074 — The Dye Beneath (The Compost Problem 1/3)
from You're A Natural Hosted by You're A Natural
A GOTS-certified organic cotton towel carries a covalent dye-cellulose bond engineered in the 1950s to survive hundreds of washes. When you compost it, the cotton biodegrades — but the dye chemistry survives the soil. What does your garden inherit? In this episode, we debate: Is a coloured organic cotton towel genuinely compostable, or does the reactive dye that holds the colour through the wash also survive the compost — meaning the certification scope stops short of the claim the consumer reads into the label? We unpack 5 concepts you will need before reading the article: The Certification Scope Gap, Reactive Dye Chemistry and the Covalent Bond, The Inheritance Adduct, Triazine Ring Homology and Selected Microbiology, and The Effluent-versus-End-of-Life Distinction. This is Part 1 of 3 in The Compost Problem series. This episode takes the chemistry — the bond, the dye, and what the soil inherits. Parts 2 and 3 cover the regulatory architecture and the cross-category pattern.
