193. The Full Color Spectrum: Nick Milne Ferments One Pathway for Every Color at Octarine Bio
from Grow Everything Biotech Podcast · host Messaginglab
Nick Milne, founder of Octarine Bio, joins Grow Everything to unpack how biology can reshape the future of color. In this episode, Nick explains why synthetic dyes have dominated textiles for more than a century, why sustainability alone is not enough to drive adoption, and how Octarine is building bio based pigments that can compete on performance, price, and scale. The conversation explores the environmental and human health problems tied to petrochemical dyes, especially azo dyes used in polyester, while showing how precision fermentation can create high strength pigments that work as drop in replacements for existing dye house workflows. Nick also shares how Octarine thinks about scale up, regulatory pressure in Europe, investor expectations, product development, and the practical realities of bringing biotech products into old and highly cost sensitive industries.Grow Everything brings the bioeconomy to life. Hosts Karl Schmieder and Erum Azeez Khan share stories and speak with the leaders and innovators using biology to change the world. Biology is the world’s oldest technology, and it can be engineered.
