About us
At Renasens, we’re a small team building something ambitious: a textile recycling technology that will change the world. We have developed a waterless process using minimal energy and chemicals with a neutral impact on fiber quality. This allows us to recycle the most challenging textile waste: blended post-consumer polycotton in any colour, with any additives, composition, or quality, utilizing what is currently the most common yet unwanted fraction of textile waste.

Proven experience (3+ years preferred) in supercritical CO2 technologies, particularly in applications related to polymers and textiles. Someone that is excited to learn fast and change things.
Responsibilities
Development of the textile treatment process using sub-critical or supercritical fluids.
Participating in the implementation of a pilot-scale plant.
Characterization of textiles and textile fibers.
