R-Skin by Bolflex: when waste becomes leather

Bolflex, a Portuguese company specialising in rubber soles and a partner of the FAIST consortium, has developed: R-Skin.

The project stems from a simple question: is it possible to transform industrial waste from different sources into a material that can replace leather? The answer, it seems, is yes. But beware: we are not talking about yet another ‘green’ alternative destined to remain confined to laboratories. R-Skin is a sheet material designed to enter the footwear supply chain directly with real industrial requirements.

The heart of the innovation lies in the formulation. Combining waste from different applications poses a significant technical challenge: each type of waste has different characteristics, and the goal is to maximise their use without compromising durability, flexibility and aesthetic appeal. This is where intensive industrial design work comes into play, aimed at optimising every variable in the process.

The tests conducted evaluate the performance of the material on concrete parameters: how resistant it is, how it bends, what it looks like. Because in the world of footwear – let’s not beat around the bush – a sustainable material that does not stand up to market testing remains an academic exercise.
