather is made of
Short answer
Vegan leather is a marketing term, not a material. It covers at least nine things with nothing in common except the absence of hide: polyurethane film, PVC, pineapple leaf fiber, cactus, cork, apple waste, and cultivated fungus. Most of what sells under the name is polyurethane on a fabric backing.
Two names that still contain hide
- Bicast leather — a polyurethane film laid over real split hide. The surface is synthetic and the material underneath is an animal.
- Bonded leather — leather scraps and dust bound together with polyurethane, then embossed. Typically sold on furniture and book covers.
Both sit next to genuine synthetics on a shelf and both read as plastic to a shopper. If a product says bicast or bonded, it is leather.
Polymer coatings
A plastic layer bonded to a fabric backing. The established options, and the overwhelming majority of what is sold as vegan leather.
PU Leather
PU leather is vegan. Polyurethane is coated onto a polyester or cotton backing, so the sheet holds only plastic and fabric. Two labels break that rule: bicast leather is PU film over real split hide, and bonded leather binds leather scraps with PU.
PVC Leather / Vinyl
PVC leather is vegan. Polyvinyl chloride, made from chlorine and ethylene, is layered over a fabric backing with no animal component anywhere in it. Its chlorine chemistry throws off dioxins and its plasticizers can leach, which is why most sustainable-fashion advice ranks it below PU.
Ultrasuede
Ultrasuede is vegan. Miyoshi Okamoto developed it at Toray Industries in 1970 from polyester microfiber bound with polyurethane, a non-woven sheet with no hide in it. Alcantara, its closest generic equivalent, lines Ferrari and Porsche interiors.
Built from plant waste
Agricultural byproduct pressed into a sheet, usually with a polymer binder holding it together. The bio-based share varies and is rarely published.
Piñatex
Piñatex is vegan. Carmen Hijosa built it from pineapple leaves left behind after harvest in the Philippines; the fibers are felted with corn-based PLA and sealed with a resin coating. That coating is petroleum-based, which is why the sheet only partly biodegrades.
Cactus Leather (Desserto)
Cactus leather is vegan. Mature nopal leaves (Opuntia ficus-indica) are cut without killing the plant, then combined with a polyurethane binder on a cotton or polyester backing. Desserto launched it in Mexico in 2019; the cactus fraction biodegrades and the binder does not.
Apple Leather
Apple leather is vegan. Pomace left from juice and cider pressing in South Tyrol is dried, powdered, and bound with polyurethane on a textile backing. Roughly half the coating is plastic, so it does not fully biodegrade.
Mango Leather
Mango leather is vegan. Skins and seeds discarded during juice and pulp production are processed and bound with polyurethane, so the sheet is part fruit and part plastic. India, which grows about 40% of the world's mangoes, has raw material to spare.
Cork Leather
Cork leather is vegan. Bark is stripped from living cork oaks (Quercus suber) in Portugal, which supplies about half the world's cork, and it regrows over roughly nine years with the tree left standing.
Grown rather than made
Mycelium, the root structure of fungi, cultivated into a mat and finished. The newest category and the smallest by volume.
Mylo
Mylo is vegan. Bolt Threads grows Ganoderma tsugae mycelium on corn waste, then harvests and tans the fungal mat into leather-like sheets. Growth takes days, and Stella McCartney, Adidas, and Lululemon have each run limited pieces in it.
Muskin
Muskin is vegan. The cap of Phellinus ellipsoideus, a fungus that grows wild on dead trees, is processed without chemicals by Grado Zero Espace in Italy, at a scale small enough to keep it expensive.
How much of a plant leather is plant
Nearly every plant-based leather is a sandwich. A bio-based layer sits on top, a polymer binder holds it together, and a textile backing carries the strength. The plant share is the part that gets the name, and it is often the smallest part by weight.
Piñatex is pineapple leaf fiber with a resin finish. Cactus leather is nopal powder in a polyurethane matrix. Apple and mango leathers use fruit processing waste the same way. None of this is hidden, and almost none of it is on the front of the pack.
Cork is the exception worth knowing. Cork leather is bark, harvested by hand on a nine-year cycle without felling the tree. The sheet is usually agglomerated granules on a fabric backing with a polyurethane bond, so it carries a binder like the rest. What sets it apart is the harvest, and a cork oak keeps producing for two centuries.
Common questions
Frequently asked questions
Is vegan leather the same as PU leather?
PU leather is one kind of vegan leather, and the terms get used as if they were the same thing. Vegan leather covers any leather substitute with no animal hide in it, including cactus, pineapple leaf, cork, and mycelium. PU is the specific one made from a polyurethane coating on a fabric backing, and it is the most common by a wide margin.
Is PU leather real leather?
Standard PU leather contains no hide. Two product names break that rule and both are sold openly: bicast leather is a polyurethane film laid over real split hide, and bonded leather binds leather scraps together with polyurethane. Either one is an animal product wearing a synthetic name.
Is TPU leather vegan?
Thermoplastic polyurethane is a synthetic polymer with no animal input, so TPU-coated material is vegan by composition. Brands market it as an upgrade on standard PU because it needs no plasticizers and handles flexing better. The same bicast caveat applies: check that the backing is textile and not split hide.
How much of cactus leather is cactus?
Less than the name suggests. Most plant-based leathers are a bio-based layer bonded with a polymer binder onto a textile backing, so a sheet advertised as cactus leather can be well under half cactus by weight. That does not make it a bad material. It makes the marketing shorthand imprecise, and the brand's technical specification is where the real composition sits.
Is vegan leather better for the environment?
It depends which one and which impact you weigh. Tanning hide is chemically heavy and cattle carry a large land and methane footprint. Polymer leathers come from fossil feedstock and shed microplastics. Cork and mycelium avoid both, and neither is available at the scale PU is. There is no version of this question with a clean answer.
Does vegan leather last as long as hide?
Standard PU generally does not. It delaminates and cracks after a few years of hard use, where good hide keeps going for decades. TPU and the better coated fabrics narrow the gap. If longevity is the concern, buying one well-made synthetic piece and keeping it beats replacing three cheap ones.
