Fabric

SUBSTANCE ·

2026/02/18

Fabrics and fashion are deeply tied to sustainability – not least because the scale of production and consumption means huge volumes end up as waste or pollution. This episode of SUBSTANCE asks what it would take to “close the loop” and move fabrics toward a circular economy. Host Joe Hanson draws on perspectives from both the Hong Kong–based nonprofit Redress and BASF in his exploration of why circularity is a useful way to turn intent into action; from designing for durability, repair and
