What Is MIRUM? The Most Sustainable Vegan Leather You've Never Heard Of

Meet MIRUM: The Future of Sustainable Fashion

If you've been following the world of sustainable fashion, you've probably heard of cactus leather and apple leather. But there's a newer, arguably more revolutionary material that deserves your attention: MIRUM®.

Developed by Natural Fiber Welding (NFW), MIRUM is a 100% plant-based leather alternative that contains absolutely zero plastic — making it one of the most genuinely sustainable materials available in fashion today.

What Is MIRUM Made From?

MIRUM is made entirely from natural, plant-derived ingredients including:

Natural rubber — sourced from rubber trees
Plant oils — including coconut and other vegetable-based oils
Natural pigments — derived from plants and minerals
Natural fibres — such as cork, rice hulls, and other agricultural byproducts

The result is a material that looks and feels remarkably like premium leather — but is made entirely from the natural world, with no petroleum-based plastics in the formula.

Why Is MIRUM Different from Other Vegan Leathers?

Most vegan leathers — including many marketed as "sustainable" — contain polyurethane (PU) or polyvinyl chloride (PVC), both of which are plastic-based. While these materials avoid animal cruelty, they still contribute to plastic pollution and are not biodegradable.

MIRUM is different in three critical ways:

1. Zero Plastic

MIRUM contains no plastic whatsoever. Every component is plant-derived, making it one of the only truly plastic-free leather alternatives on the market.

2. Fully Biodegradable

Because MIRUM is made entirely from natural materials, it can biodegrade at the end of its life — returning to the earth rather than sitting in landfill for centuries.

3. Carbon Negative Potential

The natural ingredients used in MIRUM — particularly rubber and plant fibres — sequester carbon during their growth. This means MIRUM has the potential to be carbon negative across its lifecycle, a claim very few materials in fashion can make.

What Does MIRUM Feel Like?

One of the most impressive things about MIRUM is its tactile quality. It has a rich, supple feel that closely mimics premium leather — with a slight natural texture that gives it character and depth. It's soft to the touch, holds its structure well, and develops a beautiful patina with use.

For those who love the feel of traditional leather but want a genuinely ethical alternative, MIRUM is the closest thing available.

How Is MIRUM Used at Alessia Jade?

At Alessia Jade, we use MIRUM in select styles where we want to offer our customers the most advanced sustainable option available. Bags made with MIRUM represent the pinnacle of our commitment to ethical, planet-positive fashion — beautiful on the outside, responsible at every level.

Is MIRUM Durable?

Yes. MIRUM is designed to perform as well as traditional leather in terms of durability, flexibility, and resistance to everyday wear. It holds up to regular use, maintains its appearance over time, and — with proper care — will last for years.
