Cellulose fiber and cellulose nanofiber are made from kenaf, vegetable peels, old newspapers, trees, etc. Cellulose fiber is a better insulator than glass wool and absorbs moisture inside the house and expels it outside, making the house It is resistant to mold and mildew. There are also high-tech products such as cellulose nanofiber batteries, cellulose nanofiber semiconductors, and diamond semiconductors made from artificial diamonds made from sake, tequila, vodka, and other liquors, which are currently under research. Cellulose nanofibers are five times harder and stronger than steel. It is 1/5 the weight of steel. Since it is transparent, it can be used as a substitute for glass. Since it does not rust, it can be used in place of reinforced steel frames, and if you mix cellulose nanofiber with ultra-low-shrinkage concrete, you can make a highly durable reinforced concrete that will not rust or crack for thousands or tens of thousands of years. Cellulose nanofiber is highly recyclable. It hardly deteriorates when recycled.
To quote from WikiPedia
In August 2020, a low-cost, low-energy method to obtain cellulose nanofibers by oxidizing paper pulp using a bleaching solution of highly concentrated sodium hypochlorite to create cellulose oxide with excellent fiber breakdown properties, and then agitating and mixing the oxide to proceed with nanofiber breakdown. 10].
This method does not emit carbon dioxide. It is friendly to the earth's natural environment because it does not emit carbon dioxide. Other methods of miniaturization.

Oji's phosphate esterified CNF
The Oji Group has adopted the phosphate esterification method as an effective method to reduce the energy used in the production of finer products. This method enables the production of high quality (high transparency, high viscosity, and thixotropy) CNF with higher production efficiency than conventional methods. 2017 saw the start of operations of a CNF demonstration manufacturing facility within Oji Paper's Tomioka Mill.
Currently, we are manufacturing a variety of CNFs, including transparent CNF slurry "AUROVISCO" and coarse CNF slurry, and are actively providing samples and developing applications for commercialization.
Fibrillation Mechanism
Cellulose nanofibers can be made either conductive or non-conductive, depending on how the materials are mixed. It is lightweight, strong, rust-free, and can be made to conduct electricity, so it can be used in place of carbon in the body of a jumbo jet. Even if lightning strikes, if it is made to conduct electricity, it will not explode, so it is very safe.
The production cost of cellulose nanofiber is 1/10 that of iron and carbon.
Cellulose nanofiber can be used as a substitute for carbon, FRP bodies, and glass, which has high heat insulation properties and is resistant to breakage.
It can also be used to make carports for automobiles, balconies, bath units for bathrooms, glass windows, and window frames and glass sections for aluminum sashes.
