Bio-Based, Biodegradable, Organic: These Are Not the Same Thing

Three words, used interchangeably by almost everyone, describing three completely different properties. Get this wrong and you can mislead a customer without meaning to. Get it right and you have one of the clearest advantages available in a crowded, vague market.

Bio-based describes origin. A material is bio-based if it's derived wholly or partly from biomass, plants, crops, or other renewable organic sources, rather than fossil fuels. This says nothing about what happens to the material afterward. Bio-based plastics exist that are chemically identical to their petroleum counterparts and behave exactly the same way at the end of their life, meaning not at all. Bio-based nylon and bio-based polyester are both real, commercially available materials, and neither one biodegrades any faster than the version made from crude oil.

Biodegradable describes end-of-life behavior: whether microorganisms can break a material down into natural components, carbon dioxide, water, and biomass, without leaving persistent fragments behind. This is determined entirely by a material's chemical structure, not by where it came from. A handful of fossil-derived materials are biodegradable. Far more bio-based materials are not, because being made from a plant doesn't automatically mean a material still behaves like one once it's polymerized into fiber.

These two properties are independent. A material can be bio-based and not biodegradable. It can be biodegradable and not bio-based. The only way to know which is true of a given garment is to ask about the specific material, not the marketing category it's been filed under.

Organic is neither of the above. It's an agricultural standard, describing how a crop was farmed: without synthetic pesticides, herbicides, or fertilizers, typically verified by third-party certification such as GOTS. Organic cotton is bio-based, because it comes from a plant, and it's biodegradable, because raw cotton fiber breaks down naturally. But the word "organic" itself is only making a claim about the farm it grew on, not about what happens to the finished garment years later.

We source eucalyptus, wool, cotton, hemp, cashmere, silk, corn, and linen because each is bio-based and, in its raw form, biodegradable. We won't pretend every fiber we use is organic, because most of them aren't grown under that certification, and claiming otherwise would collapse the distinction this piece spent several hundred words drawing. Precision here isn't a technicality. It's the only way any of these claims mean anything at all.
