Nanocellulose is the smallest and sturdiest unit of biomass, produced from wood biomass and other low-cost sources, such as forestry and agriculture waste, bamboo and grasses. It can be used in a wide range of applications and its physical properties make it very attractive.
The United States Environmental Protection Agency (“EPA”) has determined that the CNC and the CNF are equivalent to cellulose and that their commercial production can begin immediately, without the need for additional testing.
Tests on lignin-coated nanocellulose types have shown the following positive impacts on the environment and human health:
“Low explosion risk” (as classified by the occupational health and safety agency);
Lowest oral toxicity category according to the Globally Harmonized System for Risk Communication;
Classified as non-irritating to skin and eyes;
EPA classification of “Practically non-toxic” based on acute environmental toxicity tests for bacteria, algae and invertebrates;
“... One of the least toxic nanomaterials ever tested by our laboratory”.
Types of Nanocellulose
Nanocellulose is divided into two types: CNF and CNC;
Nanocellulose can be a nanocrystal (CNC) or a nanofiber (CNF). The CNF is a pseudoplastic and has the property of some gels or fluids. The CNC is obtained from native fibers through acid hydrolysis;
Light and sturdy, with high optical transparency and low oxygen permeability.
