Rice husk from paddy (Oryza sativa) is one example of alternative material that has a great potential. Rice husk a major by-product of the rice milling industry, is one of the most commonly available lignocellulosic materials that can be converted to different types of fuels and chemical feedstocks through a variety of thermochemical conversion processes. Rice husk is an agricultural residue abundantly available in rice producing countries.The husk surrounds the paddy grain. During milling of paddy about 78 % of weight is received as rice, broken rice and bran. Rest 22 % of the weight of paddy is received as husk.
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 100% by ground rice husk. Other uses are in horticulture (soil aeration), animal bedding, and composites. We supply rice husk ground (GRH) and unground (RH). Several ground particle sizes are available, the most common being 2 & 3mm and below.
