Rice Husk Ash (RHA) was prepared using Charcoal from burning The complete utilization of rice husk for production of rice husk ash carbonized rice husk for steel industryIn China, the yield of rice husk reached 56 516.50 × 10 4 t in 2016. As usually, a part of rice husk was used as the poultry fee. However, most of rice husk was threw away as waste materials, which was harmful for environmental. The high value utilization of rice husk is an urgent and promising in China.The high silica content of rice husk ash makes it a good additive for the steel and concrete industries. To a lesser degree, rice husk ash is used as soil conditioner, activated carbon, insulator, and others.Rice husk Deelert processes and packages Rice Husk Ash for different industries such as cement and steel industry. By using consistent and quality process Deelert can create RHA (rice husk ash )that has low residule carbon content and high silica content which is necessary in the steel industry. With high silica contents our product can also be use for Cement and Fertilize.
