Tagua: Ecuador's Biomaterial for Sustainable Fashion

I have argued for years that Ecuador's true wealth is not beneath the ground. It is on the surface: in its forests, its rivers, its soils, and the extraordinary diversity of life that makes our country one of the most biodiverse places on the planet.

This week, the Embassy of Ecuador had the opportunity to bring that argument into a very specific room: Habit Impact Day 2026, Stockholm's gathering of designers, textile innovators, sustainability professionals and fashion brands working to reimagine an industry that remains one of the world's most resource-intensive. We came with a material. A small, hard seed. One that carries a larger story.

We came with tagua.

Known internationally as vegetable ivory, tagua is the seed of Phytelephas aequatorialis — the Ecuadorian ivory palm, native to Ecuador's coastal and Amazon rainforests. When dried and matured, the hard white endosperm of the seed becomes dense, durable and polishable, with a fine marbled grain that closely resembles ivory. It is an Ecuadorian material in the fullest sense — grown here, harvested here, and part of the country's economy and culture for generations.

Before synthetic plastics transformed global manufacturing after World War II, tagua was a dominant material for buttons — exported in the millions to factories across Europe and the United States. Then plastic arrived. Cheaper, faster, scalable. Tagua retreated.

Today, the conversation is reversing and for good reason.

The fashion industry has made significant progress on fibres and fabrics. Organic cotton, recycled polyester, alternative leathers, bio-based textiles, these are real advances. But the components of a garment are rarely part of the same conversation. Buttons, clasps, accessories, finishing details (the small pieces that hold a garment together) are still predominantly made from fossil-based plastic.

That is the gap tagua can fill.

A single button is not a dramatic object. But multiply it across millions of garments, across dozens of seasons, across a global supply chain that discards rather than repairs, and the numbers become significant. Replacing plastic buttons with a natural, biodegradable, traceable biomaterial is not a marginal decision. It is a design choice with measurable consequences.

I want to be precise about something, because the sustainability conversation sometimes moves faster than the evidence.

Tagua is not automatically sustainable simply because it comes from nature. What makes it a genuinely regenerative input is the chain behind it: responsible collection that does not deplete palm populations; fair economic participation for the rural communities who harvest the seeds; ecological management that creates incentives to preserve the forested landscapes where these palms grow; and full traceability from forest to finished product.

When that chain is built with rigour (and it can be ) tagua becomes something more than a material. It becomes a bridge. Between biodiversity and industry. Between local communities and global markets. Between Ecuador's natural capital and the needs of a fashion sector searching for lower-impact alternatives.

This is precisely what I mean when I argue that Ecuador's biodiversity is not a heritage to be protected in isolation, but a productive asset to be managed intelligently.

Habit Impact Day put us in the right room. Sweden has built one of the world's most credible ecosystems around circular economy, sustainable design and responsible sourcing. Ecuadorian producers have the material, the knowledge, and, with the right partnerships, the capacity to build supply chains that meet the standards European brands increasingly require.

The opportunity is concrete: Ecuadorian tawa harvesters. Swedish designers. Fashion brands that need certified, traceable, low-impact components. A shared interest in demonstrating that responsible trade between a biodiversity-rich country and an innovation-driven economy can generate value for both.

I left Stockholm's sustainable fashion community with the same conviction I carry from my work stopping plastic in Ecuador's rivers: the solutions already exist. What they need are the bridges to reach the markets that want them.

Tagua is one of those solutions. And building those bridges is exactly why I am here.
