*Please note that it is normal to have bugs in rice husk / fine husk and it can't be avoided.
Rice husk, also called rice hull, is the coating on a seed or grain of rice. It is formed from hard materials, including silica and lignin, to protect the seed during the growing season. Each kg of milled white rice results in roughly 0.28 kg of rice husk as a by-product of rice production during milling.
Rice Husks can be put to use as building material, fertilizer, insulation material, or fuel
