2. Cellulose nanofibrils
2.1 Mechanical breakdown of cellulose
By subjecting plant cell walls to intense mechanical shear, the original fiber structure is lost, and microfibrils or bundles of microfibrils with diameters of the order of 10 to 100 nm can be extracted. Lengths can reach the micron scale. Initial work dates back to 1983

...Statistical and economic data
It is envisaged that the time-to-market for nanocellulose will be similar to that for plastics.
This curve predicts that the estimated size of the global nanocellulose market will be reached around 2045. Commercial sustainability criteria and global environmental concerns could accelerate production beyond this conservative estimate.
