However, CS contains lignin and carbohydrates, like cellulose and hemicelluloses, which can be converted into a variety of usable
Although the ash content of rice straw and husks was very high (22.6% and 14.6%), probably due to the high Si content of rice plants, the ash content of rice bran was much lower (8.1%). The ash content of sorghum plantwas 5.8%. The percent by weight of some elements in the raw materials are shown in Fig. 4 and Table 1. Carbon content was high
The uses for rice husk are continually growing. Today it is increasingly used as biomass to fuel and co-fuel power plants. There are now many power plants in Asia powered by ground rice husk. ricehusk.com Pte Ltd. is leading the introduction of rice husk into
3.4.3. Rice Husk and Rice Husk Ash. Rice husk has good chemical stability, is insoluble in water, possesses a granular structure, and has high mechanical strength, which shows it is a good adsorbent material for removal of heavy metals from wastewater.

Biomass burning has a significant impact on global atmosphere chemistry since it provides large sources of carbon monoxide, nitrogen oxides and hydrocarbons. The waste products which are the main contributors to biomass burning are bagasse, rice straw and husk, cotton wastes, barley residue, maize stalks and leaves, and millet and sorghum stalks.
The rice husks are pyrolyzed in the absence of air at a temperature of 700-900°C and then fired at temperatures of 1500°C in an inert or reducing atmosphere . Therefore, the carbon/silica ratio of the pyrolyzed rice husks plays a vital role in the formation of silicon carbide.
