The Vietnamese word "trấu" refers to rice husk. Rice husk is the hard protective covering of grains of rice, which is usually removed during the milling process. It is often a byproduct of rice production and is not typically consumed as food, but it has various uses in agriculture and industry.
In more advanced contexts, trấu can be discussed in terms of its environmental benefits. For example, it can be used as a natural fertilizer or as a material for making biofuels. Some people may also talk about using rice husk for insulation in building materials or as a component in biodegradable products.
While trấu generally means rice husk, in some regions or contexts, it might refer to other agricultural waste or the concept of something that is left over after processing. However, the primary meaning remains focused on rice husk.
Understanding the word trấu is important for discussing rice cultivation and its byproducts in Vietnamese.
