What if your plant fibres were also the mines of tomorrow?

A fibre field. A green mine. What if they were the same thing?

Imagine a flax field in Normandy, or a hemp plantation in the Berry region. You see a textile raw material, a supply chain, a sustainability commitment. Researchers, however, are beginning to see something else: a mine. Not metaphorically. Literally.

Spring 2026 marks a turning point in phytomining research, the extraction of strategic metals through plants. Within just a few weeks, three major scientific publications removed barriers that had been blocking this technology for years. Measure, extract, deploy at industrial scale: all three challenges are now on track to be solved simultaneously.

For the ITBA community, this convergence is far from anecdotal. It strikes at the heart of what we stand for: the systemic value of plants, well beyond the fibre.

Rare earths: a strategic challenge the textile world knows well

Behind our smartphones, wind turbines, electric vehicles and aerospace equipment hide metals the general public never sees: rare earth elements. Dysprosium, neodymium, terbium... These elements are essential for the high-performance magnets that power electric motors, turbines and embedded systems.

Their current extraction is a silent environmental disaster. Each tonne of rare earths extracted generates on average 2,000 tonnes of toxic waste and nearly 1,000 tonnes of acidic wastewater. China controls around 70% of global production and over 85% of refining, a strategic dependency that deeply concerns Europe and its industrial players.

This context echoes, in many ways, what the textile sector experienced with conventional cotton: geographic dominance, massive environmental impacts, supply chain vulnerabilities. And as with textiles, nature may well offer a way out.

Phytomining: letting plants do the work

Certain plant species possess a remarkable ability: they absorb metals present in soils, even at very low concentrations, and accumulate them in their tissues. These are called hyperaccumulators. Until now, two obstacles had blocked industrialisation: precise measurement of metal content required destroying the plant, and post-harvest extraction processes were inefficient.

Both barriers have now been lifted.

Researchers at North Carolina State University developed a fluorescence-based detection technique that measures dysprosium concentration in plant tissues in real time, without cutting or damaging the plant. By exploiting a unique property of this metal (it emits light longer than other plant signals), they can now track accumulation throughout growth and optimise the harvest window.

Meanwhile, a study published in Communications Materials solved the extraction problem: by applying 1,000°C for 20 seconds followed by a mild acid treatment, researchers achieve up to 97% metal recovery, compared to the 70–90% ceiling of conventional mining.

Finally, a publication in Nature Communications Earth & Environment identified an ideal candidate for large-scale deployment: the fern Dicranopteris linearis, capable of naturally accumulating rare earths without intensive cultivation.

What this means for plant-based supply chains

The connection to the ITBA universe is direct and profound. The plants we cultivate for fibre, flax, hemp, nettle, kenaf, bamboo, belong to related botanical families, or share soils and ecosystems with the hyperaccumulating species identified by researchers. Some are themselves being studied for their own accumulation properties.

What is emerging is a paradigm shift in how we value plant biomass. A single crop could tomorrow fulfil three functions simultaneously:

▸ Produce a low-impact textile fibre,

▸ Remediate contaminated soils (phytoremediation),

▸ Generate strategic metals recoverable at end of cycle.

This is precisely the circular economy logic championed by FiberForever™, taken to its ultimate stage: zero waste, zero loss, maximum value extracted from every kilogram of cultivated biomass.

Concrete implications for our members

For Alliance members, whether in luxury, sport, cosmetics, aerospace or mass retail, this development deserves immediate strategic attention.

The plant-based supply chains you are building today are no longer limited to textiles. They represent a versatile strategic asset, potentially contributing to the supply of critical materials for electronics and mobility.

The territories you are cultivating with your short supply chains could become phytomining zones, transforming degraded soils or industrial brownfields into renewable resources.

The certifications you are building with FiberForever™ already position you within a framework of traceability and measurable impact, exactly the criteria that will apply to responsible phytomining supply chains.

A conviction that guides our Alliance

At ITBA, we have always maintained that plants are at the centre of the industrial transition, not at its periphery. Phytomining only confirms what the most forward-thinking members of our Alliance have long sensed: sustainable plant-based supply chains are not a compliance cost. They are strategic infrastructure for the world of tomorrow.

We will closely follow developments in this technology and support our members in understanding its implications for their business models. The first industrial applications may be closer than expected.
