Nanotechnology-assisted production of value-added ...

Mechanical grinding through chipping, milling, and grinding reduces the cellulose crystallinity in biomass. Chipping breaks the biomass into 10–30 mm pieces, while milling and grinding reduce the size of biomass to 0.2 mm (Zakaria et al., 2014). The overall process leads to decrease in dimension and increase in aspect ratio of the particle.
