What is the use of rice husk?

Rice husk is the shell of rice, which will be peeled off during rice processing. Rice husk has many uses, including as fuel, fertilizer, feed and materials. First of all, rice husk is a cheap fuel, which can be used for power generation, heating and drying. It produces less waste gas in the combustion process than traditional fuels such as coal, which reduces environmental pollution. Secondly, rice husk can be used as organic fertilizer, and the organic matter and nutrients produced by its decomposition can promote plant growth and improve soil quality. In addition, rice husk can also be used as animal feed, providing energy and fiber, reducing the use of plant feed. Finally, rice husk can also be used to make paper, fiberboard, biomass fuel and other products. The production of these products can reduce the demand for traditional wood, thus reducing deforestation.
