goods, etc. Nanocellulose is now used as a membrane for high quality sound in electro-
acoustic devices. Additionally, nanocellulose is utilized in membrane for combustible
cells (hydrogen), as additives for high quality electronic paper (e-paper), and in ultra-
i ltrating membranes (water purii cation).
h e research and process development by Innventia [70] in recent times has resulted
in a sharp drop in the energy requirement for manufacturing nanocellulose in the last few
years. With new pre-processing methods, they have lowered the energy consumption
