Nature's technology.
Self organising. Self assembling. Self regenerative.
This is lignin, a complex amorphous cross-linked polyphenolic biopolymer macromolecule.
Meet cellulose, a biodegradeable unbranched organic crystalline polymer consisting of some 7,000–15,000 base units.
Together with xylan and other hemicelluloses, these molecules form the most abundant organic polymer biocomposite material on Earth: the plant cell wall.
