177. Dye Another Day (REPLAY): The New Way to Color Textiles with Colorifix's Orr Yarkoni

In this replay episode of Grow Everything, Karl and Erum catch up after recent travel, reflect on a standout mainstream biotech article about biology reshaping the global chemical industry, and discuss why “tissue-on-a-chip” experiments in space matter for long-duration missions. They then kick off a deeper dive into bio-based dyes by revisiting their interview with Orr Yarkoni, co-founder and CEO of Colorifix, who explains how engineered microbes can both produce and directly deposit pigment onto textiles to dramatically reduce toxic chemistry, water use, and energy demand compared to conventional dyeing. The conversation covers why black and high-performance reds remain the hardest colors to replace, how Colorifix approaches scale-up through distributed on-site fermentation hardware, and what it takes to meet the real-world fastness and safety standards that brands and mills require.Grow Everything brings the bioeconomy to life. Hosts Karl Schmieder and Erum Azeez Khan share stories and interview the leaders and influencers changing the world by growing everything. Biology is the oldest technology. And it can be engineered.
