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.
