For full transparency, lyocell is the technical name for our eucalyptus fabric, and because eucalyptus doesn't grow in the ground as a fiber like cotton, the US government classifies it as a "man-made" material. There's been a lot of back and forth with the FTC about this (they claim that it has to literally grow in the ground as a fiber to be labeled "natural"), but we just remind ourselves that all words are made up and not to get too upset about labeling.
Lyocell is a new "third generation" of cellulosic rayon, with viscose as the first and modal as the second (those are more well-known cellulosic fabrics, so if you know them, we're similar but with a much more sustainable production process).
Our sheets are made out of 100% eucalyptus wood, which is turned into a pulp via a closed-loop lyocell process before that pulp is turned into yarn (pictured below). The best part about our Eucalyptus Lyocell is that nearly 100% of the solvents from each batch are reused in the next, so there's almost zero waste (in contrast with the earlier generations of rayon, like viscose).
Additionally, our manufacturer is signed up with Zero Discharge of Hazardous Chemicals (ZDHC), which helps to improve their already leading sustainability standards.
