Whether these rice husks are of value or not is a topic worth exploring. Today we have summarized some information to specifically talk about the reuse of rice husks. The in-depth development and application fields of
Rice Husk are quite extensive. Its primary product can not only be used as a culture medium for edible fungi, as energy generation, and production of fiberboard and furfural , but also after deep processing, it can also produce fast food boxes, beauty cosmetics and other food and chemical products that are conducive to environmental protection and health.
Rice husks are rich in lignin , pentosan and silica . They are good raw materials for preparing white carbon black, activated carbon and high modulus potassium silicate . Activated carbon produced from rice husks as raw materials is not only low in cost, but also has less miscellaneous content, and is particularly suitable for the food industry. The silicon in rice husks is burned under certain conditions and can form porous amorphous silica particles, which has a great absorption surface and activity, and can be used as raw materials for a variety of carriers or advanced composite materials. Rice husks also contain a variety of vitamins, enzymes and food fibers, which play an important role in promoting skin metabolism; another active ingredient in rice husks, inositol , has a certain effect on preventing rectal cancer, breast cancer, , etc.
At present, foreign countries have successfully developed activated carbon, white carbon black, water glass , high-purity silicon, xylose , levulinic acid and a variety of cosmetics using rice husks. There are many unknown components in the rice husk, and its development still has great potential and its utilization prospects will be very broad.
