Blue Cast: Sortile Co-founder Constanza Gomez on Solving Textile Sorting

Sortile is on a mission to simplify this process through technology. For the second episode of Blue Cast’s four-part Circularity Solutionist series in partnership with the Fashion Impact Fund, Lenzing’s Tricia Carey spoke with Constanza Gomez, Sortile’s co-founder and CEO.
