What is T2T?

In an industry used to reinventing trends every season, one problem remains: what happens to clothing after it is no longer used. Every year, millions of tons of textiles are discarded, yet according to the Ellen MacArthur Foundation, less than 1% of all clothing produced globally is recycled into new clothing.

This contrasts sharply with the industry’s growing sustainability discourse, where terms like “eco-friendly” and “conscious” have become almost omnipresent. Behind campaigns and labels, sustainability is still often treated as a marketing argument, when in reality, it begins much earlier: in the way fabrics are designed and produced.

And it is precisely at the source that some companies are now trying to rewrite the cycle. Riopele, in collaboration with different partners, has been exploring one of the most complex challenges of textile circularity: how to transform post-consumer waste into a viable raw material, with enough quality and scale to return to the value chain.

This concept is known as T2T (Textiles-to-Textiles) and proposes something more ambitious than recycling: closing the loop.

For decades, textile recycling followed a limited logic. Garments were produced with little consideration for their end of life and, once discarded, materials were reused whenever possible — often with a significant loss of quality. The result is a system that partially reduces waste, but does not eliminate it, while remaining dependent on virgin resources.

Circularity, as it is understood today, proposes a break from this model. Products are designed from the beginning to be recycled, dismantled, and reintegrated. The ambition is simple in theory, but demanding in practice: transforming waste into new equivalent products, without significant loss of value.

However, when it comes to textiles, theory quickly meets complexity. Unlike more uniform materials such as glass or plastic, a fabric is rarely made from a single material. It may combine multiple fibers — such as polyester, viscose, or elastane — include different dyes, and contain chemical finishes that alter its performance.

This diversity, which is precisely what allows innovation and functionality, becomes an obstacle when the time comes to recycle.

Making T2T a viable industrial-scale solution means overcoming each of these barriers simultaneously.

This is where industrial geographies such as Portugal can gain relevance. The proximity between production, development, and research has made it possible to accelerate solutions and test them in real contexts. Companies like Riopele have been investing in innovation and building partnerships with technological centers, positioning themselves within an ecosystem that seeks not only to adapt, but to lead this transition.

T2T, however, is unlikely to be a standalone solution. It is part of a broader system where design for recycling, material traceability, and digitalization — including the so-called digital product passports — become essential pieces.

At a time when the fashion industry is being called to answer for its impact, the question is no longer whether change will happen, but how quickly it can scale. And perhaps more importantly, whether it can do so before the problem of waste exceeds our ability to reinvent it.
